The effect of tredmill incline on maximal oxygen uptake, gas exchange and the metabolic response to exercise in the horse

Brief content of the article
The purpose of this experiment was to determine the achievable maximum rate of O2 uptake (VO2max) during level and inclined running and to analyse the relationship between VO2max, lactate treshold (LT) and gas exchange treshold (Tge) during incremental exercise on both the level and inclined treadmill. It was hypothesized that VO2max would be increased on the inclined treadmill, and that the proximity of LT and Tge to VO2max would be increased on the inclined treadmill, and that the proximity of LT and Tge to VO2max would be unchanged. The research was executed in 6 healthy thoroughbreds which completed two maximal runs; one on the level and one on the inclined treadmill (10%). The authors concluded running the Thoroughbred horse on a 10% incline increases VO2max substantially (absolute values for LT and Tge were also increased).
