Evaluating the athletics Athletes' Physical Fitness for PON XXI/2024 Qualification

Maluku's achievements can grow when the human resources of the coaches are enhanced to promote professionalism in the development of the science and technology of sports. Thus, the training process is not solely based on experience but on the science of training, which is studied in depth to support the better development of training athletes in the future. This study aims to determine how well Maluku athletic athletes' physical fitness is prepared for the PON XXI/2024 qualification round held in Solo, Central Java. This study used saturation sampling to study all the population samples. The instruments utilized in this study are the VO2 Max test, local muscle endurance test, biomotor ability test, speed and power tests, and local muscular stamina tests. The results revealed that the athletes' physical fitness to face a national event, in this case, the PON XXI/2024 qualification, is still considered medium, and the physiological condition belongs to the category of good based on the running time achievement that is close to the time achieved on the PON XXI qualification. The results of the study indicate that Maluku's athletic athletes have improved. However, the improvement has not surpassed the PB PASI time record. Despite the improvement in performance during training, the athletes had not reached the target to pass into the PON XXI Qualification. Keywords: evaluation, physical fitness, athletes’ achievement.

Objective: It was aimed to investigate the relationship between online gaming addiction, core muscle endurance, and reaction time in adolescents. Methods: The study was designed as a descriptive-correlational study and was conducted with 67 adolescents who play online games daily. The Online Gaming Addiction Scale, core muscle endurance tests, and hand and foot reaction time tests were performed. Results: The overall score of the Online Gaming Addiction Scale was 64.79±17.38, which corresponds as moderate negative reflections on the individual's life. A statistically significant difference was observed in online gaming addiction (p

Relationship between Body Mass Index, Dynamic Balance, and Core Muscle Endurance in Firefighter Candidates: A Cross-Sectional Study

This study aimed to examine the effects of Body Mass Index (BMI) on dynamic balance and core muscle endurance in firefighter candidates. In physically demanding professions, such as firefighting, understanding the impact of BMI on physical performance metrics is crucial for both occupational safety and effectiveness. The study was conducted with 89 firefighter candidates, with a gender distribution of 23.6% female (n=21, age 19.86±1.86 years, height 1.64±0.05 m, weight 59.47±7.26 kg) and 76.4% male (n=68, age 19.82±1.25 years, height 1.78±0.04 m, weight 74.36±12.09 kg). Within the scope of the research, the results of the BMI, balance, and core muscle endurance tests were evaluated. BMI was calculated based on measurements of participant height and weight. Dynamic balance performance was assessed using the Y-Balance Test, while core muscle endurance was measured using the plank test. The performances of the participants in both tests were recorded and subjected to statistical analysis. Pearson correlation analysis and multiple regression models were used to examine the relationships among BMI, dynamic balance, and core muscle endurance. The findings indicated that an increase in BMI has adverse effects on balance and core muscle endurance performance. Specifically, firefighter candidates with higher BMI values exhibited shorter plank durations (females: r=-0.63; p=0.002, males: r=-0.566; p

Post-exercise metabolic response to kettlebell complexes vs. high intensity functional training.

This study compared the magnitude of excess post-exercise oxygen consumption (EPOC) between kettlebell complexes (KC) and high-intensity functional training (HIFT) and identified predictors of the EPOC response. Active men (n = 11) and women (n = 10) (age 25 ± 6yr) initially completed testing of resting energy expenditure and maximal oxygen uptake (VO2max), followed by lower and upper-body muscle endurance testing. On two subsequent days separated by ≥ 48h, participants completed KC requiring 6 sets of kettlebell exercises (pushups, deadlifts, goblet squats, rows, and swings) with 60s recovery between sets, and HIFT requiring 6 sets of bodyweight exercises (mountain climbers, jump squats, pushups, and air squats) with 60s recovery. During exercise, gas exchange data and blood lactate concentration (BLa) were acquired and post-exercise, EPOC was assessed for 60min. Results showed no difference in EPOC (10.7 ± 4.5 vs. 11.6 ± 2.7 L, p = 0.37), and VO2 and ventilation (VE) were significantly elevated for 30 and 60min post-exercise in response to KC and HIFT. For KC and HIFT, HRmean and post-exercise BLa (R2 = 0.37) and post-exercise BLa and VE (R2 = 0.52) explained the greatest shared variance of EPOC. KC and HIFT elicit similar EPOC and elevation in VO2 which is sustained for 30-60min post-exercise, leading to 55 extra calories expended. Results show no association between aerobic fitness and EPOC, although significant associations were revealed for mean HR as well as post-exercise VE and BLa.

