Background Nowadays, there is a lack of consensus and high controversy about the most effective range motion (ROM) to minimize risk injury maximize resistance training adaptations. Objective To conduct systematic review meta-analysis scientific evidence examining effects full partial ROM interventions on neuromuscular, functional, structural Methods The original protocol (CRD42020160976) was pr...

Rehabilitative body weight supported gait training aims at restoring walking function as a key element in activities of daily living. Studies demonstrated reductions muscle and joint forces, while kinematic patterns appear to be preserved with up 30% support. However, the influence support on architecture, respect fascicle series elastic behavior is unknown, despite this having potential clinic...

OBJECTIVES To describe muscle size and architecture of the gastrocnemius medialis (GM) muscle in eleven adult males with Duchenne Muscular Dystrophy (DMD, age 24.5±5.4 years), and a control group of eleven males without DMD (CTRL, age 22.1±0.9 years). METHODS GM anatomical cross sectional area (ACSA), volume (VOL), physiological cross sectional area (PCSA), fascicle length (Lf) and pennation ...

This study has examined muscle strength and cross-sectional area in a group of 35 healthy untrained male subjects and 8 subjects who had been engaged in a strenuous weight-training programme. The maximum voluntary knee extension force which could be produced by the untrained subjects was 742 +/- 100 N (mean +/- SD). The trained subjects could produce a significantly (p less than 0.001) greater ...

Mechanical properties of the muscle-tendon unit change with aging, but it is not known how these modifications influence the control of lower leg muscles during upright stance. In this study, young and elderly adults stood upright on a force platform with and without vision while muscle architecture and myotendinous junction movements (expressed relative to the change in the moment on the x-axi...

Background Involvement of lower extremity joints in both rheumatoid arthritis (RA) and osteoarthritis (OA) is an important cause declined functional status. Deterioration skeletal muscle performance further contributes to disability. Quadriceps plays role most daily activities. Measuring thickness pennation angle quadriceps compartments can provide knowledge regarding condition. Objectives Aim ...

Component based Hill muscle models are commonly used in musculoskeletal models to predict muscle forces (Zajac, 1989) and have been recommended as the most practical and accurate approach for simulating human movement(van den Bogert et al., 1998; Winters et al., 1987). Hill based models can take several forms, each component of the model representing the properties of one or more tissues in the...

The effect of aging on human gastrocnemius medialis (GM) muscle architecture was evaluated by comparing morphometric measurements on 14 young (aged 27-42 yr) and on 16 older (aged 70-81 yr) physically active men, matched for height, body mass, and physical activity. GM muscle anatomic cross-sectional area (ACSA) and volume (Vol) were measured by computerized tomography, and GM fascicle length (...

Supraspinatus tendon tears are common and lead to changes in the muscle architecture. To date, these changes have not been investigated for the distinct regions and parts of the pathologic supraspinatus. The purpose of this study was to create a novel three-dimensional (3D) model of the muscle architecture throughout the supraspinatus and to compare the architecture between muscle regions and p...
