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

Fig 3. Comparison of the mean heart rate between conditions. NO-VEST: without vest, ICE-VEST: cooling water vest and MEN-VEST: cooling menthol vest during the warm-up (A) and the cycling performance (B). The error bars represent standard deviation from the mean. Significant differences for time effects have been marked as follows: *p<0.05. https://doi.org/10.1371/journal.pone.0291951.g003 Table 2.
