Different whole body HIIT protocols do not promote different muscle thickness and functional adaptations among healthy physically active subjects

IntroductionDespite robust evidence on the benefits of high intensity interval training using body weight (WB-HIIT), the effects of different training configurations on morpho-functional adaptations are still unclear. Therefore, the aim of the present study was to assess the effects of two distinct WB-HIIT protocols on morphological and general fitness adaptations in healthy active young individuals.MethodsThirty-four participants (22 males and 12 females) were randomly assigned to one of the following groups: 30 s of all-out effort interspersed with 10 s of passive recovery (G30 × 10, n = 17) or 40 s of an all-out effort interspersed with 20 s of passive recovery (G40 × 20, n = 17). Nine exercises were performed for both protocols, in two weekly sessions, during a 6-week intervention period. Morphological (ultrasound-derived muscle thickness of the vastus lateralis [MTVL]) and general fitness (muscle endurance and maximal oxygen consumption) assessments were performed at pre- and post-intervention moments.ResultsBoth training protocols elicited significant improvements in all dependent variables (p < 0.05), with no significant between-group differences.ConclusionRegardless of the training configuration, both WB-HIIT programs serve as time-efficient strategies to induce changes in muscle thickness of the vastus lateralis and functional adaptations in healthy, physically active young individuals.

Do Power Meter Data Depend on the Device on Which They Are Collected? Comparison of Eleven Different Recordings.

This study evaluated the influence of cycle computers on the accuracy of power and cadence data. The research was divided into three phases: (1) a graded exercise test (GXT) at different constant loads to record power and cadence data; (2) a self-paced effort lasting 1 min to measure mean maximal power output (MMP); and (3) a short all-out effort. Eight cyclists completed the GXT, ten participated in the 1-min test, and thirty participated in the sprint effort. All participants pedaled on a controlled-resistance cycle ergometer, and the data were recorded using the ergometer itself and ten synchronized cycle computers of the same brand, configured to record at 1 Hz. The results showed minimal variations in power and cadence between devices during the GXT, suggesting adequate accuracy for constant efforts lasting a certain duration. However, in self-paced and high-intensity efforts (1-min and short all-out efforts), significant differences were observed between several devices, particularly in cadence and mean power, highlighting the relevance of device selection in these contexts. These findings suggest that, while variations in constant efforts may be negligible, in short-duration, high-intensity activities, the choice of device may be crucial for the accuracy and reliability of the data.

Effects of 2 Combined Training Protocols on the Aerobic and Anaerobic Fitness, Technical Skills, and Psychophysiological Responses in Young Soccer Players.

Kilit, B, Chmura, P, Arslan, E, Soylu, Y, and Radziminski, Ł. Effects of 2 combined training protocols on the aerobic and anaerobic fitness, technical skills, and psychophysiological responses in young soccer players. J Strength Cond Res 39(1): 86-93, 2025-The study compared the effects of combining small-sided soccer games (SSGs) with high-intensity interval training (HIIT) and repeated sprint training (RST) on aerobic and anaerobic fitness, technical skills, and psychophysiological responses in young soccer players. Thirty-two male, adolescent, soccer players (aged 13.5 ± 0.3 years) were randomly divided into either the SSGs + HIIT group ( n = 16) or the SSGs + RST group ( n = 16) for combined training 3 times per week for 6 weeks. The players in the SSGs + HIIT group performed 12-18 minutes of runs at intensities (90-95%), whereas the players in the SSGs + RST group consisted of 3-4 sets of 5-7 times 15-m shuttle sprints (all-out efforts). Both training groups played 4 bouts of 2-a-side or 4-a-side SSGs with various game formats at 2-day intervals. Psychophysiological responses were determined during and after all training sessions. Before and after training interventions, the following physical performance tests were used: 5- to 30-m sprint time, countermovement jump, triple-hop distance, zigzag agility with the ball and without the ball, repeated sprint ability (RSA), 30-15 Intermittent Fitness Test, 3 corner run test, speed dribbling ability (SDA), Yo-Yo Intermittent Recovery Test Level 1, and Y-balance test. Our main findings were that the SSGs + RST group demonstrated greater improvement in 5-m sprint time, SDA time, and RSA in the meantime compared with the SSGs + HIIT ( p ≤ 0.05, d values ranging from 1.50 to 2.25). Moreover, the SSGs + RST group showed greater improvement in agility test responses ( p ≤ 0.05, d values ranging from 2.13 to 2.34) than the SSGs + HIIT group. However, the SSGs + HIIT induced higher perceived exertion, mental effort, and lower greater physical enjoyment meaningfully compared with the SSGs + RST ( p ≤ 0.05, d values ranging from 6.04 to 6.67). In conclusion, these results demonstrate that the SSGs + RST is an effective training program to improve young soccer players' speed and agility-based performance responses.

