dc.description.abstract | The main aim of this study was to determine if short-term post exercise recovery, cycling performance and blood analysis were altered when consuming three different beverages with the same amounts of calories, a carbohydrate-only beverage (CHO, 9% carbohydrate) a carbohydrate and casein protein beverage (CHO+Pc, 7% carbohydrate and 2% protein) and a carbohydrate and whey hydrolyzed drink (CHO+Pw, 7% + 2 %). Fifteen male cyclists (VO2peak= 63.4±9.6 ml·kg-1·min-1) performed three trials using a randomly counterbalanced, double-blind design. In each trial one litre of one of the test drinks was consumed in fasting conditions after 1 hour ride at 75% VO2peak. After a two hours recovery period the cyclists rode 20 km at the rider’s maximum speed for this distance. The results showed no significant differences in the 20-km ride when consuming the CHO (1770±210 s), the CHO+Pc drink (1819±185 s) or the CHO+Pw (1803±201). Post-exercise creatine kinase (CK) was not significantly different between treatments. However, serum insulin concentrations were higher during recovery when CHO+Pc and CHO+Pw beverages were consumed (P<0.05). Glucagon and lactic acid levels increased more on the CHO than on the CHO+Pc and CHO+Pw treatments (P<0.05) at the end of the 20 km test. Within the context of this experimental design, the CHO+Pc and CHO+Pw beverages showed different physiological effects than the CHO drink. One purported mechanism indicates muscle glycogen re-synthesis is enhanced when protein is added to a CHO recovery formula. The CHO+Pw and CHO+Pc drinks could be recommended for improving recuperation from intensive exercise. Although this was not reflected in post-recovery exercise performance in this 20 km test, a harder or longer test may be more affected by the physiological parameters especially in the last kilometres of the test. | en |
