Knee alignment is suggested to be a factor affecting each quadriceps femoris muscle size, and knee alignment such as Q-angle differs between men and women. Also, training can induce inhomogeneous hypertrophy among the quadriceps femoris, thereby leading to different component characteristics of the muscles. If Q-angle is a major determinant of the quadriceps femoris muscularity, it is hypothesi...

The specific aim of this study was to quantify muscle activity while performing squat with technique variations. Eight healthy volunteers performed squats under 5 types of foot positions: neutral position, under a 10o descending wedge, under a 10o ascending wedge, under a 10o medial wedge and under a 10o lateral wedge. It was evaluated electromyographic data of vastus medialis oblique, vastus l...

The objective of the study was to investigate effects a training program with Pilates Method on muscle fatigue in youth soccer players. Fifteen male players, sub 13-15 category, mean age 13.27 ± 0.45 years, were randomly divided into two groups: Control group (n = 7) and 8). In group, an additional protocol performed alone. both groups, concentration cytokines (TNFα, IL-10), electrical activity...

This report outlines the use of a customized false-color 3D computed tomography (CT) protocol for the imaging of the rectus femoris of spinal cord injury (SCI) patients suffering from complete and permanent denervation, as characterized by complete Conus and Cauda Equina syndrome. This muscle imaging method elicits the progression of the syndrome from initial atrophy to eventual degeneration, a...

Results: There have been no studies directly comparing different return to play approaches. Studies have instead concentrated on recurrence risk factors and prognosis assessment, particularly for hamstring injuries. There is some literature support for risk factors for recurrence such as persisting strength deficits, larger injuries seen on diagnostic imaging, players in high-risk positions or ...

Many randomized controlled trials utilizing resistance training have shown improvements in muscle activation older adults. However, these programs lack applicability to community-dwelling adults due several challenges. Therefore, the purpose of this study was test effects an eight-week community-based program on Eight females (age: 61 ± 4 years, body mass index (BMI): 31.7 5.7 kg/m2) were enrol...

The aim of this study was to investigate the changes in activation of the musculoskeletal system in response to soft-tissue vibrations with different compression conditions (externally applied) in a drop-jump landing task. Twelve trained male participants were instructed to perform drop-jump landings from 3 heights in compression shorts (CS) and regular shorts without compression (CC). External...

We examined the size of the four muscles of the quadriceps femoris in young and old men and women to assess whether the vastus lateralis is an appropriate surrogate for the quadriceps femoris in human studies of aging skeletal muscle. Ten young (24 +/- 2 yr) and ten old (79 +/- 7 yr) sedentary individuals underwent magnetic resonance imaging of the quadriceps femoris after 60 min of supine rest...
