PURPOSE To report the association of lean body mass with nutritional, social and economic factors and its functional consequences in free living healthy elderly subjects. MATERIAL AND METHODS Healthy elderly subjects of low socioeconomic level were studied. Monthly income, marital status, anthropometric measures and fall risk were assessed. Mini Nutritional Assessment score was calculated. Bo...

Magnetic resonance-based assessment of quadriceps muscle fat has been proposed as surrogate marker in sarcopenia, osteoarthritis, and neuromuscular disorders. We presently investigated the association of quadriceps muscle fat with isometric strength measurements in healthy males using chemical shift encoding-based water-fat magnetic resonance imaging. Intermuscular adipose tissue fraction and i...

BACKGROUND Grip strength is widely used for estimating whole body strength but there is a lack of information relating to grip endurance. Comparison between endurance of different muscle groups has received little attention. The main aim of the present study was to determine the endurance characteristics of hand grip and quadriceps muscles in healthy young adults and then to examine the associa...

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 Disability is common in a proportion of patients after anterior cruciate ligament reconstruction (ACL-R). Neuromuscular quadriceps deficits are a hallmark impairment after ACL-R, yet the link between muscle function and disability is not understood. PURPOSES To evaluate the ability of quadriceps strength and cortical excitability to predict self-reported disability in patients with...

The study investigates the effects of the 11+ and HarmoKnee injury prevention programmes on knee strength in male soccer players. Under-21-year-old players (n=36) were divided equally into: the 11+, HarmoKnee and control groups. The programmes were performed for 24 sessions (20-25 min each). The hamstrings and quadriceps strength were measured bilaterally at 60°·s(-1), 180°·s(-1) and 300°·s(-1)...

PURPOSE The purpose of this study was to evaluate the quadriceps and hamstring muscle strength and hamstring-to-quadriceps (HQ) ratio, as well as the relationships of these parameters with dynamic balance, in patients with anterior cruciate ligament (ACL) rupture. MATERIALS AND METHODS We compared 25 patients diagnosed with chronic unilateral ACL tears and 25 age-matched healthy volunteers. T...

The study was conducted on two hundred patients ranging in age from 40 to 70 years with established osteoarthritis knee to examine the association of quadriceps strength with pain and disability of knee osteoarthritis. In addition the relationships between various components of health related fitness, pain, effusion and disability were also examined in the present study. Quadriceps strength see...

This study aims to determine the relationship between quadriceps angle, anthropometric measurements and muscle strength. The angle (Q angle) consider clinically as a very important parameter which displays biomechanical effect of on knee it is also crucial factor for proper posture movement knee. Quadriceps routinely regularly used an assessment during diagnosis many knee-related problems. show...

Objective: This study aimed to compare and evaluate the efficacy of eccentric concentric training on quadriceps femoris muscle architecture, strength proprioception in healthy young people. 
 Materials Methods: Sixty subjects were divided into two groups (n=30), (n=30). The outcome measurements Quadriceps Femoris (QF) knee proprioception. was carried out subjects’ dominant side leg (right)...
