Objectives: Needle electromyography (EMG) has an important role in the diagnosis of poliomyelitis. Since needle EMG is a painful and time consuming procedure, selecting most effective muscles for important. We aimed to determine clinically or subclinically affected regions polio survivors by examining minimum number with EMG. Methods: Polio weakness at least one limb were included this retrospe...

[Purpose] This study examined age-related differences in muscle control for support and propulsion during walking in both males and females in order to develop optimal exercise regimens for muscle control. [Subjects and Methods] Twenty elderly people and 20 young people participated in this study. Coordinates of anatomical landmarks and ground reaction force during walking were obtained using a...

[Purpose] This study was performed to examine the relationship between physical performance and muscle properties during police cadet training. The study's hypothesis was that improved physical performance brought about by training, would in turn cause a reduction in muscle flexibility. [Subjects and Methods] Fifty-nine police cadets were included in this study. Standard fitness tests and quant...

The vertebrate musculoskeletal system is composed of skeletal levers powered by muscles. Effective mechanical advantage (EMA) and muscle properties influence organismal performance at various tasks. Anatomical mechanical advantage (AMA) is a proxy for EMA that facilitates the study of preserved specimens when many muscles or many species are of interest. AMA is the quotient of in-lever to out-l...

Mathematical calculations of muscle forces often require an estimate of a given muscle’s capacity to generate force. A traditional way of expressing a muscle’s fora generating capacity is in terms of its ‘physiological cross-sectional area’ (degned by muscle volume or muscle mass divided by either gross musck length or muscle fiber length with or without accounting for pennation) (Brand et al.....
