Background: Elevated temperature can be a source of fatigue. Local cooling can decrease perception of fatigue during a short term intense exercise.
Objective: To compare the effects of sole cooling and sole heating on fatigue during squatting.
Methods: Thirty male subjects with age = 22.1 ±1.8 yrs, height = 171.4 ± 5.6 cms and weight = 63.5 ±10.8 kgs were included in the study. Study design was experimental design with same subject undergoing testing in different conditions. Subjects performed four sets at 90 % of 10 repetition maximum (RM) squatting exercise to fatigue, with 3 minutes rest intervals. Exercise trials were performed in a counterbalanced order for 3 days, separated by at least 5 days: neutral intervention, sole heating and sole cooling. Heating and cooling were given to subjects in high sitting position with their feet on hot pack and cold pack respectively with feet supported on a foot stool. One way ANOVA along with Tukeys HSD was used to analyse the data.
Results: Rate of perceived exertion (R.P.E) during cooling intervention (2.8 ± 1.41) was significantly lower than heating intervention (3.2 ± 0.53) with p<0.05 and neutral intervention (3.4 ± 0.33) with p<0.05. Exercise volume, number of repetitions and EMG activity showed no statistically significant difference between cooling, neutral and heating intervention.
Conclusion: Sole cooling between sets of resisted squatting exercise resulted in decreased perception of fatigue.

In Simple Terms:
This study looked at how cooling or heating the bottoms of the feet affected fatigue during squatting. When feet were cooled between squat sets, people felt less tired, even though they didn’t actually do more reps or lift more weight. Cooling helped them feel better, but didn’t change performance.
