PT midterm Flashcards
o Chronic Effects of Exercise
Increase Life Expectancy Increase Stroke Volume Increase Bone Density Increase Metabolic Increase Heart Size Increase HDL Increase VO2 Max Decrease Body Fat Decrease Resting Blood Pressure Increase Lean Body Mass Increase Blood Volume
- Acute Effects of Exercise
o Increase Heart Rate o Increase Skin temperature o Increase Hormones o Increase Intake O2 o Increase Stroke Volume o Increase Cardiac output o Increase Vo2 difference o Increase Sweat Rate
Principles of exercise program design
- Specificity of training
- Overload
- Progression
- Initial values
- Diminishing returns
- Inter individual variability
- Reversibility
Progression:
a method of increasing duration, intensity, or frequency gradually over a period of time.
Stages of Progression
o Initial Conditioning: 1-6 Weeks Goal = 55-60% HRR for 30 min o Improvement: 4-8 months Increase duration and frequency before intensity o Maintenance: Lifetime commitment Vary activities
• Strategies to increase exercise adherence
o Have incentives or rewards to treat yourself after exercise
o Working out with peers
o Perform exercises you enjoy
o Go to a facility or an environment that you enjoy
- Precontemplation
person isn’t thinking about it
contemplation
person starts thinking about it
preparation
getting ready to change, they signed up for a gym
Action
person has begun working out and has a workout plan
Maintenance
person has kept up with exercise and makes it a consistent daily routine
ACSM guidelinesfor cardiorespirartory exercise prescription considerations
- Client’s goals
- Client’s strengths and weaknesses
- Client’s interests
- Client’s lifestyle
FITT
- F: ≥ 5 days/week moderate intensity (or ≥ 3 days/week vigorous intensity)
- I: 3-6 METS (moderate) or > 6 METS (vigorous)
- HRR 40-60%
- T: 20-60 min (> 10 min/session)
- T: rhythmical aerobic activities Type A-D
- V: > 1,000 kcal/week; 500-1,000 METmin/wk
- P: dependent on stage of conditionion
o Limitations of MET Method:
- MET values of activities are only estimates
- MET cost varies with skill (mechanical efficiency)
- Environmental Factors (heat, altitude affect MET cost)
Limitations on the HR methods
- Predicting HRmax can lead to large errors in exercise intensity
- HRmax varies with exercise mode
- HR is affected by various factors (medications, environment)
