Brief Summary

Resistance training (RT) is one of the most important stimuli for muscle hypertrophy and it plays an important role on weight loss and fatty acid oxidation increase. RT affects anabolic pathways but the differences among various training techniques has been till now were poorly investigated. The aim of this study was to compare the effect of two different intensity of training, high-intensity interval resistance training (HIIRT) and traditional resistance training (TRT), on muscle signalling pathway.

Study Arms (2)

High Intensity Interval Resistance Training (HIIRT)

EXPERIMENTAL

HIIRT technique consisted of three sets of: 6 repetitions at 80% 1RM (1 repetition maximum) and then 20 seconds of rest and 2/3 repetitions (until exhaustion) repeated for 3 times with 2'30" rest between sets; while TRT consisted of 3 sets of 15 reps with 75 sec of rest between sets.

Other: High Intensity Interval Resistance Training

Traditional Resistance Training (TRT)

ACTIVE COMPARATOR

TRT protocol performed 3 series of 15 repetitions at 60% 1RM with 75" of rest between sets.

Other: Traditional Resistance Training

Interventions

Subjects trained one leg with HIIRT

High Intensity Interval Resistance Training (HIIRT)

Subjects trained the other leg with HIIRT
