OBJECTIVE To examine cardiopulmonary performance in 52 adult patients with a Fontan circulation. DESIGN Retrospective cohort study. Values of maximum oxygen uptake (VO(2)max), maximum heart rate (HRmax), forced vital capacity (FVC), and forced expiratory volume in one second (FEV(1)) were compared with predictive values for different age groups. Patients were further subdivided into those wit...

The aim of this case study was to describe the physiological and regulatory processes, by means of heart rate (HR) monitoring and pacing strategy, in a top-level race walker (age: 32 years; height: 1.76 m; body mass: 62 kg; training volume: 130-150 km·wk) who was focused on the attainment of the 5-km indoor race walk (RW) World Record. The HRmean was 185 ± 14.9 b·min, with an HRmean/HRmax ratio...

The aim was to investigate the effects of concurrent exercise at moderate (MO) and light (LI) intensity on post-exercise hypotension (PEH). Ten women with borderline hypertension were submitted to the experimental procedure consisting of three sessions. In the MO session, the participants ran on the treadmill for 22 minutes at 65% of HRmax and then performed 5 resistance exercises against resis...

[Purpose] The present study aimed at examining changes in aerobic energy metabolism and performance in cycling athletes after 2 weeks of intermittent training in a multistep hypobaric hypoxia environment. [Subjects and Methods] We also aimed at using the findings to propose an efficient training program in hypobaric hypoxia for endurance athletes with disabilities. The study participants were t...

In the present study we examined the moderating effect of the power motive on salivary cortisol responses to acute psychosocial stress and exercise in adolescents. Fifty-seven high school students aged M = 14.8 years participated in the study. The Operant Motive Test was applied to measure the implicit power motive and the Personality Research Form was used to measure the explicit power motive....
