| ABSTRACT | |||
| This study investigated the between trial variation of thermoregulatory
measures during a heat acclimation protocol. Eight 14-16 y old boys completed
three bouts of 20-min cycling at 45 % peak VO2 in a hot environment
(35.1 ± 1.2 °C and 46. 4 ± 1.0 % relative humidity) on two occasions separated
by a minimum of 24 h. Reliability was assessed through analysis of within-subject
variation, the change in the mean, and retest correlation for measurements
of aural temperature (Tau), mean skin temperature (Tsk), heart rate (HR)
and oxygen uptake (VO2). Between trial differences were low for
Tau, Tskbout1, Tskbout2and3 and HR with coefficients of variation 0.6 %,
1.5 %, 0.5 % and 4.0 %, respectively. The results demonstrate good reliability
that will allow future investigators to precisely determine the extent of
heat acclimation protocols in relation to the measurement error.
Key words: Reliability, heat acclimation, aural temperature, mean skin temperature. |
