Class Experiences Flashcards
Room Considerations (9 total)
- Good ventilation and temp (65-85 degrees)
- Wooden/synthetic floor that absorbs shock and prevents medial-lateral foot motions
- Sufficient space
- Mirrors in front and sides of room
- Raised platform for instructor
- Control of lighting, temp, and sound
- Easy access to drinking water
- Easy access to equipment
- Aquatic temp: In between – Cardio = 83 degrees and Mind/Body = 90 degrees
Arthritis - Definition
inflammation of a joint
Tendinitis - Definition
inflammation of a tendon
prevention = proper shock absorbent floor
Sprains - Definition and Effected Areas of the body
a traumatic joint twist that results in stretching or tearing of the stabilizing connective tissues
Mainly involves ligaments or joint capsules, and causes discoloration, swelling, and pain
prevention = proper shock absorbent floor
Sweating and Core Temp - 4 total
- metabolic heat is produced during exercise
- Blood is brought to the skin to be cooled
- Sweat glands secret water which evaporates from the skin – cooling the blood
- Blood returns to reduce core temp
Core Temp Variation
In favorable conditions, core temp should only increase by 2-3 degrees
Exercising in Heat Effects
- HR is higher
- Total Heat load - external heat + internal heat
Hot and Humid Conditions reduce the body’s ability to lose heat and sweat CANNOT evaporate readily
Hyperthermia - Definition
abnormally high temperature
Heat Exhaustion - Definition and Result of
Most COMMON heat-related illness
Result of: intense exercise in hot, humid environment
Heat Stroke - Definition and Result of
a medical emergency that is the MOST SERIOUS heat-related illness
Result of: heat overload and impairment of the body’s ability to dissipate heat
Exercising in the Cold Affects on Body Temperature
-when the blood and skin temperature drops, mechanisms that conserve body heat and increase heat production are activated
Shivering Effect on Heat Production
Increases the body’s rate of heat production 4-5 times
Hypothermia - Definition
abnormally low body temperature
Blood Pressure - Definition and Measurement
- the pressure exerted by the blood on the walls of the arteries
- measured in millimeters of MERCURY (mmHg) with a sphygmomanometer
Hypertensive - Definition and mmHg
High blood pressure, or
the elevation of resting blood pressure above 140/90 mmHg.
Cold Air Effect on Exercise
-Made harder by WIND which increases CONVECTIVE heat loss
Convection - Definition
The transfer of heat through surrounding air or water molecules
Waters Effect on Exercise
- the body loses heat 4x faster in water
- the rate of loss increases when water is moving due to convection
Cold Weather Apparel Tips - 4 total
- Wear several layers of clothing
- hat is vital
- remove layers (high intensity)
- add layers (low intensity – warm-up, cool down, rest) - Allow adequate ventilation for sweat
- Prevent inner layer from soaking
- Wear garments that allow body to give off heat during exercise and retain heat when inactive
Fluid Intake - 2 Hours Before Exercise
17-20 oz (500-600 mL)
Fluid Intake - During
Every 10-20 mins – 7-10 oz (200-300 mL)
Fluid Intake - After exercise
16-24 oz per 1 lb lost (450-675 mL per 1/2 kg lost)
Cycling Apparel
- padded shorts
- cycling shoes (stiff soles)
Heat Environment Apparel
Cotton Materials
