Threshold pace意思

"Threshold pace" or "threshold running" is a term used in athletics, particularly in middle and long-distance running, to describe a pace that can be maintained for an extended period without leading to exhaustion. This pace is also known as the lactate threshold or VO2 max pace.

The lactate threshold is the point during exercise where lactate production in the muscles exceeds the body's ability to remove it, leading to a rapid buildup of lactate in the blood. This buildup can cause fatigue and limit the amount of work an athlete can perform. Threshold pace training helps to increase an athlete's lactate threshold, allowing them to run at a faster pace before reaching exhaustion.

VO2 max pace is the fastest pace that can be maintained for 30 minutes without fatigue. This pace is typically slower than the lactate threshold pace but is still a challenging workout for most runners.

Threshold pace workouts are an important part of a runner's training program, as they help to improve endurance, speed, and overall race performance. Common threshold pace workouts include tempo runs, interval training, and long runs at a steady pace.
