Physical fitness is a general term to describe ability to perform physical work. Physical work requires what 4 things?
- Cardiorespiratory function
- Muscular strength
- Muscular endurance
- Musculoskeletal flexibility
Fitness Levels:
- A continuum which can range from ____ to _______
- Based on energy __________ during a bout of physical work
- Often based on direct or indirect measurement of body’s maximum oxygen consumption (_______)
- poor to superior
- expenditure
- VO2 max
- What is a VO2 max?
- What are some factors that influence VO2 max?
VO2 max = maximum amount of O2 consumed/minute when the individual has reached maximum effort
Influenced by:
- Age
- Gender
- Heredity
- Inactivity
- Disease
What are 4 common clinical ways to assess aerobic fitness?
- Modified Bruce Protocol
- 2MWT
- 6MWT
- Cycle Ergometer Test
What is endurance?
The ability to work for prolonged periods of time and the ability to resist fatigue.
What is the difference between muscular endurance and cardiovascular endurance?
Muscular Endurance
-Ability of an isolated muscle group to perform repeated contractions over a period of time
Cardiovascular Endurance
-Ability to perform large muscle dynamic exercises.
What is aerobic conditioning?
Improving the energy utilization of the muscle through an exercise program.
With aerobic conditioning, improvement in energy utilization is a direct result of increased levels of what 3 things?
- Oxidative enzymes in the muscles
- Mitochondrial density and size
- Muscle fiber capillary supply
- What is the goal of aerobic exercise?
- Important to remember the _____ and ______ principles.
- Adaptation, which results in increased efficiency of the CV system and active muscles.
- FITT and SAID
With training, performance improves as the body adapts so that the same amount of work can be performed at a _______ physiological cost.
lower
- Adaptation is dependent on the ability of the _________ to change and the training stimulus _________.
- Does a person with a low level of fitness have more potential to improve than one who has a high level of fitness?
- organism, threshold
- Yes
Deconditioning occurs with prolonged _________/ ________ lifestyle. Decrease occurs ______.
- prolonged bed rest/sedentary lifestyle
- rapidly (maximum O2 consumption, CO (SV), muscular strength)
What all does bed rest decrease?
- Muscle mass
- Strength
- CV function
- Blood volume
- Plasma volume
- Orthostatic tolerance
- Exercise tolerance
- BMD
_______ and _______ of activity determine what energy metabolic system contributes.
Duration and intensity

- Ability to metabolize oxygen related to _______ and ________ of mitochondria
- System predominantly used after __ minutes of exercise and beyond
- glycogen, fats, and proteins
- aerobic
- mitochondria
- number and concentration
- 2 minutes
Effective endurance training for any population must produce a __________ or _________ response.
conditioning or CV response
What are the 4 cardiac responses to endurance training?
- Increased myocardial contractility
- Increased cardiac output
- Increased HR
- Increase SBP
What are the vascular responses to endurance training?
- Generalize vasoconstriction shunting arterial blood to working areas.
- Veins of working and nonworking muscles constricted to increase cardiac return.
- The muscles trained develops a greater oxidative capacity with an increase in blood flow to the area.
What are the parts of the FITT principle?
- Frequency
- Interval
- Time
- Type
Training produces _________ and/or __________ adaptation. Training for a particular sport or event is dependent on the ___________ principle.
- cardiovascular and/or muscular
- specificity
