HEALTH RELATED FITNESS COMPONENTS

Summary

The video discusses the two components of physical fitness: skill-related and health-related. Health-related components are emphasized as the foundation for overall fitness, including muscular strength, endurance, flexibility, and body composition. Specific exercises such as push-ups for strength, curl-ups for endurance, and the sit-and-reach test for flexibility are mentioned. Additionally, the importance of maintaining a healthy body composition to reduce the risk of diseases like heart disease and diabetes is highlighted, with instructions on calculating BMI and waist-hip ratio provided. The video concludes with a prompt to watch a follow-up video on calculating BMI and waist-hip ratio.

Takeaways

• 🌅 Good morning everyone, today's discussion is about health-related fitness components.
• 💪 Health-related components should be developed first as they serve as the basic foundation for skill-related components.
• 🏃 The health-related components include cardiorespiratory endurance, strength, flexibility, power, speed, and coordination.
• 🏋️ Muscular strength is the ability of muscles to exert a single maximum force; pushups are a good test for this.
• 💪 Muscular endurance is the ability of muscles to exert force repeatedly or hold a contraction over time; abdominal curl-ups are a common test.
• 🤸 Flexibility is the ability of joints to move through their full range of motion; tests include the sit and reach wall test.
• ⚖️ Body composition refers to the proportion of fat and non-fat mass in the body; BMI and waist-hip ratio are common measures.
• 🧘 Flexion is the bending of a body segment, while extension is the straightening of it.
• 👐 Abduction is moving a limb away from the body, while adduction is moving it towards the body.
• 📏 In your next activity, you will watch a video on how to compute BMI and waist-hip ratio.

Q & A

What are the two main components of physical fitness discussed in PE 103?

The two main components of physical fitness discussed in PE 103 are skill-related components (power, speed, agility, coordination, balance, reaction time) and health-related components.

Why should health-related components be developed before skill-related components?

Health-related components should be developed first because they serve as the basic foundation for performing skill-related components.

What is muscular strength and how is it measured?

Muscular strength is the ability of a muscle to exert or apply a single maximum force during contraction to overcome resistance. It can be measured through exercises like pushups, either the 90° pushup or the modified pushup.

How is muscular endurance defined, and what test can be used to measure it?

Muscular endurance is the capacity of a muscle or muscle group to exert force repeatedly or to hold a contraction over a period of time. It can be measured through tests like abdominal curl-ups or crunches.

What is flexibility, and what are some examples of flexibility movements?

Flexibility is the functional capacity of the joints to move freely through a full range of motion. Examples of flexibility movements include flexion (bending of a body segment), extension (straightening of a body segment), abduction (moving a limb away from the body), and adduction (moving a limb toward the body).

What test can be used to measure flexibility?

Flexibility can be measured through tests like the sit and reach, shoulder flexibility test, and sit and reach wall test.

What is body composition, and why is it important for health?

Body composition refers to the proportion of fat and non-fat elements (bones, muscles, organs) in the body. A lower percentage of body fat and a higher percentage of fat-free mass is healthier, reducing the risk of heart disease, cancer, diabetes, and obesity.

How can body composition be measured?

Body composition can be measured through tests like BMI (Body Mass Index) and the waist-hip ratio.

How do you calculate BMI?

BMI is calculated by dividing weight in kilograms by height in meters squared (BMI = weight (kg) / height² (m²)).

What is the waist-hip ratio, and how is it measured?

The waist-hip ratio is a measure of body fat distribution. It is calculated by measuring the waist and hips in inches and dividing the waist measurement by the hip measurement (waist/hip).
