Study Notes

Foods as Fuels for Energy

Carbohydrates: Major energy source, derived from starch and sugars; include glucose, the primary sugar in the blood.
Glycogen: Stored form of glucose, composed of interconnected glucose molecules.
Fats: Provide heat and energy; assist in vitamin absorption; sources include meats, dairy products, and vegetable oils.
Proteins: Essential for tissue building and repair; found in meats, fish, eggs, milk, and legumes.

Energy Systems

ATP (Adenosine Triphosphate): Primary energy carrier for bodily functions including tissue repair, hormone production, digestion, and nerve transmission.
Glycolytic System: Breaks down glucose for quick energy with limited capacity.
Oxidative System: Uses oxygen for efficient ATP production, ideal for sustained, longer-duration activities.

Nutrition Strategies for Optimal Performance

Balanced Meals: Focus on complex carbohydrates, lean proteins, and healthy fats.
Hydration: Importance of water intake before, during, and after exercise.
Meal Timing: Eat well 2-3 hours prior to exercise; have a snack within 30 minutes post-exercise.
Supplements: Consider protein shakes or recovery aids for muscle growth and recovery.

Types of Exercise

Aerobic Exercise (Cardio): Utilizes oxygen; promotes endurance and burns fuel for muscle movement.
Anaerobic Exercise: Short, high-intensity workouts; body’s oxygen supply is insufficient; "without air".

Benefits of Aerobic Exercise

Reduces heart disease risk.
Lowers blood pressure.
Enhances lung function.
Aids in weight management.

Benefits of Anaerobic Exercise

Builds muscle strength.
Increases oxygen intake capacity.
Boosts endurance and fatigue resistance.

Exercise Duration and Recovery

Aerobic: Long duration, lower intensity.
Anaerobic: Short duration, high intensity, requires extended rest.

Managing Stress Through Dance

Provides an escape from worries and a method for creative expression.
Encourages mindfulness with both physical and mental benefits.
Creates a supportive dance environment through music, positive attitudes, and self-acceptance.

Physical Fitness Test: Measures health-related and skill-related fitness levels.
Health-related Fitness: Enhances overall well-being; supports daily activity and lowers chronic disease risk.
Foundation for Health: Health-related fitness fosters active lifestyles and long-term health, focusing more on capability than appearance.

Cardiovascular Endurance: Efficient oxygen delivery to muscles; increases energy levels and reduces fatigue.
Muscular Strength: Maximum force generated by muscles.
Muscular Endurance: Sustaining repeated muscle contractions over time.
Flexibility: Ability to move joints with ease; prevents injuries.
Body Composition: Ratio of fat to lean mass; includes BMI categories such as normal, underweight, overweight, and obese.

Balanced Diet: Emphasize fruits, vegetables, lean proteins, and whole grains.
Flexibility Exercises: Incorporate routines like yoga or dynamic stretches.
Strength Training: Utilize weights or bodyweight exercises for muscle development.
Cardiovascular Activities: Engage in running, swimming, or cycling to enhance cardiovascular health.

Agility: Quick reactions and body control during rapid movement changes.
Balance: Maintaining equilibrium; includes static and dynamic balance.
Coordination: Working different body parts together effectively; encompasses both intermuscular and intramuscular coordination.
Power: High force generation in a short time; involves explosiveness and strength.
Speed and Reaction Time: Ability to move quickly and respond swiftly to stimuli; includes strength of muscle response and information processing.
