The aim of this study was to evaluate the relationship between respiratory functions and body compositions of elite athletes in alpine disciplines and cross-country skiing through their comparison. The study included 32 male athletes (age: 18.3±2 year, height: 172.1±6.05 cm, body weight: 65.73±10.79 kg, and body mass index (BMI): 22.91±2.80 kg/m2) within the scope of alpine disciplines and cross-country skiing. The heights of the athletes were measured with a stadiometer (Holtain, UK) with an accuracy of ±1mm. The weights of the athletes and BMI values were measured using a Tanita brand (BC, 418 Tanita, Japan) body composition analyzer with a precision of 100 grams. The respiratory function and respiratory muscle strength of the athletes were evaluated using a digital spirometer (Pony FX Cosmed, Italy). Pearson's correlation analysis was used to determine the relationships between respiratory functions and anthropometric structures of the groups. The results indicated that cross-country skiing athletes had higher averages in FVC, FEV1, FEV1/FVC, PEF, MIP, MVV, and MEP parameters compared to alpine discipline athletes, with only the MIP value being higher in alpine discipline athletes. The results revealed positive correlations between age and FVC (0.563), FEV1 (0.521), PEF (0.679), and MVV (0.511) in cross-country skiing athletes. Negative correlations were found between body weight and FEV1/FVC (r=0.578), FEV1/FVC (r=0.545), height and MVV (r=0.541), and body mass index and FEV1/FVC (r=0.541), FEV1/FVC (r=0.676) in cross-country skiing and alpine discipline athletes, respectively (p0.05). In order to achieve maximum performance, it is very important to identify and keep under control the factors affecting respiratory functions. The current study demonstrated that the characteristics of the sport have an impact on physiological changes in the respiratory system and also affect body compositions and respiratory functions.

Soccer is one of the sports where performance is shaped by the coming together of numerous variables. The importance of strength, a physical variable that determines performance, is thought to be as crucial as the experience levels of athletes, which are also considered important for performance. The present study aimed to compare the isokinetic strength characteristics and soccer experience of professional league (PRL) and amateur league (AML) soccer players. After recording variables such as total playing seasons and weekly training sessions, isokinetic strength measurements were conducted at angular velocities of 60°/sec and 180°/sec. The outcomes revealed that PRL players engaged in significantly more weekly training sessions and had accumulated a higher total number of playing seasons than their AML counterparts (p

The aim of the study was to compare differences in body composition, lower extremity strength, and anaerobic power characteristics among professional football players at different league levels. A total of seventy-one volunteer players aged between eighteen and thirty-five years (mean age: 23.14 ± 4.23 years) participated in the study, representing the Super League, 1st League, and 2nd League. The participants' body compositions were measured using the DXA (Hologic QDR Series, Delphi A model, Bedford, MA, USA) bioelectrical impedance analyzer, CounterMovement Jump (CMJ) strength with the ChronoJump Smartspeed Mat (INEFC, Barcelona), and Running Anaerobic Sprint Test (RAST) tests were conducted. ANOVA was used to compare multiple groups, and the Duncan multiple comparison tests were conducted in cases where differences were observed to determine which group the difference favored. The results revealed that Super League players statistically possessed more significant values in body composition compared to 1st and 2nd League players and demonstrated significantly higher values in terms of jump height, maximum force output, and anaerobic power compared to 1st and 2nd League players (p

The impact of the practice of physical activities on burnout and its dimensions remains very little documented among students living in subaerial African countries. The present study was to determine the impact of the level of physical activities on Burnout. In a cross-sectional analytical study, students from the Faculty of Medicine of the University of Kinshasa were recruited by convenience in the period from February 1 to August 1, 2023. The parameters of interest included intensity, frequency, duration of the practice of physical activities and the dimensions of Burnout. Analysis of Variance (ANOVA) was used to research the influence between the intensity, frequency and duration of physical activity practice on emotional exhaustion, depersonalization, lack of personal accomplishment and burnout syndrome. The moderate and high level of physical activity practice significantly reduces emotional exhaustion by -14 (30.08 ± 13.04 vs 16.10 ± 10.38; p < 0.001), depersonalization by -7 (12. 45 ± 6.42 vs 5.89 ± 5.99; p < 0.001), burnout of -17 (28.17 ± 10.05 vs 11.00 ± 8.47; p < 0.001) and increases the personal accomplishment of students of the faculty of medicine of +31 (42.00 ± 10.7 vs 11.00 ± 8.47; p < 0.002). The duration of the practice of physical activities of 30 minutes or more positively influences personalization in 28% (p < 0.001), 75% personal accomplishment (p < 0.003) and 63% burnout (p < 0.004). Furthermore, the frequency of 3 or more times per week of practicing physical activities positively improves emotional exhaustion by 56% (p < 0.001), professional accomplishment by 79% (p < 0.002) and 83% by burnout (p < 0.001). Young medical school students with burnout are inactive and sedentary. The latter are associated with a decrease in personal accomplishment and an increase in burnout syndrome. The duration of physical activities of 30 to 45 minutes per day practiced three or more times per week positively improves emotional exhaustion, personalization, and personal accomplishment and burnout syndrome. The dissemination of information programs, particularly to medical students, seems urgent.

