Abstract

Background of study: In sports, explosive lower-body power is often the difference between good and great performance, especially in movements like jumping. This study explored how body composition, specifically muscle and fat mass, relates to countermovement jump (CMJ) performance in 60 trained Indian collegiate athletes from various sports backgrounds. Methods: Using a bioelectrical impedance analyzer, we measured skeletal muscle mass (SMM) and fat mass (FM), while jump metrics like height, peak force, and peak power were captured using a high-frequency force platform. Result: Our results showed a strong positive link between muscle mass and both peak power (r = 0.792) and force (r = 0.741), and a moderate connection with jump height (r = 0.469). In contrast, fat mass was slightly but negatively related to jump height (r = -0.248) and flight time (r = -0.256), suggesting that excess fat might hold athletes back in movements requiring quick, explosive effort. Conclusion: These findings reinforce what many coaches and athletes observe in practice: more muscle, particularly in the lower body, usually means better jump performance, while unnecessary fat can be a limiting factor. The study highlights the importance of looking beyond total body weight and focusing on the quality of mass an athlete carries.

Abstract

Background: Futsal is a high-intensity sport that requires optimal lung capacity and aerobic endurance, efforts to improve VO₂max are often associated with nutritional interventions, including supplementation. Calcium D Redoxon (CDR), which contains vitamin C, vitamin D, and calcium, energy metabolism, and the immune system. This study aims to investigate the effect of Calcium D Redoxon supplementation after exercise on the improvement of VO₂max in futsal athlete. Methods: The research method eksperimen used a design one-group pretest-posttest design with a total sampling technique involving 21 athletes. The instrument for measuring VO₂max endurance was a respirometer (FEV1), and data analysis included normality tests and a t-test. Result: The normality test results showed that variable X had an Asymp. Sig. (2-tailed) value of 0.103 (p > 0.05) and variable Y had an Asymp. Sig. (2-tailed) value of 0.148 (p > 0.05), indicating that both datasets were normally distributed. Based on the t-test results, the pretest mean was 4492.952 ml with a t-value of 43.418 and a significance value of 0.000 (p < 0.05), indicating statistical significance. The posttest mean was 4088.857 ml with a t-value of 42.525 and a significance value of 0.000, also indicating high statistical significance. Although both results are statistically significant, there was an average decrease of 404.095 ml from pretest to posttest. Conclusion: These findings indicate that the intervention did not positively impact lung capacity improvement; in fact, it tended to cause a decrease.

Abstract

Background of Study: Smoking has long been recognized as a risk factor for impaired cardiovascular and respiratory functions, yet its specific effects on athletic performance require further clarity. For athletes, maintaining high aerobic capacity and efficient recovery is essential for endurance, training adaptation, and competitive success. This study aimed to compare maximal oxygen and post-exercise recovery dynamics- VO2 Max, Heart Rate Recovery, Oxygen Saturation, and Breathing Frequency between smoking and non-smoking athletes.. Methods: A comparative cross-sectional design was employed with forty trained athletes aged 25–28 years, equally divided into smoking and non-smoking groups, each with at least four years of competitive training. Participants performed a graded treadmill exercise test followed by standardized recovery assessments under controlled laboratory conditions. Result: Findings revealed that non-smoking athletes achieved significantly higher maximal oxygen uptake, reflecting superior aerobic capacity. While differences in oxygen saturation, heart rate recovery, and breathing frequency were not statistically significant, smokers showed trends toward lower oxygen availability, slower cardiovascular recovery, and less efficient ventilatory adjustment. Conclusion: In conclusion, maximal oxygen uptake emerged as the most sensitive marker distinguishing smokers from non-smokers, underscoring the detrimental influence of tobacco use on endurance and recovery. These results emphasize the importance of discouraging smoking among athletes to safeguard physiological efficiency, support optimal training, & enhance long-term performance.

Abstract

Background of study: Lack of physical exercise has significant influence on the rise of cases of non-communicable diseases (NCDs) among university students globally. University students` engagement in physical excercises tend to decline when compared to previous school years. The decline is also observed in Eswatini`s university students. This study, therefore, described the facilitators and barriers of engaging in physical exercises by tertiary students of one Campus of the University of Eswatini. Methods: A descriptive qualitative research design was employed to describe the facilitators and barriers of physical exercise of ten purposively sampled students. Data was collected through audio-recorded face-to-face interviews utilising a researcher developed interview guide. Data were analysed using thematic analysis of Colaizzi’s descriptive method of data analysis. Result: Four themes emerged from the study findings; 1) Students understanding of physical exercise, 2) Facilitators of physical exercise, 3) Barriers of physical excercise, 4) Strategies to improve physical exercise engagement. Conclusion: Students` physical exercise participation is characterised by facilitators and barriers. Therefore, students need practical support from the university in terms of provision of enough variety of training facilities and equipment within the campus, and time alocated for physical activities within the course of their learning.

Abstract

Background: Badminton officials play a crucial role in ensuring fair play and accurate decision-making during competitions. However, officiating tasks are performed under high cognitive demands, time pressure, and social stressors, which can influence physiological responses and cognitive performance. Empirical evidence examining stress dynamics in badminton officials using objective physiological indicators remains limited. Methods: This study employed a descriptive repeated-measures design involving 102 certified badminton officials during a national-level competition. Heart rate data were recorded across five conditions: early morning rest, sitting near the referee table, during game intervals, between matches, and after competition. Data were analyzed using descriptive statistics, repeated-measures ANOVA, and Bonferroni post-hoc tests to identify differences in physiological responses across officiating situations. Result: Heart rate values increased progressively from resting conditions to peak levels during game intervals and between matches, indicating heightened physiological stress, before decreasing after the competition. Significant differences were observed across all measurement conditions (p < .001). Key stressors included spectator noise, high cognitive load, time pressure, and interpersonal and organizational demands. Elevated arousal levels suggested delayed physiological recovery during continuous officiating duties. Conclusion: Badminton officiating is associated with substantial physiological stress, particularly during critical match phases. Sustained stress may negatively affect cognitive and emotional functioning. The findings highlight the importance of implementing effective coping strategies, such as controlled breathing, mindfulness, and structured recovery routines, to support officials’ performance, well-being, and long-term officiating capacity.

Abstract

Background: A key indicator of an individual's capability to generate explosive strength, the effectiveness of their neuromuscular coordination, and their stamina is assessed through the vertical jump test. Sports science research commonly uses surface electromyography (sEMG), a non-invasive technique for measuring muscles' electrical activity. In this study, we utilized electrical signal magnitude-based measurements to analyze the electrical activity of the Rectus Femoris, Gluteus Maximus, Gastrocnemius Medialis, and Biceps Femoris Caput Longus muscles in the thigh and calf during vertical jumps. Methods: The study involved seventeen male athletes as participants. The FREEEMG system captured EMG signals at a sampling rate of 1000 Hz, and using MATLAB, the parameters RMS, MAV, MAD, and WAMP were computed. Result: According to the findings, the Rectus Femoris and Gluteus Maximus muscles are crucial for producing explosive power in the propulsion phase, and their amplitude characteristics remained fairly consistent across multiple jumps. Conversely, the Gastrocnemius Medialis and Biceps Femoris muscles showed a steady decline in amplitude, which indicated the start of fatigue. Conclusion: In conclusion, the thigh muscles were primarily responsible for generating force, whereas the calf muscles mainly aided in maintaining postural stability and the last stage of propulsion.
