Influence of concentric and eccentric resistance training on architectural adaptation in human quadriceps muscles.
Studies using animal models have been unable to determine the mechanical stimuli that most influence muscle architectural adaptation. We examined the influence of contraction mode on muscle architectural change in humans, while also describing the time course of its adaptation through training and detraining. Twenty-one men and women performed slow-speed (30 degrees /s) concentric-only (Con) or...
متن کاملThe Relationships among Isometric, Isotonic, and Isokinetic Concentric and Eccentric Quadriceps and Hamstring Force and Three Components of Athletic Performance.
This study was supported in part by a grant from the Foundation for Physical Therapy, Inc. The purpose of this study was to compare the relationships among isometric, isotonic, and isokinetic concentric and eccentric quadriceps and hamstring forces and three components of athletic performance in college-aged, male athletes. Bilateral quadriceps and hamstring muscle torque were obtained (N = 39)...
متن کاملHamstring injuries in sprinters. The role of concentric and eccentric hamstring muscle strength and flexibility.
Eleven sprinters with recent hamstring injuries were compared with nine uninjured runners. The flexibility of the hamstrings and the eccentric and concentric muscle torque were measured in the hamstrings and quadriceps muscles at different angular velocities. Sprinters with a previous hamstring injury had significantly tighter hamstrings than uninjured sprinters had. The uninjured sprinters had...
متن کاملEccentric versus Concentric Contraction of Quadriceps Muscles in Treatment of Chondromalacia Patellae
Chondromalacia patellae is a disorder often accompanied by patellofemoral instability. This can be simply a reflex inhibition of the quadriceps muscle secondary to pain. The eccentric and concentric contraction exercises are beneficial in strengthening of the quadriceps muscles and treatment of chondromalacia patellae. This study was conducted to compare between eccentric contraction and concen...
متن کاملEffect of cold treatment on the concentric and eccentric torque-velocity relationship of the quadriceps femoris By: Kerriann Catlaw
This study examined the effect of cold treatment on the force-velocity relationship of the quadriceps muscle of 16 athletes. Each subject performed three maximal concentric and eccentric quadriceps contractions on the Kin-Corn at 25, 50, 75, 100, 125, 150, 175 and 2000s-1. On one of two testing sessions, subjects received a 20 min ice application prior to testing, and for the remaining session,...
