Brief Summary:
The purpose of this study is to test if temperature homeostasis in football players can be improved by circulating cool dry air underneath shoulder pads between periods of intense physical activity
Detailed Description:
The purpose of this study is to test if temperature homeostasis in football players can be improved by circulating cool dry air underneath shoulder pads between periods of intense physical activity To assess the efficacy of this intervention several dependent variables will be tested core body temperature skin temperature infrared skin temperature heart rate sweating rate urine color urine specific gravity physiological strain index visual analog thirst rate of perceived exertion thermal sensation scale and fluid intake The two independent variables test variables are treatment which has two levels Control - no air blown under the shoulder pads COOL - cool dry air blown under the shoulder pads and time pre-exercise and post-exercise cycles rest break and recovery
Specific Aim 1 To assess differences in physiological parameters when cooled dry air is blown under football shoulder pads as a means of cooling football players between periods of exercise and after exercise Limited research is available to demonstrate the efficacy of cooling methods alternated with vigorous exercise Football players are at particular risk for heat-related illness because they frequently practice and compete in hot humid conditions in uniforms that limit the bodys natural thermoregulation To study this specific aim three hypotheses will be addressed during the data collection process of this investigation 1 a significantly lower increase in core body temperature heart rate skin temperature and infrared skin temperature will be noted during the COOL testing sessions as compared to the Control sessions 2 significantly lower measurements of urine color urine specific gravity and sweat rate will be noted in the COOL testing sessions as compared to the Control sessions and 3 significant associations will be noted between core body temperature and infrared temperature during both testing sessions
Specific Aim 2 To assess differences in subjective ratings of exertion and heat stress during and after exercise sessions when cooled dry air is blown under football shoulder pads as compared to no air during rest breaks between the exercise bouts The rationale behind Specific Aim 2 is that the cooling method COOL will aid in improving the bodys blunted cooling mechanisms The sensation of the cool dry air will be more prominent than the sensation of warmth during the COOL trials the decrease in physiological strain and the decrease in core body temperature will cause the subject to experience lower perceived exertion thus subjects subjective response to exertion in subsequent exercise cycles will be decreased One hypothesis will be addressed related to this specific aim cool dry air blown under football shoulder pads COOL as a cooling method between exercise bouts will significantly lower physiological strain index score visual analog thirst score rate of perceived exertion and thermal sensation score as compared to no cool dry air being blown under the shoulder pads Control
