72-year-olds did HIIT for six months. The fat-loss edge was 'not clinically meaningful' (maturitas.org)
A six-month randomized trial split 123 adults averaging 72 years old into high-intensity intervals, moderate treadmill work, or a low-intensity control, then scanned body composition with DXA. HIIT preserved lean mass a touch better, fat loss was roughly equal, and the paper called the difference 'small and not clinically meaningful.'
A Carnegie Mellon CS professor in the thread reframed it: the real news is guidance for the elderly quietly shifting away from 'gentle' movement toward genuinely hard training.