Human rights health care measures reporting physical fitness test for ages 6 to 17 with 10-year follow-up

Purpose This study aims to compare the physical fitness test results of Japanese children in 2008 and 2018 to narrow the gap between life expectancy and healthy life expectancy and extend healthy life expectancy. In addition, this paper sought to explore the potential of implementing health education programs as a new social context to promote race equality and human rights in health and social care. Design/methodology/approach This study was conducted in 2008 and 2018 in Nagano Prefecture, Japan. Physical fitness tests related to growth and development were administered to participants aged 6–17 years. Findings Physical fitness measurements in 2018, specifically those for walking ability and endurance, were significantly inferior to those in 2008. In a gender-specific analysis, boys outperformed girls in muscle strength, muscle endurance, walking ability and endurance tests, while girls outperformed boys in the balance test. Research limitations/implications Most of the junior and senior high school students who participated in the EO test exceeded the upper limit of 120 s, suggesting that the load of the measurement method is low and improvement is necessary. In 2018, a large variation in 6M results was observed among participants, possibly due to the differences in the level of seriousness during the 6M test. Therefore, to ensure that junior and senior high school students properly perform the EO and 6M tests, it is necessary to devise an effective method of implementation, such as changing the physical fitness test load. Originality/value Mere health education is ineffective to address health inequalities. Addressing structural factors is essential to avoid unintended consequences such as increasing the gap between groups of people. However, one way to extend healthy life expectancy is to improve overall health, including differences in the health status of groups due to differences in region and socioeconomic status.

Prevalence and Associated Factors with Frailty Using the Kihon Checklist among Community-Dwelling Older Adults in Taiwan.

Background and Objectives: Frailty in older adults is associated with adverse health outcomes. This study aimed to analyze the frailty status of community-dwelling older adults in Taiwan using the Kihon Checklist (KCL) and explore associations with demographic, physiological, and functional factors. Materials and Methods: In this cross-sectional study, 278 community-dwelling older adults were classified as robust, prefrail, or frail based on their KCL scores. Participants underwent physical fitness assessments including muscle strength and endurance tests, walking speed tests, and flexibility tests. One-way ANOVA and logistic regression analyses were used to examine differences and associations between frailty status and physical fitness indicators. Results: 36% of participants were robust, 47.1% prefrail, and 16.9% frail. The robust group significantly outperformed the prefrail and frail groups in the 30 s sit-to-stand test, 2.44 m sit-to-walk test, and walking speed (p < 0.001). The 2.44 m sit-to-walk test was a significant predictor of prefrailty (OR = 1.18, 95% CI = 1.02-1.36) after adjusting for other physical fitness indicators. Conclusions: Lower limb functional capacity, particularly in the 2.44 m sit-to-walk test, was significantly associated with pre-frailty among community-dwelling older adults in Taiwan. Early screening, the classification of frailty by the Kihon Checklist, and targeted interventions focusing on lower limb strength, endurance, and mobility are crucial for preventing and delaying frailty progression in older populations.

The effect of proprioceptive neuromuscular facilitation on individuals with text neck syndrome: A randomized controlled study.

