The purpose of this study was to investigate relationships between hand morphological factors and hand heat flow during active and passive heating. A total of 13 males and 9 females (24.4±2.3 y in age, 168.5±10.3 cm in height, 68.2±14.5 kg in weight, 1.81 ± 0.23 m2 in body surface area) participated in the following four heating conditions: exercises using a treadmill at 8 km·h−1 for males and 6 km·h−1 for females (60 min), cycle ergometer at 55 watts for males and 40 watts for females (50 rpm, 60 min), and arm ergometer at 20 watts for males and 10 watts for females (50 rpm, 60 min); and leg immersion at 42oC water (60 min). The results showed that hand heat flow was significantly related to hand volume (r =0.438, P = 0.041), but not hand surface area. The relationship was significant for males (r = 0.641, P = 0.018), not for females. Among the four heating conditions, hand heat flow had the highest value for the leg exercise. There were no relationships between hand heat flow and hand temperature, except for the leg immersion (r = 0.395, P = 0.069). These results indicate that hand volume is a significant factor to estimate hand heat flow during active or passive heating, which is marked for males rather than for females. In addition, hand heat flow was obtained more stably during leg exercise or leg immersion, which was characterized by fewer hand movements compared to the treadmill exercise or arm exercise conditions.

This study investigated the combined effects of wrist compression and hand cooling on cutaneous vasoconstriction of the hands to develop chemotherapy gloves that alleviate side-effects of anti-cancer treatments. Eight healthy young females (23 ± 3 y in age, 162 ± 4 cm in height, 60 ± 8 kg in weight, 22.6 ± 3.0 kg·m-2 in body mass index, 29.0 ± 6.6 % body fat) participated in the following three experimental conditions: cooling only with 14oC (CO), cooling & intermittent compression (CIC), and cooling & continuous compression (CCC). The results showed 1) no significant differences in finger skin blood flow(%) or finger skin temperature among the three conditions, 2) no significant difference in hand skin temperature between the CO and CCC or CIC conditions, and 3) no significant differences in overall thermal sensation or thermal comfort among the three conditions. However, subjects felt more wrist and hand pressure and tingle sensations in the CIC (pressure phase) and CCC conditions than in the CO condition (P<0.001). In conclusion, we did not find any synergistic effects on hand skin vasoconstriction from adding wrist compression to hand cooling, and the pressure and tingling sensations were deteriorated by adding the compression band. Therefore, we suggest cooling the hands at 14oC during cancer treatments, rather than adding compression with cooling.
