Peripheral and central fatigue after muscle-damaging exercise is muscle length dependent and inversely related.
Healthy untrained men performed 10 series of 12 knee eccentric extension repetitions (EE) at 160 degrees /s. The maximal voluntary isometric contraction force of the quadriceps muscle, the maximal rate of electrically induced torque development (RTD) and relaxation (RTR), isokinetic concentric torque at 30 degrees /s, the electrostimulation-induced torque at 20 and 100Hz frequencies were establ...
متن کاملCentral and Peripheral Fatigue During Resistance Exercise – A Critical Review
Resistance exercise is a popular form of conditioning for numerous sport disciplines, and recently different modes of strength training are being evaluated for health benefits. Resistance exercise differs significantly in nature, and several variables determine the direction and range of adaptive changes that occur in the muscular and skeletal system of the body. Some modes of resistance traini...
متن کاملSex Differences in Central and Peripheral Factors of Skeletal Muscle Fatigue
Women generally exhibit greater fatigue resistance than men, due in part to differences in muscle mass. Less muscle mass in women results in decreased oxygen demand and increased oxygen delivery at the same relative workload compared to men and yields greater endurance. The purpose of this study was to examine sex differences in muscle fatigue between male and female athletes matched for muscle...
متن کاملCentral and peripheral fatigue development in the shoulder muscle with obesity during an isometric endurance task
BACKGROUND Fatigue increases the likelihood of developing work-related musculoskeletal disorders and injury. Due to the physiological and neuromuscular changes that accompany obesity, it may alter the fatigue development mechanism and exacerbate injury risk. The upper extremities have the highest incidence rates for work-related musculoskeletal disorders. Therefore, the goals of this study were...
متن کاملCentral and peripheral fatigue in sustained maximum voluntary contractions of human quadriceps muscle.
1. The fatigue of force that occurs during the first 60 s of a maximum voluntary contraction of the human quadriceps has been examined by comparing the voluntary force with that obtained by brief tetanic stimulation at 50 Hz in nine healthy subjects. In three subjects the voluntary force declined in parallel with the tetanic force whereas in the remainder it fell more rapidly, suggesting that c...