Text neck syndrome is an overuse condition that has become a global problem for all ages who use smartphones. Although therapeutic approaches are used to manage text neck syndrome, relatively little evidence exists on efficacy. This study aimed to investigate the effects of proprioceptive neuromuscular facilitation (PNF) techniques on individuals with text neck syndrome. Thirty-eight participants with text neck syndrome were randomly allocated to either the experimental or control group. Both groups performed the program including cervical range of motion, strengthening, and posture correction exercises for 6 weeks, 3 days a week, once a day for 10 repetitions. In the experimental group were included in a PNF program 3 days a week for 6 weeks. In the program, contract-relax and replication techniques were used. Pain intensity, cervical range of motion, cervical muscles' endurance, posture, and disability were assessed. Outcome measures were assessed at baseline and after 6 weeks. Pain intensity, neck muscle endurance tests, posture, and disability scores significantly improved in both groups (P < .05). The cervical range of motion values in all directions were significantly increased only in the experimental group (P < .05). The improvements in pain intensity, neck muscle endurance tests, posture, and disability scores were greater in the experimental group compared with the control group (P < .05). PNF could be used effectively to reduce neck pain and disability level and enhance cervical range of motion, cervical muscles' endurance, and posture in individuals with text neck syndrome.

Evaluation of lumbar core stability among club level cricket bowlers: A cross-sectional study.

To evaluate the lumbar core stability in club-level cricket bowlers. This descriptive cross-sectional study was conducted in the twin cities of Rawalpindi and Islamabad in Pakistan from July 15 to December 10, 2022, after approval from the ethics review board Foundation University Medical College, Islamabad, and comprised male, club-level, hard-ball cricket bowlers aged 18-24 years. Data was collected through a self-structured demographic sheet, and core stability was assessed using McGill Torso Muscle Endurance Test Battery. Data was analysed using SPSS 21. There were 296 male subjects with a mean age of 20.1±1.77 years. Of them, 90(30.4%) bowlers had good lumbar flexion-to-extension ratio and 206(69.6%) had poor ratio. Lateral endurance test of right-to-left side-bridge ratio showed 71(24%) players in the good category, and 225(76%) in the poor category. The ratio of right lateral endurance to lumbar extensor was good in 55(18.6%) and poor in 241(81.4%) subjects. The ratio of left lateral endurance to lumbar extensor endurance was good in 40(13.5%) players and poor in 256(86.5%). Lumbar core stability was found to be quite poor among club-level cricket bowlers of Rawalpindi and Islamabad.

Effect of Inspiratory Muscle-Loaded Exercise Training on Ventilatory Response and Intercostal Muscle Deoxygenation During Incremental Cycling Exercise

ABSTRACT Purpose: This study evaluated the effects of exercise training (ET) and inspiratory muscle-loaded exercise training (IMLET) on ventilatory response and intercostal muscle deoxygenation levels during incremental cycling exercise. Methods: Twenty-one male participants were randomly divided into IMLET (n = 10) or ET (n = 11) groups. All participants underwent a 4-week cycling exercise training at 60% peak oxygen uptake. IMLET loaded 50% of maximal inspiratory pressure (PImax). Respiratory muscle strength test, respiratory muscle endurance test (RMET), resting hypoxic ventilatory responsiveness (HVR) test, and incremental cycling test were performed pre- and post-training. Results: The extent of improvement in the PImax was significantly greater in the IMLET group (24%) than in the ET group (8%) (p = .018), and an extended RMET time was observed in the IMLET group (p < .001). Minute ventilation ( V ˙ E ) during exercise was unchanged in both groups before and after training, but tidal volume during exercise increased in the IMLET group. The increase in the exercise intensity threshold for muscle deoxygenation was similar in both groups (p < .001). HVR remained unchanged in both groups post-training. The exercise duration for the incremental exercise until reaching fatigue increased by 7.9% after ET and 6.9% after IMLET (p < .001). Conclusion: The 4-week IMLET improved respiratory muscle strength and endurance but did not alter HVR. Respiratory muscle deoxygenation was alleviated by exercise training, with a limited impact of inspiratory load training.

