High-intensity resistance training (HRT) has been recommended to offset age-related loss in muscle strength and mass. However, part of the elderly population is often unable to exercise at high intensities. Alternatively, low-intensity resistance training with blood flow restriction (LRT-BFR) has emerged. The purpose of this study was to compare the effects of LRT-BFR and HRT on quadriceps musc...

BACKGROUND The use of sports massage is very common in the athletic community. However, only a few studies have shown any therapeutic effect of massage. HYPOTHESIS Sports massage can improve the recovery after eccentric exercise. STUDY DESIGN Prospective randomized clinical trial. METHODS Sixteen subjects performed 300 maximal eccentric contractions of the quadriceps muscle bilaterally. M...

Previous investigations have examined the effect of gravity correction on hamstring and quadriceps force and reciprocal muscle group ratios when tested from a seated position. The effect of gravity correction on these values when knee extension is tested from supine and knee flexion from prone has not been determined. This study tested 48 females for concentric and eccentric average force of th...

OBJECTIVE Congenital generalized lipodystrophy (CGL) is an autosomal recessive genetic disorder characterized by almost complete absence of adipose tissue, muscular appearance, and severe insulin resistance since birth. We investigated whether insulin resistance in CGL patients is associated with abnormal muscle morphology and whether increased muscularity imparts increased muscle strength and ...

We determined the physiological effects of exercise training on exercise capacity and quadriceps muscle function in patients with idiopathic pulmonary arterial hypertension (iPAH). In total, 19 clinically stable iPAH patients (New York Heart Association II-III) underwent a supervised exercise training programme for the duration of 12 weeks. Maximal capacity, endurance capacity and quadriceps fu...

The aim of this study was to establish whether asymmetry of the strength of the leg and trunk musculature is more prominent in rowers than in controls. Nineteen oarsmen and 20 male controls matched for age, height and body mass performed a series of isokinetic and isometric strength tests on an isokinetic dynamometer. These strength tests focused on the trunk and leg muscles. Comparisons of str...

  Background and Objective: Hamstring to quadriceps strength ratio (H/Q) is one of the most important knee injury risk factors. The aim of this research was to compare H/Q in female athletes and nonathletes. Materials and Methods: The subjects of this research were 28 female athletes with mean age, height and weight of 20.21±3.05 y, 163.48±5.73 cm and 57.74±7.01 kg, as well as 12 female nonathl...

Inactivity is a recognized compounding factor in sarcopenia and muscle weakness in old age. However, while the negative effects of unloading on skeletal muscle in young individuals are well elucidated, only little is known about the consequence of immobilization and the regenerative capacity in elderly individuals. Thus the aim of this study was to examine the effect of aging on changes in musc...

Purpose: Patellofemoral Pain Syndrome (PFPS) is among the most prevalent complaints observed in healthcare clinics. This group of patients encounters Pelvic Drop (PD) and Dynamic Knee Valgus (DNV); its’ causes have been reported as pain and decreased muscle strength. The current study aimed to explore the effects of a 12-week Sensorimotor Exercise (SME) on pain, strength, PD, and DNV in males w...

Introduction: It is suggested that quadriceps muscle has an important role in stability & mobility of Knee joint in athletics and normal individuals therefore, the purpose of this study was evaluation of the strength in Power Athletics (PA) and Normal Un-trained Individuals (NUI) groups. Methods and Materials: 31 Females (20 NUI & 11 PA) participated in this study. For measuring the strength, e...
