How does regular training affect lactate threshold relative to VO2 max?

• A. No change with training.
• B. The lactate threshold shifts to a higher percentage of VO2 max with training.
• C. The lactate threshold lowers with training.
• D. The threshold is determined by age.

Answer: (B)

Regular endurance training boosts the body's ability to use lactate as a fuel, increasing oxidative capacity and lactate clearance. This means you can sustain a higher intensity before lactate starts to accumulate rapidly. In terms of VO2 max, the lactate threshold moves to a higher percentage of that max, so you’re able to work harder before hitting a problematic rise in lactate. This shift happens because muscles gain more mitochondria, better capillarization, and more effective lactate transport and oxidation. Since VO2 max itself often increases with training, the same absolute workload represents a larger percentage of VO2 max after training. So the lactate threshold relative to VO2 max increases with regular training. It doesn’t stay the same or decrease, and it isn’t set by age.