Comparison of Biomotor Fitness Variables between Basketball and Volleyball Players in Ignatius Ajuru University of Education

Background: The purpose of this study is to compare the biomotor fitness variables between basketball and volleyball players in Ignatius Ajuru University of Education. This study adopted an ex post facto research design. Methodology: The population for this were all volleyball and basketball players, from which a sample size of 10 participants from each team were selected. To test for balance, a stork stand test was carried out, vertical jump test was used to test for power, an Illinois Agility Test (IAT) was used to test for agility, a 30m sprint/dash was used to assess the speed of the participants, and timed push-up test for muscular endurance. Statistical Package for Social Sciences (SPSS) version 25 was used for data analysis. Results &amp; Discussion: The findings revealed a 0.13 percent difference in power which was no statistically significant difference (p&gt;.05, p=0.987). There was 30.8 percent in balance which was statistically significant (p&lt;05, p=0.037). A 1.4 percent difference in agility was not deemed statistically significant (p&gt;.05, p=0.827). Volleyball players' performed 13.1% better in muscle endurance test, though not considered statistically significant (p&gt;.05, p=0.142). Conclusion &amp; Recommendation: Based on the findings from the study, it was evident that biomotor fitness variables among volleyball and basketball players in Ignatius Ajuru University of Education was virtually the same as the players demonstrated no significant difference in most biomotor variables such as speed, agility, power and muscular endurance. While being a jack of all trade (sports) makes one better than a master of none, in sports there is need for proper focus on a specific sports niche. Thus, coaches and trainers of volleyball and basketball players should help both category of players concentrate their efforts on a specific sport so as to achieve maximum biomotor fitness required for maximal performance in a specific sport.

Disability reduction following a lumbar stabilization exercise program for low back pain: large vs. small improvement subgroup analyses of physical and psychological variables

BackgroundLittle is known about why patients with low back pain (LBP) respond differently to treatment, and more specifically, to a lumbar stabilization exercise program. As a first step toward answering this question, the present study evaluates how subgroups of patients who demonstrate large and small clinical improvements differ in terms of physical and psychological changes during treatment.MethodsParticipants (n = 110) performed the exercise program (clinical sessions and home exercises) over eight weeks, with 100 retained at six-month follow-up. Physical measures (lumbar segmental instability, motor control impairments, range of motion, trunk muscle endurance and physical performance tests) were collected twice (baseline, end of treatment), while psychological measures (fear-avoidance beliefs, pain catastrophizing, psychological distress, illness perceptions, outcome expectations) were collected at four time points (baseline, mid-treatment, end of treatment, follow-up). The participants were divided into three subgroups (large, moderate and small clinical improvements) based on the change of perceived disability scores. ANOVA for repeated measure compared well-contrasted subgroups (large vs. small improvement) at different times to test for SUBGROUP × TIME interactions.ResultsStatistically significant interactions were observed for several physical and psychological measures. In all these interactions, the large- and small-improvement subgroups were equivalent at baseline, but the large-improvement subgroup showed more improvements over time compared to the small-improvement subgroup. For psychological measures only (fear-avoidance beliefs, pain catastrophizing, illness perceptions), between-group differences reached moderate to strong effect sizes, at the end of treatment and follow-up.ConclusionsThe large-improvement subgroup showed more improvement than the small-improvement subgroup with regard to physical factors typically targeted by this specific exercise program as well as for psychological factors that are known to influence clinical outcomes.

Relationship between abnormal pelvic floor electromyography and obstetric factors in postpartum women: a cross-sectional study

ObjectiveTo evaluate the surface electromyography (sEMG) of pelvic floor muscles (PFMs), compare between vaginal birth and cesarean section and correlate with maternity and obstetrics characteristics in primiparous 6–8 weeks postpartum.MethodsPFMs surface electromyography screening data of primiparous postpartum women in our hospital at 6–8 weeks postpartum from 2018 to 2021 were selected and analyzed. The study collected data on delivery activities of 543 postpartum women totally.ResultsIn general, the abnormal incidence of pelvic floor electromyography in postpartum women mainly occurred in slow muscle (type I fiber) stage and endurance testing stage. Compared to vaginal birth postpartum women, the incidence of abnormal pelvic floor electromyography in cesarean section postpartum women is lower. There were statistical differences in measurement values of pelvic floor electromyography in several different stages between cesarean section and vaginal birth (P < 0.005). Regarding the influence on pelvic floor electromyography, there were more influencing factors on vaginal birth postpartum women including age, height, weight, weight gain during pregnancy, gestational week, and first and second stage of labor than on cesarean section postpartum women whose influencing factors included age, weight gain during pregnancy, and newborn weight.ConclusionEffects on surface electromyography (sEMG) of pelvic floor muscles (PFMs) at 6–8 weeks postpartum differed based on the different modes of delivery. The high-risk obstetric factors closely related to abnormal surface electromyography (sEMG) of pelvic floor muscles (PFMs) were maternal age, height, weight, and second stage of labor.

