Absence of Gender Differences in the Fatigability of the Forearm Muscles During Intermittent Isometric Handgrip Exercise
Muscle fatigue gender differences handgrip
2015/3/30
Previous studies have reported women to have a greater resistance to fatigue than men during sustained handgrip exercise, however, observed gender differences in fatigue has been shown to be a functio...
Assessment of the Quadriceps Femoris Muscle in Women after Injury Induced by Maximal Eccentric Isokinetic Exercise with Low Angular Speed
Muscle damage torque electromyography magnetic resonance imaging creatine kinase

Regulation of Muscle Glycogen Repletion, Muscle Protein Synthesis and Repair Following Exercise
Carbohydrate nutrients insulin glucose amino acids
2015/3/13
Recovery from prolonged strenuous exercise requires that depleted fuel stores be replenished, that damaged tissue be repaired and that training adaptations be initiated. Critical to these processes ar...
