Concept Definition Measure/units
Energy Ability to perform work or put mass into motion Joules (J)
Work Ability to apply force over a distance: Joules (J) or Newtons (N)
Work = force(N) x Distance moved (m)
Power Rate at which work can be done Watts (W)
Power = work/time = (Nxm)/time
PC = P + C + E
ADP + Pi = ATP ATP = ADP + Pi + E

ENERGY SYSTEM & ADVANTAGES DISADVANTAGES
Training
adaptations
ATP/PC Doesn't require oxygen Only small amounts of ATP and PC
Anaerobic training PC stored in muscle cell = readily stored in muscles and cells
overloads system = accessible and available 1 PC resynthesises 1 ATP = very low
increase in muscle Simple/small compound = quick yield

ANAGRAM PRINCIPLE Definition/considerations
If training too much = muscular fatigue/overuse joint/ligament/tendon injuries &
M Moderation
for too little exercise = lack of adaptation.
R Reversibility Adaptations from training are reduced or lost when training is reduced or stopped
1. The individual, different rates of adaptation ­ this needs to be considered
due to genetic variations

TRAININ TRAINING OBJECTIVES
G ZONES
(%)
60 fat burning/re-energise glycogen stores
70 develop oxygen transportation systems
80 improve lactic acid threshold
85 lactic threshold
90+ speed
TRAINING METHOD
Continuou Steady state, sub- maximal work (typically running, cycling, swimming, rowing).
s Prolonged period of time ­ minimum 20-30 mins.
HR should be above the Critical Threshold ­ 55 - 60% of max (using the Karvonen method).
The % will change depending on the individual up to approx. 80%.…read more
