Determination of Effect of Oral Vitamin D to Improve Ventilatory Threshold in Healthy Young Adults with Vitamin D Deficiency [PDF]
Background: Many studies have shown a high prevalence of vitamin D deficiency in different communities. Due to multiple roles of vitamin D in the body, this study was aimed to determine the effect of oral vitamin D3 on ventilatory threshold-1 in a ...

Beyond the second ventilatory threshold: The prevalence and reliability of a second respiratory compensation point and third ventilatory threshold. [PDF]
Respiratory data obtained from cardiopulmonary exercise testing is commonly used to study ventilatory thresholds (VT). Traditionally, these thresholds correspond to two physiological transition points where the cardiorespiratory and metabolic systems ...

Does ‘sub-threshold’ ventilatory stress promote healing after lung injury?
Excessive tidal stretching may initiate damage or retard healing after lung injury. However, it is seldom considered whether intracycle power and ventilatory forces of lesser magnitude than those required to cross an injury threshold might stimulate or ...

Validity and Reliability of Ventilatory and Blood Lactate Thresholds in Well-Trained Cyclists. [PDF]
PURPOSE:The purpose of this study was to determine, i) the reliability of blood lactate and ventilatory-based thresholds, ii) the lactate threshold that corresponds with each ventilatory threshold (VT1 and VT2) and with maximal lactate steady state test (
