Effect of Green Tea Extract in Conjunction with Exercise Training on Anaerobic Performance of College Students

Abstract

This study aimed to evaluate the effects of various interventions on anaerobic power, fatigue index, and overall performance in college students. Participants were 30 college students aged 18-22 years from Sichuan Vocational College of Health. Their height, weight, and anaerobic capacity were measured using the Running-based Anaerobic Sprint Test (RAST). Based on their RAST test scores, the students were divided into three groups of 10 participants each (3 boys and 7 girls). Group 1 received a placebo (500mg) combined with 4 weeks of athletic training, Group 2 received a single dose of 500mg green tea extract with exercise, and Group 3 received 500mg green tea extract combined with 4 weeks of athletic training. Pre- and post-experiment data were analyzed using paired T-tests, while differences between groups were assessed using one-way ANOVA with a significance level of P < 0.05. Results from the paired T-test showed no significant changes in anaerobic capacity for Group 1, while Group 2 displayed significant improvements in anaerobic capacity and mean power among girls (P < 0.05). Group 3 demonstrated significant enhancements in anaerobic power, fatigue index, and mean power for both boys and girls (P < 0.05). One-way ANOVA revealed significant differences in anaerobic power, average power, and fatigue index across the groups, with Group 3 showing the most notable improvements. The findings suggest that combining green tea extract with prolonged athletic training significantly improves anaerobic capacity, particularly in female participants. These results highlight the potential benefits of green tea extract in enhancing athletic performance, warranting further research to explore its long-term effects and the optimization of exercise interventions.
