Triathlon running elicits hyperventilation, increased heart rate, decreased pulmonary compliance, and exercise induced hypoxaemia. This may be due to exercise intensity, ventilatory muscle fatigue, dehydration, muscle fibre damage, a shift in metabolism towards fat oxidation, and depleted glycogen stores after a 40 km cycle. The energy cost (C<jats:sub>R<\/jats:sub>) of running during the cycle to run transition is also increased over that of control running. The increase in C<jats:sub>R<\/jats:sub>varies from 1.6% to 11.6% and is a reflection of triathlete ability level. This increase may be partly related to kinematic alterations, but research suggests that most biomechanical parameters are unchanged. A more forward leaning trunk inclination is the most significant observation reported. Running pattern, and thus running economy, could also be influenced by sensorimotor perturbations related to the change in posture. Technical skill in the transition area is obviously very important. The conditions under which the preceding cycling section is performed\u2014that is, steady state or stochastic power output, drafting or non-drafting\u2014are likely to influence the speed of adjustment to transition. The extent to which a decrease in the average 10 km running speed occurs during competition must be investigated further. It is clear that the higher the athlete is placed in the field at the end of the bike section, the greater the importance to their finishing position of both a quick transition area time and optimal adjustment to the physiological demands of the cycle to run transition. The need for, and current methods of, training to prepare junior and elite triathletes for a better transition are critically reviewed in light of the effects of sequential cycle to run exercise.<\/jats:p>","DOI":"10.1136\/bjsm.34.5.384","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T10:32:32Z","timestamp":1027765952000},"page":"384-390","source":"Crossref","is-referenced-by-count":111,"title":["Physiological and biomechanical adaptations to the cycle to run transition in Olympic triathlon: review and practical recommendations for training"],"prefix":"10.1136","volume":"34","author":[{"given":"Gregoire P","family":"Millet","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veronica E","family":"Vleck","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2000,10,1]]},"reference":[{"key":"2024051400322846000_34.5.384.1","first-page":"959","volume":"23","year":"1991","journal-title":"Med Sci Sports Exerc"},{"key":"2024051400322846000_34.5.384.2","first-page":"51","volume":"19","year":"1987","journal-title":"Med Sci Sports Exerc"},{"key":"2024051400322846000_34.5.384.3","doi-asserted-by":"publisher","DOI":"10.1249\/00005768-198808000-00010"},{"key":"2024051400322846000_34.5.384.4","doi-asserted-by":"crossref","first-page":"251","DOI":"10.2165\/00007256-199519040-00003","volume":"19","year":"1995","journal-title":"Sports Med"},{"key":"2024051400322846000_34.5.384.5","doi-asserted-by":"publisher","DOI":"10.1249\/00005768-199307000-00017"},{"key":"2024051400322846000_34.5.384.6","doi-asserted-by":"crossref","first-page":"8","DOI":"10.2165\/00007256-199622010-00002","volume":"22","year":"1996","journal-title":"Sports Med"},{"key":"2024051400322846000_34.5.384.7","first-page":"122","volume":"37","year":"1997","journal-title":"J Sports Med Phys Fitness"},{"key":"2024051400322846000_34.5.384.8","first-page":"S86","volume":"18","year":"1986","journal-title":"Med Sci Sports Exerc"},{"key":"2024051400322846000_34.5.384.9","doi-asserted-by":"publisher","DOI":"10.1055\/s-2008-1025731"},{"key":"2024051400322846000_34.5.384.10","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-972633"},{"key":"2024051400322846000_34.5.384.11","doi-asserted-by":"crossref","first-page":"24","DOI":"10.1055\/s-2007-972958","volume":"16","year":"1995","journal-title":"Int J Sports Med"},{"key":"2024051400322846000_34.5.384.12","doi-asserted-by":"publisher","DOI":"10.1007\/s004210050306"},{"key":"2024051400322846000_34.5.384.13","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1139\/h96-001","volume":"21","year":"1996","journal-title":"Canadian Journal of Applied Physiology"},{"key":"2024051400322846000_34.5.384.14","first-page":"S49","volume":"19","year":"1987","journal-title":"Med Sci Sports Exerc"},{"key":"2024051400322846000_34.5.384.15","doi-asserted-by":"crossref","first-page":"131","DOI":"10.1016\/0765-1597(96)89359-2","volume":"10","year":"1995","journal-title":"Science et Sports"},{"key":"2024051400322846000_34.5.384.16","first-page":"25","volume":"3","year":"1986","journal-title":"Annals of Sports Medicine"},{"key":"2024051400322846000_34.5.384.17","first-page":"29","volume":"3","year":"1995","journal-title":"WSPAJ"},{"key":"2024051400322846000_34.5.384.18","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-972642"},{"key":"2024051400322846000_34.5.384.19","doi-asserted-by":"crossref","first-page":"470","DOI":"10.1123\/jab.12.4.470","volume":"12","year":"1996","journal-title":"Journal of Applied Biomechanics"},{"key":"2024051400322846000_34.5.384.20","unstructured":"Witt M.
