Eight male elite BMX riders volunteered for the study. Each rider performed three, 10\u2010s maximal sprints on an Olympic standard indoor BMX track. The riders\u2019 bicycles were fitted with a portable SRM power meter. Each rider performed the three sprints using gear ratios of 41\/16, 43\/16 and 45\/16 tooth. The results from the 41\/16 and 45\/16 gear ratios were compared to the current standard 43\/16 gear ratio. Statistically, significant differences were found between the gear ratios for peak power (<jats:italic>F<\/jats:italic>(2,14) = 6.448; <jats:italic>p<\/jats:italic> = .010) and peak torque (<jats:italic>F<\/jats:italic>(2,14) = 4.777; <jats:italic>p<\/jats:italic> = .026), but no significant difference was found for time to peak power (<jats:italic>F<\/jats:italic>(2,14) = 0.200; <jats:italic>p<\/jats:italic> = .821). When comparing gear ratios, the results showed a 45\/16 gear ratio elicited the highest peak power,1658 \u00b1 221\u2005W, compared to 1436 \u00b1 129\u2005W and 1380 \u00b1 56\u2005W, for the 43\/16 and 41\/16 ratios, respectively. The time to peak power showed a 41\/16 tooth gear ratio attained peak power in \u22120.01\u2005s and a 45\/16\u00a0in 0.22\u2005s compared to the 43\/16. The findings of this study suggest that gear ratio choice has a significant effect on peak power production, though time to peak power output is not significantly affected. Therefore, selecting a higher gear ratio results in riders attaining higher power outputs without reducing their start time.<\/jats:p>","DOI":"10.1080\/17461391.2016.1210237","type":"journal-article","created":{"date-parts":[[2016,8,3]],"date-time":"2016-08-03T06:08:14Z","timestamp":1470204494000},"page":"127-131","update-policy":"https:\/\/doi.org\/10.1080\/tandf_crossmark_01","source":"Crossref","is-referenced-by-count":6,"title":["Effect of gear ratio on peak power and time to peak power in BMX cyclists"],"prefix":"10.1002","volume":"17","author":[{"given":"Lee P.","family":"Rylands","sequence":"first","affiliation":[{"name":"College of Life and Natural Sciences University of Derby Buxton UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simon J.","family":"Roberts","sequence":"additional","affiliation":[{"name":"Faculty of Education, Community and Leisure Liverpool John Moores University Liverpool UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Howard T.","family":"Hurst","sequence":"additional","affiliation":[{"name":"Division of Sport, Exercise and Nutritional Science University of Central Lancashire Preston UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,8,2]]},"reference":[{"key":"e_1_2_7_2_1","first-page":"417","article-title":"Laboratory testing and field performance in BMX riders","volume":"10","author":"Bertucci W.","year":"2011","journal-title":"Journal of Sports Science and Medicine"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1519\/JSC.0b013e318234eb22"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1440\u20102440(99)80178\u20109"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1115\/1.1286678"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00421\u2010007\u20100498\u20104"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0021\u20109290(01)00182\u20108"},{"key":"e_1_2_7_8_1","first-page":"265","volume-title":"The Engineering of Sport","author":"Jones S.
