Prolonged cycling reduces power output at the moderate-to-heavy intensity transition.

ABSTRACT:

Purpose

To determine the effect of prolonged exercise on moderate-to-heavy intensity transition power output and heart rate.

Methods

Fourteen endurance-trained cyclists and triathletes took part in the present investigation (13 males, 1 female, V·O₂peak 59.9 ± 6.8 mL^.kg^-1.min^-1). Following a characterisation trial, participants undertook a five-stage incremental step test to determine the power output and heart rate at the moderate-to-heavy intensity transition before and after two hours of cycling at 90% of the estimated power output at first ventilatory threshold (VT₁).

Results

Power output at the moderate-to-heavy intensity transition significantly decreased following acute prolonged exercise when determined us
