Key result
A 150% W(max) bicycle test until exhaustion led to greater lactate accumulation (+9.3 mmol/L) and vasodilatation than lower intensity tests, but blood pressure was maintained.
Why the study?
Does exercise intensity affect post-exercise lactate accumulation and haemodynamics in athletes?

p-value: p=> 0.05
Higher intensity exercise yields greater lactate accumulation and vasodilatation, but compensatory cardiovascular mechanisms successfully prevent a drop in blood pressure.
No takes yet. Share an insight, caveat, or question.
High-intensity exercise may augment post-exercise vasodilation without hypotension in athletes; leaves open relevance to clinical populations.
Crisafulli et al. (2006) studied Athletes. 150% W(max) bicycle test vs. 130% W(at) and 70% W(at) bicycle tests was evaluated on Increase in blood lactate concentration at the 9th minute of recovery (p=> 0.05). A 150% W(max) bicycle test until exhaustion led to greater lactate accumulation (+9.3 mmol/L) and vasodilatation than lower intensity tests, but blood pressure was maintained.