The Effects of High-Intensity Interval Training on Cardiometabolic Health in Children and Adolescents: A Systematic Review and Meta-Analysis.

High-intensity interval training (HIIT) interventions are typically prescribed according to several laboratory-based parameters and fixed reference intensities to accurately calibrate exercise intensity. Repeated all-out printing efforts, or sprint interval training, is another form of HIIT that is prescribed without individual reference intensity as it is performed in maximal intensities. No previous study has performed a systematic review and meta-analysis to investigate the effect of HIIT and SIT on cardiometabolic health markers in children and adolescents. Moreover, previous studies have focused on single risk factors and exercise modalities, which may restrict their ability to capture a complete picture of the factors that could be affected by different interval interventions. The present study aimed to conduct a novel meta-analysis on the effects of HIIT and SIT on multiple cardiometabolic health markers in children and adolescents. An electronic search was conducted in three main online databases including PubMed, Web of Science, and Scopus were searched from inception to July 2024 to identify randomized and non-randomized control trials comparing HIIT and SIT versus the non-exercise control group in children and adolescents with mean age ranges from 6 to 18 years old on cardiometabolic health markers including fasting glucose and insulin, insulin resistance, triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), systolic blood (SBP) and diastolic blood (DBP) pressures. Standardized mean differences (SMD), weighted mean differences (WMD), and confidence were calculated using a random effect model. HIIT decreased insulin, insulin resistance, TG, TC, LDL, and SBP and increased HDL but did not decrease glucose and DBP. Furthermore, subgroup analyses show that insulin and insulin resistance were decreased by sprint interval training (SIT) and in those with obesity. Lipid profile mainly is improved by SIT and in those with obesity. Also, SBP was decreased by SIT and in those with obesity. Our results prove that HIIT is an effective intervention for improving cardiometabolic health in children and adolescents, mainly those with obesity. Specifically, SIT is an effective interval training mode in children and adolescents.

Climate change shocks and crop production: The foodgrain bowl of India as an example

Global warming is causing climate change (CC) characterized by increased frequency of heatwaves, droughts, erratic rains, hailstorms, cloudbursts, floods, landslides etc. The CC has already adversely affected ecosystems. In spite of efforts to mitigate greenhouse gas (GHG) emissions, which lead to warming, the global temperature during 2011–20 was 1.1°C above that during pre-industrial era. The projections are that warming will continue to increase and adverse effects will intensify particularly in developing countries like India. In India a number of studies have recorded wide spatial variability in rainfall, though, many reported a general overall negative trend since mid-20th century. Further, varying pattern of rainfall has been recorded in three agroclimatic regions of Punjab state, the granary of India. Unseasonal rains followed by spiked temperature during winter (rabi) season of 2021–22 reduced wheat (Triticum aestivum L.) yield in Punjab by 651 kg/ha and by 301 kg/ha in Haryana compared to 2020–21. Further, the grain was of lower quality. During rainy (kharif) season of 2022, Southern Rice Black-streaked Dwarf Virus (SRBSDV), appeared for the first time in Punjab and Haryana. Some farmers ploughed the affected fields. Adverse weather during rabi 2022–23 also, reduced the wheat yield (143–150 kg/ha) in these states. At the national level, erratic weather during rabi 2021–22 and kharif 2022 caused losses of about 3 mt of grain of each of wheat and rice (Oryza sativa L.). The projected increased adverse effects due to intensified CC include food insecurity. Thus, there is an emergent need to accelerate implementation of adaptation and mitigation strategies in agriculture. The adaptation options include cultivar improvement, conservation agriculture altering growing seasons, crop diversification and sustainable soil, and water resource management. In the process of adaptive management of crop production, adjusting sowing dates and breeding cultivars having varying duration in consonance with CC has been one of the central aspects. Shifting sowing dates to find appropriate crop cultivation season is a low-cost measure. However, cultivar development is time and resource consuming. Novel biotechnological tools enable fast cultivar development with precision, and facilitate mobilization of genes from wild-weedy relatives, which are rich in genes conferring resistance/tolerance to biotic and biotic stresses, required to combat CC challenge. In view of CC stress on water resources, improving water-use efficiency (WUE) has gained importance. Sensor-based micro-irrigation/fertigation has great potential to enhance water and fertilizer-use efficiency. Similarly, the application of other smart technologies like nanotechnology, sensor-based pesticide application, bio-fertilizers and bio-pesticides, need to be mobilised. In view of agro-ecological diversity in India, right-sized regionspecific technology packages have to be developed implying that crop research will expand exponentially. This needs strengthening of human resources and institutional infrastructure, expanding and linking basic and applied researches, and fortifying inter-disciplinary/inter-institutional collaborations to develop and diffuse technology innovations. Enabling factors include enhanced funding and international cooperation. All-out efforts are needed to have more climate-resilient agriculture.

