Is lactate threshold different for different activities and/or muscle groups?

Asked by: David Alam

We hypothesize no significant difference between lactate and ventilation derived thresholds in small muscle group exercise and that these thresholds can be verified by lactate steady-state tests.

Why is lactate threshold differences between the two athletes?

It varies depending on the specific activity, since the amount of oxygen that can be transported and utilized for different activities may vary. So an athlete’s VO₂ max will be different for running versus cycling. It will also vary throughout the training and competitive season.

Does lactate threshold increase with exercise?

Increase Weekly Running Mileage
It’s these cellular changes ultimately increase your lactate threshold, and allow you to run faster for longer. In many cases, runners are simply not running enough to develop their aerobic capacity, the foundation upon which all other aspects of running fitness are built.

What determines lactate threshold?

There are a few different ways that you can determine your lactate threshold (LT) without going to a lab for testing: Using an online pace calculator to estimate your LT based on your fitness level and recent race times (this is the easiest method). Estimate your LT using your heart rate and the Karvonen formula.

What is the difference between lactate threshold 1 and lactate threshold 2?

LT1 is defined as the lowest intensity at which there is a sustained increase in blood lactate concentration above resting values ¹. The second lactate threshold, also known as LT2 or maximal lactate steady state (MLSS) is used to demarcate zone 2 and 3.

Does Hiit increase lactate threshold?

Results: Only the HIIT group achieved improvements in peak power/velocity (+6.4%, P < 0.001) and peak lactate (P = 0.001) during the MART/MACT, while, unexpectedly, in none of the groups the performance at the established lactate concentrations (4, 6, 10 mmol·L⁻¹) was changed (P > 0.05).

Can you change your lactate threshold?

Interval running is a great way to increase your lactate threshold. With interval training, you repeatedly cover a set distance while running at your top speed, surpassing your lactate threshold, before taking a break to recover between runs. For example, you might choose to run 400 metres around a track at top speed.

Can you run a marathon at lactate threshold?

Generally the speed where you maintain 2 mmol/l/kg of bodyweight blood lactate levels (called the Aerobic Threshold or AeT) will be what you can maintain for the marathon.

Is it better to have a higher or lower lactate threshold?

The more work you can do before reaching lactate threshold, the better. If the pace you can hold at your lactate threshold is higher than the pace your competitor can hold at his or her lactate threshold, you go faster, reach the finish first, and win.
