BACKGROUND Human Immunodeficiency Virus positive subjects present impairment in muscle function, neural activation, balance, and gait. In other populations, all of these factors have been associated with muscle strength asymmetry. OBJECTIVE To investigate the existence of muscle strength asymmetry between dominant and non-dominant lower limbs and to determine the hamstrings-to-quadriceps stre...

BACKGROUND Previous studies have shown that preloading an antagonist muscle may increase the acute agonist neuromuscular performance. In addition, studies have suggested that very short-term resistance exercise (RE) programs may also be useful to increase strength and muscular performance. OBJECTIVES To evaluate the effects of three days of RE using a reciprocal action method on the muscular ...

3 Purpose: To examine and compare sex-related differences in the functioning of the hamstrings 4 and quadriceps muscles and the isokinetic hamstrings eccentric to quadriceps concentric 5 functional ratio (H/QFUNC) . 6 Methods: Fifty male and 46 female young adults completed this study. Each participant carried 7 out an isokinetic assessment to determine isokinetic concentric and eccentric torqu...

The presents study investigated the effects of between-set interventions on neuromuscular function of the knee extensors during six sets of 10 isokinetic (120°·s(-1)) maximal concentric contractions separated by three minutes. Twelve healthy men (age: 23.9 ± 2.4 yrs) were tested for four different between-set recovery conditions applied during two minutes: passive recovery, active recovery (cyc...

ISOKINETIC RANGE OF MOTION (ROM) HAS THREE DISTINCT PHASES rate of velocity development (RVD), load range (LR), and deceleration (DCC). The purpose of this study was to determine if differences in isokinetic knee extension/flexion LR exist between body positions. Ten subjects (4 males and 6 females, age 29.3 ± 5.4 yrs, ht 1.71 ± 0.10 m, wt 71.9 ± 12.9 kg) volunteered to participate in the seate...

BACKGROUND Abnormalities of cardiac structure and function are common in a wide range of populations including those with and without established clinical cardiovascular disease (CVD). This study reports the prevalence of left ventricular hypertrophy (LVH), the four patterns of LV geometry and establishes clinical characteristics and five-year outcomes of each group in people of advanced age. ...

INTRODUCTION A conditioning maximal voluntary muscle action (MVC) has been shown to induce postactivation potentiation, that is, improved contractile muscle properties, when muscles are contracted isometrically. It is still uncertain how the contractile properties are affected during ongoing muscle length changes. The purpose of this study was to investigate the effects of a 6-s conditioning MV...