Repeated sprint training in hypoxia induces specific skeletal muscle adaptations through S100A protein signaling.

Athletes increasingly engage in repeated sprint training consisting in repeated short all-out efforts interspersed by short recoveries. When performed in hypoxia (RSH), it may lead to greater training effects than in normoxia (RSN); however, the underlying molecular mechanisms remain unclear. This study aimed at elucidating the effects of RSH on skeletal muscle metabolic adaptations as compared to RSN. Sixteen healthy young men performed nine repeated sprint training sessions in either normoxia (FIO2 = 0.209, RSN, n = 7) or normobaric hypoxia (FIO2 = 0.136, RSH, n = 9). Before and after the training period, exercise performance was assessed by using repeated sprint ability (RSA) and Wingate tests. Vastus lateralis muscle biopsies were performed to investigate muscle metabolic adaptations using proteomics combined with western blot analysis. Similar improvements were observed in RSA and Wingate tests in both RSN and RSH groups. At the muscle level, RSN and RSH reduced oxidative phosphorylation protein content but triggered an increase in mitochondrial biogenesis proteins. Proteomics showed an increase in several S100A family proteins in the RSH group, among which S100A13 most strongly. We confirmed a significant increase in S100A13 protein by western blot in RSH, which was associated with increased Akt phosphorylation and its downstream targets regulating protein synthesis. Altogether our data indicate that RSH may activate an S100A/Akt pathway to trigger specific adaptations as compared to RSN.

Climate, food (in)security and conflict in the Bangladesh delta: Myths and puzzles

Bangladesh is customarily presented as a poster child for climate change and conflict given its dense population and susceptibility to climate variability. This vulnerability exacerbates existing challenges such as food insecurity and conflict potential. Crises like pandemics and conflicts are external drivers stressing already compromised domestic governance, such as violent politics, poor rule of law, and corruption, further compounding the challenges of land and water resource management and affecting food (in)security in Bangladesh. While we will argue that Bangladesh’s all-out (‘securitised’) efforts to achieve food security are largely successful and there is no evidence of climate conflict related to food, this does not obviate very real food security challenges in remote areas. However, these have not built up to the sense of frustration associated with food riots or community violence. Navigating the possible linkages between climate, food (in)security, and conflict requires debunking common myths and identifying unresolved research puzzles in Bangladesh’s context. These myths promote the oversimplification of complex issues and may lead to misinformed policies and actions. Future research needs to be focused on understanding how climate factors interact with local economic, political, and social dynamics, including governance mechanisms, religious and ethnic tensions, economic inequality, grievances, and political exclusion.

