Study Notes
Importance of Physical Activity
- Inactivity linked to obesity, type 2 diabetes, and chronic health issues
- 25.4% of American adults do not partake in leisure-time physical activity
- 54% of college women and 48% of college men fail to meet activity guidelines
Health Benefits of Physical Activity
- Provides primary and secondary prevention for various health issues
- Decreases risk of cardiovascular diseases, metabolic syndrome, type 2 diabetes, and certain cancers
- Enhances bone mass, improves immunity, mental health, and extends lifespan
Specific Health Benefits of Regular Exercise
- Brain: Reduces stress and depression, improves mood and concentration
- Lungs: Increases respiratory capacity and oxygen extraction
- Heart: Strengthens the heart, decreases heart disease risk, and boosts circulation
- Muscles and Joints: Improves strength, endurance, flexibility, and reduces arthritis-related pain
- Bones: Enhances density, strengthening bones and decreasing osteoporosis risk
Physical Activity Guidelines
- Adults: 150 minutes of moderate or 75 minutes of vigorous activity weekly
- Older Adults: Engage in as much activity as condition allows
- Children: Daily 60 minutes of moderate to vigorous activity
Definitions in Physical Fitness
- Physical Activity: Any muscle movement that enhances health (e.g., walking, swimming, yoga)
- Exercise: Planned, structured movement aimed at improving physical fitness
- Physical Fitness: Balance of health or skill-related attributes for overall fitness
Components of Physical Fitness
- Cardiorespiratory Fitness: Ability of the heart and lungs to supply oxygen efficiently
- Muscular Strength: Force capabilities of muscles in one contraction
- Muscular Endurance: Repeatability of force exertion without fatigue
- Flexibility: Range of motion at joints
- Body Composition: Distribution of fat and fat-free mass in the body
SMART Goals for Fitness Programs
- Specific: Define targeted activities (e.g., resistance training)
- Measurable: Set measurable fitness improvements
- Action-oriented: Plan how to achieve goals with guidance
- Realistic: Set attainable weight or performance increases
- Time-oriented: Define a timeframe for evaluations
The FITT Principle
- Frequency: How often to exercise per week
- Intensity: Required effort level to achieve desired outcomes
- Time: Duration and repetitions needed in workouts
- Type: Specific exercise categories to include
Cardiorespiratory Fitness Guidelines
- Exercise 3-5 days a week at 64-95% max heart rate, lasting at least 20-30 minutes per session
Techniques and Methods of Exercise
- Several exercise options like calisthenics, free weights, and machines for muscle resistance development
- Static stretching recommended for flexibility improvement
Injury Prevention and Treatment
- RICE Method: Rest, Ice, Compression, Elevation for treating fitness-related injuries
- Awareness of proper footwear and environment can prevent injuries like heat-related conditions or hypothermia
Nutrition and Hydration
- Adequate carbohydrate intake before workouts and proper hydration is essential for exercise effectiveness
- Recommendations include specific fluid intake before and during exercise to prevent dehydration.
Special Considerations
- Traumatic injuries result from sudden accidents, while overuse injuries accumulate from repetitive stress.
- Conditions like heat cramps, heat exhaustion, and heatstroke warrant careful monitoring and prevention strategies.
