Repeated sprint training in hypoxia (RSH) was recently shown to improve repeated sprint ability (RSA) in cycling. This phenomenon is likely to reflect fiber-type dependent, compensatory vasodilation and, therefore, our hypothesis was that RSH is even more beneficial for activities involving upper-body muscles, such as double-poling during cross-country skiing. In ...

Previous studies reported that adding protein (PRO) to carbohydrate (CHO) solutions enhances endurance performance. The ergogenic effect may be a function of additional protein/amino acid calories, but this has not been examined. Additionally, although supplemental L-alanine (ALA) is readily oxidized during exercise, the subsequent impact on metabolism and prolonged endurance ...