Stryd biomechanical parameters as indicators of running economy and performance

The interplay of biomechanical and neuromuscular aspects aids in the conversion of power production in running performance, and when combined with metabolic factors, these aspects may lead to improved running economy (RE). Therefore, the purpose of this study is to determine the association between the Stryd Power Meter foot pod metrics with RE and performance. Fifteen high-caliber male athletes completed two treadmill running sessions. First, RE was determined at 10 and 12 km/h. Second, two all-out efforts of nine and three minute duration were completed. At 10 km/h, the simple and stepwise multiple linear regression analysis revealed that form power (FP) was the best RE predictor (adjusted R2 = 0.464; p = 0.005) followed by vertical oscillation (VO) ( R2 = 0.424; p = 0.005) and ground contact time (GCT) ( R2 = 0.363; p = 0.010). At 12 km/h, such regressions confirmed that GCT was the best RE indicator (adjusted R2 = 0.222; p = 0.043) followed by FP (adjusted R2 = 0.213; p = 0.047). During the nine and three minute all-out effort sessions, GCT was the best performance predictor ( R2 = 0.491; p = 0.002 and R2 = 0.380; p = 0.014, respectively). The biomechanical factors of GCT and FP are good indicators of RE and running performance.

Are there specific molecular adaptations of skeletal muscle to repeated sprint training in hypoxia?

Introduction
 Athletes increasingly engage in repeated sprint training that consists of repeated short all-out effort (< 10 s) interspersed by short recoveries (< 60 s). When performed in hypoxia (repeated sprints in hypoxia, RSH), it may lead to greater training effect than in normoxia (RSN). However, the mechanisms underlying this superior training effect of RSH are unclear. Specifically, the role of muscle metabolic response to RSH is still debated and results are heterogeneous. Clarifying the molecular pathways of skeletal muscle adaptations to RSH may thus provide new insights into the role of hypoxia-induced response to training.
 Methods
 Two groups of healthy young men (randomized) performed three training sessions/week for three weeks. Each training session consisted in six series of six sprints (6 s effort/24 s rest) in either normoxia (RSN, n = 7) or normobaric hypoxia (FiO2 = ~13%, RSH, n = 9). Before and after the training period, vastus lateralis muscle biopsies, a repeated sprint ability (RSA) test and a Wingate test were performed. Metabolic muscle adaptations were studied with proteomics and western blotting.
 Results
 RSN and RSH similarly improved power output (p < 0.05) during the RSA test (RSN: + 7.2 ± 7.7% vs. RSH: + 7.9 ± 6.6%) and the Wingate test (RSN: + 1.3 ± 3.6% vs. RSH: + 4.4 ± 5.0%). Proteomics revealed a decrease in several processes involved in oxidative phosphorylation, confirmed by Western Blot with a reduction (p < 0.05) in complexes I (- 19 ± 30%) and V (- 15 ± 24%) protein levels in response to both RSN and RSH. RSN and RSH increased (p < 0.05) protein levels of the hypoxia inducible factor 1α (HIF-1α, + 111 ± 50%) and vascular endothelial growth factor A (VEGFa, + 91 ± 60%). Protein levels of the glycolytic enzyme hexokinase II increased (+ 119 ± 183%, p < 0.05) after both training types. Only RSH induced increased glucose transporter 4 (GLUT4, + 31 ± 18%, p < 0.05) protein level, suggesting specific glycolytic adaptations in response to hypoxia, supported by proteomics data. This specific adaptation may be triggered through the signaling of S100A protein family as we observed an increased S100A13 protein level (+ 467 ± 353%, p < 0.05) and Akt phosphorylation (+ 21 ± 21%, time x group interaction, p < 0.05) as well as several other S100A proteins in proteomics only after RSH training.
 Discussion/Conclusion
 To conclude, RSH did not exhibit in greater performance improvement compared to RSN. However, it further improved the glycolytic phenotype compared to RSN, possibly through specific S100A13 proteins signaling. Thus, we suggest that the reported superiority of RSH to RSN in the literature may stem from superior glycolytic adaptations triggered through the activation of a specific pathway involving S100A13 protein. The potential role of S100A13 protein in skeletal muscle adaptative responses to exercise is novel and the present results open new research perspectives in this field.

3-min All-out Test to Evaluate Aerobic and Anaerobic Indexes in Court Team Sports.

