Concurrent Training on the Performance of Team Sports Athletes

Their training program included 4 resistance exercises with heavy weight lifting of the leg muscles. 3 sets of 6-8 repetitions of 80-90 % of maximal load were performed with a barbell squat (range of 0 to 90º knee flexion), lying leg curl, seated calf raises, and leg extension. The rests between the sets and the exercises lasted 5 minutes.

Their resistance training program contained the same exercises as the high resistance training group, but with different intensity. Athlete performed each exercise for the first time with 5-7 reps with 80 % of the 1RM load followed by 15-20 reps with 40 % of the maximal load to complete the 3 sets for each exercise. The rest period between series was 60 seconds and the rest period between exercises was 5 minutes. For example, 5 heavy barbell squats followed immediately by 20 squat with lighter weight to complete 3 sets.

During the intervention, the group conducted a 'elastic resistance training' with the same muscle groups. External resistance was provided by blue thera-band latex-free exercise bands in this training. Each exercise was performed three times for a total of 15-25 repetitions. In between sets, a 5-minute rest period was given and there was a 25-second rest period in between exercise performance. The intensity of each exercise was increased with the black thera band at the midpoint (start of week 7) of the training. The following figure shows the resistance of the blue and black bands to 100 percent elongation. Following figure shows the resistance offered by blue and black band at 100% elongation.
