Purpose: The aim of this investigation was to compare gender differences in physiologic and perceptual responses during a 1-h run at recent marathon pace and running economy at three speeds in recreational marathon runners. Methods: In a counterbalanced design, 10 men and 10 women completed a 1-h treadmill run and a running economy test. Treadmill speed for the 1-h run ranged from 141 to 241 m·min−1 and 134, 168, and 188 m·min−1 for running economy. Physiologic parameters (oxygen uptake, carbon dioxide production, pulmonary ventilation, and heart rate) and perceived exertion were measured. Repeated-measures ANOVA was used to compare any gender differences (P < .05) during the 1-h run and a two-way ANOVA was used to compare running economy. With this sample, estimated marathon energy expenditure, body composition, and maximal physiologic function was reported.1 Results: With the exception of an allometric expression of VO2 (mL·min−1·kg BW−0.75), similar gender physiologic and perceptual responses were foun...

American women have made great advances in the sport of marathon running over the past 4 decades. The purpose of this study was to examine the trend of marathon times among American female runners between 1976 and 2005, and to compare physiological characteristics of male and female runners. The best marathon times of American female and male marathon runners for each year (1976–2005) were collected from several published sources. Two research studies were reviewed that examined a variety of phy...

Running performance depends on maximal oxygen uptake (VO 2 max), the ability to sustain a high percentage of VO 2 max for an extended period of time and running economy. Running economy has been studied relatively less than the other factors. Running economy, measured as steady state oxygen uptake (VO 2 ) at intensities below the ventilatory threshold is the standard method. Extrapolation to a common running speed (268 m/min) or as the VO 2 required to run a kilometer is the standard method of a...

The study tested the hypothesis that physiological measurements can predict marathon running performance in a top-level homogeneous group of males and females. Ten male, performance: 2:12:04, coefficient of variation (CV) = 2.33%, and 8 female marathon runners, performance: 2 :34:53, CV = 4.54%, performed an increment test on the treadmill (starting speed, 8 km·h -1 ; increments, 2km·h -1 ; increment duration, 3min to exhaustion). The heart rate (HR), VO 2 and the lactate concentrations were mea...

It has been suggested that gender differences in running should disappear as distances increase, particularly past the marathon. This suggestion is primarily based on differences in fuel utilization, muscle damage following exercise, relative improvements in performance over the past decades, and on the analysis of marathon vs. ultramarathon performances of men and women. We reasoned that the best comparison of the potential of a human is by the use of world best times, which should be reasonabl...

Objective: The conventional ratio method (milliliters O2 per mass) typically is used to express Vo2 peak. The goal of the current study was to compare Vo2 peak of obese girls with normal-weight girls by ratio and allometric scaling methods. Research Methods and Procedures: We compared Vo2 peak by ratio and allometric methods in 46 obese and 47 normal-weight girls. Indirect calorimetry was used to measure Vo2 peak during either treadmill running or walking. Regression analysis was used to determi...

The aim of this study was to verify the effect of endurance training on the pacing strategy and analyse the risk of premature fatigue during the 10-km performance in moderately trained runners. Study participants were 14 runners (18–35 years) who had training prescribed with peak velocity (Vpeak) and its time limit (tlim). Three tests were performed on a treadmill: two maximum incrementals for VO2max and Vpeak and one for tlim. The 10-km running performance was evaluated on a 400-m track. The me...

The aim of this review was to highlight research that has focused on examining expressions of peak oxygen uptake (VO2peak) in children and youth, with special reference to allometric scaling. VO2peak is considered the highest VO2 during an increasing workload treadmill or bicycle ergometer test until volitional termination. We have reviewed scholarly works identified from PubMed, One Search, EBSCOhost and Google Scholar that examined VO2peak in absolute units (L·min−1), relative units [body mass...

this viewpoint argues that the current world record (WR) in the marathon for women is at least equivalent to a sub-2-h marathon for men. The person who may eventually break the 2-h barrier in the marathon ([19][1]) will be male. Because the fastest men consistently outperform the fastest women in

Purpose Rating of perceived exertion (RPE) is a scale of exercise difficulty and has been hypothesized to be a regulator of work rate during self-pacing. The goal of this work was to develop a dynamic prediction of RPE and to characterize the control strategy employed to reduce work rate during self-paced exercise using RPE as feedback.

Objective: To assess gender differences in heart rate (HR) and perceptual responses during leg versus arm ergometry among healthy college-aged Saudis. Methods: Forty healthy college-age Saudis (20 males) performed, in a random cross-over design, two maximal graded exercise leg (LE) and arm ergometry (AE). HR was continuously monitored/recorded during resting and throughout exercise period. Participants rated their perceived exertion (RPE), using Borg scale, at the end of each two-minute stage. L...

Recent research suggests that women tend to exhibit less of a precipitous decline in run velocity during the latter stages of a marathon than men when the covariates of age and run time are controlled for. The purpose of this study was to examine this sex effect with the added covariate of heat stress on pacing, defined as the mean velocity of the last 12.2 km divided by the mean velocity of the first 30 km. A secondary purpose of this investigation was to compare the pacing profiles of the elit...
