Abstract
Background
Currently, eccentric overload training a form of resistance training that emphasizes the lengthening phase of the muscle, thereby increasing force production during the subsequent shortening (concentric) phase has been found to improve muscle strength, muscle power, and muscle contraction velocity more effectively than traditional resistance training (Cook et al., 2013; Douglas et al., 2017). However, continuous eccentric overload training at high intensities leads to muscle fatigue. Consequently, implementing intra-set rest intervals allows the muscles to exert maximum force and mitigates the fatigue caused by eccentric overload training (Chae et al., 2024)
Purpose
The purpose of this study was to compare effects of combined accentuated eccentric loading training and rest redistribution on leg muscular performance in male soccer player.
Method
Twenty male soccer players, aged 18-25 years from Thailand National Sports University, Angthong campus participated in this study. Before the experiment, all subjects underwent a resistance training program at a load of 60% 1RM, twice a week for two weeks for familiarization. Thereafter, the participants were randomly assigned into 2 groups matched by 1RM relative back squat strength. The first experimental group (n=10), (AEL+RR), performed a combined accentuated eccentric loading training and rest redistribution program consisted of 10 repetitions at a load of eccentric/concentric was 110/60 % 1RM by accentuated eccentric loading in the 1st, 3rd, 5th, 7th and 9th combined with rest redistribution 15 seconds and 5 minutes rest between set with 3 sets in first and second week, 4 sets in third and fourth week and 5 sets in fifth and sixth week. The second was control group (n=10), (CON), continued their regular soccer training program. AEL+RR group continued to train twice a week for a total of 6 weeks. Peak power, peak ground reaction force, rate of force development, peak velocity, and relative strength were measured before and after 6 weeks of training. Data were expressed as means ± S.D. and were analyzed using independent sample t-test and paired sample t-test. The statistically significant was set at p-value < 0.05
Results
The results demonstrated that after 6 weeks of training, the AEL+RR presented significant increases in peak power, peak ground reaction force, rate of force development, peak velocity, and relative strength (p<0.05), while CON showed improvements in peak power, peak ground reaction force, rate of force development, peak velocity, and relative strength. Interestingly, The AEL+RR revealed greater improvement in peak power, peak ground reaction force, peak velocity, and relative strength compared to CON group.
Conclusion
Our results demonstrated that combined accentuated eccentric loading training and rest redistribution have favorable effects on peak power, peak ground reaction force, rate of force development, peak velocity, and relative strength, and could therefore be used as an adjunctive exercise program for improving leg muscular performance in male soccer player.
