BACKGROUND: Near-infrared spectroscopy (NIRS) measurements of oxygenation reflect O2 delivery and utilization in exercising muscle and may improve detection of a critical exercise threshold. PURPOSE: First, to detect an oxygenation breakpoint (Δ[O2HbMb-HHbMb]-BP) and compare this breakpoint to ventilatory …

Background: The purpose of this study is to increase our understanding of environmental correlates that are associated with route choice during active transportation to school (ATS) by comparing characteristics of actual walking and cycling routes between home and school with the shortest possible route …

Cycling Lab is een uniek en dynamisch samenwerkingsverband tussen onderzoek, onderwijs, markt en eindgebruikers rondom fietsen. De kennis van al deze partijen wordt gebundeld om samen als Cycling Innovators een substantiële bijdrage televeren aan de profilering van Groningen en Drenthe als onderscheidende …

Purpose: The aim of this study was to evaluate the effect of kinematic chain manipulative therapy on the frontal plane knee movement in cycling. Methods: in this study 13 amateur cyclists aged between 25 and 65 years old participated and underwent kinematic chain manipulative therapy executed by a professional …

The Netherlands is known globally for its widespread use of bicycles and some call it a “cycling nation”. Indeed, many Dutch inhabitants own a bike and cycle frequently. Numbers show that 84% of the Dutch inhabitants from age 4 years and older own a bike. Those owners have an average of 1.3 bikes per …

This study analyses the determinants of cycling expenditure by means of a Tobit regression analysis, based on a dataset of 5,157 cyclists. Using a heterodox economic framework, 23 different variables are combined into two commonly used variable groups (socio-demographics, sports intensity variables) …

The purpose was to investigate perceived stress and recovery related to cycling performance of female athletes over one full year. 20 female athletes (age, 27±8 years; E2max, 50.3±4.6 mL·kg-1·min-1) were measured 8 times in one year to determine perceived stress and recovery (RESTQ-Sport) in relation …

Objective. There are no Dutch language disease-specific questionnaires for patients with patellofemoral pain syndrome available that could help Dutch physiotherapists to assess and monitor these symptoms and functional limitations. The aim of this study was to translate the original disease-specific …

When considering a composite strip or plate under certain thermal and environmental conditions and loadings, there is a minimum strain threshold for the appearance of the first micro crack. The associated strain level is defined here as “critical strain”. There are various active displacement methods …

While Amazonian forests are extraordinarily diverse, the abundance of trees is skewed strongly towards relatively few ‘hyperdominant’species. In addition to their diversity, Amazonian trees are a key component of the global carbon cycle, assimilating and storing morecarbon than any other ecosystem on …
