Abstract
This study examined the effect of time of day (TOD) on physical performance, and physiological and perceptual responses to a 10-km cycling time trial (TT<sub>10km</sub>). Twelve physically trained subjects (20.3 ± 1.2 years, 74.3 ± 7.4 kg, 179.7 ± 5.5 cm) completed, in a randomized order, a TT<sub>10km</sub> in the morning and in the evening. Intra-aural temperature (IAT) was measured at rest and following the TT<sub>10km</sub>. Completion time, power output (PO), rating of perceived exertion (RPE), heart rate (HR), minute ventilation (V̇E), oxygen uptake (V̇O<sub>2</sub>), carbon dioxide production (V̇CO<sub>2</sub>) and respiratory exchange ratio (RER) were assessed every km during the TT<sub>10km</sub>. Blood lactate concentration [La] and blood glucose concentration [Glu] were assessed before, during and immediately after the TT<sub>10km</sub>. Faster completion time (Δ = 15.0s, p = 0.03) and higher IAT (Δ = 0.33°C, p = 0.02 for pre-TT<sub>10km</sub>) were obtained in the evening compared to the morning with a significant correlation between Δ completion time and Δ IAT at post-TT<sub>10 km</sub> (r = -0.83, p = 0.04). V̇O<sub>2</sub>, [La] and [Glu] increased significantly during both test sessions (p < 0.001) with higher values in the evening compared to the morning (p = 0.015, p = 0.04, p = 0.01, respectively). However, the remaining parameters were found to be only affected by the TT<sub>10km</sub> (p < 0.001). The TT<sub>10km</sub> generates a higher V̇O<sub>2</sub> and higher [La] and [Glu] responses, contributing to a better cycling performance in the evening compared to the morning. The similar magnitude of the TOD effect on completion time and IAT at post-TT<sub>10km</sub> confirms that core temperature is one of the underlying factors contributing to the diurnal variation in physical performance.

Completion time, power output (PO), rating of perceived exertion (RPE), heart rate (HR), minute ventilation (V̇E), oxygen uptake (V̇O2), carbon dioxide production (V̇CO2) and respiratory exchange ratio (RER) were assessed every km during the TT10km. Blood lactate concentration [La] and blood glucose concentration [Glu] were assessed before, during and immediately after the TT10km. Faster completion time (Δ = 15.0s, p = 0.03) and higher IAT (Δ = 0.33°C, p = 0.02 for pre-TT10km) were obtained in the evening compared to the morning with a significant correlation between Δ completion time and Δ IAT at post-TT10 km (r = -0.83, p = 0.04). V̇O2, [La] and [Glu] increased significantly during both test sessions (p < 0.001) with higher values in the evening compared to the morning (p = 0.015, p = 0.04, p = 0.01, respectively).
