Muscle strength and power are important requirements in many sports. The correlation of jumping performance as manifestation muscle squatting one-repetition maximum (1RM) has been shown several investigations. Correlations with force a linear isokinetic leg press still pending. Since different testing devices produce relationships rotational measurements show conflicting results, further eviden...

OBJECTIVE To evaluate whether changes in muscle strength due to 32 weeks of supervised aquatic training predicted improvements on health-related quality of life (HRQOL). METHODS Thirty women with FM aged 50.8 +/- 8.7 years were randomly assigned to an experimental group (n = 15), performing 3 weekly sessions of 60 min of warm-water exercise; or to a control group (n = 15). HRQOL was evaluated...

During fatiguing upper limb exercise, maintained firing of group III/IV muscle afferents can limit voluntary drive to muscles within the same limb. It is not known if this effect occurs in the lower limb. We investigated the effects of group III/IV muscle afferent firing from fatigued ipsilateral and contralateral extensor muscles and ipsilateral flexor muscles of the knee on voluntary activati...

The influence of training-induced adaptations in skeletal muscle tissue on lipoprotein metabolism was investigated in six healthy men. The knee extensors were studied at rest and during exercise after 8 wk of dynamic exercise training of the knee extensors of one leg, while the other leg served as a control. The trained and nontrained thighs were investigated on different occasions. In the trai...

The aim of the study was to investigate the seasonal variation in isokinetic strength of the knee flexors and extensors, and conventional (H/QCONV) and functional (H/QFUNC) hamstring to quadriceps strength ratios in highly trained adolescent soccer players. The players (n=11; age 17.8±0.3) were measured at the end of the competitive season (autumn), at the beginning and the end of pre-season (w...

Hinge joints occur in the legs of various arthropods, notably Limuhis (Snodgrass, 1952); arachnids; diplopods, chilopods and pauropods (Manton, 19586). At a hinge joint flexion is muscular, but the anatomical form of the joint rarely permits the presence of antagonistic extensors (see Manton, 19580,%. 151 for an exception). In the recent account of the leg muscles of the house spider Tegenaria ...

OBJECTIVES To test a new neurological sign, the "abductor sign," which can distinguish between organic and non-organic leg paresis using synergic movements of the bilateral hip abductors. METHODS The subjects were 33 patients presenting with paresis of one leg, 17 of organic origin and 16 of non-organic origin (hysteria). To test the abductor sign, the examiner told the patient to abduct each...

We recently developed a high intensity one leg dynamic exercise (OLDE) protocol to measure muscle endurance and investigate the central and peripheral mechanisms of muscle fatigue. The aims of the present study were to establish the reliability of this novel protocol and describe the isokinetic muscle fatigue induced by high intensity OLDE and its recovery. Eight subjects performed the OLDE pro...

background :this paper explores the gender-related bilateral differences of extensor and flexor torques of the knee joint at low and high angular velocities in iranian healthy males and females.   methods : 70 healthy subjects (29 males (26.61±4.34 yrs and 41 females with average age of 23.07±3.70 yrs)) were participated in this study. isokinetic peak torque values for knee extensors and flexor...
