PDHPE HSC; CORE 2 Factors Affecting Performance with
Questions and Answers

SIQ: How does training affect performance? - answerEnergy systems

Types of training and training methods

Principles of Training

Physiological adaptations in response to training

SDP: what are the 3 energy systems? - answerATP/PC

Lactic acid

Aerobic

ATP/PC system - source of fuel - answercreatine phosphate

ATP/PC - efficiency - answer1:1

ATP/PC - duration - answer10-15 secs

ATP/PC - cause of fatigue - answerInability to resynthesise

ATP/PC - by products - answerHeat

ATP/PC - Recovery rate - answer2 mins rest

ATP/PC - activities - answer100m sprint, shot put, weight lifting, high jump, golf swing, discus
throw

,Lactic acid system - source of fuel - answercarbohydrates and glycogen

Lactic acid system - efficiency - answerFast, 1:2, anaerobic glycolysis

Lactic acid system - duration - answer10 secs - 4 mins (intensity dependent)

Lactic acid system - cause of fatigue - answerLactic Acid build up, 'burn' (H+ ion build up acidosis
in working muscle)

Lactic acid system - by products - answerLactate

Lactic acid system - recovery rate - answer30 mins - 2 hours, lactate removal.

If insufficient oxygen is available to the working muscles, the pyruvate binds to pH-decreasing
hydrogen atoms, forming lactate --> transported to the liver to be metabolised and converted back
into glycogen.

Lactic acid system - activities - answer800m run, 200m swim

What is anaerobic glycolysis? - answerGlycogen --> glucose --> glucose broken down --> releases
energy for ATP resynthesis of 2 ATP + by product pyruvate.

Aerobic system - source of fuel - answercarbohydrates( when intensity increases towards and
above 70% of max HR), fat (when at rest), protein (in extreme cases when both other stores are
depleted)

Aerobic system - efficiency - answerSlow, 1:36, when using fat as the fuel, yield is even greater,
>400 ATP (however this requires excessive oxygen, so usually used at rest)

, Aerobic system - duration - answer2-6 hours

It takes at least 60 seconds for aerobic glycolysis to start providing energy, as the increased O2
demand has to be delivered via the cardiovascular system

Aerobic system - cause of fatigue - answerGlycogen and carbohydrate depletion

Neuromuscular and mental fatigue

Aerobic system - by products - answerCO2, H2O and heat

Aerobic system - recovery rate - answerHours to days (intensity dependent), replenish fuel stores -
athletes must eat adequate amounts of food to replenish stored. Eat 50-100g of carbohydrates
within 30 mins of ex.

Aerobic system - activities - answerMarathons, Triathlons, long distance swimming

SDP: Types of training - answerAerobic

Anaerobic

Strength

Flexibility

Types of aerobic training - answercontinuous

fartlek

circuit

interval

What does continuous training involve? - answerAn extended, predominantly steady-state
training session that lasts no less than 15-20 minutes. Used by lower level athletes and racing
endurance sports like rowing, cycling, distance running and swimming
