Study Notes
Exercise Physiology: Factors Affecting Performance and Thermoregulation
- Lactic acid build-up in speed skating can have controversial effects, with H+ ions having detrimental effects and lactate potentially being a fuel source.
- Carbohydrate supercompensation involves depleting glycogen stores and then consuming carbohydrates to double the amount of stored glycogen.
- Sodium bicarbonate can be used to buffer H+ ions, improving performance and avoiding fatigue, but excessive use may cause gastrointestinal issues.
- Caffeine can increase fatty acid utilization and has upper limits set by the IOC for urine concentration.
- Muscle soreness, including acute soreness and delayed-onset muscle soreness, can be attributed to factors such as inflammation, muscle damage, and increased Ca2+ levels.
- The Bible verses cited suggest a mental aspect in fighting fatigue during exercise.
- Thermoregulation involves maintaining a relatively constant body temperature despite external environmental changes, with core and skin temperature measurements being key factors.
- Heat exchange in thermoregulation is influenced by factors such as gradient, humidity, wind, sunlight, clothing, and playing ground.
- Heat stress and strain, hyperthermia, and acclimatization are important concepts related to thermoregulation.
- Factors affecting thermoregulation include hydration, body composition, acclimatization, and aging, with dehydration impairing performance if fluids are not replaced quickly.
- Men and women generally have similar responses for thermoregulation, except during the menstrual cycle and in terms of evaporation and conduction/convection.
- Aging affects thermoregulation due to changes in muscle mass, surface area-mass ratio, and cardiac output, with old people having less plasma volume and being more susceptible to heat illness.
