Factors that affect performance

Factors that affect performance- Disabililty

  • Physical
  • Mental
  • Temporary
  • Permanant

Sports and equipment are adapted to people with disabilites e.g the Paralympics

Factors that affect performance

Factors that affect performance- Age

As you get older:

  • Flexibilty reduces
  • Strength decreases
  • Oxygen capacity reduces (atreries loose elasticity)
  • Longer recovery time
  • Skill levels improve

Age divisions in competitive sports an example of this is school football teams that are spilt into age groups, also international events such as wimbeldon.

Factors that affect performance- Enviroment

The enviroment can affect participation and performance:

  • Weather
  • Pollution
  • Altitude
  • Humidity
  • Terrain

Factors that affect performance

Factors that affect performace - Risk and Challenge

In every activity there is an element of risk and challenge

Risk: The possibilty of suffering harm, loss or danger

Challenge: A test of your ability or resources in demanding situation

Factors that affect performance

Factors that affect performance- Gender

Body shape, size and pyhsique are different in men and women:

  • Women have a flatter and broader pelvis, smaller heart and lungs, and a higher percentage of fat
  • Women are more flexible due to the fact that have less muscle mass
  • Rates of maturity differ so after the age of 11 teams become single sex

Some sports are shows to suit certain genders (sexual discrimination), e.g football is asscocited with men and netball wiht women

Factors that affect performance

Factors that affect performance- Activity levels and needs

Competitive:           An activity that involves some form of contest

Recretational:         Any form of play, amusment, perfrmed as a hobby

Individual factors:   Age, Jobs, lesuire time, money

Performance level: Amount of times and level of performance

Factors that affect performance

Factors that affect performance- Somatotyping

Endomorph- Pear shapes, wide hipe, wide shoulder, tendency to gain weight, suited to rugby

Ectomorph- Slender, thin, narrow shoulders and hips, little muscle and body fat, e.g marathon runners, jockeys or gymnasts

Mesomorph- Wedge shaped, broad, wide shoulders, minimum amount of fat, narrow hips muscled arms and legs, suited to swimming and speed events

7 of 35

Factors that affect performance

Factors that effect performance- Fatigue and stress

Both can fatigue aand stress can have an impact on performance

Fatigue:

  • Extreme pyhsical or mental tiredness caused by exersion
  • Concentration levels will decrease
  • Local muscular fatigue is when a  group of muscles is unable to carry on contracting and movement stops

Stress:

The body's reaction to a pyhsical, mental or emotional adjustment. Excitement, anxiety or nervousness can cause stress and effect performance

8 of 35

Injury

Injury

Internally caused injuries are when the palyer is responsible:

  • Overuse injuries (stress fractors, tennis elbow)
  • Sudden injury (sprain, strain, twisting etc)

External injuries are caused by equipment, oppenent or conditions:

  • Foul play or incorrect action (rules prevent these)
  • Impact injuries (contact or equipment)

Equipment and clothing:

  • Blisters/tightly fitting/faulty/damaged

Precaution:

  • Risk assesment/ warm ups/ rules

Types of training

Types of training

Circuit training:

  • Fitness circuit - to increase fitness, strength and cardiovascular endurance (excersises such as pressups, situps, shuttle runs etc)
  • Skills circuit- excersises aimed at developing certain skills
  • Running the circuit- you can either do timed circuits, fixed load or varied laps

Weight training:

  • Improves muscular, strength, size, bulk, tone. Done in reps and sets using free standing or specialised weights

Apects of training

Aspects of training

  • Warm up
  • Fitness or excerisse phase
  • Skills or teamplay phase
  • Warm down

Training threshold - the minimum heart rate to be achieved to ensure fitness improves

11 of 35

Training methods

Training Methods

  • Continuous training (keep heart rate high)
  • Interval training (periods of work, periods of rest)
  • Fartlek training (form of interval training)
  • Multistage fitness test (or bleep test)
  • Alltitude training (improves performance at sea level)
12 of 35

Training - Levels of participation

Training- Levels of participation

Pre-season - The time of leading up to the majority of competition, concentrating on fitness and developing techniques