Effects of Acute Ingestion of Caffeine Capsules on Muscle Strength and Muscle Endurance: A Systematic Review and Meta-Analysis.

This study aimed to explore the effects of acute ingestion of caffeine capsules on muscle strength and muscle endurance. We searched the PubMed, Web of Science, Cochrane, Scopus, and EBSCO databases. Data were pooled using the weighted mean difference (WMD) and 95% confidence interval. Fourteen studies fulfilled the inclusion criteria. The acute ingestion of caffeine capsules significantly improved muscle strength (WMD, 7.09, p < 0.00001) and muscle endurance (WMD, 1.37; p < 0.00001), especially in males (muscle strength, WMD, 7.59, p < 0.00001; muscle endurance, WMD, 1.40, p < 0.00001). Subgroup analyses showed that ≥ 6 mg/kg body weight of caffeine (WMD, 6.35, p < 0.00001) and ingesting caffeine 45 min pre-exercise (WMD, 8.61, p < 0.00001) were more effective in improving muscle strength, with the acute ingestion of caffeine capsules having a greater effect on lower body muscle strength (WMD, 10.19, p < 0.00001). In addition, the acute ingestion of caffeine capsules had a greater effect in moderate-intensity muscle endurance tests (WMD, 1.76, p < 0.00001). An acute ingestion of caffeine capsules significantly improved muscle strength and muscle endurance in the upper body and lower body of males.

A Profile of Isometric Cervical Strength in Elite Professional Male Rugby Players.

OBJECTIVES: To (1) provide position-specific normative data for isometric cervical muscle strength and endurance in professional, male rugby players and (2) assess the relationship between age, height, weight, and playing position with cervical muscle strength and endurance. DESIGN: Cross-sectional study. METHODS: Professional rugby players completed peak isometric cervical strength testing followed by a test of cervical muscle endurance. Descriptive statistics for continuous variables with strength normalized to body weight were performed. Multiple linear regression was used to estimate associations between strength measurements. RESULTS: In total, 136 players participated including front-row forwards (27%), other forwards (28%), and backs (45%). Front-row forwards had significantly greater peak isometric cervical muscle strength than other position groups, with backs having the lowest strength. Extension produced the highest force for all 3 position groups (429 N ± 104 N), whereas flexion produced the least (275 N ± 65 N). Age was associated with increased isometric cervical muscle strength. There was a statistically significant relationship between peak flexion strength and flexion endurance (P = .003). The average time for the endurance tests were 55.7 (±17.1) seconds and 52.9 (±20.1) seconds for extension and flexion, respectively. Other forwards had lower cervical extension muscle endurance than backs and front-row forwards. CONCLUSIONS: Normative values for peak and endurance isometric strength in professional rugby players illustrate significant differences between playing position. Consider age, body weight, and intraindividual variability when interpreting cervical strength and endurance results. J Orthop Sports Phys Ther 2024;54(3):1-8. Epub 29 January 2024. doi:10.2519/jospt.2024.11830.

Relationship Between Temporomandibular Joint Disorder Level and Clinical Parameters in Patients with Fibromyalgia Syndrome

Relationship Between Temporomandibular Joint Disorder Level and Clinical Parameters in Patients with Fibromyalgia Syndrome

Are trunk stability and endurance determinant factors for whole-body dynamic balance in physically active young males? A multidimensional analysis.

