Factors Affecting Participation and Performance

MUSCLES

Name: ………………………………… G.C.S.E. P.E. Teacher: …………………………………….


By the end of this booklet you should: Be able to describe and explain how muscles and their

composition, function and action affect movement and performance (fast twitch for power and strength activities, slow twitch for endurance activities).

Know the location of the major muscle groups (deltoid,

trapezius, pectorals, biceps, tripceps, latissimus dorsi, abdominals, gluteals, guadriceps, hamstrings and gastrocnemius) and how activities and exercise affects these muscles.

Be able to explain the role of antagonistic pairs, prime movers

and synergist during a range of different physical activities. Be able to describe the role and function of tendons during

movement. Be able to explain how performance and participation can

improve as the efficiency of the muscle improves.


MUSCLES

Every movement that takes place in your body depends on muscles. They work by shortening or contracting. There are three kinds of muscle: 1. Involuntary (smooth)

THE MAJOR MUSCLE GROUPS Complete the worksheet by choosing from the list below, and writing in the boxes provided, the correct name and functions for the muscles and tendons illustrated.

Muscles: - Gluteus Maximus – Tripceps – Gastrocnemius – Quadriceps – Deltoids – Hamstrings – Pectoralis Major – Biceps – Achilles – Rectus Abdominals.

Action: Raises the arm away from the side (Abduction) Straightens (extends) the arm at the elbow Bends (flexes) the arm at the elbow joint Flexes the trunk forward Raises the body onto the toes Straightens (extends) the leg at the knee Bends (flexes) the leg at the knee Straightens (extends) thigh at the hip joint Pulls outstretched arms together in front of body Transmits the power of the calf muscle to the

foot


Complete the worksheet by writing in the names of the muscles shown and give one example of how that muscle is used in sport. For example the triceps muscle is used in putting the shot.


HOW MUSCLES WORK

Voluntary muscles produce movement by contracting and relaxing. Muscles get shorter when they contract and longer when they

relax again. All voluntary muscles are attached by tendons to bones. These

points of attachment are called origins and insertions. Some muscles have more than one attachment at one end (this is an indication of strength of the muscle) e.g. the …………………………………. and the …………………………………….

Using page 12 of GCSE PE for OCR, label the diagram below. Muscles always work in …………………………… because they can only …………………………… and not …………………………… These pairs are known as …………………………… muscles. For movement to occur at a joint, one muscle shortens (……………………………), whilst the other muscle lengthens (……………………………). The muscle that contracts is known as the …………………………… or …………………………… muscle. The muscle that relaxes is known as the…………………………… muscle. Muscles which hold the bone in place, and also contract to help the prime mover are known as …………………………….

Press Ups Elbow


TENDONS

Tendons attach ………………………………… to …………………………………

Ligaments attach ………………………………… to ………………………………… As a muscle contracts, the tendons at each end of the muscle takes the strain. Tendons must therefore be strong enough to work under heavy loads and resist the intense, sudden muscular contractions involved in sport, e.g. throwing the javelin or cricket ball. The tendon of origin resists the pull of the muscle whilst the tendon of insertion exerts the pull on the bone to which it is attached. This causes the joint to bend or straighten. Tendons are a connective tissue which has a less efficient blood supply than skeletal muscle. A thorough warm up will stimulate blood flow to the tendons and this will reduce the chance of injury to the issue. One tendon which is prone to injury is the Achilles tendon.


MUSCLES FOR ENDURANCE AND POWER

Fast and Slow Twitch Muscle Fibres There are two types of muscle fibre present in voluntary muscles. Fast Twitch Fibres Slow Twitch Fibres

FAST TWITCH FIBRES SLOW TWITCH FIBRES

Fast, powerful contractions Contract more slowly and with less power than fast twitch

fibres Burn up their supply of 02 usually

within 10 seconds. They then have to use the body’s store of carbohydrates as a short term

energy source. (Anaerobic Exercise)

Are able to replace their 02 supply while they are working.

(Aerobic Exercise)

Tire quickly Can function for longer periods of time

Used for short term power and strength activities. (Anaerobic

Activities)

Used for longer term endurance activities. (Aerobic Activities)

E.g. Bb Bb

E.g. Bb Bb

The mixture ………….. The fibre distribution varies from person to person. Is inherited. You cannot change the distribution of muscle

fibres, but you can train both types of fibre to make them more efficient.


In many sporting events we often use both types of fibres at different times during the activity. Complete the table below showing examples of the use of both types of muscle fibres in different sporting activities.

ACTIVITY SLOW TWITCH FAST TWITCH

Marathon Running Most of the race Spring finish


THE EFFECT OF EXERCISE AND TRAINING ON MUSCLES

Skeletal muscle responds to training in two ways. Voluntary muscles become stronger and more flexible when they are exercised. This development of the muscle is known as hypertrophy. When exercise stops, due to injury or some other reason, muscles begin to lose the strength and mass that was gradually building up during regular activity. This is known as atrophy (wasting of the muscle). Different activities rely on different muscles and muscular requirement. With regular training muscles adapt well to the exercise that they are required to perform. In activities which involve heavy workloads, e.g. sprinting, new muscle fibres are generated (muscle bulk) until the muscles are strong enough to perform the task. In endurance activities where bulk is of no advantage, muscles adapt to training by utilizing energy more efficiently to delay the onset of fatigue.

SPRINTER MARATHON RUNNER Big, powerful muscles As little bulk as possible Muscles are able to maximise

stored energy in short bursts of all-out activity.

Muscles utilise energy much more efficiently and for much longer periods of time.
