Key result
High intensity exercise during a 100m race primarily utilized anaerobic metabolism, with a non-lactic acid process and little change in muscle oxygen saturation in the first 7s.
Why the study?
High intensity exercise is an important factor to achieve the best exercise effect and is closely related to patient safety and rehabilitation, prompting investigation into its effects on cardiovascular response and metabolism.
What are the cardiovascular and metabolic responses to high intensity exercise in young male students?

What are the cardiovascular and metabolic responses to high intensity exercise in young male students?
High intensity sprint exercise relies heavily on early anaerobic metabolism and may reduce heart rate variability, suggesting the need for careful exercise load management to avoid arrhythmias.
No takes yet. Share an insight, caveat, or question.
Highlights early anaerobic dominance in youth sprints; leaves open links to heart rate variability or arrhythmia risk during high-intensity exercise.
Qing-zhong et al. (2021) conducted an observational in Healthy (n=50). High intensity exercise (100m run) was evaluated on Heart rate and blood oxygen parameters. High intensity exercise during a 100m race primarily utilized anaerobic metabolism, with a non-lactic acid process and little change in muscle oxygen saturation in the first 7s.
