| Introduction: One of the most common purposes of training science emphasizes on the function and adaptation for better performance of the athlete skills. Adaptation to strength & endurance training is generally different, and, at times, opposed to each other. The purpose of this research was to investigate the neuromuscular adaptation of two types of training concurrently.
Materials & Methods: Thirty- six healthy male students [mean (so) age (21.6 ± 0.09) years, height (175 ± 3.39) cm, weight (73.6 ± 6.3) kg were randomly divided into three groups: the Strength group (n= 12), the Endurance group (n=12) and the Concurrent group (n=12).The strength group performed (%70-%85 1R.m) in 3 sets with 12, 10, 8 numbers respectively. The endurance group performed cycle interval training in 80- 90% maximum heart rate in 3 minutes the concurrent training included half strength and half endurance training with change of consequence of training 3 sections during 12 weeks. Surface electromyography (sEMG), Maximal Voluntary Contraction (MVC) Maximal Repetition (1RM) assessments were made before-middle and after training. General- leaner- model was used within the group and one- way ANOVA between the groups.
Findings: The final results of our study were as follows: the result within the group showed a significant decrease in all the groups, of mean signal (EMG) after 6 weeks and in (S) and (C) groups after 12 weeks. In all the groups, 1RM increased after 6, 12 weeks. MVC increased in (S) and (C) groups after 6, 12 weeks, but in (E) group, it did not increase significantly. The results among the groups, showed a decrease in the mean signal (EMG) and an increase in1RM with the same rate in (S) and(C) groups in 6, 12 weeks, but in (E) group, it wasn’t significant. In all the groups, MVC wasn’t significant in 6 weeks, but there was a significant difference in (S) and(C) groups in 12 weeks.
Discussion & Conclusion: The findings showed that the increasing strength of the concurrent group was less than that of the strength group and more than the endurance group. Probably, simultaneous exercise improves neuro-muscular adaptations without any disturbances in strengthening |
