Article
The present study examined (i) the magnitude of rate of torque development (RTD), and (ii) the between-day reliability of RTD at the start of a cycling sprint when sprint resistance, sprint duration, and the pedal downstroke were altered. Nineteen well-trained cyclists completed one familiarisation and three testing sessions. Each session involved...

Pacing profiles of 19 elite and sub-elite 200-m kayak athletes were examined through stroke-by-stroke analysis, using GPS/accelerometer methodology. Stroke rates and lengths were also quantified across multiple race segments. Whilst athletes reached peak velocity at between 40 and 60 m, it was not possible to determine specifically whether an all-o...

A road cycling sprint can be described as the acceleration which occurs toward the end of competitions in order to reach the finish line in front of other competitors. The ability to sprint in road cycling is important since most races are decided in either a head-to-head, small group, or mass sprint finish. Cycling velocity during sprints is impor...

Thesis
Endurance athletes typically spend the large majority of training (> 70%) at low intensities (i.e. below lactate threshold) coupled with short and intermittent bouts of high-intensity exercise or interval training (HIIT). Despite HIIT being a relatively small part of training in terms of duration, it has a substantial effect on the adaptations to e...

Prior exercise can negatively affect movement economy of a subsequent task. However, the impact of cycling exercise on the energy cost of subsequent running is difficult to ascertain, possibly because of the use of different methods of calculating economy. We examined the influence of a simulated cycling bout on running physiological cost (running...

Background: Peak velocity is likely to be an important factor in the outcome of road cycling sprints. Cycling velocity is dependent on the balance of power output and resistive forces including, aerodynamic drag (CdA), gravity, rolling resistance and mechanical inefficiencies (Martin et al. 2006). With air resistance known to present the greatest r...

In combat sports, athletes are divided into categories based on gender and body mass. Athletes attempt to compete against a lighter opponent by losing body mass prior to being weighed (i.e., 'weight-cutting'). The purpose of this narrative review was to explore the current body of literature on weight-cutting and outline gaps for further research....

We demonstrate that sleep is preceded by distal skin vasodilation in preterm nenoates and children, which may play a key role in facilitating sleep onset. It can be hypothesized that sleep propensity could be improved in neonates and children by mild manipulations of distal skin temperatures, as has been previously show effective in adults.

In the life of an athlete, and cyclists are no different, training accompanies and characterizes the person’s entire career, from youth to adulthood. Indeed, a good longitudinal training strategy is, together with a few other fundamental aspects described in this book, what takes a young cyclist from the playground to the Olympic Games. Training do...

INTRODUCTION: Performance of steady-state endurance exercise close to lactate threshold is reduced in substantially hot and cold environmental temperatures (TA), demonstrating an inverse U-shaped relationship between TA and endurance performance (Galloway and Maughan, 1997; Peiffer and Abbiss, 2011). Paradoxically, endurance athletes train a small...

Prior research indicates that providing participants with positive augmented feedback tends to enhance motor learning and performance, whereas the opposite occurs with negative feedback. However, the majority of studies were conducted with untrained participants performing unfamiliar motor tasks and so it remains unclear if elite athletes completin...

The relationship between patterns of change in skin temperature and sleep is well recognized. In particular, there is a rapid rise in distal skin temperature (Tdistal) and slower rise in proximal skin temperature (Tproximal) prior to sleep onset. The difference between Tdistal and Tproximal is known as the distal-proximal gradient (DPG). Rise in DP...

Introduction. Cycling power output may be influenced by rider specialisation (Sallet et al. 2006), topography (Vogt et al. 2007) and road gradient (Nimmerichter et al. 2012). However, little is known with regards to the maximal power output achieved by professional cyclists during competition. Therefore, the primary aim of this study was to examin...

Introduction It has recently been shown that pacing differs between time- (6 min) and distance-based (4km) cycling time trials (Abbiss et al., 2016). However, it is unclear if prior experience in time- and distance-based trials affects pacing, performance and perceptual responses. The aim of this study was to examine the influence of familiarisati...
