Which system is responsible for producing energy for movements longer than 90 seconds?
Aerobic system
What is the compound stored in muscles that is immediately available to produce movement?
Phosphocreatine (PCr)
Which nutrient is a source of immediate energy for muscle contraction?
Carbohydrates
What is the primary function of Adenosine triphosphate (ATP) in the body?
Energy currency for cellular processes
What is the primary energy system used for brisk walking?
Aerobic System
Which product is broken down into ATP through a process called glycolysis in the Lactic Acid System?
Carbohydrates
What is the by-product formed during the process of glycolysis in the Lactic Acid System?
Lactate
Which energy system provides energy quickly but not over a long duration?
Lactic Acid System
What causes the immediate anaerobic energy transfer from the hydrolysis of intramuscular high-energy phosphates and glycolysis?
Oxygen Debt
What does exceptional endurance relate to according to the text?
High capacity of the central circulation to deliver oxygen to working muscles and a high capacity of the exercised muscle to use the available oxygen
What is the main reason for the rapid progress to steady-rate oxygen consumption in endurance training?
Decreased anaerobic energy transfer
Why do sprint power athletes not experience the same decrease in oxygen deficit as endurance-trained individuals?
Higher reliance on anaerobic energy transfer
Which nutrient is referred to as a 'macronutrient' due to its need in relatively large quantities for energy production in both anaerobic and aerobic activity?
Carbohydrates
What type of exercise is recommended for improving the ATP-PCr system?
Explosive movements like box jumps
Why are saturated fats associated with a greater risk of various diseases?
They promote inflammation and cardiovascular issues
What is the main limitation of the anaerobic pathways despite their ability to regenerate ATP at high rates?
Limited oxygen availability
In contrast to the anaerobic pathways, what is the main limitation of the aerobic system?
Inability to regenerate ATP quickly
What is the main characteristic of physical activities in relation to the 3 energy-supplying processes?
They transition smoothly between all three energy systems
