Aim: was to investigate the impact of plyometric training and beetroot extract supplementation on anaerobic power, nitric oxide (NO), blood lactate, and pH following high intensity anaerobic exercise in football players.
Methods: 40 elite football players from Tabriz in 2023 were voluntarily divided into four groups (n=10 each): plyometrics, beetroot extract, plyometrics combined with beetroot extract, and a control group receiving a placebo. Plyometric training was conducted over six weeks, with two sessions per week. Participants in the supplement groups received beetroot juice twice daily or a placebo equivalent to 1ml of beetroot juice per kilogram of body weight. Brachial vein blood samples were taken to measure blood lactate, pH, and NO using the ELISA method. The RAST test was utilized to measure anaerobic power indices (peak, minimum, and average power, as well as fatigue index). Data analysis was performed using analysis of variance for factorial time series and Bonferroni's post hoc test.
Results: The findings revealed that six weeks of plyometric training and beetroot extract supplementation led to decreased blood pH, fatigue index, and perceived pressure (p<0.05). Plyometric training also resulted in decreased blood lactate (p<0.05), while beetroot extract supplementation did not have a significant effect on blood lactate (p > 0.05). Additionally, the combination of six weeks of plyometric training with beetroot extract supplementation increased anaerobic capacity and blood NO (p < 0.05).
Conclusion: Plyometric training and beetroot extract supplementation maybe effectively enhance anaerobic power and physical performance in soccer players.
