Q

Relationship between cellular metabolism and the production of heat in the body.

A

Heat produced by all active tissues in body, when muscles contracts, and ATP is converted to ADP.

20-25% of energy stored in ATP is used in the muscle contraction, and 80% of energy released as heat.

32
Q

Ergogenic aids

A

Anything that aids in improving an athletes performance. Whether that be a substance, phenomenon or device.

33
Q

How does the body Thermoregulate in hot and cold environments?

A

Conduction, convection, radiation, evaporation

34
Q

Conduction

A

Heat generated deep in your body can be conducted through tissue to the surface and to the clothing/air in direct contact with skin. Rate of conductive heat loss depends on the temperature gradient between skin and surrounding surfaces.

35
Q

Convection

A

Moving heat from one place to another by the motion of air or water movement. If cooler air continually replaces warmer air around the body (windy day) heat loss increases.

36
Q

Radiation

A

The transfer of energy waves that are sent out from one object and absorbed by another. The body absorbs radiant heat energy when the temperature of the environment is higher than skin temperature.

37
Q

Evaporation

A

As the environment temperature increases, conduction convection and radiation decrease their effectiveness for heat loss. When this happens, evaporative cooling (conversion of sweat from liquid to water vapor) is the main form of heat loss.

38
Q

Significance of humidity and wind in relation to body heat loss.

A

When the environment temperature is above skin temperature, evaporative heat exchange will account for heat loss. Dry air receives water vapor more easily. When humidity is high, the air already contains water and the vaporization of sweat is lower.

39
Q

How should an athlete acclimatize to heat stress?

A
  • exercise in the hot environment, not merely exposure
  • for at least 10-14 days before competition
  • better matching of thirst to body’s water needs
  • increased total body water
  • 90-100 minutes per day but reach this amount of time gradually by increasing duration and intensity.
40
Q

Physiological and metabolic adaptations that occur with heat acclimatization.

A
  • increased plasma volume
  • earlier onset of sweating
  • lower core body temperature
  • more dilute sweat composition (electrolyte loss reduced)
  • decreased psychological perception of effort
  • maintain submaximal exercise for longer periods of time
  • benefits remain for a week after moving to a cooler place but 75% are lost three weeks after heat exposure
41
Q

Peripheral vasoconstriction

A

Constricts/narrows blood vessels leading to the periphery.
Reduces blood flow to shell, reducing heat loss through skin.
First line of defense against decreasing core temperature in cold climate.

42
Q

Non-shivering thermogenesis

A

Stimulates the metabolism by the sympathetic nervous system to generate more metabolic heat.

43
Q

Shivering

A

Rapid, involuntary cycle of muscle contraction/relaxation of skeletal muscles (generates heat from ATP system)

44
Q

Importance of windchill in relation to body heat loss

A

The body radiates heat to the surrounding air which it attempts to warm up, as well as warming up the body. If this air is constantly moving because of wind then the air cannot heat up, and the body simply loses heat without any benefit. With convection, the body attempts to heat the air surrounding to create a bubble of warm air. With winds the air cannot heat up.

45
Q

Explain why swimming in cold water presents a challenge to the body’s ability to Thermoregulate.

A

Water is cold, so the body is forced to send blood away from the core to extremities to supply oxygen to the working muscles. However the vasodilation of these blood vessels increases sweating and loss of heat. If the water is cold, the body needs to employ vasoconstriction to reduce heat loss. Also as the cold water moves by the body, convection, heat is exchanged.

46
Q

Physiological response to exercise in the cold.

A

Vasoconstriction to the periphery.
Non shivering thermogenesis
Shivering

47
Q

Health risks of exercising in the cold.

A

Frostbite- cells freeze and die, go black, numb

Hypothermia- when the core body temperature is lower than normal.

48
Q

Precautions that should be taken when exercising in the cold

A

Proper warm up.
Frequent stretching.
Appropriate clothing layers to protect and insulate.

49
Q

Placebo effect

A

Positive effect that cannot be attributed to the properties of the placebo itself but due to the persons belief that the placebo works.

50
Q

Explain why body surface area/body mass ratio is important for heat preservation

A

Larger body shape = smaller surface area (less susceptible to hypothermia)
Smaller body shape = larger surface area (creates greater heat loss and more susceptibility to hypothermia)
