Michael J. Hamlin (Mike) is Associate Professor of Exercise and Sport Science and Sport Scholarship Academic Advisor, Department of Tourism, Sport and Society Lincoln University, Christchurch New Zealand. Dr. Hamlin is the author of more than 90 referred journal articles and book chapters, presented at more than 100 national and international conferences and is the reviewer for many exercise and sport science journals. A member of numerous professional societies, he received his B.Ph.Ed degree (1990) in exercise prescription from Otago University, Dunedin, his M.H.M.S. degree (1995) in exercise physiology from the University of Queensland, Brisbane, and his Ph.D. degree (1999) from Otago University, Dunedin. Mike is a Fellow of the European College of Sport Sciences and a past board member of Sport and Exercise Science New Zealand. Among other areas, Dr. Hamlin specializes in altitude training, particularly the effects of various forms of hypoxic training on athletic performance. Dr. Hamlin has been an altitude training consultant for Bike New Zealand, The Netherlands Triathlon Team, The New Zealand Triathlon team, High Performance Sport New Zealand and the New Zealand Rugby Union.
Active and Passive Hypoxic Training: Effects on Athletic Performance and Health.
A reduction in inspired oxygen creates a multitude of downstream events affecting almost all tissues in the body. For example, in a sporting context, a reduction in the partial pressure of oxygen in the inspired air results in fewer oxygen molecules being transported to the working muscle, ultimately challenging aerobic metabolism and compromising endurance ability. However, while endurance performance is compromised in low oxygen environments, the additional challenge of hypoxia as a training stimulus can result in beneficial adaptation to the athlete. Indeed both passive hypoxic exposure (passive hypoxic training) and training in hypoxia (active hypoxic training) have been shown to improve endurance performance in sub-elite athletes (likely smaller improvement in elite athletes). More recently such training has also been shown to improve anaerobic and repeated sprint performance in athletes. Outside of the sporting arena, active and passive hypoxic training has been used in an attempt to improve the health of clinical and non-clinical (but at risk) populations. Such training has been shown to improve cardiovascular parameters such as blood pressure, heart rate variability and ventricular ejection fraction. This presentation will include recent data from Dr. Hamlin’s research group on the effects of active hypoxic training on athletic performance, in particular the benefit such training may have on team sport athletes. The presentation will also investigate the beneficial effects of passive hypoxic training on heart rate variability and cardiovascular disease risk in sedentary at risk individuals.
