Abstract
Purpose:
Soccer is one of the most popular and well-known sports in the world. Better performance in this sport requires high physical fitness. Therefore, the aim of this study was to investigate the effect of total body resistance training and plyometrics on physiological indicators of young male soccer players.
Methods:
The present study was a quasi-experimental study with a pre-test-post-test design. The statistical sample of the study included 30 young male soccer players with an age range of 18 to 30 years. A Polar heart rate sensor, a Lactometer device, and a mercury sphygmomanometer were used to measure maximum oxygen consumption. Plyometric and TRX exercises were performed for eight weeks by both groups. The research variables were measured before the intervention and after a maximum of 48 hours after the exercises. Data analysis was performed using SPSS software version 24. Covariance test was used to compare results between groups and paired t-test was used to compare results within groups at a significance level of 0.05.
Results:
The between-group results showed that the variables VO2max (p=0.010) and systolic and diastolic blood pressure (p=0.001) had significant differences between the groups. Also, the variables lactate and VO2max (p-0.001) had a significant increase in the post-test compared to the pre-test, which was greater in the plyometric training group. Systolic blood pressure (p=0.001) had a significant decrease in the plyometric training and total body resistance training (TRX) groups in the post-test compared to the pre-test. Also, diastolic blood pressure (p=0.008) had a significant decrease in the TRX training group, while no significant difference was observed in the plyometric training group in the pre-test and post-test for diastolic blood pressure.
Conclusion:
Plyometric and TRX training improve physiological indicators in young soccer players. Plyometric training has a greater effect than TRX training in improving these indicators
