Study Notes

Physical Activity and Health Overview

Physical activity involves any muscle movement that expends energy, such as running or dancing.
Regular physical activity enhances health and reduces illness risk.

Types of Aerobic Activities

Moderate-Intensity Aerobics: Involves activities like brisk walking.
Vigorous-Intensity Aerobics: Includes running or swimming laps.

Muscle and Bone Strengthening

Muscle Strengthening Activities: Exercises that build muscle size and strength through resistance.
Bone Strengthening Activities: Activities that promote bone density through impact, like running.

Energy Systems in Body

Energy: Necessary for physical activity, metabolic functions, and maintaining temperature.
ATP-CP System: Quick energy source for high-intensity activities lasting about ten seconds.
Phosphagen System: Fastest method to regenerate ATP for muscle energy.
Anaerobic Glycolysis System: Provides energy for medium to high-intensity activities.
Aerobic Energy System: Sustains low-intensity activities for extended periods.

Eating Habits and Health

Balanced nutrition is vital; improper eating can lead to underweight or obesity.
Sleep Requirements: 6 to 8 hours is essential for restorative health.
Poor sleep habits include staying up late, internet addiction, and eating before bed.

Stress Management

Stress is influenced by various factors including work overload and environmental conditions.
Unmanaged stress can lead to health issues such as hypertension and sleep disorders.

Types of Eating

Fuel for Performance: Proper nutrition before training is crucial for athletes, emphasizing the balance of food groups.
Emotional Eating: Consuming food in response to emotional states rather than physical hunger.
Social Eating: Eating for social engagement rather than hunger.
Distracted Eating: Eating while engaging in other activities often leads to overeating.

Cardiovascular Endurance: Ability of the heart and lungs to supply oxygen during sustained activity.
Muscular Strength: Maximum exertable force in a single effort.
Muscular Endurance: Sustaining muscle performance without fatigue.
Flexibility: Range of motion available in joints.
Body Composition: Ratio of fat, bone, water, and muscle in the body.

Barriers to Physical Activity

Personal Barriers: Time, lack of motivation, fear of injury, and lack of support can inhibit physical activity.
Environmental Barriers: Accessibility of facilities, neighborhood safety, and recreational opportunities determine participation levels.

Recommendations for Healthy Living

Engage in various types of physical activities regularly to improve overall health.
Maintain a balanced diet and practice mindful eating to enhance well-being.
Establish good sleep routines and manage stress effectively through appropriate techniques, including physical activity.
