Abstract

Good physical performance must also prioritize metabolic health. Metabolic health is influenced by body composition, including muscle mass and visceral fat. Muscle mass plays a role in the performance and quality of body metabolism, while visceral fat around the liver, pancreas, and intestines is an indicator of metabolic health that affects insulin resistance, chronic inflammation, and metabolic diseases. Good training is needed to find the right recipe for maximizing muscle mass and controlling visceral fat levels. This study aims to compare muscle mass and visceral fat in female aquatic athletes to see health parameters without neglecting performance. This study used a cross-sectional design involving 15 subjects from female swimming and diving athletes from the KONI Malang City pool. Measurement of muscle mass and visceral fat used a BIA (Bioelectrical Impedance Analysis) tool. Correlation analysis was used to determine the relationship between muscle mass and visceral fat. The results showed that all research subjects had low muscle mass with a maximum value of 21.03 and visceral fat in the high category of 0.67. Low muscle mass is likely caused by suboptimal training outcomes or by strength training not maximizing muscle mass composition, while high visceral fat can be influenced by poor nutritional management by athletes. Physical performance and metabolic health are crucial, especially in optimizing muscle mass and minimizing visceral fat. Low muscle mass is caused by inadequate training methods, particularly strength training, including a lack of attention to training principles such as intensity, frequency, and loading.

Abstract

The study aims to determine the timing of ice compression on the onset of DOMS after submaximal exercise. This research is experimental with post-test only control group design. Thirty students of the Faculty of Medicine, Sebelas Maret University participated as subjects. Subjects were divided into three groups, control, treatment 1 hour after exercise, and 4 hours after. Submaximal exercise is done by step test. Ice compression was given for 10 minutes on subject’s front thigh muscles. DOMS pain was assessed using the VAS pain scale. The collected data were analyzed using the one way Anova test and continued with the Post Hoc LSD test. The results of the analysis using the one way Anova test showed a significant difference between the three research groups and the Post Hoc test showed no significant difference between two treatment groups, but the treatment 4 hours group had lower pain scale on VAS. Ice compression after 4 hours exercise can inhibit the macrophages which were the main immune cells for inflammatory reactions. From this study, it was concluded that the most effective timing of ice compression on the onset of DOMS was 4 hours after submaximal exercise.

Abstract

Muscle overuse during exercise increases the risk of muscle injury. L-citrulline, one of the ergogenic substances highly found in watermelon, is frequently used to reduce muscle soreness. This study aimed to compare the effects of pure L-citrulline and watermelon juice in reducing delayed-onset muscle soreness (DOMS) and muscle damage using uric acid as a marker for inflammation. A single-blind controlled trial was employed among 33 participants selected with a purposive sampling method. The participants were given either a mineral water drink containing 1.2 g of L-citrulline supplementation, 750 ml of watermelon juice, or a bottle of mineral water as a placebo administered 2-h before exercise. A multiple-sprint with a deceleration phase was used to induce DOMS. There was a significant decrease of DOMS 12 h and 24 h post-exercise with watermelon juice and pure L-citrulline (p=0.001). However, there was no significant difference in effectiveness between both forms of supplementation (p = 0.748). There were no significant changes in uric acid levels post-exercise with both forms of supplementation. Both watermelon juice and pure L-citrulline show similar effectiveness in improving subjective feelings of DOMS but fail to provide evidence of their ability to reduce muscle inflammation significantly via the reduction of uric acid levels.

Abstract

Background: Asthma control level is related to body composition. Somatotype is a body shape classification that is used to measure body composition indirectly using anthropometry. As far as we know, no studies are related to somatotype and asthma control levels. This study aims to describe the somatotype and the ratio of chest circumference to height and its relation to asthma control level. Methods: This research is an observational study at Surakarta in September-December 2022. The subjects were 51 asthma patients under control and met the criteria. Measurement of somatotype and the ratio of chest circumference to height was carried out by anthropometric methods. The Asthma Control Test (ACT) questionnaire assessed the asthma control level. The collected data were analyzed using SPSS 26 software with Fisher’s test and unpaired t-test. Results: out of 51 asthmatic patients, 43 (84,3%) had endomorphic and 8 (15,7%) ectomorphic. Fisher’s test showed no significant relationship between somatotype and asthma control level (P=0.56). Meanwhile, the mean ratio of chest circumference to height in controlled patients was 0.54, while those who were uncontrolled were 0.58. The results of the unpaired t-test showed that there was a significant difference between the ratio of chest circumference to height and asthma control level (P=0.03).   Conclusion: There is no significant relationship between somatotype and asthma control level, but there is a significant relationship between the ratio of chest circumference to height and the asthma control level.

Abstract

This study aims to determine the extent of the effect of L-Arginine amino acid supplementation on oxygen saturation and lactic acid levels at the fitness level (VO2Max) of West Kalimantan muaythai athletes. High lactic acid levels can be an indicator of fatigue in athletes after undergoing a physical fitness test. This type of quantitative descriptive research used a randomized group pretest-posttest group design sampling method. The subjects in the study used were male athletes on the West Kalimantan Muaythai team who will be prepared for the 2024 International Student Muaythai Championship. In this study, the subjects were divided into two groups, the first group was given a placebo and the second group was given the amino acid L-arginine. Each group was given the same treatment, namely a physical fitness test to determine the VO2Max level using a bleep test. Before and after carrying out the physical fitness test, the subjects were checked for oxygen saturation, and blood lactic acid samples were taken. The results showed that L-Arginine supplementation had a positive effect in helping to maintain optimal oxygen saturation in the body and reducing the accumulation of blood lactic acid levels that can cause fatigue in Muay Thai athletes. This shows the significant role of L-arginine supplementation in helping to enhance physical endurance performance and speed up recovery during and after physical activity.

