FUNdamental stage should be:

A
  • fun
  • quality participation in a wide range of sports
  • development of motor skills
  • development of agility, balance and coordination
  • low voluming training for speed and endurances using FUN games
  • simple rules and ethics of sports
  • strength training using child’s own body weight
35
Q

Learning to Train stage involves:

A
  • further development of fundamental skills
  • learning general overall sports skills
  • continuing strength development
  • basic flexibility exercises
  • develop endurance with games and relays
  • develop speed with specific activities during the warm-up
  • developing knowledge of warming up, cooling down, stretching, hydration, nutrition, recovery, relaxation and focusing
  • structuring of any competition
36
Q

Endurance athletes are advised to have a high

A

carbohydrate diet

37
Q

to reduce risk of injury through being overtired, some athletes increase their carbohydrate intake when engaged in

A

heavy training or high level competition

38
Q

Each time you exercise, glycogen becomes

A

depleted to a certain extent

39
Q

To delay fatigue during exercise, take carbohydrates in drink form to ensure easier and quicker

A

absorption

40
Q

To avoid hypoglycaemia (low blood sugar) during exercise, carbohydrate should not be consumed within

A

one hour of the start of exercise

41
Q

glycogen loading causes a temporary increase in the levels of glycogen in the body just prior to competition by convincing the body to store more

A

glycogen than normal

42
Q

5 Features of an active warm up:

A
  • general cardiovascular warm up (5-10min) - raises body temp to enhance elasticity of muscles, tendons, etc.
  • focusing/concentrating their mind for the training session or performance
  • followed by range of 8-10 dynamic exercises that address all the major muscle groups
  • specific to sport, mimicking the actions involved in the activity
  • Increasing level of intensity
43
Q

8 Benefits of a warm up:

A
  • maintenance of warmth in body and muscles
  • preparation of muscles and joints in a more sport specific manner (static stretching)
  • improvement of coordination and motor ability as well as energising the nervous system
  • mental preparation
  • increased metabolic activity (tissue respiration processes/breaks down fuel at a quicker rate)
  • blood shunting occurs
  • reduces blood viscosity
  • increased breathing rate (better GE due to greater diffusion gradient)
44
Q

3 stages of warm up:

A
  • pulse raiser (5-10 mins CV)
  • sport specific dynamic stretches (8-10)
  • sport specific drills (increase intensity levels throughout)
45
Q

Cool-down is designed to decrease any injurious effects, and prepare for next session. It can do this by:

A

-preventing blood from pooling in the limbs and lactic acid from building up in the muscles

46
Q

cool down helps muscles and tendons to:

A

relax and loosen, stopping them from becoming stiff and tight

47
Q

13 benefits of cool down:

A
  • helps muscles and tendons to relax
  • prevents blood pooling in limbs
  • prevents lactic acid build up in muscles
  • continues metabolic processes
  • keeps blood flowing
  • maintains venous return (skeletal pump)
  • removes CO2 and lactic acid
  • flushes capillaries with oxygenated blood
  • maintains elevated blood pressure
  • purges oxygen debt
  • reduces HR to resting
  • returns body temp. and breathing rate gradually
  • reduces DOMS effects
48
Q

DOMS =

A

delayed onset of muscle soreness

49
Q

DOMS is caused by:

A

damage to muscle fibres and connective tissue (inflammation and increased local muscle and eccentric muscle contractions)

50
Q

6 ways to avoid DOMS:

A
  • undertake an active dynamic warm-up
  • avoid movements that entail strenuous eccentric muscle action at start of training programme
  • gradually increase exercise intensity and duration
  • after initial stages: do extra amounts of eccentric exercise that may cause/have caused DOMS
  • undertake an active cool-down (include passive stretching)
  • consider therapeutic massage
51
Q

to recover from soft tissue injury or general fatigue, 9 ways to recover:

A
  • light aerobic activity
  • stretching
  • therapeutic massage
  • contrast showers
  • sleeping/lying down still
  • ice baths
  • food
  • hydration
  • whirlpool baths
52
Q

What treatment is used for acute soft-tissue injury:

