Unit Breakdown UNIT 8: 1. Explain what constitutes a healthy, active lifestyle Exercise and physical activity immediate and short-term effects of participation in exercise and physical activity (isometric and isotonic contractions, responses – increased fuel/energy demands, lactic acid) effects of regular participation in – and long-term effects of participation in – exercise and physical activity (adaptations – increased strength and size/hypertrophy) the potential for injuries such as muscle strain and muscle atrophy (due to injury and inactivity), and their treatment using common techniques Rest (rest required for adaptation to take place, time for recovery before next exercise session) Diet (effects of protein in building and repairing muscles) Performance enhancing drugs (use of steroids to aid muscle 3 of 28 building and recovery).

Movement of muscles Flexion- bending Extension- straightening Abduction- take away from body Adduction- bring towards body Rotation- move in circular motion

DETOIDS • Is the muscle that gives the rounded shape to the shoulder. It is a powerful muscle that abducts (abduction) the arm (raises your arm sideways). • Example: bowling in cricket

BICEPS • Found at the front of the upper arm. • Bends or flexes (flexion) the forearm at the elbow • Example: drawing a bow in archery

TRICEPS • Found behind the upper arm • Extends (extension) the forearm at the elbow • Extends (extension) the arm at the shoulder • Example: a smash in badminton

PECTORALS • Cover the chest • Powerful muscle that adducts (adduction) the arm at the shoulder across the chest and draws the arm forwards to rotate (rotation) • Used for keep breathing • Example: swimming using the front crawl

ABDOMINALS (4 muscles) • These hold your stomach in! • Allow you to flex (flexion) or bend forward • Rotate the trunk • Strengthen the abdominal wall • Help with breathing • Example: performing a pike position on trampoline, diving etc.

TRAPEZIUS • Holds back the shoulders and helps to control the shoulder girdle • It holds and rotates (rotation) your shoulders. Moves your head back and sideways • Example: a player holding his head up in a rugby scrum

LATISSIMUS DORSI • It adducts (adduction) the arms, and rotates (rotation) to draw them back and inwards towards the body • Extends (extension) the arm at the shoulder • Example: swimming the butterfly stroke

GLUTEALS • Found in the ‘bum’ • Pulls the leg back at the hip (extension). Raises sideways at the hip (abduction) • Example: Sprinting and stepping up during rock climbing

HAMSTRINGS (3 muscles) • Found in the back of the upper leg and stretch from the bottom part of the pelvis to the tibia • They flex/bend (flexion) the knee. Example: drawing the leg back before kicking a ball

QUADRICEPS (4 muscles) • Found on the front of the upper leg • extends (extension) the knee joint straightening it • Examples: taking off in high jump and kicking a ball

GASTROCNEMIUS • Found at the back of the lower leg • Attached at the ‘Achilles’ tendon • straightens (EXTENSION) the ankle joint so that you can stand on your tiptoes • Example: running

Sporting action Taking off the board in long jump Main muscles used Movements produced by these muscles Quadriceps and Flexion and Extension at the hamstrings and knee. Pulling leg back at the gluteals hips Kicking a football Quadriceps and hamstrings Flexion and Extension at the knee Abdominals Flexing the trunk of the body Bicep, triceps and pectorals Flex arm for preparation. Extends arm on contact. Adduct arm back to side of trunk. Adduction of the arm at the shoulder Rowing Tennis Serve Swimming the front crawl Pectorals

Plenary: What have we learned today? Who can stand up and talk to me, giving me the most description, explanation and application for the next few slides

Relating to a sporting action Bicep (agonist) contracts when the rower brings the oar towards him. While the Tricep (antagonist) relaxes.

Biceps flex at the elbow Quadricep extends at the knee Hamstrings flex at the knee Gastrocnemius extends at the ankle

Quadricep extends at the knee Gastrocnemius extends at the ankle Hamstring (antagonist) Relaxes as the Quadricep contracts

Relating to a sporting action Quadricep extends at the knee Hamstring (antagonist) Relaxes as the Quadricep contracts
