Isocapnic hyperpnea training improves performance in competitive male runners
The effects of voluntary isocapnic hyperpnea (VIH) training (10 h over 4 weeks, 30 min/day) on ventilatory system and running performance were studied in 15 male competitive runners, 8 of whomExpand

Respiratory muscle training improves swimming endurance in divers
Respiratory muscles can fatigue during prolonged and maximal exercise, thus reducing performance. The respiratory system is challenged during underwater exercise due to increased hydrostatic pressureExpand

The physiology and pathophysiology of human breath-hold diving.
This is a brief overview of physiological reactions, limitations, and pathophysiological mechanisms associated with human breath-hold diving. Breath-hold duration and ability to withstand compressionExpand

Cardiovascular changes during deep breath-hold dives in a pressure chamber.
Electrocardiogram, cardiac output, and blood lactate accumulation were recorded in three elite breath-hold divers diving to 40-55 m in a pressure chamber in thermoneutral (35 degrees C) or cool (25Expand

Alveolar gas composition and exchange during deep breath-hold diving and dry breath holds in elite divers.
End tidal O2 and CO2 (PETCO2) pressures, expired volume, blood lactate concentration ([Lab]), and arterial blood O2 saturation [dry breath holds (BHs) only] were assessed in three elite breath-holdExpand

Effects of immersion and static lung loading on submerged exercise at depth.
The effects of static lung loading in the range +20 cmH2O to -20 cmH2O was investigated in 3 male subjects breathing air during submerged exercise in the prone position at pressures ranging from 1.45Expand

Respiratory function in the upright, working diver at 6.8 ATA (190 fsw).
The influence of static lung loading on a number of respiratory parameters was investigated in subjects performing graded leg exercise in an upright posture while submerged and breathing air atExpand

Cardiac performance in humans during breath holding.
The effects on cardiac performance of high and low intrathoracic pressures induced by breath holding at large and small lung volumes have been investigated. Cardiac index and systolic time intervalsExpand

Alveolar gas composition before and after maximal breath-holds in competitive divers.
The urge to breathe, as stimulated by hypercapnia, is generally considered to cause a breath-hold diver to end the breath-hold, and pre-breath hold hyperventilation has been suggested to causeExpand
