We hypothesized that maximal aerobic capacity and skating velocity at LT would increase as the season progressed. Sixteen Division I college hockey players performed a graded exercise skating protocol to fatigue at 3 different times (pre-, mid-, and postseason). Subjects skated for 80\u00a0s during each stage, followed by 40\u00a0s of rest to allow for blood lactate sampling. Velocity at LT was similar during preseason (4.44\u00a0\u00b1 0.08\u00a0m\u00b7s<jats:sup>\u20131<\/jats:sup>) and postseason (4.52\u00a0\u00b1 0.05\u00a0m\u00b7s<jats:sup>\u20131<\/jats:sup>) testing, but was significantly elevated at midseason (4.70\u00a0\u00b1 0.08\u00a0m\u00b7s<jats:sup>\u20131<\/jats:sup>; p\u00a0&lt; 0.01), compared with preseason. In contrast, LT as a percentage of maximal heart rate (HR<jats:sub>max<\/jats:sub>) was unchanged throughout the season. HR<jats:sub>max<\/jats:sub> remained constant throughout the season, at approximately 190\u00a0beats\u00b7min<jats:sup>\u20131<\/jats:sup>. Preseason maximal aerobic capacity (48.7\u00a0\u00b1 0.8\u00a0mL\u00b7kg<jats:sup>\u20131<\/jats:sup>\u00b7min<jats:sup>\u20131<\/jats:sup>) was significantly higher than that at postseason (45.0\u00a0\u00b1 1.1\u00a0mL\u00b7kg<jats:sup>\u20131<\/jats:sup>\u00b7min<jats:sup>\u20131<\/jats:sup>; p\u00a0&lt; 0.01). In conclusion, skating velocity at LT improved from pre- to midseason, but this adaptation was not maintained at postseason. Additionally, maximal aerobic capacity was reduced from pre- to postseason. These findings suggest a need for aerobic training throughout the college hockey season. <\/jats:p>","DOI":"10.1139\/h08-107","type":"journal-article","created":{"date-parts":[[2008,12,15]],"date-time":"2008-12-15T16:03:36Z","timestamp":1229357016000},"page":"1165-1171","source":"Crossref","is-referenced-by-count":19,"title":["Sport-specific assessment of lactate threshold and aerobic capacity throughout a collegiate hockey season"],"prefix":"10.1139","volume":"33","author":[{"given":"John J.","family":"Durocher","sequence":"first","affiliation":[{"name":"Department of Exercise Science, Health and Physical Education, Michigan Technological University, 1400 Townsend Drive, Houghton, MI\u00a049931, USA"},{"name":"Portage Sports Medicine Institute, Portage Health, 500 Campus Drive, Hancock, MI\u00a049930, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Darin T.","family":"Leetun","sequence":"additional","affiliation":[{"name":"Department of Exercise Science, Health and Physical Education, Michigan Technological University, 1400 Townsend Drive, Houghton, MI\u00a049931, USA"},{"name":"Portage Sports Medicine Institute, Portage Health, 500 Campus Drive, Hancock, MI\u00a049930, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jason R.","family":"Carter","sequence":"additional","affiliation":[{"name":"Department of Exercise Science, Health and Physical Education, Michigan Technological University, 1400 Townsend Drive, Houghton, MI\u00a049931, USA"},{"name":"Portage Sports Medicine Institute, Portage Health, 500 Campus Drive, Hancock, MI\u00a049930, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"155","reference":[{"key":"rg1\/ref1","first-page":"188","volume":"69","author":"Agre J.C.","year":"1988","journal-title":"Arch.
