Physical Fitness and Exercise Principles

Muscular Strength vs. Resting Muscle Activity

• Muscular strength refers to the maximum amount of force a muscle can produce in a single contraction.
• Resting muscle activity, also known as muscle tone, is the low-level contraction of muscles when they are not actively moving.

Importance of Warm-up Exercises

• Warm-up exercises prepare the body for strenuous activity by increasing heart rate, blood flow, and temperature.
• They help prevent injuries by increasing flexibility and reducing muscle stiffness.
• Warm-up exercises also improve performance by increasing power, speed, and endurance.

Benefits of Different Exercises

• Walking is a low-impact exercise that improves cardiovascular health and strengthens muscles.
• Running is a high-impact exercise that improves cardiovascular health and increases caloric burn.
• Using a treadmill allows for controlled and consistent exercise, making it easier to track progress and set goals.
• Swimming is a low-impact exercise that improves cardiovascular health, strengthens muscles, and increases flexibility, with the added benefit of minimal joint stress.

Badminton Faults

• A fault in badminton occurs when the shuttlecock is hit into the net, beyond the boundaries of the court, or does not clear the net.
• A fault also occurs when the shuttlecock is hit twice in a row by the same player, or when the player hits the shuttlecock with their body or clothing.
