Fig. 1.

Muscle temperature change from baseline (PRE) to post-warm-up (POST-WUP) and post-recovery (POST-REC) at 28, 18 and 8 mm depths. ^#Significant effect of depth on muscle temperature at both PRE and POST-WUP time points (p < 0.05). *Significant effect of warm-up on muscle temperature at all depths (p < 0.001). ^†Significant effect of passive warm-up on muscle temperature at all depth (p < 0.01). PRE and POST-WUP data are presented as the average of both legs. POST-REC muscle temperature is presented as the average of the perfused leg (BF) data collapsed over heating procedure WHOLE versus UPPER
