摘要：Pritchett KL, Pritchett RC, Green JM, Katica C, Combs B, Eldridge M, Bishop P. Comparisons of Post-Exercise Chocolate Milk and a Commercial Recovery Beverage following Cycling Training on Recovery and Performance. JEPonline 2011;14(6):29-39. A recovery beverage that enhances recovery and either maintains or improves the athlete’s workout is highly desired. This study compared low-fat chocolate milk (CHOC) to a commercial recovery beverage (Endurox, CRB) ingested daily over a one-week period in 10 trained cyclists. Cyclists twice maintained their training regimen over a three-week period in which they received either the CHOC or the CRB treatment post workout in a counterbalanced design. Cycling performance at 85% of VO2 max was compared between the two beverages. CK (creatine kinase) levels were assessed at baseline and before the performance trial. A repeated measures ANOVA indicated that CKpre significantly increased (P<0.05) by 64% (+220 UL -1 ) to CKpost for both trials. However, there was no significant difference (P = .95) for CKpost between the two trials (CHOC 570 ± 336 UL-1 , CRB 579 + 383 UL-1 ). There was no significant difference (P = .73) between trials for cycling time to exhaustion at 85% of VO2 max (CHOC 17.4 ± 13.1 min, CRB 15.5 ± 9.9 min). As a recovery beverage, this study suggests that chocolate milk is just as effective as CRB.
