Subtalar and knee joint interaction during running at various stride lengths.
AIM It has been suggested that during running proper coordination between subtalar pronation/supination and knee flexion/extension via tibial rotation is important to attenuate ground reaction impact forces (GRIF). Lack of coordination over time may produce a wide range of injuries. It was hypothesized that increasing stride length would result in higher GRIF. It was also hypothesized that alte...
متن کاملMechanical efficiency of treadmill running exercise: effect of anaerobic-energy contribution at various speeds.
OBJECTIVES Mechanical efficiency (ME) describes the ratio between mechanical (PMECH) and metabolic (PMET) power. The purpose of the study was to include an estimation of anaerobic energy expenditure (AnE) into the quantification of PMET using the accumulated oxygen deficit (AOD) and to examine its effect on the value of ME in treadmill running at submaximal, maximal, and supramaximal running sp...
متن کاملMechanical loads at the knee joint during deep flexion.
There is a lack of fundamental information on the knee biomechanics in deep flexion beyond 90 degrees. In this study, mechanical loads during activities requiring deep flexion were quantified on normal knees from 19 subjects, and compared with those in walking and stair climbing. The deep flexion activities generate larger net quadriceps moments (6.9-13.5% body weight into height) and net poste...
متن کاملAsynchrony between subtalar and knee joint function during running.
PURPOSE It has been suggested that during running proper coordination between subtalar joint pronation/supination and knee joint flexion/extension via tibial rotation is important to attenuate ground reaction impact forces (GRIF). Lack of coordination may produce over time a wide range of injuries. The goal of this study was to investigate the relationship between subtalar pronation/supination ...
متن کاملJoint Coupling Variability and Knee Pain During Running
Introduction The knee and subtalar joint actions are related by the internal/external rotation motion of the tibia during the support phase of running. It has been suggested that maximum knee flexion should occur at the same time as maximum subtalar eversion during which time the tibia undergoes internal rotation (Bates et al., 1978). Asynchronous timing between knee joint flexion and ankle joi...
