Cardiac effects of a competitive road race in trained child runners.
BACKGROUND Animal studies and investigations of adult endurance athletes indicate a transient depression of myocardial function after prolonged high-intensity exercise. PURPOSE To determine whether a similar decrease is observed in child distance runners after a 4-km competitive road race. METHODS Anthropometric measures, resting M-mode echocardiograms, maximal cycle exercise tests with est...
متن کاملFoot strike patterns of recreational and sub-elite runners in a long-distance road race.
Although the biomechanical properties of the various types of running foot strike (rearfoot, midfoot, and forefoot) have been studied extensively in the laboratory, only a few studies have attempted to quantify the frequency of running foot strike variants among runners in competitive road races. We classified the left and right foot strike patterns of 936 distance runners, most of whom would b...
متن کاملPrimary and secondary exercise dependence in a community-based sample of road race runners.
The purpose of our study was to examine exercise dependence (EXD) in a large community-based sample of runners. The secondary purpose of this study was to examine differences in EXD symptoms between primary and secondary EXD. Our sample included 2660 runners recruited from a local road race (M age = 38.78 years, SD = 10.80; 66.39% women; 91.62% Caucasian) who completed all study measures online...
متن کاملIntra-Subject Variability of 5 km Time Trial Performance Completed by Competitive Trained Runners
Time-trials represent an ecologically valid approach to assessment of endurance performance. Such information is useful in the application of testing protocols and estimation of sample sizes required for research/magnitude based inference methods. The present study aimed to investigate the intra-subject variability of 5 km time-trial running performance in trained runners. Six competitive train...
متن کاملCardiac Output and Performance during a Marathon Race in Middle-Aged Recreational Runners
PURPOSE Despite the increasing popularity of marathon running, there are no data on the responses of stroke volume (SV) and cardiac output (CO) to exercise in this context. We sought to establish whether marathon performance is associated with the ability to sustain high fractional use of maximal SV and CO (i.e, cardiac endurance) and/or CO, per meter (i.e., cardiac cost). METHODS We measured...
