4
Q

individual physiological make up

A

dependent on 4 energy systems:
.respiratory syst ability to consume O2 (lung size etc)
.heart to transport O2 (heart size, SV etc)
.vascular syst to transport O2
.muscles to use O2 including cellular factors (myoglobin, mitochondria etc)

contribution of these allows athletes to increase aerobic capacity

Q

genetics/heredity

A

.% of fibre type
.individuals genetic adaptation to training
.can amount for 1/2 VO2 max

only determines potential - still have to train to reach these levels

Q

training

A

.max levels of aerobic capacity can be reached after 8-19 months of heavy endurance training
.specificity helps target endurance

7
Q

age

A

VO2 max decreases 1% per year due to decrease in energy systems
2 main causes:
CV - max hr, CO (Q), SV decrease due to reduced elasticity of the left ventricle
Respiratory - lung volume including max VE decrease due to reduced elasticity of lungs

8
Q

gender

A

.VO2 max levels 20-25% lower in females due to smaller body size
smaller lung volume = lower O2 intake
smaller heart = higher RHR - lower Q, SV

Q

VO2 max test

A

.exercising on a treadmill/bike at an intensity that increases every few minutes until exhaustion
.designed to achieve a maximal effort.
.obtain the individual’s MHR + RHR to develop a precise target heart rate range.

Q

multi stage fitness test

A

.athlete runs back and forth 20m, making sure to reach each end as the beep sounds
.each level becomes harder
.go till they either fail to reach before beep 3 times, or quit

Q

12 min Cooper run pros

A

easy to conduct

can test lots at once

17
Q

12 min Cooper run cons

A

practise and pacing required
highly influenced by motivation
not reflective for rowers/cyclists

18
Q

Queens College step test

A

.athletes step up and down at rate of 22 (girls) or 24 (boys) steps per min
.lasts 3 min
.measure HR immediately after (for 15s then times 4)

19
Q

Queens College step test pros

A

minimal equipment
quick
can be self administered

20
Q

Queens College step test cons

A

.taller individuals at an advantage
.assumes running and stepping has same energy cost (results based off of running)
.can lie about hr to seem fitter

21
Q

periodisation

A

organisation of training into blocks

aims to develop an athlete to achieve a skill/physiological peak at the correct time

22
Q

macrocycle

A

long term plan/goal

typically lasts 1 year

23
Q

mesocycle

A

medium term plan/goal

typically lasts 4-16 weeks

24
Q

microcycle

A

short term plan/goal

typically lasts 1 week

25
Q

unit

A

short period/session of training with a particular aim e.g focus on one aspect of performance

26
Q

meso-cycle 1.1

A

basic event phase
pre season
characterised by development of all round fitness

27
Q

meso-cycle 1.2

A

specific event phase
pre season
slowly increase training intensity
focus on fitness components

28
Q

meso-cycle 1.3

A
Pre-competition phase
pre season
focus on integrating 1.1 and 1.2
less training, but more intense
practise games incorporated
29
Q

meso-cycle 2.1

A
.maintenance phase
.competition season
maintain fitness levels
lower intensity
adequate rest
30
Q

meso-cycle 2.2

A

.monitoring and recovery phase
.competition phase
monitor signs of burn out/over training
increase recovery time as season ending

31
Q

meso-cycle 3.1

A

rest/recovery phase 1
transition/off season
initial period of rest/low level active recovery
treat injuries

32
Q

meso-cycle 3.2

A

rest/recovery phase 2
transition/off season
gradual build up of low level training to prepare for pre season

33
Q

Physiological adaptations vascular system

A

.Increased elasticity of arterial walls (improves vascular shunt mechanism)
.Increased RBC/haemoglobin - increase o2 carrying capacity
.Increased capillarisation

34
Q

A
Hypertrophy of ventricle walls
Increased sv
Increased edv
Increase stretch of v walls 
Decrease rhr - bradycardia
35
