Influence of the settings of the cycling ergometer in all out sprints on power output and calculated glycolytic rate

Collaborating organisations: Zuyd University of Applied Sciences, Maastricht, Netherlands KU Leuven, Leuven, Belgium, Reinout van Schuylenbergh, PhD University Hildesheim, Hildesheim Germany, Faculty Sport Science Prof. Dr. Sebastian Gehlert, Ergometer settings impact on power profile during 20s isokinetic sprint on Cyclus II ergometer. Cyclus II ergometer Short description: Weber (2003) described a specific test protocol for cycling to assess the maximal glycolytic rate (Vlamax). This protocol was specifically designed for an SRM ergometer and consisted of a 15s isokinetic seated sprint (120 rpm). The ergometer settings were adjusted based on body mass. Until now, it remains unclear to what extend the ergometer settings of a cyclus II ergometer (one of the most used high-end ergometers in research and athlete monitoring) impact…

Substrate Utilisation During Interval and Stochastic Load Patterns

Short description: From cycling races to football matches: sparing carbohydrates and utilising fat as a fuel is of pinnacle importance in many sports competitions. Especially in competitions with non steady load patterns (cycling, basketball, soccer, olympic triathlon, XC skiing) the race decisive moments depend highly on anaerobic energy supply and therefore on the availability of glucose as a fuel. In contrast the assessment of substrate utilisation using coventional testing methods such as a metabolic cart is limited to quasi steady state and submaximum load patterns. Hence the typical laboratory assessment of fat and carbohydrate utilisation cannot be applied to analyse substrate utilisation in may sporting events. Long description: Experiments Fifteen healthy trained males were recruited for this project. Each of…

Development & Validation of a Model of Cardiopulmonary VS. Muscular Oxygen Uptake Kinetics

Collaborating organisations: Advisor: Prof. Dr. Aaron Baggish, Institute of Sport Sciences, University de Lausanne, Switzerland Research collaboration: Dr. Philippe Hellard, Creps Aquitaine, Bordeaux France Short description: Oxygen Kinetics at the on and offset of exercise has had researchers puzzling for decades. In practical application such as in vivo tests using a metabolic cart or VO2 analyzer, only whole body pulmonary oxygen uptake (pVO2) is accessible. Pulmonary VO2 is influence not only by muscle VO2 but also by cardiac output, blood volume, oxygenation amongst other factors. The aim of this project is to build and validate a model that discloses those factors influencing pVO2 in a quantitaive way, hence open a clearer view on pVO2 data. Long description: Experiments Twelve healthy…

Can a world class junior cyclist beat a multiple Tour de France winner?

  • Sport Performance & Science Reports
  • Dr Reinout Van Schuylenbergh

Three-week cycling Grand Tours (Giro d’Italia, Vuelta a Espagna, Tour de France) are one of the most physically demanding and iconic events in sports competition. Stages within the Grand Tours are classified into individual time trials, flat, semi-mountainous and mountain stages. The general classification in Grand Tours is typically won during the mountain stages and individual time trials. High maximal oxygen consumption rates (VO2max) have repeatedly been observed in Grand Tour winners (1,2). It is suggested that a…

INSCYD physiological performance software is valid to determine the maximal lactate steady state in male and female cyclists

  • Exercise Physiology Research Group, Department of Movement Sciences, KU Leuven, Leuven, Belgium
  • Chiel Poffé, Kaat Van Dael, Reinout Van Schuylenbergh

The maximal lactate steady state (MLSS) is defined as the highest workload that can be maintained without blood lactate accumulation over time. The power output at MLSS (PMLSS) is regularly implemented to define training zones, quantify training progress, or predict race performance. The gold standard methodology for MLSS determination requires two to five trials of…

Calculated glycolytic power and substrate utilization during a world record marathon in a female runner

  • Sport Performance & Science Reports
  • Robberechts R, Poffe C, Van Schuylenbergh R

Scientific research on marathon performance has focused on aerobic metabolism. However, anaerobic metabolism cannot be neglected as for a given ̇V O2max, the lower the gly- colytic power (VLamax) the higher the metabolic steady-state performance (1–4) and the lower the carbohydrate combustion rate at a given speed (5). In contrast, elite marathon runners use sudden pace changes as a tactical weapon (6). Obviously, such efforts require additional anaerobic energy. Therefore, an optimal range for VLamax in marathon running is…

Simulated metabolic responses during high-intensity interval training based on a mathematical model in elite swimmers

  • In book: The science of swimming and aquatic activities (pp.203-226) Publisher: Nova Science
  • Philippe Hellard, Ferran A. Rodríguez, Carl Dupont, David B Pyne, Alois Mader, Sebastian Weber

High-intensity interval training (HIT) has been described as a training method that strongly stimulates the mechanisms of metabolic, neuromuscular and technical adaptations. Studies focusing on the effects of HIT in swimmers are rare despite its widespread use in practice. It is thought that HIT can powerfully stimulate the three energy systems, both in metabolic and technical terms, to a level close to competitive performance. In high-level swimmers, it…

Discovering the sluggishness of triathlon running – using the attractor method to quantify the impact of the bike-run transition

  • Frontiers in Sports and Active Living
  • Christian Weich, Valentin Barth, Nikolai Killer, Veronica Vleck, Julian Erich, Tobias Treiber

Running in a triathlon, a so-called brick run, is uniquely influenced by accumulated load from its preceding disciplines. Crucially, however, and irrespective of race type, the demands of a triathlon always exceed the sum of its parts. Triathletes of all levels commonly report subjectively perceived incoordination within the initial stages of the cycle run transition (T2). Although minimizing it, and its influence on running kinematics, can positively impact…

Utility of INSCYD athletic performance software to determine Maximal Lactate Steady State and Maximal Oxygen Uptake in cyclists

  • Journal Of Science & Cycling
  • Tim Podlogar, Simon Cirnski, Špela Bokal, and Tina Kogoj

Serious amateur and elite athletes regularly take part in structured physiological testing sessions so that their progress gets tracked and training loads in the training plan correctly prescribed. Commonly, athletes are tested for the maximal oxygen uptake (V̇O2max) and maximal lactate steady state intensity (MLSS). While for the former expensive laboratory equipment is required, the latter requires multiple exercise trials for accurate determination. INSCYD athletic performance software is…

Load intensity determination in long-distance triathlon with INSCYD athletic performance software

  • Sport Performance & Science Reports
  • Carmen Ohr, Dr. Ralf Lindschulten

This study evaluates the utility of anaerobic threshold (AT) and maximum carbohydrate (CHO) intake (CarbMax) for predicting intensity in long-distance triathlons. Using INSCYD diagnostic tests on 22 participants, the findings indicate that CarbMax and race performance CHO combustion (CHORP) are better estimators for optimal racing intensity than AT. Average CHO combustion was 85.73 g·h^−1 for cycling and 87.71 g·h^−1 for running, slightly below the recommended 90 g·h^−1, suggesting …
