Dietary Eicosapentaenoic acid restores Mitochondria in Old Mice

It might be too soon to start popping Eicosapentaenoic acid supplements to boost aging muscles; still the findings are intriguing. Eicosapentaenoic acid but not docosahexaenoic acid restores skeletal muscle mitochondrial oxidative capacity in old mice Mitochondrial dysfunction is often observed in aging skeletal muscle and is implicated in age-related declines in physical function. Early evidence…

Aging, Ultra-Triathlons and Performance

Good news for middle age ultra-triathletes, there is time for improvement. OPEN ACCESS Age-related changes in ultra-triathlon performances Background The age-related decline in performance has been investigated in swimmers, runners and triathletes. No study has investigated the age-related performance decline in ultra-triathletes. The purpose of this study was to analyse the age-related declines in swimming,…
