Blood lactate response to physical exertion using a treadmill for middle distance runners practicing track and field

The study aims to:identifying the impact of physical exertion using a treadmill (via the Sharkey test) on blood lactate levels in a sample of middle-distance runners. The current study addressed the following question: What is the impact on blood lactate levels due to physical exertion using a treadmill in a sample of track and field athletes? The researchers hypothesized significant differences in blood lactate levels between pre-and post-tests. The descriptive method was used for its suitability to the nature of the current research. The sample consisted of 9 athletes specialized in middle-distance running (800m - 1500m), representing the Nineveh Governorate track and field team. They were intentionally selected based on good health, high athletic performance, and being non-smokers. The results showed significant differences in blood lactate levels after exertion with a probability value of 0.001. The researchers concluded that physical exertion using a treadmill can cause changes in blood lactate levels.
