HS-133 Chapter 9: Improving Physical Fitness

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.
