摘要
This study examined the effects of combined anti-inflammatories and specific nutrients on recovery from resistance exercises. Trained individuals （n = 14） performed three sets to failure at a 8-12 repetition maximum load for six resistance exercises, then repeated this workout after 24 h. Participants consumed a protein-carbohydrate shake （330 ml; 20 g protein; 45 g carbohydrate）, vitamin C （1000 mg）, vitamin E （400 I.U.） and ibuprofen （100 mg） immediately after the initial workout. Another dose of vitamin C and ibuprofen were respectively consumed 1 h or 30 min before the second workout. On another occasion （counterbalanced） a placebo of flavored water, two imitation vitamins （gummy candies）, and two replica ibuprofen （sugar pills） were consumed. A 10-cm visual analog scale （VAS） assessed pain, ratings of perceived exertion （RPE）, and ratings of perceived recovery （RPR）. Treatment enhanced performance-based recovery （repetitions after 24h） for the chest press （P 〈 0.010） and latissimus pull-down （P 〈 0.010）. Within-condition comparisons revealed performance decrements （P 〈 0.050） after 24 h for 83% of the exercises under placebo, compared to 50% of exercises under treatment. Treatment enhanced RPR （P = 0.038） compared to placebo, but had no significant effects on residual （P = 0.215） or exercise （P 〉 0.050） pain. RPE was lower under the treatment for the chest press （P = 0.016） and overall workout （P = 0.038） on Day 1, but similar among all exercises on Day 2 （P 〉 0.050）. This treatment may promote increases in performance without increasing pain or RPE.
