Summary

The aim of the study is to investigate the effects of incorporating variability within a single session of Resistance Training (RT) methods on the neural adaptations along the corticospinal tract and on neuromuscular function. The literature suggests that RTis one of the most common modalities to enhance and restore muscle function and its practice results in adaptation in neural and morphological adaptations. Moreover, it is also known that muscle contraction relies on the coordination and regulation of the descending neural drive from the motor cortex to the motoneurons and from the motoneurons to the muscles. However, traditional RT programs tend not to address this motor control dimension. Recent approaches such as metronome paced strength training have been used to cover this motor control dimension through a greater control and consciousness of movement. However, this methodology tends not to incorporate the inherent variability and complex, fractal-like fluctuations that characterize human movement. The investigators propose that incorporating variability through a fractal-like metronome approach will speed up the neural adaptations which will be useful in injury rehab

Interventions

Type	Name	Description
OTHER	Fractal Paced	The intervention consists in a single session of metronome paced strength training composed by 4 sets of 15 repetitions at 65% of the one-repetition maximal (1RM) in single leg extension machine, synchronizing each repetition with fractal external cues presented by a visual metronome. The rest between sets will be set at 2 minutes of rest between sets.
OTHER	Isochronus Paced	The intervention consists in a single session of metronome paced strength training composed by 4 sets of 15 repetitions at 65% of the one-repetition maximal (1RM) in single leg extension machine, synchronizing each repetition with isochronus external cues presented by a visual metronome. The rest between sets will be set at 2 minutes of rest between sets.
OTHER	Self Paced	The intervention consists in a single session of strength training composed by 4 sets of 15 repetitions at 65% of the one-repetition maximal (1RM) in single leg extension machine, at at participants' own self pace (with no metronome). The rest between sets will be set at 2 minutes of rest between sets.
