Q

how progressive overload achieved (aerobic, strength ,flexibility)

A
  • aerobic training: increasing intensity, frequency, duration, training
  • strength, increasing sets, reps, decrease rest times
  • flexibility: increase stretch

23
Q

specificity

A

type of exercise used should be specific to task requirements, energy systems, muscle groups and components of fitness involved in task
eg. sprinter needs to train fast twitch muscle fibres whist developing anaerobic threshold and lower leg muscles

24
Q

reversibility

A

training effects gained from training can be quickly lost if person does not participate in training for >2 weeks

25
Q

variety

A

training in variety of methods to decrease boredom, increase training motivation and therefore productivity and success

26
Q

training thresholds

A

point during exercise that when surpassed, physiological changes will occur

27
Q

aerobic training threshold

A
  • intensity at which athletes need to work to produce aerobic training effect
  • around 65-70% MHR
28
Q

anaerobic threshold

A
  • point at which athlete can no longer supply sufficient oxygen (80% MHR)
29
Q

aim of warm up

A

allows players to gradually adapt and prepare themselves both physically and mentally for exercise

30
Q

effects of warm up

A
  • increase blood flow to muscles causing ^body temp.

- muscles, ligaments and tendons more supple and elastic reducing possibility of muscular tear, causing injury

31
Q

psychological benefits of warm up

A
  • increase motivation
  • reduce anxiety
  • allow level of comfort to be adapted to atmosphere in stadium or playing area
32
Q

cool down

A
  • allows for active recovery, gives body time to return blood to heart rather than letting blood pool in muscles, rebuild energy stores
  • should include period of stretching and be active lasting 5-10min
33
Q

psychological adaptions in response to training

A

HOMERS
- heart rate, oxygen uptake and lung capacity, muscle hypertrophy, effec on fast/slow twitch muscle fibres, stroke volume and cardiac output

34
Q

stroke volume

A
  • amount of blood leaving left ventricle each time heart beats
  • increase in training, increases SV therefore allowing more blood to be ejected each time a beat occurs, ultimately leading to increase in CO
35
Q

resting heart rate

A
  • contractions heart makes in min at rest
36
Q

cardiac output

A
  • amount of blood leaving heart each min.
37
Q

oxygen uptake

A

amount of oxygen absorbed into blood stream during exercise and amount of oxygen used per min

38
Q

lung capacity

A

amount of air that can move in and out of lungs during a breath

39
Q

haemoglobin level

A
  • protein found in red blood cells.

- function to absorb oxygen at lungs and carry oxygen to working muscles via blood stream

40
Q

muscle hypertrophy

A

increase in diameter of muscle

41
Q

slow twitch muscle fibres

A
  • most commonly used in aerobic exercises

- enhanced through part. in aerobic activities

42
Q

fast twitch muscle fibres

A
  • used in anaerobic activities and fatigue faster than slow twitch
  • enhanced by undertaking training creating muscular power
43
Q

pre performance dietary need for distance runner

A
  • high carb intake to supply muscle glycogen; primarily through carb loading
  • pre-race meal; high carbs, low fat, GI (slower release og glucose) and protein, eaten 4+ hrs before to avoid gastrointestinal problems
  • consume foods easy to digest (eg. sports drinks) closer to event to provide accessible source of glucose
  • proper hydration
44
Q

During performance dietary need for distance runner

A
  • sports drinks/gels for glucose top up + hydration
45
Q

+ve of vitamin supplementation

A
  • cheap, plentiful, regulated
  • not toxic if excess is consumed
  • helps correct vitamin deficiencies
46
Q

-ve of vitamin supplementation

A
  • contributes to muscle, joint pains and headaches

- excess supplementation does not improve performance

47
Q

vitamins

A

organic compounds required in small qtys for normal growth, development and metabolism

48
Q

minerals

A

inorganic substances incl. calcium, potassium, iron

- important to cellular functions eg. muscle contractions, fluid balance and maintenance of energy systems

49
Q

+ve of mineral supplementation

A
  • iron supplements can aid in formation of haemoglobin
  • calcium supplements can lead to strong bones
  • assists in immune system functioning
50
Q

physiological effects of caffeine

A
  • increased HR and can affect heart rhythm
  • relaxes smooth muscle
  • produce symptoms of anxiety in high doses
  • decreases rating of perceived exertion
    helps cognitive processes such as concentration, alertness, memory
51
Q

+ve of caffeine supple

A
  • helps cognitive processes eg. concentration
  • moilises fat stores and converts them into free fatty acids (spare glycogen)
  • delays perceptions of fatigue
52
Q

-ve of caffeine suppl.

A
  • produces anxiety in high doses
  • direutic effect - increasing risk of dehydration
  • over arousal
53
Q

recovery strategies

A
  • physiological eg. cool down and hydration
  • neural eg. hydrotheraphy, massage
  • tissue damage strategies eg. cryotherapy
  • psychological strategies eg relaxation
54
Q

hydrotherapy NEURAL

A
  • use of water to assist recovery of muscles (eg. hot water immersion and contrast water therapy)
  • cyclist immersing body in warm water after training session increases blood flow to remove lactate, increased skin + cored temp, decrease of muscle stiffness
55
Q

benefits of massage to performance NEURAL

A

increased blood flow, decreased muscle tension and soreness, increased joint flexibility, decreased nervous system tension

56
Q

cryotherapy TISSUE DAMAGE

A
  • form of cryotherapy is CWI involves immersing body in water ~10-15 degrees for ~5m
  • results in decreased (core/muscle/skin) temp, reduced soreness, reduces inflammation, alleviates spasm and muscle pain, changes in cardiac response and blood flow
