The purpose of this investigation was to determine the oxygen consumption, heart rate and plasma lactate responses at the fatigue threshold (FT) and estimate the length of time the FT could be maintained. Ten adult males (mean age +/- SD = 21.1 +/- 1.3 yrs) volunteered to perform a maximal treadmill test and FT test. During the maximal test, VO2 heart rate(More)
The purpose of this study was to examine the relationship between anaerobic running capacity and peak plasma lactate. Twelve adult males (mean age +/- SD = 21.9 +/- 1.2 yrs) performed a critical velocity test from which anaerobic running capacity was determined and a maximal treadmill running test from which peak plasma lactate was determined from(More)
The salivary immunoglobulin A (s-IgA) and cortisol responses to maximal exercise were examined in 24 adult males (X +/- SD; 22.1 +/- 3.0 yrs) before and after 10 weeks of run training. The subjects performed an incremental treadmill test to exhaustion and were randomly assigned to one of three groups: control (CON; n = 5), low intensity training (LO; n =(More)
Life-event stress (LES) was used to classify elite athletes (n = 39) into high- and low-LES groups. A repeated measures analysis of variance revealed higher cortisol concentration after a graded exercise lest among the high-LES group relative to the low-LES group, which was maintained for up to 20 hr. Subsequent prospective analyses further indicated that(More)
The purpose of this study was to determine the validity of 23 anthropometric equations for estimating body composition and minimal wrestling weight in high school wrestlers. A total of 409 high school wrestlers (M age +/- SD = 16.42 +/- 1.03 yrs) volunteered for this study. Twenty-three anthropometric measures including eight skinfolds, nine circumferences,(More)
The purpose of this study was to examine salivary immunoglobulin A (s-IgA) responses to exhaustive exercise. Twenty-nine, college age (means +/- SD = 21.45 +/- 3.1 yrs; range 18-29 yrs) moderately active males (running < 10 miles per week) performed an incremental treadmill test to exhaustion. Unstimulated salivary samples, collected before as well as(More)
The purposes of this study were to evaluate the intertester error in anthropometry and its effect on estimations of actual body density (ABD), as well as to assess the validity of predicted body density (PBD) from selected anthropometric equation. Sixteen adult males X +/- SD = 21.98 +/- 1.65 years) volunteered to be measured by three experienced and(More)
Master's level social work gerontology students formed a Task Force on Missouri Medicaid as the primary course project of the Social Policy and Aging class at George Warren Brown School of Social Work, Washington University in St. Louis. Led by students, the Task Force collaborated with community leaders to address issues with the escalating enrollment and(More)
This study was designed to investigate the relationship between step time and step length in a healthy population of young adults. The sample was composed of 10 females and 10 males with ages ranging from 19 to 25 years. The subjects walked along a resistive grid walkway at an audio-controlled cadence of 80 steps per minute. These trials consisted of two(More)
