Q

How and what happens when LIP is increased

A
  • Able to produce ATP aerobically at higher intensity

- Occurs from chronic adaptations such as increased mitochondria size and number, increased oxidative enzymes

Q

EPO

A
  • Naturally occurring hormone
  • Is a synthetically injected substance that increases RBCs and hence the oxygen carrying capacity of blood as well as Hameoglobin levels

Q

Explain how dehydration affects an athletes ability to recover after intense exercise

A
  • Low blood plasma due to dehydration
    Therefore blood flow to working muscles decreases
    Therefore fewer waste products removed, and less oxygen will be delivered to muscles, meaning body has decreased ability to breakdown lactic acid

Q

Three mechanisms responsible for venous return

A

Muscle Pump- causes veins to be constricted
Respiratory Pump - pressure in thorax and abdomen
Vasocontriction

17
Q

Anaerobic glycolysis system has a ___________ capacity

A

FInite Capacity

18
Q

Physiological or Psychologicla Factors that are affected by SLeep

A
  • ^ Stress or anxiety
  • Decreased effective cognition
  • Decreased performance
  • Decreased Reaction Time
  • Lack of motivation
  • Increased recovery time
19
Q

Important to be hydrated before a marathon becuase

A
  • Able to combat sweat loss

- Able to maintain bodily fluid and is therefore at less risk of dehydration

20
Q

Difference between absolute and relative VO2 Mx

A

Absolute does not take into account athletes body weight, Relative does
Eg- 100kg will have less relative VO2 max than someone weighing 70kg

21
Q

Explain how anaerobic training and its chronic adaptations leads to faster times

A

Leads to increase in capacity to generate high levels of blood lactate and increased tolerance to lactic acid. This generates more power and leads to less reliance on aerobic system

22
Q

Eccentric Contraction =

A

Lengthening

23
Q

Concentric Contraction =

A

Shortens

24
Q

Venous Return

A

Is the rate of blood flow back to the heart

25
Q

Main Reasons for WADAs establishment

A
  • Coordinate and Moniter
  • To promote
  • TO fight against doping in sport
26
Q

Training anaerobically leads to

A

Lactate tolerance

27
Q

Hyperbaric Chambers

A

Saturatio of oxygen through the body

28
Q

Predominant energy system when working at LIP

A

Aerobic Glycolysis

29
Q

Benefits of high Altitude training

A

RBCs
Blood Oxygen
Haemoglobin

30
Q

Aerobic Training Leading to increased LIP

A
  • More mitochondria in muscle means greater use of oxygen for energy so can work aerobically for longer
  • Body becomes more efficient at utilizing oxygen
  • Allows athlete to work at increased pace and lower HR
31
Q

Reactivity

A

Reacting to a stimulus by changing behaviour

32
Q

How many mets is prolonged PA

A

7+

33
Q

Plyometrics

A

Increases muscular power by first stretching a muscle then contracting it in shortest possible time

34
Q

Muscular Chronic Anaerobic adaptations

A
  • Increase ATPase
  • Hypertrophy
  • Increased motor unit recruitement
  • Increased speed of contraction
  • Increase size and strength of connective tissues
35
Q

Tapering

A

Reduction in training while maintaining similar intensity

36
Q

Underarousal leads to being

A

lethargic, disinterested

37
Q

Overarousal leads to being

A

Nervous, anxious, having muscle tension

38
Q

Active Recovery

A

Involves low intensity activity to keep blood flow and oxygen levels elevated
