Abstract:

BACKGROUND: Blackcurrant is rich in anthocyanins that may protect against exercise-induced muscle damage (EIMD) and facilitate a faster recovery of muscle function. We examined the effects of New Zealand blackcurrant (NZBC) extract on indices of muscle damage and recovery following a bout of strenuous isokinetic resistance exercise.

METHODS: Using a double-blind, randomised, placebo controlled, parallel design, twenty-seven healthy participants received either a 3 g·dayNZBC extract (= 14) or the placebo (PLA) (= 13) for 8 days prior to and 4 days following 60 strenuous concentric and eccentric contractions of the biceps brachii muscle on an isokinetic dynamometer. Muscle soreness (using a visual analogue scale), maximal voluntary contraction (MVC), range of motion (ROM) and blood creatine kinase (CK) were assessed before (0 h) and after (24, 48, 72 and 96 h) exercise.

RESULTS: Consumption of NZBC extract resulted in faster recovery of baseline MVC (= 0.04), attenuated muscle soreness at 24 h (NZBC: 21± 10 mm vs. PLA: 40 ± 23 mm,= 0.02) and 48 h (NZBC: 22± 17 vs. PLA: 44 ± 26 mm,= 0.03) and serum CK concentration at 96 h (NZBC: 635± 921 UL vs. PLA: 4021 ± 4319 UL,= 0.04) following EIMD.

CONCLUSIONS: Consumption of NZBC extract prior to and following a bout of eccentric exercise attenuates muscle damage and improves functional recovery. These findings are of practical importance in recreationally active and potentially athletic populations, who may benefit from accelerated recovery following EIMD.
