Cardiovascular Response to Exercise and Training in the Horse

摘要: The quality of the overall response to exercise in horse is very similar that seen man and laboratory animals; differences are mainly quantitative persist when relative body weight taken into account. apparently greater flow capacity equine muscle bed during maximal whole-body implicates extent central circulatory adaptations as limiting factor performance but implies a role for increase arteriolar capacitance/muscle capillarity an appropriate intense endurance training. blood oxygen-carrying often quoted major component animal's superior aerobic work capacity, although measured a-vO2 only 2 3 ml than found elite athletes. In fact, comparison published data reveals improved accounts 23 per cent difference, increased Qc remaining 77 oxygen consumption horse. which can appears represent its performance. It frequently observed there have been far improvements human athletic race-horse, this difference usually attributed application scientific training methods athlete. has also suggested may reached limit adaptive ability. pulse at least 0.6 kg beat compared with 0.35 man, 90 whole extraction, 80 higher flow, capability increasing Vo2 max by 35 times. These levels would appear be difficult improve upon. However, insufficient research performed firmly state true maxima horse, current does not reveal what capable responding even conventional methods. improvement such could provide some objective guidance further anticipated. A consistent finding majority studies reviewed tendency results show lack statistical significance, particularly frustrating researcher trends initial hypotheses. This arises because small group sizes inherent variability test population.(ABSTRACT TRUNCATED AT 400 WORDS)
