Purpose: To describe pacing strategy and competitive behaviour in elite-level cyclo-cross races. Methods: Data from 329 men and women competing in 5 editions (2012-2016) of UCI Cyclo-cross World Championships were compiled. Individual mean racing speeds from each lap were normalised to the mean speeds of the whole race. Lap-by-lap and final rank...

Purpose: Maximal oxygen uptake (V˙O2max) is a key determinant of endurance performance. Therefore, devising high-intensity interval training (HIIT) that maximizes stress of the oxygen-transport and -utilization systems may be important to stimulate further adaptation in athletes. The authors compared physiological and perceptual responses elicited...

This study aimed to describe the racing and training demands of the Cape Epic. Six male mountain bike riders (age: 39±7 years, height: 181±3 cm, body mass: 78.7±8.1 kg) trained for 4.5 months and took part in the Cape Epic. Training and racing data (prologue, stage 1, and 2) were analysed, and riders were tested in the laboratory on three distinct...
Article

Purpose: To compare methods of relative intensity prescription for their ability to normalise performance (i.e., time to exhaustion), physiological, and perceptual responses to high-intensity interval training (HIIT) between individuals. Methods: Sixteen male and two female cyclists (age: 38 ± 11 years, height: 177 ± 7 cm, body mass: 71.6 ± 7.9...

Purpose To investigate the influence of exercise intensity normalisation on intra- and inter-individual acute and adaptive responses to an interval training programme. Methods Nineteen cyclists were split in two groups differing (only) in how exercise intensity was normalised: 80% of the maximal work rate achieved in an incremental test (%Ẇmax) vs....

Objectives This study was designed to quantify inter- and intra-individual variability in performance, physiological, and perceptual responses to high-intensity interval training (HIIT) prescribed using the percentage of delta (%Δ) method, in which the gas exchange threshold and maximal oxygen uptake (V̇O2max) are taken into account to normalise re...

This letter critiques the data analysis of a study investigating peak oxygen uptake responses to cycling and running sprint interval training (Digby et al., 2023 J Strength Cond Res, 37(4), e313-e316). While the study effectively demonstrates the specificity principle in the context of sprint interval training, concerns arise regarding the methodol...
Article
Full-text available
Varied-intensity work intervals have been shown to induce higher fractions of maximal oxygen uptake during high-intensity interval training compared with constant-intensity work intervals. We assessed whether varied-intensity work intervals combined with intermittent vibration could further increase cyclists' fraction of maximal oxygen uptake to po...

The aim of this study was to describe the pacing during a 6-h ultramarathon (race 1) and to investigate whether a slow-start affects performance, running kinematic changes, ratings of perceived exertion (RPE) and fatigue (ROF) (race 2). After a critical speed test, participants completed two 6-h ultramarathons. Race 1 (n = 16) was self-paced, where...

Purpose: There are several published equations to calculate energy expenditure (EE) from gas exchanges. We assessed whether using different EE equations would affect gross efficiency (GE) estimates and their reliability. Methods: Eleven male and three female cyclists (age: 33 ± 10 years; height: 178 ± 11 cm; body mass: 76.0 ± 15.1 kg; maximal ox...

Introduction The Absa Cape Epic is an 8-day mountain bike race involving a total distance in excess of 650 km with over 13000 m of climbing, suggesting athletes require targeted ultra-endurance training to develop the necessary capabilities. Despite attracting the world's best mountain bikers, training and racing demands are yet to be described. M...

Functional threshold power is defined as the highest power output a cyclist can maintain in a quasi-steady state for approximately 60 min (FTP60). In order to improve practicality for regular evaluations, FTP60 could theoretically be determined as 95% of the mean power output in a 20-min time trial (FTP20). This study tested this assumption and the...

Objective.—To investigate whether a slow-start affect overall performance and running mechanics during 6-hour ultramarathon races. Methods.—After a critical speed (CS) test, 10 ultra-runners (age: 40.5 ± 11.0 years, CS: 3.9 ± 0.5 m·s−1, D’: 119.9 ± 41.0 m) completed two 6-hour races on a 400-m track, 4 weeks apart. In the second race, they were req...

Conference Paper
Full-text available
Introduction Background: Performance-assessment tests are often used to verify the efficacy of cycling training programs or experimental interventions in scientific studies. Previous research has shown high reliability of mean power output (POmean) during field timetrials of different courses, such as 36- and 40-km flat, 1.4-km uphill and 4- and 20...

Purpose: To describe pacing strategy in a 24-h running race and its interaction with sex, age group, athletes' performance group and race edition. Methods: Data from 398 male and 103 female participants of 5 editions were obtained based on a minimum 19.2-h effective-running cut-off. Mean running speed from each hour was normalised to the 24-h me...

Background: Recently, the use of a counterweight during one-legged cycling has been advocated as a training methodology to enhance the metabolic and oxidative potential of skeletal muscle. However, to date, no study has investigated whether training using either the dominant or the non-dominant leg affects the physiological response to a bout of ex...

This study aimed to assess the relationship between an uphill time-trial (TT) performance and both aerobic and anaerobic parameters obtained from laboratory tests. Fifteen cyclists performed a Wingate anaerobic test, a graded exercise test (GXT) and a field-based 20-min TT with 2.7% mean gradient. After a 5-week non-supervised training period, 10 o...

Background: A field test which can be easily integrated into the training routine of cyclists to monitor performance changes is valuable. It has been demonstrated that when performing a 20-min outdoor time trial (TT), cyclists produce approximately 5.4% higher mean power output during uphill than flat routes (Nimmerichter et al., 2012: European Jou...