This study aimed to test the reproducibility of the 3-min all-out effort applied using shuttle running and compare its values to aerobic parameters. On the first day, 14 futsal players underwent an exhaustive test to determine the maximal incremental speed (MIS) and anaerobic threshold (AnT). On the second day, the participants performed the 3-min all-out effort (n=14), which was repeated after 48 h (third day) to test its reproducibility (n=11). Peak oxygen consumption (V̇ O2PEAK) and peak blood lactate concentrations ([La-]) were determined from 3-min all-out efforts performed through a 20-m shuttle run on the official court. The distance covered, mean speed, and critical speed (CS) during the 3-min all-out presented direct relationships with aerobic parameters determined through the incremental test (r>0.62). The distance covered above CS (D') presented a direct relationship with peak lactate concentrations induced by a 3-min all-out effort (r=0.81). Despite the acceptable levels of reproducibility observed for most of the 3-min all-out variables, the minimal detectable change for D' was high (72%). Our results demonstrated the potential use of mean speed to evaluate aerobic fitness. However, the applicability of the 3-min all-out shuttle run test to monitor training adaptations should be avoided, at least in nonexperienced athletes.

Business Management Model of Private and Public News Channels in Pakistan: A Case Study of GEO News and PTV News

Purpose: The chief purpose of this study was designed to explore the phenomenal changes of business management models of the private and public news channels in Pakistan. The rationale behind this objective was to explore changing business approaches as adopted by the private news channel like Geo News and the public news channel like PTV News. The advent of the social media has altogether changed the landscape for the traditional media including newspapers and news channels, therefore, it seemed quite appropriate to explore new strategies for enhancing business for news channels in Pakistan. 
 Design/Methodology/Approach: The study employed in-depth interviews qualitative method to collect qualitative data from different patterns of data for major themes. Qualitative Content Analysis was partially employed to minimize large stream of data into small chunk and analyze data accordingly.
 Findings: The study found out that the state-run news channel like PTV News was solely relying for financial support on the federal and provincial governments. Accordingly, the PTV News was providing absolute coverage to public departments and enhancing image of the ministers of the ruling political party and their ministries to enhance their public trust. However, the private news channel like GEO News has to make all-out efforts on advertising agencies, real estate sectors, multi-national companies, national and international corporations to meet its financial besides enhancing business of the Channel. Reciprocally, the private sector providing huge funding to GEO News has some sort of influence on its editorial content and news coverage thus compromising freedom of express to some extent. 
 Implications/Originality/Value: The study has drawn a visible line between financial expenditure and its impact on news coverage and editorial policy. PTV News was providing absolute coverage to public departments due to financial dependency, whereas the GEO News was providing coverage to all political parties and other public and private sector with slight difference. However, the freedom of expression of the GEO News was compromised to some extent because of financial dependency.

A Systematic Review and Meta-Analysis of Wearable Satellite System Technology for Linear Sprint Profiling: Technological Innovations and Practical Applications.

Cormier, P, Meylan, C, Agar-Newman, D, Geneau, D, Epp-Stobbe, A, Lenetsky, S, and Klimstra, M. A systematic review and meta-analysis of wearable satellite system technology for linear sprint profiling: technological innovations and practical applications. J Strength Cond Res 38(2): 405-418, 2024-An emerging and promising practice is the use of global navigation satellite system (GNSS) technology to profile team-sports athletes in training and competition. Therefore, the purpose of this narrative systematic review with meta-analysis was to evaluate the literature regarding satellite system sensor usage for sprint modeling and to consolidate the findings to evaluate its validity and reliability. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, an electronic search of the databases, PubMed and SPORTDiscus (EBSCO), was conducted. Concurrent validity and reliability studies were considered, and 16 studies were retained for the review from the initial 1,485 studies identified. The effects on outcomes were expressed as standardized mean differences (SMDs, Cohen's d ) for each outcome (i.e., maximal sprint speed [MSS], the acceleration constant [τ], maximal theoretical velocity [ V0 ], relative force [ F0 ], and relative power [P max ]). Effect magnitudes represented the SMD between GNSS-derived and criterion-derived (i.e., radar and laser) and resulted in the following estimates: small for MSS ( d = 0.22, 95% CI 0.01 to 0.42), τ ( d = -0.18, 95% CI -0.60 to 0.23), V0 ( d = 0.14, 95% CI -0.08 to 0.36), relative F0 ( d = 0.15, 95% CI -0.25 to 0.55), and relative P max ( d = 0.21, 95% CI -0.16 to 0.58). No publication bias was identified in meta-analyzed studies and moderator analysis revealed that several factors (sampling rate and sensor manufacturer) influenced the results. Heterogeneity between studies was considered moderate to high. This highlighted the differences between studies in sensor technology differences (i.e., sampling rate, sensor fusion, and satellite network acquisition), processing techniques, criterion technology used, sprint protocols, outcome reporting, and athlete characteristics. These findings may be useful in guiding improvements in sprint modeling using GNSS technology and enable more direct comparisons in future research. Implementation of all-out linear sprint efforts with GNSS technology can be integrated into sport-specific sessions for sprint modeling when robust and consistent data processing protocols are performed, which has important implications for fatigue monitoring, program design, systematic testing, and rehabilitation in individual and team sports.

