Prelab 4: Environmental Conditions and Modalities

Prelab 4: Environmental Conditions and Modalities Answer the participation activity questions below prior to attending lab. 1. List the eight physiological responses of cryotherapy. a. Muscle Spasm (decreases) b. Pain perception (decreases) c. Blood flow (decreases up to 10 minutes) d. Metabolic rate (decreases) e. Collagen elasticity (decreases) f. Joint stiffness (increases) g. Capillary permeability (decreases) h. Edema (decreases) 2. List the eight physiological responses to thermotherapy. a. Muscle spasms (decreases) b. Pain perception (decreases) c. Metabolic blood flow (increases) d. Collagen elasticity (increases) e. Joint stiffness (decreases) f. Capillary permeability (increases) g. Edema (increases) h. Metabolic Rate (increase) 3. Utilizing the GCU library, peer-reviewed literature from reputable journals, or other reputable resources (e.g., textbook), identify and describe two valid and reliable methods for assessing hydration status in competitive athletes. Be sure to cite your references. a. “Collegiate athletes who were injury free and could exercise > 75% of their maximum heart rate for a minimum of 45 minutes “ The reason that these athletes were used is because they were injury free and were able to physically push themselves with a subsequent amount of effort Ayotte, D., & Corcoran, M. P. (2018). Individualized hydration plans improve performance outcomes for collegiate athletes engaging in in-season training. Journal of the International Society of Sports Nutrition, 15(1), N.PAG. Retrieved from https://search-ebscohostcom.lopes.idm.oclc.org/login.aspx?direct=true&db=s3h&AN=129966581&site=eds-live&scope=site b. The environment should be taken into consideration when assessing hydration in competitive athletes because different environments produce a different sweat rate and require an athlete to drink certain amount of water.

Utilize Chapter 6 in Principles of Athletic Training: A Competency-Based Approach to answer the following questions. 1. List and describe five ways heat can be gained or lost. a. Metabolic Heat Production: The metabolism causes an increase in body heat based on the intensity of the physical activity b. Evaporative Heat Loss: The core temperature of the body increases and the body triggers the sweat glands in the skin to bring additional moisture to the surface of the skin c. Radiant Heat Exchange: Radiant heat from the sunshine causes an increase in body temperature d. Convective Heat Exchange: When a mass of either water or air moves around an individual e. Conductive Heat Exchange: Physical contact with other objects results in a heat loss or a heat gain 2. Describe uses for a sling psychrometer and the data that can be obtained from its use. A sling psychrometer is an instrument that measures the relative humidity and dew point in an area. It has two thermometers: a wet bulb and a dry bulb. The wet bulb has a cotton wick over the bulb of the thermometer, which is moistened with room temperature water. The dry bulb is a thermometer 2
