Q
Training principles
A
- specificity
- individual differences
- progressive overload
- reversibility
- variance
- over-training
25
Specificity
Training the areas of fitness used in your sport and replicating the movements used in your sport
- replicate the sport
26
Individual differences
- training needs to be specific to the individual and also the sport
- vary for the person
27
Progressive overload
- applying physical stress to the body
Applying it
E.g. regular lifting of ‘heavy’ weights will result in the muscles getting larger (hypertrophy)
- as the body adapts, training overload should be increased in a controlled/ gradual fashion
F- frequency- how many?
I- intensity- how difficult?
T- time- how long?
T- type- which training activity?
- FITT principle
28
Reversibility
- process of losing fitness soon after stopping regular training or exercise
- going backwards (decline in performance)
- adaptation of no overload
Could be due to:
- injury
29
Variance
- seeks to prevent tedium
- repeating the same drills, week in and out will result in lowering motivation
- prevent boredom
30
Describe the importance of anaerobic capacity in sports performance?
- describes the volume or amount of the anaerobic system
- specifically the ATP-PC system and the anaerobic glycolic system
- these systems can provide high intensity energy (ATP resynthesis) for up to 3 minutes
- capacity describes how long this system can sustain energy for
- e.g. netball: regardless of playing position, there will be multiple high intensity sprints during the match.
- cumulatively these will engage the anaerobic systems
- a player with a large anaerobic capacity can sustain a frequency of these sprints beyond a lesser player
- this will be because of higher quantities of substrates such as PC; a greater tolerance of lactate and hydrogen ions, or a highly efficient short term recovery via EPOC
- In the later stages of a netball match, when others are beginning to feel fatigue, and an inability to continue these high intensity sprints
- high anaerobic capacity supports the continuation of this
31
Overtraining

48
Factors influencing flexibility
- age
- gender
- physical exercise
- flexibility
49
What does flexibility tend to do with age?
- decline due to the stiffening of connective tissues and reduced collagen turnover
50
Types of stretches
Static- still stretches
Dynamic- has movement included
Ballistic- bouncing movement. That accompanies the stretch
Passive- needs a partner included
PNF- proprioceptive neuromuscular facilitation- can turn stretch reflex off so muscles are relaxed
51
Muscle spindle
- detects muscle movement (proprioceptor)
- when it lengthens- causes contraction of a few fibres in the centre of the medulla (intra fusal)
- this is called the stretch reflex
- (not helpful when you want to ‘stretch’ a muscle)
52
Can the stretch reflex be turned off?
- yes
- Golgi tendon organ
- located in tendons
- monitors tension
- when under contraction/ tension it become stimulated
- desensitizes the stretch reflex
53
PNF
- muscle is stretched to it’s limit
- Isometric contraction takes place stimulating the Golgi tendon organ
- this deactivates the stretch reflex
(Proprioceptive neuromuscular facilitation
- additional stretch is then completed
54
Problem of PNF
- Stretching a muscle incurs a reflex
- detected by muscle spindle apparatus
- causes contraction of intra fusal fibres
55
Macrocycle
Identifies the larger long term objective of the training 12 months usually
56
Mesocycle
Identifies the shorter period to achieve short term goals 4-8 weeks
57
Micro cycle
Identifies the individual training regime 7 day period
58
Benefits of periodisation
Prepare an athlete for optimal improvement
To prepare an athlete for a definite climax to the season
To prepare an athlete for the main competitions in their season
59
Linear periodisation
Various major training stimuli are segregated from eachother
60
Non linear periodisation
Attempts to address all of the shortcoming by mixing together the various major training stimuli
61
Preparation period
- general conditioning in early phases (usually endurance based)
- specific training follows with progressive overload
62
Competition period
- maintaining fitness
- some reduction in the volume of training
- allowances for recovery
- tapering for specific peaking
63
A recovery period
- proper opportunity for relaxation and recuperation
64
Partial pressure
- pressure of a gas within a mixture of gases
- partial pressure of o2 within air at ‘sea level’ is 160mmHg
65
Diffusion of o2
PO2 in alveoli= 105mmHg
PO2 in the alveolar capillaries= 40mmHg
- difference between these two pressures= 65 (known as the pressure gradient)
- pressures will attempt to equalise moving from high to low diffusing across the membrane
- result is that the blood in the lung capillaries gains O2
66
High altitude
- low total air pressure
- lower po2 leads to less absorption of O2 with haemoglobin
- smaller gradient leads to slower diffusion
- the red blood cells contain haemoglobin (Hb) an iron based pigment
- when O2 combines it forms oxy-haemoglobin (HbO2)
- Haemoglobin has a very high affinity for O2
67
Acclimatization.
- adapting to altitude climate
68
Changes during acclimatization
- increase in blood haemoglobin
- increases in myoglobin
- increase in number of mitochondria
- capillarisation
69
Impacts of low air pressure
1. Smaller diffusion gradient in the alveoli
- slower gaseous exchange
- less o2 moves into the blood
2. Lower saturation of o2 within haemoglobin (in the lungs)
- less o2 is transported to the working muscles
70
Thermoregualtion
The body’s mechanism for managing and controlling its internal temperature
71
Factors affecting temperature
- exercise
- clothing
- weather
- body fat
- water/ sweating
72
Where is the thermoregulation gene situated?
In the hypothalamus
- it is sensitive to the temperature of the blood, and acts as a thermostat for the body
73
Hypothermia
- body temp below 35 degrees Celsius
74
Mechanisms to increase temperature
- shivering
- blood redirected towards the centre of body
- ‘goose bumps’/ hair stands up
75
Hyperthermia
Body temperature above 39 degrees Celsius
76
Mechanisms to reduce temperature
- sweating (could lead to dehydration)
- blood redirected to body surface
77
Sweating
- evaporation provides the major physiological defence against overheating
- approx 3 million sweat glands distributed throughout the surface of the body
- sweat doesn’t cool the skin, evaporation cools the skin
78
Consequences of dehydration
- decrease sweating ability
- increase in H.rate
- Increase in body temp
- electrolyte loss
79
What is the most important factor that determine show much O2 combines with haemoglobin?
- partial pressure of O2 in the environment where the red blood cell (haemoglobin) is located
