The aim of this study was to investigate if drinking ad-libitum can counteract potential negative effects of a hypohydrated start caused by fluid restriction during a 40-km time trial (TT) in the heat. Twelve trained males performed one 40-km cycling TT euhydrated (EU: no water during the TT) and two 40-km cycling TTs hypohydrated. During one...

The goal of this study was to investigate the effects of different durations of skin temperature manipulation on pacing patterns and performance during a 15-km cycling time trial. Nineteen well-trained men completed three 15-km cycling time trials in 18┬░C and 50% relative humidity with 4.5-km (short-heat), 9.0-km (long-heat) or without (control)...

This study examined the effect of active pre-warming on speed and quality of performance during simulated firefighting exercise. Twelve male firefighters performed two trials in counterbalanced order. They were either pre-warmed by 20-min cycling at 1.5 Watt kg-1 body mass (WARM) or remained thermoneutral (CON) prior to a simulated firefighting...

In de warme Australische woestijn wordt jaarlijks een wedstrijd gehouden wie het snelst is met een auto op zonne-energie. De TU Delft is daarin een topper en wil ook de coureurs optimaal voorbereiden. In dit artikel wordt onderzocht hoe sterk de lichaamstemperatuur oploopt en hoeveel vocht wordt verloren tijdens een nagebootste race in de hitte....

Skin temperature has been suggested as a relevant physiological signal for the anticipatory and feedback control of work rate during self-paced exercise [1, 2]. However, a sudden extreme skin temperature elevation did not affect pacing during a 7.5-km cycling time trial [3]. Possible explanations for the discrepancy in these results are the...

Aerobic exercise performance is seriously compromised in the heat. Possibly, a high skin temperature causes a rating of perceived exertion (RPE)-mediated decrease in exercise intensity. The purpose of this study was to determine the effect of skin temperature on power output during a 7.5-km cycling time trial. Thirteen well-trained male subjects...

Tijdens de marathon van Eindhoven op 11 oktober 2009 er door TNO onderzoek gedaan naar een mogelijk positief effect van het koelen van hardlopers op de loopsnelheid. Het is namelijk bekend dat de effici├źntie van een hardloper afneemt als hij het warm krijgt. Kunnen koude douches dit voorkomen?
