‘Lactate threshold’ is a crucial concept in sports science and exercise physiology. Let’s break it down:
Definition: The lactate threshold is the exercise intensity at which lactate begins to accumulate in the blood at a faster rate than it can be removed.
Part of speech: Noun phrase
Pronunciation: /ˈlæk.teɪt ˈθreʃ.həʊld/
As a specialized term in sports science, understanding ‘lactate threshold’ can be valuable for IELTS candidates, especially those dealing with topics related to fitness, athletics, or physiology.
