Abstract:
The relationship between muscle recruitment and temperature was determined
using water to create a temperature-controlled environment and BioPac®
to measure the force and EMG output of the dorsal interosseous muscle.
By plotting integrated EMG versus force developed, muscle recruitment was
obtained. This was plotted over the range of temperatures from 10ºC
to 45ºC. It was found that, on average, the integrated EMG/gram was
0.0347 ± 0.011 mV at 10ºC, 0.045 ± 0.0233 mV at 25ºC,
and 0.0703 ± 0.018 mV at 45ºC (95% confidence intervals). Paired
t-tests (p<0.05) showed that the muscle recruitment at each temperature
was significantly different from the others. These results are similar
to those of the 1999 study by Wade, et al. that muscle recruitment and
temperature are directly proportional.1
