BACKGROUND AND PURPOSE Previous investigations have demonstrated that a regimen of high-intensity inspiratory muscle training (IMT) resulted in changes in ventilatory function and exercise capacity in patients with chronic lung disease, although the effect of high-intensity IMT in subjects who are healthy is yet to be determined. The purpose of this study,(More)
The purpose of this study was to determine if there were any differences in the submaximal energy cost of movement between overweight (OW) and non-overweight (NO) children while playing a dance simulation video game, Dance Dance Revolution (DDR) and to determine if the cardiorespiratory measures obtained while playing the game met the American College of(More)
Joseph Pilates (1880±1967) created a system of ®tness exercises that are still practiced in a more or less modi®ed form. Within the last two decades, there has been a signi®cant increase in the popularity of such Pilates-inspired (PI) exercises. This paper describes current claims for the e€ectiveness of PI exercises and comments on their validity. Motor(More)
PURPOSE The aim of this study was to evaluate the effectiveness of a strength and aerobic interval training program on arm-cranking economy, aerobic capacity, and gross motor function in children and adolescents with spastic diplegic cerebral palsy (CP). METHODS Seven subjects (five females, two males; mean age 15.9, range 14-18 yr) participated in a(More)
OBJECTIVE The objective of this study was to assess the influence of different relaxation modes: stretching (ST), active recovery (AR), and passive recovery (PR) on muscle relaxation after dynamic exercise of the quadriceps femoris. DESIGN Ten healthy male volunteers between 24 and 38 yrs of age participated in this study. After the warm-up, subjects(More)
The purpose of this study was to evaluate whether a 12-wk functional circuit-training program (FCT) could alter markers of physical frailty in a group of frail community-dwelling adults. Fifty-one individuals (31 women, 20 men), mean age (± SD) 84 (± 2.9) yr, met frailty criteria and were randomly assigned into groups (FCT = 26, control group [CG] = 25).(More)
From the scant data available, it seems that children with CP have a low maximum Vo2, a high O2 cost of submaximal exercise, and inefficient gait mechanics characterized by high levels of co-contraction. Despite the non-steady-state nature of habitual activity, there seem to be no published data focusing on Vo2 kinetics in children with CP Before measuring(More)
PURPOSE The extent that enhanced ventricular function contributes to superior aerobic fitness of trained athletes is unclear. This study compared cardiovascular responses to progressive cycle exercise in 12 adolescent soccer players and 10 untrained boys with assessment of ventricular inotropic and relaxation properties by Doppler ultrasound techniques.

Whilst endothelial dysfunction is associated with a sedentary lifestyle, enhanced endothelial function has been documented in the skin of trained individuals. The purpose of this study was to investigate whether highly trained adolescent males possess enhanced skin microvascular endothelial function compared to their untrained peers. Seventeen highly and(More)
PURPOSE To evaluate the effect of maturity status on the autonomic nervous system at rest and recovery after short-term, high-intensity exercise in adolescents. METHODS A biological maturity age was estimated in 27 males by calculating the years from peak height velocity (PHV) using a multiple regression equation. Subjects were divided into two groups:(More)
