How does interval training affect an individual's anaerobic threshold?

Interval training plays a pivotal role in increasing an individual's anaerobic threshold. When engaging in this type of training, individuals alternate between high-intensity bursts of exercise and periods of lower-intensity recovery. This method pushes the body to work harder than it typically would during steady-state cardio.

As a result, the body adapts to higher levels of lactic acid accumulation and learns to clear it more efficiently. Over time, consistent interval training enhances the muscles' ability to perform at higher intensities before fatigue sets in, thereby raising the anaerobic threshold. This translates to improved performance, allowing individuals to exercise at higher intensities for more extended periods without experiencing a drop in performance or the negative effects of lactate buildup.

The assertion that interval training has no significant impact is inaccurate because it downplays the physiological changes that occur due to this training method. Similarly, stating that it decreases or equalizes aerobic and anaerobic thresholds does not reflect the adaptive responses evidenced in well-structured interval training programs. Instead, increased anaerobic threshold is a widely recognized benefit of incorporating interval training into a fitness regimen.
