A methodology to study bike handling of cyclists during individual time trials (ITT) is presented. Lateral and longitudinal accelerations were estimated from GPS data of professional cyclists (n=53) racing in two ITT of different length and technical content. Acceleration points were plotted on a plot (g-g diagram) and they were enclosed in an elli...

Introduction: This study evaluates the power profile of a top-5 result achieved within World Tour cycling races of varying types, namely: flat sprint finish (FLAT), semi-mountain race with a sprint finish (SMsprint), semi-mountain race with uphill finish (SMuphill) and mountain races (MT). Methods: Power output data from 33 professional cyclists w...
Article

To optimise use of available resources, professional academies develop strategies to assess, monitor, and evaluate players as they progress through adolescence towards adulthood. However, few published reports exist using longitudinal study designs to examine performance throughout adolescence, and the transition from youth to professional soccer....
Article
Full-text available
This study analyses the influence of race category and result on the demands of professional cycling races. In total, 2920 race files were collected from 20 male professional cyclists, within a variety of race categories: Single-day (1.WT) and multi-day (2.WT) World Tour races, single-day (1.HC) and multi-day (2.HC ) Hors Catégorie races and single...
Article
Full-text available
Subjective and objective assessments may be used congruently when making decisions regarding player recruitment in soccer, yet there have been few attempts to examine the level of agreement between these methods. Therefore, we compare levels of agreement between subjective and objective assessments of physical qualities associated with youth soccer...
Article
Full-text available
Considering the vast physical and neural developments experienced throughout adolescence, the reliability of physical performance may vary in youth populations. This study aimed to examine the reliability of change of direction (COD) and agility tests in youth soccer players. Altogether, 86 youth soccer players, aged 13.6 ± 2.0 years, volunteered t...
Article
The aim of this study was to determine the influence of body weight or lean body mass-based load on Wingate Anaerobic Test performance in male and female endurance trained individuals. Thirty-one participants (22 male cyclists and triathletes and 9 female triathletes) completed two randomized Wingate Anaerobic Test (body weight and lean body mass l...
Article
Full-text available
This study aims to describe the intensity and load demands of different stage types within a cycling Grand Tour. Nine professional cyclists, whom are all part of the same World-Tour professional cycling team, participated in this investigation. Competition data were collected during the 2016 Giro d’Italia. Stages within the Grand Tour were classifi...
Article

Purpose: To describe the training intensity and load characteristics of professional cyclists using a 4-year retrospective analysis. Particularly, this study aimed to describe the differences in training characteristics between men and women professional cyclists. Method: For 4 consecutive years, training data were collected from 20 male and 10...
Article

This study aimed to establish between-day reliability and validity of commonly used field-based fitness tests in youth soccer players of varied age and playing standards, and to discriminate between players without (“unidentified”) or with (“identified”) a direct route to professional football through their existing club pathway. Three-hundred-and-...

Full-text available
Because of the intrusiveness of laboratory testing on the cyclist’s training or competition programme, evidence on field-based tests to track performance and establish training zones is valuable for coaches and practitioners. The aim of this study was to assess the relationship between an 8-min time trial (8MT) performed in the field and physiologi...
Conference Paper
Full-text available
Training load measures that demonstrate a strong dose-response relationship will provide coaches with a greater understanding of how players may respond to a given training session (Manzi et al., 2009). Therefore, the aim of this study is to identify the dose-response relationship between training load measures and changes in aerobic fitness in aca...
