Resumo: The aims of the present study were to assess the reliability of long sprint cycling performance in a group of recreationally trained cyclists and to provide thresholds for changes in performance for this particular group of subjects in repeated measures designs through a scale of magnitudes. Repeatability of mean power output during a 1-min cycling time trial was assessed in a group of 15 recreationally trained cyclists (26 ± 5, years, 176 ± 5 cm, 78 ± 8 kg). They were tested on separate days, approximately one week apart. The test and retest values for the whole group of cyclists were 7.0 ± 0.5 W/kg and 6.9 ± 0.6 W/kg (systematic change and 90% confidence limits of -1.0% ± 1.1%). Our results indicated good test-retest reproducibility (typical error of 1.8%, 90% confidence limits of 1.4% to 2.6%; intraclass correlation coefficient of 0.96, confidence limits of 0.91 to 0.99), but suggested a reduction of mean power for the “slower” subjects on retest (-2.0%, 90% confidence limits of ±1.8%). If not monitored, this systematic decrease could interfere in results of studies utilizing groups with similar performance levels, particularly investigating strategies to improve performance in sprint cycling exercises around 1 min. The thresholds for moderate, large, very large and extremely large effects for mean power output on long sprint cycling performance are about 0.4%, 1.3%, 2.3%, 3.6%, and 5.8%, respectively.

A reprodutibilidade da potência média durante um contrarrelógio de 1-min foi avaliada em um grupo de 15 ciclistas recreativamente treinados (26 ± 5 anos, 176 ± 5 cm, 78 ± 8 kg). Eles foram avaliados em dias separados, com aproximadamente uma semana de intervalo. Os valores de teste-reteste no contrarrelógio de 1-min para o grupo inteiro foram 7,0 ± 0,5 W/kg and 6,9 ± 0,6 W/kg (mudança sistemática e limite de confiança de 90% de -1,0% ± 1,2%). Nossos resultados indicam boa reprodutibilidade teste-reteste (erro típico de 1,8%, limite de confiança de 90% de 1,4% para 2,6%; coeficiente de correlação intraclasse de 0,96, limite de confiança de 90% de 0,91 para 0,99), mas sugeriu uma redução da média de potência para os sujeitos “mais lentos” no reteste (-2,0%, limite de confiança de 90% de ±1,8%). Se não monitorada, esta queda sistemática na potência pode interferir nos resultados de estudos utilizando grupos com níveis similares de desempenho, particularmente investigando estratégias para melhorar o desempenho em sprints com duração próxima a 1 min. Os limiares para efeitos moderado, grande, muito grande e extremamente grande para média da potência em sprint longo no ciclismo são aproximadamente 0,4%, 1,3%, 2,3%, 3,6% e 5,8%, respectivamente. Universidade Federal de Santa Catarina.
