Hemoglobin/myoglobin oxygen desaturation during Alpine skiing.

Purpose: To investigate muscle blood volume (BV) change and hemoglobin/myoglobin oxygen desaturation (OD) during simulated giant slalom (GS) and slalom (SL) Alpine ski racing.

Methods: Joint angle, BV, OD, and heart rate (HR) were evaluated during GS and SL events in 30 junior elite skiers ages 9--17 yr (13.5 +/- 2.

Self-reported symptoms and exercise-induced asthma in the elite athlete.

Purpose: The purpose of this study was to compare self-reported symptoms for exercise-induced asthma (EIA) to postexercise challenge pulmonary function test results in elite athletes.

Methods: Elite athletes (N = 158; 83 men and 75 women; age: 22 +/- 4.4 yr) performed pre- and post-exercise spirometry and were grouped according to postexercise pulmonary function decrements (PFT-positive, PFT-borderline, and PFT-normal for EIA).

Incidence of exercise-induced bronchospasm in Olympic winter sport athletes.

Purpose: The purpose of this project was to determine the incidence of exercise-induced bronchospasm (EIB) among U.S. Olympic winter sport athletes.

Exercise-induced asthma screening of elite athletes: field versus laboratory exercise challenge.

Purpose: The purpose of this study was to compare a laboratory based exercise challenge (LBC) to a field based exercise challenge (FBC) for pulmonary function test (PFT) exercise-induced asthma (EIA) screening of elite athletes.

Methods: Twenty-three elite cold weather athletes (14 men, 9 women) PFT positive for EIA (FBC screened) served as subjects. Twenty-three gender and sport matched controls (nonasthmatics) were randomly selected to establish PFT reference values for normal elite athletes.

Exercise tolerance, body composition and blood lipids in obese African-American women following short-term training.

Background: The purpose of this investigation was to examine the exercise tolerance, body composition and blood lipids in African-American women, possessing greater than or equal to 30% body fat, following six weeks of endurance training.

Methods: Oxygen consumption (VO2), central hemodynamics, blood lipids, body weight, body fat, and the body mass index of seven subjects (21.0 +/- 0.
