MPS & RECOVERY FROM RESISTANCE, AEROBIC & HIIT IN OLDER MEN – 2014


Kirsten E. Bell1, Stuart M. Phillips et al
METHODS
– SEDENTARY men (n = 22; 67±4 yrs)
(1) RE – Resistance Exercise: 3 × 10 repetitions: leg extensor and press, 95% 10RM
(2) Aerobic Exercise: 30 minutes, 55%–60% HRmax
(3) HIIT – High Intensity Interval Training: 10 × 1 minute, 95% maximal heart rate [HRmax]

RESULTS
1. Muscle Protein Synthesis was elevated, relative to rest, at 24 and 48 hours following RE and HIIT
2. Increase in Muscle Protein Synthesis was greater following RE versus HIIT at both time points
3. HIIT was the only mode of exercise to increase sarcoplasmic protein fractional synthetic rate 24-hour postexercise
