Question

Interval training load depends on:
A. Load volume,
B. Heart rate,
C. Load Intensity,
D. Lactic acid concentration

• A. A and B only
• B. A and C only
• C. B and C only
• D. B and D only

Hint:

Remember, while physiological measures like heart rate and lactic acid concentration are important for monitoring training sessions, they do not directly define the training load.

Answer 1

The Correct Option is C

Step 1: Concept
Interval training is a form of high-intensity exercise that alternates between periods of intense activity (work intervals) and rest or low-intensity recovery. The load during interval training depends on several factors, including the volume and intensity of work performed.

Step 2: Meaning
Load volume refers to the total amount of work done in terms of time or distance. Load intensity is the level of effort exerted during each work interval. Heart rate and lactic acid concentration are physiological measures that can indicate the intensity but do not directly define the load itself.

Step 3: Analysis
A (Load volume): This factor is crucial as it determines how much total work is done, which contributes to the overall training load. B (Heart rate): While heart rate can be an indicator of intensity and thus indirectly related to load, it does not directly define the load itself. It is more a measure of physiological response rather than the actual load applied. C (Load Intensity): This factor is essential as it defines how hard each work interval is performed, which significantly impacts the training load. D (Lactic acid concentration): Similar to heart rate, lactic acid concentration indicates metabolic stress but does not directly define the load. The correct answer should include both load volume and load intensity because these factors directly determine the total amount of work done during the interval training session. Heart rate can be a useful indicator but is not a defining factor for the load itself.

Step 4: Conclusion
Interval training load depends on the total amount of work performed (load volume) and how hard each work interval is performed (load intensity). Final Answer: (C)
