Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to investigate potential relations of ultrasound-based muscle architecture parameters and isometric knee flexor muscle strength (IKFS) in healthy individuals. IKFS was measured for twenty participants (22.15±2.41 y.o; 8 females, 12 males) by a hand-held dynamometer. Investigated parameters were total and individual cross-sectional areas (CSA), Muscle-Thickness (MT), and pennation-angle (PA) for Biceps Femoris-long head (LBF), Semitendinosus (ST) and Semimembranosus (SM) muscles at 25%, 50% and 75% length of the thigh.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The images of hamstring muscles were taken by a US device (Toshiba Aplio 500, Japan) with a linear probe (10-12 MHz, with a footprint of 52 mm).

For each participant, maximum voluntary IKFS was measured from the non-dominant side in the prone position with foot and ankle stayed outside of the bed. Maximum IKFS (20 limbs) was measured by an HHD (A Lafayette Model 01165) (Lafayette, IN) at 15° knee flexion in prone lying position
