Study Notes

Physical Activities and Getting Fit

Physical activity involves any movement made by body muscles requiring energy expenditure, including running, swimming, and dancing.
Regular engagement in physical activities fosters a healthy lifestyle, improves health, and reduces illness risks.
Aerobic activities, or cardio exercises, enhance heart and breathing rates and induce sweating.
Two types of aerobic activities:
- Moderate-Intensity Aerobics
- Vigorous-Intensity Aerobics
Muscle-strengthening activities promote muscle growth and strength through resistance against weight, a process known as muscle hypertrophy.
Bone-strengthening activities, including weight-bearing activities, stimulate bone growth and strength through physical stress.

Energy System Overview

Energy is essential for physical movement, maintaining body temperature, and metabolic processes.
Energy production is primarily supported by Adenosine Triphosphate (ATP) and Creatine Phosphate (CP).
ATP is a molecule formed from carbohydrates and proteins, serving as a critical energy source.
The phosphagen system rapidly resynthesizes ATP and provides quick energy bursts lasting up to ten seconds.
The Anaerobic Glycolysis System supplies energy for medium to high-intensity activities and is the second fastest energy source.
The Aerobic Energy System supports low-intensity activities lasting from two minutes to several hours.

Health Awareness: Eating Habits, Stress, and Sleep Management

Healthy eating habits are crucial; consuming the right amount and type of food prevents malnutrition, overweight, and obesity.
Recommended sleep duration is 6 to 8 hours to ensure body regeneration and energy restoration.
Poor sleeping habits include staying up late, internet addiction, and eating before bedtime, which disrupt restful sleep.
Stress arises from various factors such as environmental pressures, fatigue, and loneliness and can lead to serious health issues when unmanaged.
Underweight individuals may suffer from malnutrition due to insufficient caloric intake and nutrient deficiency.

Eating for Health

Eating provides energy, strength, and cognitive power; cultural practices often emphasize food during celebrations.
Four types of eating habits affect health:
- Fuel for Performance: Balanced meals providing essential nutrients for athletes before training.
- Emotional Eating: Consuming food in response to emotional states rather than hunger.
- Social Eating: Eating to fit in during social situations, even when not hungry.
- Distracted Eating: Consuming food while engaged in other activities, leading to overeating.

Managing Stress through Physical Activity

Stress is unavoidable and can cause mental, emotional, and physical distress if not managed effectively.
Symptoms of stress include lack of focus, physical weakness, headaches, and emotional instability.
Regular physical activity can serve as a coping mechanism for stress.
Types of physical activities include:
- Aerobic Activities: Promote cardiovascular health through moderate-intensity exercises.
- Anaerobic Activities: Short-duration, high-intensity strength training.
- Lifestyle Activities: Daily routine movements like walking or climbing stairs.
- Play: Energetic activities focused on enjoyment, e.g., playing tag.
- Sports: Governed physical activities, either individual or team-based.

Self-Testing Activity for Health

Physical fitness testing assesses health status and identifies strengths and weaknesses.
Common barriers to exercise include:
- Insufficient time, convenience difficulties, lack of motivation, and fear of injury.
Environmental barriers significantly influence participation in physical activities due to factors like availability of recreational facilities and walking paths.
