05 - Metabolic Energy System Training Flashcards
What is the most misunderstood and underrated form of training?
cardiorespiratory endurance
What energy systems are training for endurance training?
aerobic and anaerobic
What is Pulmonary ventilation?
The process which brings oxygen from the air, across the alveolar membrane, and into the blood to be carried by hemoglobin.
What is Cardiac output?
The amount of blood the heart pumps per minute.
What is Stroke volume?
The amount of blood pumped with each contraction of the ventricles.
What is the energy currency of the body?
Adenosine triphosphate ATP
What are the two ways ATP can be produced and which method is more efficient?
ATP is produced aerobically (with oxygen) and anaerobically (without oxygen). Of these two methods, the most efficient, by far, is the aerobic system
What is a normal HR and what is a HR from an athlete
70, 40
What happens to the heart with aerobic exercise?
It becomes larger and pumps more blood per beat (more efficient)
The movement of oxygen and carbon dioxide into and out of the circulatory system takes place through _______?
diffusion
Lung diffusion is your ability to pass oxygen into the blood from the air sacs of the lungs, and pass carbon dioxide (CO2) back into the lungs from the blood.
What is systolic blood pressure reading?
The pressure on the vascular wall (during contraction)
What is the diastolic blood pressure reading?
relaxation phase of the cardiac cycle
How are cardiac output and oxygen consumption related?
linear. As cardiac output increases, oxygen consumption will increase as well.
What is the main central cardiovascular adaptation?
change in stroke volume (pump more blood per beat)
Heart rate can change from rest to maximum by around a factor of _, while the stroke volume changes by only a factor of _?
3 (i.e., from 60 to 180 bpm)
1.7 (from 70 to 120 mL)
Resting cardiac output is typically around _ L/min at rest and about __-__ L/min during maximum exercise, but for the aerobic elite (e.g., cross country skiers, rowers, cyclists) it may be over __ L/min.
6 and 20–25
40ML
The chemical reactions that transform energy in the cells of the body are collectively known as ________.
metabolism
If all ATP was placed into a container, how much would there be?
a shot glass or small juice glass.
During light and low intensity cardio, what energy system is used by the body and what body systems are used?
Oxadative
Respiratory, cardiovascular, muscular and endocrine
The aerobic pathways provide the major supply of energy to all cells of the body through the metabolism of circulating ___, _____ and _____.
glucose, stored fats, and stored carbohydrates
During light and low intensity cardio, what energy system is used by the body and what body systems are used?
Oxidative
Respiratory, cardiovascular, muscular and endocrine
What energy source produces the most APT?
fat that are 9 cals per gram while carbs are 4 grams.
What are the waste by products of creating ATP?
water and CO2.
Anaerobic metabolism is the ability of the body to produce energy by metabolizing carbohydrates in the absence of _______.
oxygen
