CSCS Periodization & Energy Systems

Question 1

What is the definition of a 'mesocycle' in traditional periodization planning?

Accepted Answer

A medium-length training phase of 3-6 weeks focusing on a specific biomotor quality

Answer

A single training session lasting 60-90 minutes

Answer

A weekly training block of 5-7 days

Answer

The entire competitive season from start to finish

Question 2

What is the approximate time for phosphocreatine (PCr) to be 50% resynthesized after maximal-effort exercise?

Accepted Answer

30 seconds

Answer

5-10 seconds

Answer

2-3 minutes

Answer

8-10 minutes

Question 3

The General Adaptation Syndrome (GAS) model proposes three stages of response to a training stressor. In the correct order, these are:

Accepted Answer

Alarm, Resistance, Exhaustion

Answer

Exhaustion, Resistance, Alarm

Answer

Alarm, Exhaustion, Resistance

Answer

Resistance, Alarm, Exhaustion

Question 4

What respiratory exchange ratio (RER) value indicates that carbohydrate is the exclusive fuel being oxidized?

Accepted Answer

RER = 1.00

Answer

RER = 0.70

Answer

RER = 0.85

Answer

RER = 1.10

Question 5

What is the key difference between an accumulation block and an intensification block in block periodization?

Accepted Answer

Accumulation uses high-volume lower-intensity training to build work capacity; intensification uses lower-volume higher-intensity training to convert work capacity to sport-specific performance

Answer

Accumulation uses high-intensity low-volume work; intensification uses high-volume low-intensity work

Answer

Both blocks use identical volume and intensity with only exercise selection differing between them

Answer

Accumulation blocks are used exclusively for endurance athletes; intensification blocks are only for strength athletes

Question 6

Which of the following best describes the difference between VO2max and lactate threshold as predictors of endurance performance in trained athletes?

Accepted Answer

Lactate threshold (as a percentage of VO2max) is generally a better predictor in trained athletes because it reflects the highest sustainable aerobic exercise intensity

Answer

VO2max is always the better predictor because lactate threshold remains constant with training

Answer

Both measures predict performance equally well regardless of athlete training status

Answer

VO2max directly measures lactate production, making lactate threshold measurement redundant