Determine if (a) a better trunk stability and endurance are associated with an improved whole-body dynamic balance, and if (b) the assessment tests can be interchanged within each capability. Sixty-three physically active young males performed three trunk stability (i.e., the lumbopelvic stability, the unstable sitting and the sudden loading sitting tests), three trunk muscle endurance (i.e., the Biering-Sørensen, the side bridge and the front bridge tests) and four whole-body dynamic balance (i.e., the tandem and the single-leg stance, the Y-Balance, and the single-leg triple hop tests) tests two times. After assessing the reliability of the variables, a Pearson correlation analysis was performed. The correlations between trunk stability and endurance tests with dynamic balance tests were non-significant except for the unstable sitting test with both the tandem (r = 0.502) and the single-leg stance (r = 0.522) tests. Moreover, no relationships were observed between the trunk stability and the trunk muscle endurance tests. Interestingly, no relationships were found between most tests within each capability (i.e., trunk stability, trunk endurance, and dynamic balance) except: (i) the front bridge stability test and the back (r = 0.461) and the side (r = 0.499) bridge stability tests; (ii) the two side bridge endurance tests (r = 0.786); (iii) the tandem and the single-leg stance tests (0.439 ≤ r ≤ 0.463); (iv) the Y-Balance and the single-leg triple hop tests (0.446 ≤ r ≤ 0.477). Better trunk function does not seem to be a relevant factor for dynamic balance in young active males. In this population, specific measures are needed as the test interchangeability is questioned.

The Improvement of Trunk Muscle Endurance in Adolescents with Idiopathic Scoliosis Treated with ScoliBrace® and the ScoliBalance® Exercise Approach

The impact of scoliosis bracing combined with physiotherapeutic scoliosis-specific exercises (PSSE) on trunk muscle endurance in adolescents with idiopathic scoliosis is unknown. ScoliBrace®, a rigid, three-dimensional, over-corrective thoraco-lumbar-sacral orthosis (TLSO), and ScoliBalance®, a PSSE program, were used to treat adolescent idiopathic scoliosis (AIS) patients. A retrospective study of the trunk muscle endurance of 33 AIS patients who received ScoliBrace® and ScoliBalance® was conducted. The patients were treated with ScoliBrace® and an individualized ScoliBalance® program. Trunk extensor muscle endurance (TE) and abdominal muscle endurance (AE) tests were performed at initial assessment and then at averages of 6.6 and 24.4 weeks of treatment. The data were analyzed using the Wilcoxon signed-rank test, Stata version 15.1. The participants were aged 13.24 years (SD = 1.64) with a mean Cobb angle of 38.97° (SD = 9.49°). TE improved significantly (p &lt; 0.001) at both short- and medium-term intervals using ScoliBalance® and ScoliBrace® in the AIS patients. AE also showed significant improvement between baseline and short-term follow-up, with non-significant improvement at medium-term follow-up. Overall, trunk muscle endurance showed improvement in the AIS patients using ScoliBrace® and ScoliBalance®. Future research is required to determine the individual and combined effects of each treatment. However, it seems likely that trunk muscle endurance will not deteriorate in AIS patients with this combined treatment.

Effects of Delayed-Onset Muscle Pain on Respiratory Muscle Function.

Delayed-onset muscle soreness (DOMS) has been widely examined in the peripheral muscles; however, studies showing the potential effects of DOMS on respiratory function are limited. DOMS in trunk muscles has a negative effect on respiratory function parameters, respiratory muscle strength, respiratory muscle endurance, and exercise capacity. Prospective cohort study. Level 2. In 24 healthy participants with a mean age of 21 ± 2 years, DOMS was induced for the trunk muscles with a load equal to 80% of the maximum repetitive voluntary contraction. Pulmonary function parameters, respiratory muscle strength and endurance, exercise capacity, pain, fatigue, and dyspnea perception severity were recorded before DOMS and at 24 and 48 hours after DOMS. After DOMS, decreases were observed in respiratory function parameters, namely, forced vital capacity, forced expiratory volume in the first second, vital capacity, and 25% to 75% flow rate value of forced expiratory volume (25% to 75%) (P = 0.02, P = 0.02, P < 0.01, P = 0.01, respectively). Maximal inspiratory pressure and exercise capacity also decreased (P = 0.02, P < 0.01, respectively). No difference was observed between all 3 measurements of maximal expiratory pressure (MEP) and MEP% values (P1 = P2 = P3 ≥ 0.99). The results of the respiratory muscle endurance tests did not reveal a significant difference in terms of load and time in all 3 conditions (P > 0.05). After DOMS, there was a 4% to 7.5% decrease in respiratory function parameters, and a 6.6% decrease in respiratory muscle strength. The occurrence of DOMS before a competition can have a detrimental impact on pulmonary performance. Hence, it is imperative to consider this factor when devising training and exercise programs. In addition, the development of treatment protocols becomes crucial if DOMS arises.

