Comparative analysis of hand-held and stationary ultrasound for detection of sarcopenia in acutely hospitalised older adults-a validity and reliability study.

Background And Purpose: Sarcopenia is a growing health concern among geriatric patients. Early diagnostics is importance to intervene and better muscle status and thus physical function. Ultrasound can be a valuable tool for patient-near diagnostics of sarcopenia.

Effects of low load exercise with and without blood-flow restriction on microvascular oxygenation, muscle excitability and perceived pain.

This paper aimed to examine the acute effect of low-load (LL) exercise with blood-flow restriction (LL-BFR) on microvascular oxygenation and muscle excitability of the vastus medialis (VM) and vastus lateralis (VL) muscles during a single bout of unilateral knee extension exercise performed to task failure. Seventeen healthy recreationally resistance-trained males were enrolled in a within-group randomized cross-over study design. Participants performed one set of unilateral knee extensions at 20% of one-repetition maximum (1RM) to task failure, using a LL-BFR or LL free-flow (LL-FF) protocol in a randomized order on separate days.