Peak season- This is the main competitive period concentration on skills and ongoing fitness

Post season- The main period of rest and recovery but level of general fitness needs to be kept up

Avaliable time and funds can also affect levels of particpation

The skeleton

The Skeleton

Joints:

  • Hinge ( e.g elbow)
  • Ball and socket (e.g hip)
  • Pivot (e.g wrist)
  • Saddle (e.g thumb)
  • Gliding (e.g the hand bones)
  • Condyloid (e.d wrist)

Tendons: very strong, non-elastic cords joining the muscle to the bone

Cartilage: Tough and flexible tissue act as a buffer between bones and joints

Liagments: Link the joints

18 of 35

The skeleton

The skeleton

Function:

  • Movements at joints
  • Support for muscles and vital organs
  • Shape of body
  • Protection
  • Blood-cell production in the bone marrow

Bones:

  • Long bones (e.g femur)
  • Short bones (e.g phalanges)
  • Flat or plate bones (e.g skull)
  • Irregular bones (e.g vertebrae)
19 of 35

Role of skeletal system

Role of skeletal system

Joints:

  • Freely moveable (e.g synovial joints)
  • Slightly moveable (e.g vertebrae in the spine)
  • Immovable (e.g skull)

Movements:

  • Flexion - e.g bending the elbow
  • Extension - when the angle at the joint is increased
  • Abduction- movement of bone away from midline of body
  • Abbduction- Where the bone moves inwards towards the body
  • Rotation- Where the bone or limb moves freely in a cave
20 of 35

Muscle Movements

Muscle movements

  • Flexors- muscles that bend a limb at a joint by contracting
  • Extensors- work with and against flexors and straighten a limb a joint by contracting
  • Adductors- move a limb towards the body
  • Abductors- move a limb away from the body

Isotonic contractions- can be concentric (when muscle shortens) or eccentric (when muscle lengthens to original state)

Isometric contractions- Muscles working to keep, joint stable

21 of 35

Muscle movements

Muscle movements

Origin- the end of the muscle attached to the fixed bone

Insertion- the end of the muscle attached to the bone that moves

Prime mover- the muscle that initally contracts to start a movement (also know agonist)

Antagonist- the muscle that relaxes to allow a movement to take place

22 of 35

Muscular system

Muscular system

Three types of muscle:

1. skeletal- Know voluntary muscles make up majority of muscles in the body. these muscles are under our consoious control

2. Cardiac muscles- Invountary muscles they work automatically and constantly

3. Involuntary- muscles you cannot control found in the walls of intestines and blood vessels. They contract to allow crucial body funtions

The respiratory system

The respiratory system

Aerobic respiration: respiration that occurs in the presence of oxygen. For example marathon running

Glucose + oxygen = (energy) + carbon dioxide + water

Anaerobic respiration: respiration that occurs in the absence of oxygen and an example is 100m sprint. No oxygen in muscles

Glucose = (energy) + lactic acid

24 of 35

Cardiovascular system

Cardiovascular system

  • Blood pressure- the force of the circulating blood on the walls of the artiries
  • Max heart rate = 220 minus age
  • Training zone- the range of the heart rate within a specific training effect will take place
  • Cardio. endurance- The ability of the heart and lungs to keep supplying oxygen in the blood stream to the body
  • Improving cardio endurance- take part in excersise that raises your pulse
25 of 35

Health

Health

Definition of health:

A state of complete pyhsical, mental and social wellbeing and not merely the absence of disease or infirmity

 

  • Performance enhancing drugs are unlawful drugs that help improve performance
  • Smoking can cause bronchitis, lung cancer, heart disease etc
26 of 35

Healthy lifestyle

Healthy lifestyle

Sedentary- Physically inactive for long periods of time

 

Changes to body when excersising:

  • Heart rate increases
  • Body temperature increases
  • Muscles become tired or heavy
  • Increased breathing

Lesuire and Recreation

Lesuire and recreation

Lesuire time:

The time you have spare when you can choose what to do (time not eating/sleeping/hygiene/ and at work). there are two types of lesuire; active and passive 

Recreation:

  • Intrisic reward- and activity that gives a person individual satisfaction
