Observational study of potential risk factors of immersion pulmonary edema in healthy divers: exercise intensity is the main contributor.

Background: The risk factors of pulmonary edema induced by diving in healthy subjects are not well known. The aim of the present study was to assess the parameters contributing to the increase in extravascular lung water after diving.

Methods: This study was carried out in a professional diving institute.

Cardiorespiratory alterations induced by low-intensity exercise performed in water or on land.

The aim of this study was to compare the cardiorespiratory alterations induced by a low-intensity exercise performed on land or in water. Sixteen healthy subjects were investigated. The exercise consisted of a 1-h period of ergocycling at 35%-40% of peak oxygen uptake.

Severely obese adolescent girls rely earlier on carbohydrates during walking than normal-weight matched girls.

The purpose of this study was to determine the substrate oxidation rate and the exercise intensity at which maximal lipid oxidation and ventilatory threshold (VT) occur in obese (BMI: 36.6 ± 6.3 kg · m(-2)) and normal-weight adolescent girls (BMI: 18.

Inter-limb changes in arterial function after intense cycling exercise.

We investigated whether muscle exercise, by inducing a subsequent local response, alters local and systemic arterial function differently. Eleven healthy volunteers (31±8 years) performed a 45-min cycling session at a heart rate corresponding to 10% above ventilatory threshold. Measurements were performed before and 45 min after exercise.