A

RICE

53
Q

R =

A

Rest as soon as injury occurs

54
Q

I =

A

Ice, injured area should be iced for 10-15 minute then taken off for 20 min

55
Q

Ice reduces the

A

internal bleeding (due to vasoconstriction) and the flow of fluids from damaged cells and controls inflammation and swelling

56
Q

C =

A

Compression, reduces or helps control swelling

57
Q

E=

A

Elevation, helps reduce swelling and inflammation

58
Q

Elevation is most effective if the injured area is elevated above the level of the

A

heart

59
Q

Cryotherapy is the use of cooling measures to treat

A

chronic or acute injuries

60
Q

Cryogenic chamber therapy is a treatment for

A

muscle and joint pain

61
Q

It is important to replenish the carbohydrate and the glycogen stores

A

after exercise

62
Q

during the core strength training for the rehabilitation phase, the performer should focus on the whole movement/kinetic chain - a deficiency in one part of the chain can cause a problem or an injury in

A

another part

63
Q

Water training is often used when athletes need to

A

maintain cardiovascular fitness while continuing their sport-specific training patterns, but without exposing the damaged tissues to further trauma

64
Q

To undertake aquatic therapy, the performer adopts a running posture from that basic technique almost any sport-related movement can be

A

developed and replicated

65
Q

Therapeutic massage is the application of massage techniques to the

A

muscle and connective tissues of the body to enhance and maximise sport performance

66
Q

Therapeutic massage is used to increase the

A

range of movement and flexibility and to relieve muscle soreness

67
Q

Therapeutic massage may help injury prevention and promote

A

faster recovery from high-intensity training and injury

68
Q

(PROPRIOCEPTIVE TRAINING) Proprioception is the coordination of balance and joint-positioning sense. For smooth and coordinated movements to be produced, the brain must know accurately the position of the limbs and joints and also the

A

rate of movement of the limbs

69
Q

Proprioception info comes from the proprioceptors in the:

A

joints, tendons and muscles (GTO and muscle spindles)

70
Q

If proprioceptive sense isn’t retrained after injury, it is likely to cause a recurrence of the

A

injury

71
Q

Aim of hyperbaric chambers:

A

-Reduce recovery time for an injury

72
Q

Outline of hyperbaric chambers:

A
  • Uses pressures higher than the local atmospheric pressure
  • The pressure increases the amount of oxygen that can be breathed in, which means more oxygen can be diffused to the injured area
73
Q

Hyperbaric chambers simulate:

A

-air pressure at altitude or depth

74
Q

Benefits of hyperbaric chamber:

A
  • Boosts white blood cell activity in injured areas (controlling infections)
  • Vasoconstriction (reduces blood flow to injured area) - helps to reduce pressure and swelling
  • More oxygen can reach the injured area
  • Enables quicker healing time
  • Reduces lactic acid build up
75
Q

Effects of hyperbaric chambers:

A
  • Hyperoxia
  • Enhanced oxygen delivery
  • Saturates blood plasma and haemoglobin with oxygen
  • RBCs = more malleable (increases their ability to pass through restricted blood vessels)
  • Increased oxygen saturation throughout the body allows body to get oxygen required for ATP resynthesis for energy
76
Q

Oxygen tents, also known as

A

hypoxic tents

77
Q

Oxygen tents simulate:

A

effects at high altitude by providing a low-oxygen environment

78
Q

Oxygen tents - oxygen depletion causes production of higher levels of

A

haemoglobin (more oxygen can be extracted from the blood for extra energy)

79
Q

Oxygen tents used for:

A

endurance athletes

80
Q

Benefits of oxygen tents/hypoxic:

A

-Higher VO2 max - recovery from injury more quickly as more oxygen can reach the injury enabling cells to heal
-Aids quicker tissue regrowth
/
-improves athlete’s ability to work as more O2 is available to working muscles
-increases oxygen carrying capacity of blood
-produces more RBC and haemoglobin

81
Q

Oxygen tents do not speed recovery, but do mean that after recovery, they will have retained a level of fitness that allows them to

A

return to sport almost immediately and achieve some of the positive adaptations of altitude training
