Abstract
Purpose
The study aimed to determine and compare the effect of unilateral versus bilateral plyometric training on leg muscular performance in male beach soccer players.
Methods
Twenty-four male amateur beach soccer player, aged 18-35 years, were enrolled by purposive sampling and were randomly allocated to two groups (The first experimental group; unilateral plyometric training (UPT), n=12 and the second experimental group; bilateral plyometric training (BPT), n=12). Both experimental groups were trained twice a week for 6 weeks in addition to their usual training. Muscular power, reactive strength index, balance, agility, and 5-m and 10-m sprint time were measured before and after the intervention. The data obtained were analyzed within group using a Paired sample t-test, and for comparisons between groups using an Independent samples t-test. The statistical significance of all tests was set at P-value < 0.05.
Results
Following 6 weeks of training, both the UPT and BPT groups displayed similar improvements (p < 0.05) in peak power (both legs, dominant leg and non-dominant leg), balance, agility, and 5-m and 10-m sprint times. Moreover, only the UPT group showed significant improvement in peak barbell velocity for both the dominant and non-dominant legs. Additionally, the UPT group showed higher jump height in the non-dominant leg while the BPT group demonstrated improvements in both legs (p < 0.05). Furthermore, the BPT group showed significantly better peak ground reaction force in the non-dominant leg (p < 0.05) whereas the UPT group did not show these improvements. The UPT group exhibited greater peak power in the dominant leg, peak barbell velocity, and jump height in both the dominant and non-dominant legs compared to the BPT group (p < 0.05).
Conclusion
These findings indicate that both training styles are useful method for enhancing muscular power, balance, agility, and acceleration ability. However, we reccommeded a unilateral plyometric training program to improve unilateral leg muscular performance, while bilateral plyometric training should be selected to develop bilateral muscle performance.
