The maximal force a muscle can exert depends on its length,which has been explained by the sliding filament theory on the sarcomere level.1 A longer muscle can act over a greater range of motion and has more sarcomere...
The first in vivo measurements of serial sarcomere number in human muscles before and after eccentric strength training have just been published and the results will interest anyone involved with sport or health:Train...

Background Eccentric training,such as Nordic hamstring exercise(NHE)training,is commonly used as a preventive measure for hamstring strains.Eccentric training is believed to induce lengthening of muscle fascicles and ...
This work was supported by the Sao Paulo Research Foundation(FAPESP),which provided scholarships to HSL(Grant No.2021/09393-1);RVB(Grant No.2021/08644-0)and a research grant to FMA(Grant No.2020/14715-5).The financial sponsors played no role in the design,execution,analysis and interpretation of data,or the writing of the study。
Background:Impairments in hamstring strength,flexibility,and morphology have been associated with altered knee biomechanics,pain,and function.Determining the presence of these impairments in individuals with gradual-o...
Background: Netball is a popular sport. Due to high impact and quick movement, there is an enormous load on the lower extremities which increases the risk for injury. Aim: The aim of this study was to investigate the ...
This study analyzed the difference between using a downward breaststroke kick and a horizontal breaststroke kick in a sample of world class elite swimmers.We compared average muscle activity of the gluteus maximus,qua...
Background:For the past 30 years,the hamstring(H)-to-quadriceps(Q)(H:Q)torque ratio has been considered an important index of muscle strength imbalance around the knee joint.The purpose of this systematic review was t...
Purpose To evaluate the efficacy and safety of radial extracorporeal shock wave therapy (rESWT) according to total number of pulses on hamstring muscle spasticity in children with spastic type cerebral palsy (CP).Meth...
