Revision Guide: Move Like a Machine

The musculoskeletal system consists of bones, muscles, and joints that enable movement.

Bones provide structure, protect organs, and store minerals essential for health.

Muscles contract to create movement; they work in pairs - one contracts while the other relaxes.

Types include hinge (e.g., knee), ball-and-socket (e.g., shoulder), allowing various movements.

Flexion decreases the angle between body parts; for example, bending your elbow during bicep curls.

Extension increases the angle; straightening the arm after a bicep curl is an example.

Squat jumps enhance leg strength, involving bending at the knees and jumping upward.

Push-ups strengthen the upper body; maintain a straight line from head to heels.

Resistance bands are useful for strength training; they provide variable resistance during workouts.

Balancing exercises improve coordination and stability, essential for sports and daily activities.

A proper warm-up prepares the body for exercise, enhancing performance and preventing injuries.

Team exercises foster collaboration; they develop trust and communication skills among participants.

Correct form and technique during exercises prevent strains and injuries. Always listen to your body.

Stretching increases flexibility and prepares muscles for vigorous activity, reducing injury risks.

Primary muscles used include quadriceps, hamstrings, and glutes, essential for explosive movements.

Proper jumping uses both strength and timing; a good arm swing aids upward thrust.

The body uses ATP-CP and anaerobic systems for quick bursts of energy during activities like squats.

Dynamic stretching, like arm circles, helps warm up muscles, enhancing range of motion before workouts.

Cooling down after exercise helps lower heart rate and aids in muscle recovery and flexibility.

Circle time allows for clarification of concepts and group discussions about fitness and health.
