title: Effect of active warm-up duration on morning short-term maximal performance during Ramadan.
abstract: OBJECTIVE
  To examine the effect of active warm-up duration on short-term maximal performance assessed during Ramadan in the morning.
  
  
  METHODS
  Twelve healthy active men performed four Wingate tests for measurement of peak power and mean power before and during Ramadan at 09:00 a.m. The tests were performed on separate days, after either a 5-min or a 15-min warm-up. The warm-up consisted in pedaling at 50% of the power output obtained at the last stage of a submaximal multistage cycling test. Oral temperature was measured at rest and after warming-up. Furthermore, ratings of perceived exertion were obtained immediately after the Wingate test.
  
  
  RESULTS
  Oral temperature was higher after the 15-min warm-up than the 5-min warm-up throughout the study. Moreover, peak power and mean power were higher after the 15-min warm-up than the 5-min warm-up before Ramadan. However, during Ramadan, there was no significant difference between the two warm-up durations. In addition, ratings of perceived exertion were higher after the 15-min warm-up than the 5-min warm-up only during Ramadan.
  
  
  CONCLUSIONS
  There is no need to prolong the warm-up period before short-term maximal exercise performed during Ramadan in the morning.
