Medial gastrocnemius muscle and tendon interaction during gait in typically developing children and children with cerebral palsy
2020
1. IntroductionEfficient gait is dependent on optimal interaction between musclesand tendons [1]. Pathological changes in the extensibility of the MGmuscle fascicles, whole muscle-belly and Achilles tendon have beenreported in children with spastic cerebral palsy (CP) [2]. Studying therelative length of these tissues during gait can improve our understandingof their dynamics and, inferably, the control strategies used inCP. In-vivo dynamic ultrasound imaging has been used to visualise theinteraction between the MG muscle and tendon during 3D gait analysis.However, most studies combined ultrasound imaging of one variable(either fascicles or muscle-belly and tendon) with some form ofmusculosk…
RECRUITMENT OF BICEPS FEMORIS MUSCLE REGIONS AT DIFFERENT RUNNING SPEEDS
2017
Background The majority of hamstring strain injuries (HSIs) occur in the late swing phase of high-speed running when hamstrings work eccentrically. The proximal region of the biceps femoris (BF) seems to be the most common site of injury. Elongation of the fascicles in eccentric contractions is higher in the proximal region compared to the distal region of BF, but the neural background to this phenomenon is not clear. Objective To examine the region-specificity of BF muscle activity at different running speeds. Design Observational study. Running speeds were randomized. Setting Laboratory, amateur level. Participants Football players without acute injury/illness, and without HSI history wer…
Maximal isometric muscle strength and functional ability in daily activities among 75-year-old men and women
2007
The purpose of this study was to analyze whether functional ability in daily activities among 75-year-old men and women is predicted by physical activity, isometric muscle strength and simple function tests. In this representative sample of a general population of 405 75-year-olds, isometric muscle strength and functional ability in daily activities were closely related (odds ratio of disability 1.2–2.1), stressing the importance of strength in the truncus, proximal and distal muscle groups for daily activities. There were strong correlations between physical activity, isometric muscle strength as well as simple function tests and ability to manage daily activities. Those with even light ph…
