AB  - A beverage containing protein (PRO) and carbohydrate (CHO) may have an ergogenic 
      effect on endurance performance. However, evidence regarding its efficacy on 
      similar conditions to athletes' race day is still lacking. The objective of this 
      study was to compare the effects of 3 different nutritional supplementation 
      strategies on performance and muscle recovery in a duathlon protocol. Thirteen 
      male athletes (29.7 +/- 7.7 years) participated in 3 simulated Olympic-distance 
      duathlon trials (SDTs) under 3 different, randomly assigned supplementation 
      regimens: CHO drink (75 g CHO), isocaloric CHO plus PRO drink (60.5 g CHO and 
      14.5 g PRO), and placebo drink (PLA). Supplements were offered during the cycling 
      bout. Blood samples were collected before, immediately after, and 24 h after each 
      SDT for creatine kinase (CK) analysis. Isometric peak torque (PT) was measured 
      before and 24 h after each SDT. The primary outcome measure was the time to 
      complete the 5-km running section (t(5km)) at a self-selected pace. There was no 
      difference in t(5km) between CHO (1270.3 +/- 130.5 s), CHO+PRO (1267.2 +/- 138.9 s), 
      and PLA (1275.4 +/- 120 s); p = 0.87, effect size (ES) </= 0.1. Pre-post changes for 
      PT and CK were not significant for any of the 3 conditions (PT: p = 0.24, ES </= 
      0.4; CK: p = 0.32, ES = 0.3-1.04). For endurance sports lasting up to 2 h, with a 
      pre-exercise meal containing CHO at 1.5 g.kg(-1), supplementation with CHO or 
      CHO+PRO does not offer additional benefits for performance and muscle recovery 
      when compared with PLA.
