The age of the best marathon performance has been well investigated for flat city marathon running, but not for mountain marathon running. The aim of this study was to determine the age of the best mountain marathon performance and to compare to results of a flat city marathon. Race times and ages of finishers of a mountain marathon with 1,830 m of altitude change (Jungfrau Marathon, Switzerlan...

The aim of this study was to examine the interaction between aging and 10 years of racing in endurance runners. Race-time data from 194 runners who had completed 10 consecutive 56-km ultramarathons were obtained. The runners were either 20.5 +/- 0.7, 30.0 +/- 1.0, 39.9 +/- 0.9, or 49.4 +/- 1.0 years old at their first race. Each runner's race speed was determined for each race over the 10 years...

OBJECTIVE The aim of the present work is to evaluate bulimic behaviors among female adolescent endurance runners. METHODS From a total of 40 athletes affiliated to the Track and Field Federation of Rio de Janeiro, 17 female teenager endurance runners (age: 16+/-1,8 years) were examined. The instrument used to investigate bulimic behavior and its gravity was BITE (Bulimic Investigatory of Edin...

Kenyan athletes have dominated international distance running in recent years. Explanations for their success include favourable physiological characteristics, which could include favourable genetic endowment, and advantageous environmental conditions. The aim of this study was to compare the demographic characteristics of elite Kenyan runners with those of the general Kenyan population. Questi...

ELITE SPRINTERS RUN 100-m races at 10 m/s, but the (different) elite runners who race over 10 km can manage only about 6 m/s over the longer distance. Elite cyclists reach 20 m/s in short sprints but only about 14 m/s over 10 km. It is well known that long races are slower than sprints because they have to be supported almost entirely by aerobic metabolism. Anaerobic metabolism makes higher pow...

BACKGROUND Although several studies have investigated gender differences in the substrate and endocrine responses during and following endurance exercise, few have studied sex differences during a more prolonged recovery period post endurance exercise. The purpose of this study was to compare and characterize the endocrine and substrate profiles of trained male and female adult runners during t...

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...

The present study analyzed the acute effects of an incremental running test on countermovement jump (CMJ) and handgrip strength performance in endurance athletes, considering the effect of post-exercise recovery time and sex. Thirty-three recreationally trained long-distance runners, 20 men and 13 women, participated voluntarily in this study. The participants performed the Léger test, moreover...
