Cumulative pre-cooling methods do not enhance cycling performance in tropical climate

p<0.0001, ηp2 = 0.81] was observed. There was no effect of either Condition [F(2,10) = 1.00, p = 0.40, ηp2 = 0.17] or the Condition×Period interaction [F(18,90) = 1.14, p = 0.33, ηp2 = 0.19]. Rating of perceived exertion During the warm-up with pre-cooling strategies (Table 2), a Friedman ANOVA indicated sig- nificant differences between RPE’ measures from T5 to T30 for ICE-VEST (Friedman Fig 1.