Abstract

Highlights: 1. This study emphasizes the significance of understanding professional football players' various somatotype structures and body fat compositions as an important contribution to the area of sports science. This study lays the groundwork for future research to better understand the intricate interactions between somatotype structures, body composition, and athletic performance. 2. Since a one-size-fits-all approach may not be successful, this study advocates for tailored evaluations of training regimens to cater to athletes' unique requirements and skills, which may lead to higher overall performance. Abstract This study investigated the effects of somatotype structures and body fat composition on professional football athletes' aerobic capacities and running speed. This study used an analytical observational design with a cross-sectional approach. The subjects comprised 27 professional football athletes from Bhayangkara Football Club, located in Bekasi, Indonesia. This study measured several variables, i.e., players' age, playing position, somatotype structures assessed using the Somatotype Rating Form and Heath-Carter Somatochart, body fat composition measured using Brozek and Siri formulas, aerobic capacities determined by the maximum rate of oxygen (VO2 max) through the Yo-Yo Intermittent Recovery Test Level 2, and running speed over a 30 m distance. The data were presented as mean ± standard deviation (SD), frequency (n), and percentage. The Shapiro-Wilk was used to determine the normality of the data distribution. The statistical analyses were conducted using one-way analysis of variance (ANOVA) followed by the post-hoc least significant difference (LSD) test, the Kruskal-Wallis test followed by the post-hoc Mann-Whitney test, as well as the independent t-test, the Mann-Whitney test, and Pearson's or Spearman's correlation tests. A value of p<0.05 was considered statistically significant. The athletes exhibited a predominant somatotype structure of mesomorph-endomorph (88.9%). Notable associations were found between mesomorphy rating and running speed (r=-0.548; p=0.003), body fat composition and aerobic capacity (r=-0.448; p=0.019), as well as age and aerobic capacity (r=-0.515; p=0.006). Notably, differences in aerobic capacity were observed among various age groups (p=0.031). There were also differences in body fat composition (p=0.003) and running speed (p=0.036) between two distinct somatotype structures. These findings underscore the importance of considering individualized training and conditioning programs that account for athletes' unique body compositions and ages.

Abstract

Highlights: 1. This study elucidates the effect of L-citrulline supplementation on creatine kinase MM (CK-MM) expression post-eccentric exercise, offering novel insights into its potential role in mitigating muscle damage. 2. The findings demonstrate that L-citrulline administration significantly reduces CK-MM expression levels in skeletal muscle tissue, suggesting its therapeutic potential in enhancing muscle recovery and performance following exercise-induced damage. 3. This study contributes valuable insights into the multifaceted benefits of L-citrulline supplementation for supporting overall muscle health and performance by identifying its protective effects under different mechanisms, including improved blood flow, antioxidant activity, enhanced mitochondrial function, and promotion of muscle protein synthesis.   Abstract Eccentric exercise often induces muscle injuries in athletes, resulting in impaired performance and prolonged recovery time. Creatine kinase MM (CK-MM) is a biomarker for assessing muscle damage, with elevated levels indicating injury. L-citrulline, an amino acid, has shown promise in enhancing performance and reducing recovery time. However, its specific effect on CK-MM remains unclear. This study utilized immunohistochemistry analysis to investigate the effect of L-citrulline supplementation on CK-MM expression post-eccentric exercise in male BALB/c mice. This in vivo study was conducted with a post-test-only design. A total of 25 mice were divided into two control groups (normal/C1 and negative/C2) and three treatment groups (T1, T2, and T3), each containing five mice. The T1, T2, and T3 groups were daily administered 250, 500, and 1,000 mg/kg bw of L-citrulline for seven days, respectively. All mice, except the C1 group, performed a downhill running procedure. The CK-MM expression in skeletal muscle tissue post-eccentric exercise was assessed using immunohistochemistry analysis. The statistical analysis included the Shapiro-Wilk test for data distribution and the Kruskal-Wallis and Mann-Whitney post-hoc tests for significant differences (p<0.05). The results showed that CK-MM expression in the C2 group (91.00±2.24%) was significantly higher (p=0.008) than that of the C1 group (70.00±10.0%). Subsequently, the T1 (68.00±9.08%, p=0.008), T2 (72.00±7.58%, p=0.008), and T3 (67.00±9.75%, p=0.008) groups exhibited significantly lower expressions than the C2 group. These results were consistent with the role of CK-MM as a marker for muscle damage, and they indicated that L-citrulline might have a protective effect against muscle damage post-eccentric exercise. However, no significant differences were observed among the C1, T1, T2, and T3 groups. In conclusion, L-citrulline supplementation demonstrates promise in attenuating muscle damage following eccentric exercise, as evidenced by reduced CK-MM expression levels. These findings highlight the potential therapeutic role of L-citrulline in enhancing muscle recovery and performance.
