• W4294820367 abstract "Musculotendinous stiffness is important for muscle function, related to soft tissue injury risk in athletes. A few studies suggest acute muscle fatigue may reduce musculotendinous stiffness. Female athletes experience significantly higher risk for soft tissue injury, and fatigue differently than males, suggesting the intriguing possibility that fatigue-induced differences in muscle stiffness may predispose women to enhanced injury risk. PURPOSE: This study assessed changes in stiffness of the vastus lateralis (VL) muscle and patellar tendon (PT) following fatiguing exercise using two different non-invasive measurement tools, ultrasound (US) and digital palpation (DP) in healthy young men and women. METHODS: We recruited 14 young healthy men (9) and women (5). Subjects performed 3 maximum voluntary isometric contractions (MVIC) of the knee extensors (KE) to assess strength and rate of torque development (RTD). Active muscle stiffness was measured at the VL and PT with DP and US at 25%, 50% and 100% MVIC during ramped isometric contractions. Subjects then performed a fatiguing isotonic KE at 30% MVIC until task failure. Immediately following, passive and active stiffness measures were repeated. Results were assessed by two factor (sex/fatigue) repeated measures ANOVA. RESULTS: MVIC and RTD were higher in men (p = 0.015, p = 0.039), but differences were abolished when values were normalized to body size and peak torque, respectively. US based measurements of stiffness were not significantly altered by fatigue, but showed a trend towards a reduction in PT stiffness in males and reduced VL stiffness in females. In contrast, passive VL stiffness increased ~20% following fatigue (p = 0.039) with greater increase in males. Similar to US, active PT stiffness measured with digital palpation tended to be different by sex, with an increase (~17%) with fatigue (p = 0.024) greater in women (p = 0.06). Active VL stiffness was not different between sexes at baseline (p = 0.41), but were different after fatigue (p = 0.004). Females had significantly higher subcutaneous and intramuscular adipose than males (p < 0.001). CONCLUSION: Our data suggest that fatigue alters musculotendinous stiffness in a sex-dependent manner. US and DP present different outcomes, likely due to the inherent differences in measurement of stress and strain." @default.