Fatigue Resistance Is Altered during the High-Hormone Phase of Eumenorrheic Females but not Oral Contraceptive Users.

To examine the effect of ovarian hormones and their synthetic equivalents on substrate utilisation and fatigue resistance during a race-specific cycling protocol. 17 well-trained female cyclists (9 eumenorrheic females, 8 oral contraceptive users), completed two experimental trials, in a randomised order, in their low (follicular/sugar pill) and high-hormone (luteal/active pill) phases. Each 91-min trial consisted of a 45-min moderate-intensity component (SMC) followed by 6-min of high-intensity (HIT) and then a fatigue resistance test (FRT): 6x1-min all-out efforts with 1-min active recovery. Meals, comprising carbohydrate (CHO) intake of 8 g.kg-1 body mass, were standardised 24-h pre-trial. An electrolyte-only solution was provided ad-libitum during each trial. In eumenorrheic females, a large reduction in average power during FRT was observed in the luteal phase (277 ± 31 vs. 287 ± 33 W; P = 0.032). Greater CHOox (~ 4 %, P = 0.020) during SMC and ventilatory inefficiencies during SMC and HIT (~ 7 %, P < 0.001) were also observed in the luteal phase. In OC users, despite some phasal changes in cardiorespiratory and metabolic data in SMC (~6% higher blood glucose and ~ 2% higher minute ventilation in active pill phase), none of the performance parameters in the FRT were different. Fatigue resistance was compromised only in high-hormone phase of the menstrual cycle, with eumenorrheic females likely susceptible due to increased CHO utilisation during SMC. Hormone-induced ventilatory inefficiencies may also have increased metabolic demand. These findings emphasise the need to maintain CHO availability for power production, particularly in high-hormone phases.

장기미제사건의 효율적인 수사방안에 관한 연구

In recent years, the increasingly wide-ranging and advanced pattern is a characteristic that is prominent not only in science and technology but also in violent crimes. Accordingly, investigative agencies such as the police are making all-out efforts to discover substantive truths and arrest criminals by introducing various investigative techniques and systems based on technical theories. However, in the case of cold cases that are more than 10 years old among violent cases, there are problems such as preservation of evidence and loss of investigation records, and representative cases that can no longer be investigated due to past statute of limitations have recently become an issue. The police have created a department in charge of cold cases at each local police agency and actively introduced scientific investigation techniques to detect criminals and solve cases, resulting in remarkable results. Examples include the murder of a Guro pub and the murder of a bank robber in Daejeon. In order to solve the cold case, a clear definition of the cold case and a dedicated team to solve the case are needed, but each local police agency still works as a temporary organization rather than a dedicated organization, so it is urgent to establish a more stable organizational system. In addition, there were system problems such as insufficient cooperative investigation with other agencies and difficulty in information sharing, criticism of the investigation as a show-type investigation by focusing investigators on cases where people are focused attention, and lack of expertise due to limited investigation resources. Accordingly, it is necessary to review the introduction of specialized investigators in cold cases in developed countries and actively utilize the introduction of dedicated investigation teams through permanent organizations and the introduction of professional investigator certification systems to expand cold case cooperation and efficiently operate crime analysis systems. Therefore, this study objectively selected important violent crime cases rather than 100% resolution of all cold case cases, and sought efficient investigation measures to focus on high-level investigative power as at the beginning of the case until the case is resolved.

