Abstract

Adolescents today experience a decline in fitness, even though fitness is related to health. To improve fitness, there are many choices of sports or simple exercises that can be done, including jumping rope and brisk walking. These two exercises will be compared to find out which exercise is better in increasing cardiorespiratory endurance in adolescents. This study was an experimental study with a randomized control trial design on a total of 51 subjects divided into three groups, namely the jumping rope group (15 subjects), the brisk walking group (17 subjects) and the control group (19 subjects). The jump rope exercise was performed for 15 minutes, twice a day, while the brisk walking exercise was performed for 30 minutes. Both were carried out for 12 times, while the control group was not given any treatment. The results of the statistical analysis of the pre-test and post-test using Wilcoxon showed a value of p=0.050 in the jumping rope group, p=0.001 in the brisk walking group, and p=0.080 in the control group, while the post-test using Mann Whitney between the jumping rope and brisk walking shows the value of p=0.766. Jump rope and brisk walking can both increase cardiorespiratory endurance, but neither is better.

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.
