NR May Slow Muscle Aging Clocks While Hard Interval Training Speeds Some Up
This study suggests NR and HIIT may affect muscle epigenetic aging clocks in opposite ways.
Nicotinamide riboside, a popular NAD+ booster, was linked to slower epigenetic aging in muscle across several aging clocks. Surprisingly, high-intensity interval training pushed some of those clocks in the opposite direction, appearing to speed up the pace of aging. The two interventions worked against each other on these markers, which is unexpected and needs more study.