The Decline Of Communism In Urdu Literature And Its Causes

The term ‘ ‘Communism’’ refers to a social system in which the means of production (land, minerals, factories, banks, trade, etc.) are collectively owned by the community, and their production is distributed according to the creative labor of the mental or physical workers. The most famous concept of Communism was given by Karl Marx and Frederick Eagles. According to them, any socialist society has three basic characteristics; The means of production are jointly owned, all decisions are made democratically,and goods are made for utility rather than profit. The facts and history tell us that a large majority of the people in Russia under the leadership of Lenin overthrew the most oppressive tsarist capitalist government and established a labor democracy and put all the means of production under the democratic control of the workers. An all-out effort was made to meet public needs by maximizing production and utilization. As a result of which this revolution made Russia not only a developed country in a few decades from a most backward country, which was even more backward than today's Pakistan, but also the Soviet Union emerged as the second largest superpower in the world. It happened for the first time in human history, but the concept of such a high and fastest development in the capitalist society is also absent, thanks to which the real freedom of man in the society was provided with solid material foundations, even our enemies acknowledged it. In this article we will discuss the decline of Communism in Urdu Literature and will find its causes.

Effects of Anaerobic Fatigue Induced by Sport-Specific Exercise on Postural Control in Highly-Trained Adolescent Road Cyclists

The aim of this study was to evaluate whether and how anaerobic fatigue induced by sport-specific exercise affects the postural control of highly-trained adolescent road cyclists. Twenty-three male athletes, aged 15–18 years, were included in the study. Postural control was assessed using the pedobarographic platform (bipedal upright stance, sequentially, with eyes open (EO) and closed (EC) for 60 s each, with a 30 s interval), before and 3 min after a 30 s all-out effort performed on the ergometer. The results showed significant increases in the 95%-confidence ellipse area (p-value 0.000 and 0.001 for EO and EC, respectively), as well as centre-of-pressure (CoP) range displacement in the anteroposterior (p-value 0.000 for both EO and EC) and mediolateral (p-value 0.011 and 0.001 for EO and EC, respectively) planes. In addition, a significant decrease in CoP mean sway frequency was observed (p-value 0.000 and 0.001 for EO and EC, respectively), but no changes were noted in CoP mean velocity (p-value 0.316 and 0.670 for EO and EC, respectively). In our study, it has been indicated that anaerobic fatigue induced by sport-specific exercise deteriorates postural control in adolescent cyclists. Moreover, cycling training may affect the quality of postural corrective reactions occurring in response to anaerobic fatigue.

Kinematic analysis of countermovement jump performance in response to immediate neuromuscular electrical stimulation.

The purpose of this study was to examine the effect of neuromuscular electrical stimulation (NMES) immediate intervention training on the countermovement jump (CMJ) height and to explore kinematic differences in the CMJ at each instant. A total of 15 male students who had never received electrical stimulation were randomly selected as the research participants. In the first test, the CMJ performance was completed with an all-out effort. The second experiment was best performed immediately to complete the CMJ operation after NMES for 30 min. Both experiments used a high-speed camera optical capture system to collect kinematic data. The results of this experiment revealed that after im-mediate NMES training, neuromuscular activation causes post-activation potentiation, which increases the height of the center of gravity of the CMJ and affects the angular velocity of the hip joint, the velocity and acceleration of the thigh and the shank and the velocity of the soles of the feet. The use of NMES interventional training based on the improvement of technical movements and physical exercises is recommended in the future.

Quality of government secondary school services in regional Bangladesh

This research investigated the service quality of government secondary schools (GSS) in Bangladesh. A mixed methods research design combining quantitative and qualitative methods was applied for gathering and analyzing data. Quantitative data was collected from 601 randomly selected clients using a structured interview schedule developed based on the five-dimensional SERVQUAL instrument. Qualitative data was obtained through focus group discussions and interviews of students, teachers, headteachers, guardians, assistant school inspectors, and the deputy director of secondary and higher education working in the selected region. Quantitative data were analyzed using descriptive statistics and bivariate analysis, while qualitative data was transcribed and labeled into emerging themes. The study found that the quality of secondary education in the GSSs of the study area failed to meet the demand of the clients in terms of all the quality dimensions of SERVQUAL, where t-values revealed a significant gap between expectation and perception in Tangibles, Responsiveness, Reliability, Assurance and Empathy dimensions. Data from qualitative methods showed that all the stakeholders agreed with the gap in tangibles and empathy dimension claimed by the respondents in the quantitative survey. However, teachers and guardians showed differential opinions regarding the gaps in responsiveness, reliability, and assurance. It was also found that 40% of the respondents were either neutral or dissatisfied with the education service of GSSs. Logistic regression output shows that among the dimensions of SERVQUAL, tangibles, responsiveness, assurance, and empathy can significantly influence a respondent’s overall satisfaction with GSS services. One-way ANOVA results show that schools from at least two districts differ significantly in terms of the mean score of overall satisfaction and the perceived mean score of tangibles, responsiveness, reliability, assurance, and empathy dimensions. The schools lack teaching, learning and recreational facilities such as laboratory, library, common room, and sports. The students did not receive individual need-based care for academic performance improvement and did not participate in lesson planning, preferring teaching methods and deciding assessment strategies. The teachers were not sufficiently skilled in delivering intelligible lectures and didn’t give time to students outside of formal classes. A sizeable gap in the SERVQUAL dimensions indicates that a comprehensive all-out effort is necessary to improve the service quality of GSSs. Consequently, improving teaching learning facilities, student participation in the lesson plan and deciding on teaching methods, teachers' training in pedagogy, and school-specific quality improvement measures are imperative.

