Effect Of Resistance Training Combined With Neuromuscular Electrical Stimulation On Glycemic Control And Energy Metabolism In Overweight Adults, Seyram Y. Azagloh, Gabriel Narvaez, Zahra Fatahimeiabadi, Jehu Apaflo, Sudip Bajpeyi

International Journal of Exercise Science: Conference Proceedings

Obesity and insulin resistance are associated with impaired glycemic control and altered energy metabolism, increasing the risk for cardiometabolic disease. Resistance training (RT) improves body composition by increasing lean mass, which is closely linked to improvements in glycemic control. Neuromuscular electrical stimulation (NMES) enhances glucose uptake and energy expenditure, independent of changes in body composition. The metabolic effects of combining NMES with RT, however, remain understudied. PURPOSE: To determine if combining NMES with resistance training (RT+NMES) results in greater improvement in glycemic control, energy metabolism, and body composition compared to resistance training alone (RT) in untrained overweight and obese …

Fatigue between practices and games in NCAA DIII female basketball players has yet to be investigated which could provide valuable information in the differences in fatigue patterns thus leading to optimized program design. PURPOSE: The purpose of this study aimed to investigate pre-post changes in neuromuscular performance using the countermovement jump (CMJ) in Division III female basketball players and its associated differences from a practice and a game. METHODS: Eleven Division III female basketball players (n=11, 20±1.41 years; 171.52±7.48 cm; 73.53±12.04) participated …

While exercise is essential for health, motivational barriers often limit regular participation in exercise. This study investigated strategies to enhance exercise engagement by examining the impact of music and social interaction. PURPOSE: To evaluate the effects of music and social interaction on hemodynamic, perceptual, and neuroendocrine responses during high-intensity interval training (HIIT) and blood flow restriction (BFR) training. METHODS: Twenty recreationally active adults (age=22.5 ± 2.3 years) completed a randomized within-participant study involving five sessions: a familiarization, individual HIIT (HIIT-I), group HIIT (HIIT-G), individual BFR (BFR-I), and group BFR (BFR-G). Sessions consisted of whole-body exercises. Researchers recorded heart …
