Interval training is a method of training where high-intensity work is alternated with periods of rest or low-intensity activity. This helps improve both aerobic and anaerobic fitness by challenging the body with intense bursts of effort followed by recovery periods.
Step 1: Analyzing each option.
- (A) Continuous Training: Incorrect. Continuous training involves steady, long-duration exercise without rest intervals.
- (B) Interval Training: Correct. This is the method described in the question, involving high-intensity bouts followed by rest or low-intensity activity.
- (C) Fartlek Training: Incorrect. Fartlek training is similar to interval training but less structured, with changes in intensity and pace.
- (D) Circuit Training: Incorrect. Circuit training involves a series of exercises performed in a sequence, with minimal rest between them, but it does not specifically focus on high-intensity work followed by rest.
Step 2: Conclusion.
The correct answer is (B), interval training, as it is defined by alternating high-intensity work with rest or low-intensity periods.
Final Answer:} Interval Training.
