The Effect of Blinded Hydration State on Thermoregulation and Performance in Male Cyclists
… and hypohydrated (DEH-NT) conditions. In both trials, thirst was matched by drinking 25 mL every 5 min. In the EUH-NT trial sweat losses were fully replaced via the NG tube. Following the 2 hours of steady state, the cyclists completed a 5-kilometer cycling time trial at 4% grade. Study 2: …

The role of supplementary calcium in submaximal exercise and endurance performance.
… during endurance events (25 and 10 mile cycling time trials (TT)) in highly trained athletes. Results from these studies indicate that following calcium supplementation there was a meaningful improvement in power output (PO) (~4%) during the 25TT and ~2.7% in 10TT with corresponding better …

The psychophysiological regulation of pacing behaviour and performance during prolonged endurance exercise
… in 70-km individual and head-to-head competition time trials against a performance matched opponent. Sensory constructs were primarily associated with regulation of pacing behaviour. Affective and cognitive constructs acted as context-dependent modifiers and were primarily associated with …

Factors related to cycling performance
… was to determine if results from field tests (time-trials and a Conconi incremental test) are related to performance in mass-start long-distance bicycle races. The second goal was to investigate inter-relationships among field test variables. The testing variables measured were critical …

The regulation of exercise performance by a complex anticipatory system
… ten trained cyclists performed 20 km cycling time-trials in hot (35°C) and cool (15°C) conditions. The power output was reduced in the heat despite core temperatures that were sub-maximal and not different from those measured in the cool condition. Significantly, the reduction in power output …

THE EFFECT OF GROUP SIZE ON SYNCHRONY AND THE SYNCHRONY EFFECT
… 2011), it has only incorporated small group trials. Additionally no previous literature has investigated endorphin level subsequent to the immediate termination of exercise. The current study examined the effect of group size on the magnitude of the synchrony effect and explore the length of …

Visual Information Acquisition, Decision-making, Pacing and Performance during Time Trial Cycling
… information acquisition patterns during cycling time trials (TT). The first study found experts looked at primary information longer than novices during 10 mile TTs, with speed being the primary information source for experts, and distance was the primary information source for novices. A …

Training load metrics and responses of flatwater, ocean and river marathon kayakers in preparation for competition
… a minimal effect on the psychometric measures. Time trials are an effective performance measure where course environmental impacts can be mitigated. Conclusions: At present, there are practical, non-aversive metrics that provide valuable insights into various aspects of kayak training, including …

The Effects of Prolonged Bouts of Exercise and Acute Ischemic Preconditioning on Cardiac Biomarker Release
… other participants had no detectable hs-cTn in trials in week 0 and 1. At week 12 one participant (different to the person in week 0 and 1) had elevated hs-cTnI post-exercise (25 and 38 ng/l). NT-proBNP levels rose with exercise in all trials but peaked earlier in trial 1 and demonstrated great …
