摘要:

The threat of head injury in ice hockey at the professional, collegiate, and high school levels is still evident even after repeated attempts to introduce head protection. One area in which head protection is not mandatory is that of college intramural ice hockey. This study reports on the effect of introducing a new type of ice hockey helmet into college intramural ice hockey games. The effect of this new helmet to reduce injuries is demonstrated by the significant reduction in head injury rate from 8.3 head injuries per 100 games played to 3.8 head injuries per 100 games.

摘要:

On the first and last of 3 consecutive days, 10 normally active male subjects executed a series of 25 maximal grip contractions at 5 second intervals and 10 maximal contractions at 1 minute intervals. Each contraction was approximately 1 second in duration. Exercise was preceded by a 10 minute rest. An intramuscular thermocouple was inserted on the second day and remained in place for the experiment on the third day. Thermocouple insertion was followed by an immediate reactive increase in muscle temperature. Grip strength was not affected by the thermocouple. The largest strength and temperature measurements were observed coincidentally.
