Incorrect PE Questions Flashcards
V02 Max is the product
Cardiac Output and AV02 Difference
Training anaerobically can lead to an increase in the bodys….
Ability to buffer the metabolic bi-product build up
PNF Strecthing
Involves a static stretch followed by an isometric contraction or contract and relax sequence
Myoglobin
Carries oxygen molecules to muscle tissue
Benefits and harms of a Stimulant
Pros - Perception of fatigue - Alertness/sharpness -Aggressiveness Cons - Hypertension - Heart Attack -Tremor
2 Purposes of Active Recovery
- Accerlerate removal of blood lactate
- Replenishment of Phosphocreatine stores
- Removal of Waste products
- Reduce doms
Muscle contractions that produce the greatest force are
eccentric
Benefit of a massage
Improved relaxation and well being
FItness Tests for Muscular Power
Seated Basketball throw
Vertical Jump
Training method for agility
Aerobic based circut
Benefit and legal alternative to amphetimines (Stimulant
Benefit - Alertness
Alternative - Caffeine
How and what happens when LIP is increased
- Able to produce ATP aerobically at higher intensity
- Occurs from chronic adaptations such as increased mitochondria size and number, increased oxidative enzymes
EPO
- Naturally occurring hormone
- Is a synthetically injected substance that increases RBCs and hence the oxygen carrying capacity of blood as well as Hameoglobin levels
Intensity is
level of effort/exertion applied
Explain how dehydration affects an athletes ability to recover after intense exercise
- 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
Three mechanisms responsible for venous return
Muscle Pump- causes veins to be constricted
Respiratory Pump - pressure in thorax and abdomen
Vasocontriction
Anaerobic glycolysis system has a ___________ capacity
FInite Capacity
Physiological or Psychologicla Factors that are affected by SLeep
- ^ Stress or anxiety
- Decreased effective cognition
- Decreased performance
- Decreased Reaction Time
- Lack of motivation
- Increased recovery time
Important to be hydrated before a marathon becuase
- Able to combat sweat loss
- Able to maintain bodily fluid and is therefore at less risk of dehydration
Difference between absolute and relative VO2 Mx
Absolute does not take into account athletes body weight, Relative does
Eg- 100kg will have less relative VO2 max than someone weighing 70kg
Explain how anaerobic training and its chronic adaptations leads to faster times
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
Eccentric Contraction =
Lengthening
Concentric Contraction =
Shortens
Venous Return
Is the rate of blood flow back to the heart
Main Reasons for WADAs establishment
- Coordinate and Moniter
- To promote
- TO fight against doping in sport
Training anaerobically leads to
Lactate tolerance
Hyperbaric Chambers
Saturatio of oxygen through the body
Predominant energy system when working at LIP
Aerobic Glycolysis
Benefits of high Altitude training
RBCs
Blood Oxygen
Haemoglobin
Aerobic Training Leading to increased LIP
- 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
Reactivity
Reacting to a stimulus by changing behaviour
How many mets is prolonged PA
7+
Plyometrics
Increases muscular power by first stretching a muscle then contracting it in shortest possible time
Muscular Chronic Anaerobic adaptations
- Increase ATPase
- Hypertrophy
- Increased motor unit recruitement
- Increased speed of contraction
- Increase size and strength of connective tissues
Tapering
Reduction in training while maintaining similar intensity
Underarousal leads to being
lethargic, disinterested
Overarousal leads to being
Nervous, anxious, having muscle tension
Active Recovery
Involves low intensity activity to keep blood flow and oxygen levels elevated
