Purpose: Metabolic perturbation and VO[subscript 2] on-kinetics are potential modifiers of fatigue and vary in importance depending on the exercise task. Thus, performance fatigability during high-intensity exercise seems to be exercise mode dependent, affecting tolerance in the severe domain. However, the effects of exercise mode on severe domain…

Background: Persons with Down syndrome (DS) have low aerobic exercise capacity. The present authors sought to compare the oxygen uptake efficiency slope (OUES) between adults with and without DS performing graded exercise testing (GXT) and to investigate its relationship with peak oxygen uptake (VO[subscript 2peak]) in both groups of participants.…

Purpose: The purpose of this study was to evaluate the use of a treadmill walk-jog-run exercise test previously validated in adults and physical activity questionnaire data to estimate maximum oxygen consumption (VO[subscript 2]max) in boys (n = 62) and girls (n = 66) aged 12 to 17 years old. Methods: Data were collected from Physical Activity…

Purpose: This study investigated whether metabolic respiratory requirements (treadmill workload) affected glottal valving in phonation, based on aerodynamic measures, when a sound pressure level (vocal SPL) is dictated as a target goal. Consistent with a theory of action, we hypothesized that adjustments in glottal valving as measured by laryngeal…

Background: Individuals with intellectual disability (ID) have very low physical activity and low peak oxygen uptake (VO[subscript 2peak]), potentially explained by physiologically lower peak heart rates (HR[subscript peak]). Method: The present authors performed a retrospective analysis of a large data set of individuals with intellectual…

Purpose: There is currently no standardized testing protocol for assessing clients' fitness/health within the Australian fitness industry. This study examined the perceptions of the feasibility of using a standardized testing protocol among Australian fitness industry professionals. Method: In 2014, 1,206 registered fitness industry professionals…

Walking is a common activity of daily life and researchers have used the range 3-6 km.h[superscript -1] as reference for walking speeds habitually used for transportation. The term self-selected (i.e., individual or comfortable walking pace or speed) is commonly used in the literature and is identified as the most efficient walking speed, with…

The study was designed to determine the effect of upright-posture (UP) versus semirecumbent (SR) cycling on commonly used measures of maximal and submaximal exercise capacity. Nine healthy, untrained men (M age = 27 years, SD = 4.8 years) underwent steady-state submaximal aerobic testing followed by a ramped test to determine maximal oxygen…

When attempts are made to utilize the procedures generally accepted in evaluation to look at something as vague as the term "exercise", confusion becomes compounded exponentially. It is important that the fundamental elements of movement, the laws of motion, and the basic movement of skills be taught to everyone. If there is a need to know what…

The Health Promotion Program began with establishment of a one-credit course in health promotion and wellness and the training of family practice residents at the Mountain Area Health Education Center to serve as lab leaders in the course. The course later became part of the university's general education requirements. In addition, a health…

The implications of the use of the Health-Related Physical Fitness Test are outlined in terms of six physical fitness objectives leading to achieving fitness and motivating students to good exercise habits. Specific suggestions regarding the use of the test in the physical education program are offered. (JMF)

The purpose of this study was to develop a regression equation to predict maximal oxygen uptake (VO[subscript 2]max) based on nonexercise (N-EX) data. All participants (N = 100), ages 18-65 years, successfully completed a maximal graded exercise test (GXT) to assess VO[subscript 2]max (M = 39.96 mL[middle dot]kg[superscript -1][middle…