Effects of exercise therapy using elastic bands on strength and pain in women with non-specific neck pain: A randomised controlled trial

BackgroundCervical pain has a high incidence and worldwide socio-economic effect. Its incidence is lower in men than in women. Conservative and non-pharmacological therapeutic options include strength training. Elastic bands are commonly used in physiotherapy clinics for strength work in patients. Consequently, the objective of this research was to analyse the efficacy of an exercise therapy programme using elastic bands on decreasing pain and increasing strength of the neck flexor musculature, cervical extensor, and scapular stabilizing musculature in women suffering from non-specific cervical pain. MethodsA randomised clinical trial was carried out with 35 subjects with non-specific neck pain (age = 51.7 ± 9.5 and baseline intensity of pain in Visual Analogue Scale = 52.4 ± 9.6). The experimental group (n = 18) performed the exercise programme with elastic bands, consisting of a total of 16 sessions that lasted 45 min. The control group, consisting of 27 participants, reported that they maintained their usual lifestyle throughout the study. The evaluation tools used in this research included the Visual Analogue Scale, Neck Flexor Endurance Test, Neck Extensor Muscle Endurance Test, and Scapular Muscle Endurance Test. ResultsThe experimental group obtained significant improvements in the measurements taken using the Visual Analogue Scale (p < 0.001, d = 4.2), the Neck Flexor Endurance Test (p < 0.001, d = 3.4), the Neck Extensor Endurance Test (p < 0.001, d = 6.3), in the Scapular Muscle Endurance Test (p = 0.016, d = 0.9). ConclusionsThe assessed exercise therapy program utilizing elastic bands demonstrated favorable outcomes in managing non-specific neck discomfort. This intervention resulted in pain reduction and enhanced endurance of the cervical flexor and extensor muscles, along with improved endurance of the scapular stabilizing muscles.Protocol registration in ClinicalTrials.gov: NCT05433649 (registered prospectively, date of registration: June 27, 2022).

Poor cardiorespiratory fitness in first year medical students at a South African University

ABSTRACT The personal health behaviours, including physical activity, of healthcare professionals influence their counselling practices as they relate to non-communicable diseases (NCDs). However, despite the importance of producing healthy, physically active graduates, there are limited data on the physical fitness of future healthcare professionals. This cross-sectional observational study determined the prevalence of below-average fitness in the four components of fitness in first-year university medical students. 152 participants (46 male, 106 female, 20.16 ± 2.69 years) completed cardiorespiratory fitness tests (submaximal step test), flexibility (sit-and-reach test), muscle strength (handgrip), and muscle endurance tests (sit-ups, push-ups). Sex differences were reported using one-way ANOVA or Chi square test and significance was set at p < 0.05. The prevalence (%) of below-average fitness was 69.54% for cardiorespiratory, 25.66% for handgrip strength, 65.79% for sit-ups, 23.03% for push-ups and 7.24% for flexibility. Physical fitness parameters (mean±standard deviation (SD)) were compared between sexes, where it was found that females were more flexible than males (40.61 ± 8.40 cm vs 36.70 ± 9.31 cm, p = 0.012). Males had better handgrip strength (88.96 ± 12.04 kg vs 59.34 ± 10.36 kg, p < 0.001), muscle endurance sit-ups (33.46 ± 9.04 vs 24.48 ± 12.18, p < 0.001) and push-ups (30.28 ± 13.95 vs 24.27 ± 12.35, p = 0.009). First-year medical students have poor physical fitness, notably cardiorespiratory fitness and muscle strength, which are important markers for NCD risk assessment. Tertiary institutions training healthcare professionals should consider developing interventions to improve students’ physical fitness thereby influencing their health, wellbeing, academic performance and future counselling practices.
