Energy Systems & Interplay
ATP is called the body's energy currency for this reason
Muscle contractions
HR x SV
Cardiac Output
Fluid taken to rehydrate
Water
The fatigue experienced by athletes around the 90min mark of an event
Glycogen depeletion
This anaerobic pathway breaks down glucose to produce ATP and lactate
Anaerobic glycolysis system
More blood sent to muscle instead of non-essential organs
Redistribution of blood flow
Ingestion of food containing ........... will increase muscle rebuild and repair
Protein
What scale can athletes use to determine fatigue levels
RPE
Using multiple energy systems together in activity
Energy interplay
Air volume moved per minute
Ventilation
The process of intaking more fuel 24-48hrs before an event to enhance performance
Carbohydrate loading
Two of the fatigue mechanisms that impact long endurance events
Fuel depletion and Thermoregulatory fatigue
The dominant system in a marathon
Aerobic energy system
Extra oxygen consumed post-exercise
EPOC
Identify the type and duration of event in which athletes may benefit from carbohydrate loading
Marathon - 3hr
Event 90+
Identify three factors that impact the loss of fluid for an athlete
Environment, Sweat Rate, Intensity
Fatigue in anaerobic efforts is often caused by the by-product
Lactact or H+ Ions
This muscular response relates to the all or nothing principle
Muscle fibre recruitment
The co-ingestion of these suggest that it will enhance the rate of recovery
CHO / Water or CHO / Protein
Explain how an athlete can delay fatigue during high intensity efforts
Nutrition and Water
