The effects of blood flow restriction training (BFR) may be impacted by the several physiological and biological differences found between genders. Since the pattern of regional body composition may be different between males and females, the impact of tightness of the restrictive cuffs (initial restrictive pressure; IRP) might be different for females causing variation in the level of muscle activation; therefore research on a female population is needed to have a complete understanding of BFR. PURPOSE: To compare changes in electromyography (EMG) amplitude (RMS) and median frequency (MDF) in males and females during application of different IRPs of 40-45 mmHg …

Resistance training (RT) is recommended for elderly with the objective to increase muscle strength and power trough neuromuscular adaptations, inducing increased motor and functional capacities. The electromyography (EMG) is an important instrument to analyze muscle function after diverse exercise training protocols. The objective of the present study was to analyze electromyographic activity of vastus lateralis oblique muscle (VLO) during maximal voluntary isometric contraction of elderly women submitted to 12 weeks of periodized RT. 16 women aged 65.5±3.6 years with a minimum of one year of previous experience in strength training were selected, they performed 24 sessions of RT divided in …

Motor unit recruitment of individual muscles could substantially differ with changes in speed and load. However, the recruitment patterns associated with low intensity walk training with vascular restriction at sustained loads and constant speed could be different than normal walking. Vascular restricted (VR) walk training is an effective method for increasing muscular strength; however the changes in motor unit recruitment and firing frequency have not been investigated to understand the mechanisms underlying the neuromuscular adaptations. Purpose: The purpose of this study was to analyze differences in electrical activity of the vastus lateralis during VR and non vascular restricted (non-VR) walking …
