Sensor location affects skeletal muscle contractility parameters measured by tensiomyography
<p><span>Tensiomyography (TMG) is a non-invasive method for measuring contractile properties of skeletal muscle that is increasingly being used in research and practice. However, the lack of standardization in measurement protocols mitigates the systematic use in sports medical settings. Therefore, this study aimed to investigate the effects of lower leg fixation and sensor location on TMG-derived parameters. Twenty-two male participants underwent TMG measurements on the m. biceps femoris (BF) in randomized order with and without lower leg fixation (fixed vs. non-fixed). Measurements were conducted at 50% of the muscle's length (BF-mid) and 10 cm distal to this (BF-distal). The sensor location affected the contractile properties significantly, both with and without fixation. Delay time (T<sub>d</sub>) was greater at BF-mid compared to BF-distal (fixed: 23.2 ± 3.2 ms vs. 21.2 ± 2.7 ms, <em>p</em> = 0.002; non-fixed: 24.03 ± 4.2 ms vs. 21.8 ± 2.7 ms, <em>p</em> = 0.008), as were maximum displacement (D<sub>m</sub>) (fixed: 5.3 ± 2.7 mm vs. 3.5 ± 1.7 mm, <em>p</em> = 0.005; non-fixed: 5.4 ± 2.5 mm vs. 4.0 ± 2.0 mm, <em>p</em> = 0.03), and contraction velocity (V<sub>c</sub>) (fixed: 76.7 ± 25.1 mm/s vs. 57.2 ± 24.3 mm/s, <em>p</em> = 0.02). No significant differences were revealed for lower leg fixation (all <em>p</em> > 0.05). In summary, sensor location affects the TMG-derived parameters on the BF. Our findings help researchers to create tailored measurement procedures in compliance with the individual goals of the TMG measurements and allow adequate interpretation of TMG parameters.</span></p>

Multiomic analysis of racehorses identifies the role of gut microbial butyrate in enhancing athletic performance via the gut-muscle/mitochondrial axis
<p>Gut microbes and their metabolites play a vital role in the health and host physiology, but how specific bacterial functions contribute to the exceptional athletic performance of racehorses needs to be better understood. Here, we identify an association of gut butyrate-producing bacteria with athletic performance in racehorses. Butyrate-producing bacteria and genes related to in butyrate synthesis were significantly enriched in the racehorse gut, and the targeted metabolomic results verified this conclusion. Supplementing butyrate in mice, we demonstrated that butyrate is sufficient to increase treadmill run time performance. We also show that butyrate improves the host response to exercise, significantly reducing inflammation in the small intestine, altering muscle fibre type in skeletal muscle, and increasing muscle mitochondrial function and activity. We also reported that the role of gut microbial butyrate might be conserved in the racehorse and human athlete. Overall, our study provides novel insights into gut microbial functions and paves the way for improving athletic performance by targeted gut microbiome manipulation.Gut microbes and their metabolites play a vital role in the health and host physiology, but how specific bacterial functions contribute to the exceptional athletic performance of racehorses needs to be better understood.
