Study Notes

Aerobic vs. Anaerobic Exercise

Aerobic Exercise: Requires large amounts of oxygen, performed over prolonged periods (20-60 minutes) to develop muscular endurance. Examples include jogging and dancing.
Anaerobic Exercise: Done with low oxygen supply, characterized by shorter durations and explosive movements like sprints and lifting.

Elements of a Training Program

Warm-Up: Increases body temperature, enhances flexibility, and prepares muscles for physical activity.
Workout/Activity Proper: Focuses on skill improvement, considering factors such as intensity.
Cool Down: Aids in the recovery process by returning the body to its normal state through slow movements.

Intensity of Physical Activity

Light Physical Activity: Requires minimal effort, suitable for encouraging overall activity. Indicators include being able to sing during the activity.
Moderate Physical Activity: Burns 3 to 6 METs of energy, includes activities like brisk walking and cycling. Indicators include quickened breathing and light sweating after 10 minutes.
Vigorous Physical Activity: Requires more than 6 METs, includes running and jumping rope, characterized by rapid breathing and difficulty speaking.

MET (Metabolic Equivalent of Task)

Represents exercise intensity based on oxygen consumption.
One MET equals consumption of approximately 3.5 ml of oxygen per kg of body weight per minute.

Comparison of Activity Intensity

Light Intensity: Activities like slow walking, standing light work, and light playing.
Moderate Intensity: Brisk walking, gardening, and active household chores.
Vigorous Intensity: Activities such as jogging, shoveling, and fast cycling.

Training Considerations

Maximize Potential: Focus on workloads that lead to effective training results.
Adaptation and Recovery: The body adjusts post-training, and recovery is essential to prevent overuse injuries.
Individual Differences: Training should consider the athlete's age, gender, injury status, and fitness level.
Reversibility: Lack of training can lead to decreased fitness levels.

Barriers to Physical Activity

Health Limitations: Conditions such as hearing loss and poor eyesight can hinder participation.
Psychological Barriers: Fear of injury, lack of motivation, and negative past experiences can deter individuals.
Environmental Factors: Accessibility of facilities and social support plays a crucial role in physical activity levels.

Nutrition for Health

Importance: Proper nutrition is vital for growth, development, and disease prevention.
Key Nutrients: Six types - water, protein, carbohydrates, fats, vitamins, and minerals. Macronutrients are needed in large amounts, while micronutrients are needed in smaller quantities.
Benefits of Good Nutrition: Maintains health beyond weight management, enhancing overall well-being.

Improving Eating Habits

Strategies: Reflect on eating habits, replace unhealthy choices with healthier ones, and reinforce positive changes.
Healthy Eating Tips: Incorporate more fruits and vegetables, control portion sizes, and reduce intake of fat, salt, and sugar.

F.I.T.T Principle

As a method for planning training sessions, stands for Frequency, Intensity, Time, and Type of exercise. Adaptations should be made based on individual needs and goals.