Yoga, a practice originating in India thousands of years ago, has gained immense popularity today and its effects are under scrutiny. Numerous studies demonstrate the positive impact of various types of yoga on human physiology. Specifically, research highlights the ability of yoga to mitigate stress and anxiety, as well as increase serotonin and dopamine hormones, facilitating healthy coping mechanisms in modern living. For a healthy lifestyle, yoga can be an important addition to a nutritious diet. While numerous studies have reported on the positive effects of yoga, its complete impact has yet to be fully understood. It may be recommended that the studies planned to be addressed in the future on the subject should be carried out for a specific health problem, should have a methodologically good and high quality structure and the sample size should be kept large. This review found that yoga has significant positive effects on anxiety and depression. It also increases hormones such as serotonin and dopamine in the body, which can lead to a more positive outlook. However, the review found statistically insignificant decreases in fasting blood glucose levels, postprandial blood glucose levels, and HbA1c. Additionally, yoga was found to significantly improve quality of life.

This study compared the effects of 12 weeks of aerobic training against baseline data of People Living with Human Immunodeficiency Virus (PLWH) Cluster of Differentiation 4 (CD4) cell count, and Health-Related Quality of life (HRQoL) (Physical-health Component Summary (PCS) and Mental-health Component Summary (MCS)). A within-subject quasi-experimental multimethod design was used. There was purposive sampling of participants on Highly Active Antiretroviral Therapy (HAART) under Botswana Network of People Living with HIV/AIDS (BONEPWA). The 28 participants (23 females and 5 males) who met the inclusion criteria were of age 18 to 45. After 6 weeks, one female dropped out of the study. Participants were subjected to 12 weeks of aerobic training, three times a week for 60 minutes per session. The significant differences between CD4 cell count and the HRQoL variables at baseline and week 12 of the participants were compared using the paired t-test. All analysis was done using Statistical Package for the Social Sciences (SPSS) version 24.0 software. The alpha value was set at p0.05) improvements in CD4 count and PCS measures after intervention. PLWH can be advised to engage in regular aerobic training 3 times a week for 60 minutes especially when on HAART. The research is relatively preliminary; therefore, there could be some replication of the study by other researchers.

This systematic review aims to demonstrate that coenzyme Q10 (CoQ10) supplementation may be an effective molecule in improving exercise performance and recovering muscle damage, improving antioxidant capacity, and suppressing inflammatory processes. The study covers the literature in PubMed, Google Scholar, Web of Science and Scopus databases from 2011 to 2023. The final review was conducted on June 6. In the literature analysis, eight keywords (exercise, oxidative stress, CoQ10, muscle damage, inflammation, skeletal muscle, heart muscle, and performance) were employed to investigate the publications. The full texts of 362 full texts of articles were included in this study. These were analyzed according to the PRISMA reporting criteria. In the analysis, one study was conducted with experimental animals, two studies were conducted with male and female participants, and 12 studies were conducted with only male participants. Participants in twelve studies were well-trained. However, two studies were conducted with a sedentary group. In addition, CoQ10 supplementation was present in all studies. CoQ10 supplementation was between 5-60 mg/kg in 4 studies and 100 mg/kg and above in the remaining 10 studies. Antioxidant capacities and inflammation markers were among the parameters of most interest. There were fewer studies on skeletal and cardiac muscle damage and performance markers. CoQ10 supplementation during intense exercise elevates plasma CoQ10 and antioxidant levels while reducing inflammation markers. Additionally, it enhances contractile function in sarcomeres and cardiomyocytes. Nevertheless, additional studies are necessary to comprehensively as certain CoQ10 impact on athletic performance.

The aim of this study was to conduct a systematic review of research that investigates coordination abilities in basic individual sports, such as athletics, gymnastics, climbing, and swimming. The relevant sports that have a process of identifying very young talents are precisely these basic individual sports. The following electronic databases were used: Web of Science and PubMed. A total of 16 studies met the criteria for participation in this study. Since only a few studies have been done on this topic, this review included studies for the last 30 years. The sample of respondents in the included studies consisted of both males and females, and the total number was 642. The study findings indicate that coordination is a crucial motor ability with a significant impact on athletic success in youth. The level of coordination abilities increases with sports experience, so the development of coordination should be one of the priorities in the training process of gymnasts, athletes, sports climbers and swimmers in younger sportsman ages.
