Breaking points of human hamstring muscle-tendon complex: A cadaveric study.

Hamstring strain injuries frequently occur during the late swing phase of running; however, the breaking strength of the human hamstring muscle-tendon complexes remains unclear. This study aimed to determine the breaking strength of human hamstring muscle-tendon complexes. To this end, seven cadaveric specimens preserved using the Thiel's method were examined.

Region-specific assessment of the mechanical properties of each hamstring muscle in human cadavers using shear wave elastography.

Background: Understanding regional mechanical properties of individual hamstring muscles is essential for accurately interpreting their functional behavior during elongation. However, how mechanical stress varies within muscles during elongation remains unclear. This study aimed to examine whether mechanical stresses differ among the hamstring muscles and at various regions within each muscle.

Passive muscle tension changes in the biceps femoris long head after biceps femoris short head detachment: A human cadaver study.

The functional role of the biceps femoris short head (BFsh) remains unclear. Clarifying the functional role of each biceps femoris head may provide useful insights into the reduction of biceps femoris long head (BFlh) injuries. This study aimed to clarify whether the passive tension in the BFlh would change with BFsh detachment using cadavers.

Effect of tasks on intramuscular regional differences in rectus femoris elasticity during isometric contraction: An ultrasound shear wave elastography study.

Purpose: This study aimed to investigate intramuscular regional differences and task specificity of rectus femoris (RF) elasticity during isometric contraction.

Methods: Sixteen healthy males (aged 24.3 ± 4.
