Description Usage Details Source Examples
This data set contains the results of an experiment comparing the efficacy of different forms of dry ice application in reducing the temperature of the calf muscle.

The 12 subjects in this study came three times, at
least four days apart, and received one of three ice treatments (cubed ice, crushed
ice, or ice mixed with water). In each case, the ice was prepared in a plastic bag
and applied dry to the subjects calf muscle.
The temperature measurements were taken on the skin surface and inside the
calf muscle (via a 4 cm long probe) every 30 seconds for 20 minutes prior to icing,
for 20 minutes during icing, and for 2 hours after the ice had been removed.
The temperature measurements are stored in variables that begin with B
(baseline),
T
(treatment), or R
(recovery) followed by a numerical code for the elapsed
time formed by concatenating the number of minutes and seconds. For example,
R1230
contains the temperatures 12 minutes and 30 seconds after the ice had been
removed.