A single session of whole-body cryotherapy boosts maximal cycling performance and enhances vagal drive at rest

Whole-body cryotherapy (WBC) has been reported to maximize physical recovery after exercise and reduce the ensuing muscle damage. In addition, WBC triggers cardiovascular responses leading to an increased vagal drive. Here we tested whether WBC may boost exercise performance as well as post-exercise recovery. Moreover, we compared the effects of WBC and exercise on sympathovagal balance and tested whether these two factors may interact. ECG was recorded in 28 healthy adults who underwent rest, all-out effort on a cycloergometer, 5 min recovery and again rest. After 3–5 days, WBC (3 min exposure to − 150 °C air) was applied and the whole procedure repeated. Total exercise duration was split into the time needed to reach peak power output (tPEAK) and the time to exhaustion (tEXH). The post-exercise exponential decay of HR was characterized by its delay from exercise cessation (tDELAY) and by its time constant (τOFF). Sympathovagal balance was evaluated by measuring HR variability power in the low (LF) and high (HF) frequency bands, both before exercise and after recovery from it. Sympathetic vs. vagal predominance was assessed by the sympathovagal index LFnu. Paired t-tests indicated that WBC increased tEXH and reduced tDELAY, speeding up the HR recovery. These results suggest that WBC may be exploited to boost exercise performance by about 12–14%. ANOVA on HR variability confirmed that exercise shifted the sympathovagal balance towards sympathetic predominance, but it also highlighted that WBC enhanced vagal drive at rest, both before exercise and after full recovery, covering ~ 70% of the exercise effect.

How fast and how well the Omicron epidemic was curtailed. A Guangzhou experience to share.

SARS-CoV-2 has ravaged the world and undergone multiple mutations during the course of the COVID-19 pandemic. On 7 April 2022, an epidemic caused by SARS-CoV-2 Omicron (BA.2) variant broke out in Guangzhou, China, one of the largest transportation and logistical hubs of the country. To fast curtained the Omicron epidemic, based on the routine surveillance on the risk population of SARS-CoV-2 infection, we identify key places of the epidemic and implement enhanced control measures against Omicron. Transmission characteristics of the Omicron variant were analyzed for 273 confirmed cases, and key places involved in this epidemic were fully presented. The median incubation time and the generation time were 3 days, and the reproduction number Rt was sharply increased with a peak of 4.20 within 2 days. We tried an all-out effort to tackle the epidemic in key places, and the proportion of confirmed cases increased from 61.17% at Stage 2 to 88.89% at Stage 4. Through delimited risk area management, 99 cases were found, and the cases were isolated in advance for 2.61 ± 2.76 days in a lockdown zone, 0.44 ± 1.08 days in a controlled zone, and 0.27 ± 0.62 days in a precautionary zone. People assigned with yellow code accounted for 30.32% (84/277) of confirmed COVID-19 cases, and 83.33% of them were detected positive over 3 days since code assignment. For the districts outside the epicenter, the implementation duration of NPIs was much shorter compared with the Delta epidemic last year. By blocking out transmission risks and adjusting measures to local epidemic conditions through the all-out effort to tackle the epidemic in key places, by delimiting risk area management, and by conducting health code management of the at-risk population, the Omicron epidemic could be contained quickly.
