The primary purpose of the present study was to compare the effectiveness
of two forms of hand heating and to discuss specific trends that relate finger
dexterity performance to variables such as finger skin temperature
(T fing ), finger blood flow
( fing ), forearm skin temperature
(T fsk ), forearm muscle temperature (T fmus ), mean
weighted body skin temperature
( sk ), and change in body heat
content ( Hb). These variables along with rate of body heat storage, toe
skin temperature, and change in rectal temperature were measured during direct
and indirect hand heating. Direct hand heating involved the use of
electrically heated gloves to keep the fingers warm (heated gloves condition),
whereas indirect hand heating involved warming the fingers indirectly by
actively heating the torso with an electrically heated vest (heated vest
condition). Seven men (age 35.6 ± 5.6 yr) were subjected to each method
of hand heating while they sat in a chair for 3 h during exposure to -25°C
air. fing was significantly
( P < 0.05) higher during the heated vest condition compared with
the heated gloves condition (234 ± 28 and 33 ± 4 perfusion
units, respectively), despite a similar T fing (which ranged between
28 and 35°C during the 3-h exposure). Despite the difference in
fing , there was no significant
difference in finger dexterity performance. Therefore, finger dexterity can be
maintained with direct hand heating despite a low
fing . H b ,
sk , and T fmus reached a
low of -472 ± 18 kJ, 28.5 ± 0.3°C, and 29.8 ±
0.5°C, respectively, during the heated gloves condition, but the values
were not low enough to affect finger dexterity.

The primary purpose of the present study was to compare the effectiveness
of two forms of hand heating and to discuss specific trends that relate finger
dexterity performance to variables such as finger skin temperature
(T fing ), finger blood flow
( fing ), forearm skin temperature
(T fsk ), forearm muscle temperature (T fmus ), mean
weighted body skin temperature
( sk ), and change in body heat
content ( Hb). These variables along with rate of body heat storage, toe
skin temperature, and change in rectal temperature were measured during direct
and indirect hand heating. Direct hand heating involved the use of
electrically heated gloves to keep the fingers warm (heated gloves condition),
whereas indirect hand heating involved warming the fingers indirectly by
actively heating the torso with an electrically heated vest (heated vest
condition). Seven men (age 35.6 ± 5.6 yr) were subjected to each method
of hand heating while they sat in a chair for 3 h during exposure to -25°C
air. fing was significantly
( P < 0.05) higher during the heated vest condition compared with
the heated gloves condition (234 ± 28 and 33 ± 4 perfusion
units, respectively), despite a similar T fing (which ranged between
28 and 35°C during the 3-h exposure). Despite the difference in
fing , there was no significant
difference in finger dexterity performance. Therefore, finger dexterity can be
maintained with direct hand heating despite a low
fing . H b ,
sk , and T fmus reached a
low of -472 ± 18 kJ, 28.5 ± 0.3°C, and 29.8 ±
0.5°C, respectively, during the heated gloves condition, but the values
were not low enough to affect finger dexterity.
