AEA Water - Chapter 5 EXAMS

Intensity of exercise (rest, submaximal exercise, or maximal exercise) Dunking (temporary submersion of the head & face) Individual participant factors (age, sex, disease, & so on) True - Water cools the body faster than air and most participants don't experience the negative effects of heat when exercising vigorously in the pool. False - Because the water temperature is lower than body temperature aquatic instructors to not need to be concerned with participants overheating or chilling. In cooler water, (below 78 degrees F) what physiological responses in the body are altered? - Metabolic and heart rate slow down. Circulatory functions become slower. The majority of body fluids remain in the trunk area to keep essential organs warm and functioning. Reduced circulation to the extremities causes muscles to remain cold and inflexible, increasing risk of injury. Ischemia will occur in the muscles of the extremities because of reduced blood flow resulting in cramping, notably in the calf muscle. What are the physiological effects to the body when an individual participates in moderate to vigorous exercise in near or above 90 degrees F.? - Heat dissipation is hindered and the body is not efficiently cooled
