Abstract

Carbohydrate-protein–based supplements have been proposed for maximizing postexercise recovery. This study compared the effects of post-workout supplementation ingesting a multi ingredient (MTN) vs. carbohydrate alone (CHO) on the recovery of muscle function and perceived muscle soreness (DOMS) after hard resistance workouts. In a double-blinded, crossover design, 10 resistance trained males (26.9±7.4 years) performed two identical 5-day intervention periods while ingesting either MTN or CHO.

The participants performed one workout per day during the first three days. thereafter, they were assessed 1-h, 24-h and 48-h after the completion of the third workout-session.

Primary outcome was tensiomyography [muscle displacement (Dm), contraction time (Tc), and contraction velocity (Vc)] of the vastus medialis (VM) and biceps femoris long head (BFLH). Secondary outcomes were performance and DOMS. At 24-h, both conditions decreased (p<0.05) Dm (MTN -1.71±1.8, CHO -1.58±1.46 mm) and Vc (MTN -0.03±0.03, CHO 0.03±0.04 m.s-1) in VM. At 48-h all tensiomyography variables were recovered under the MTN while remained depressed (p<0.01) in CHO (VM, Dm 1.61±1.60, Vc -0.04±0.04 m.s-1; BFLH, Dm 1.54±1.52, Vc -0.02±0.02 m.s-1). Vertical jump performance decreased in CHO, but not in MTN. Although both conditions decreased upper body strength and power at 1-h, values returned to baseline in 24-h for MTM while needed 48-h in CHO. DOMS similarly increased at both 24-h and 48-h in both conditions. Compared to the ingestion of only carbohydrates, post-workout multiingredient supplementation seems to hasten recovery of muscular contractile properties and performance without attenuating DOMS after hard resistance workouts.
