Effect of low-intensity leg exercise on ventilatory threshold during incremental arm exercise.
It is known that lactate, the level of which is increased during exercise, disappears more rapidly during low-intensity exercise than during passive recovery (Belcastro and Bonen, 1975; Stamford et al., 1981). This is because lactate can be used as an energy source during low-intensity exercise. If lactate can be used in such a way, it is supposed that the lactate that is produced during high-i...
متن کاملMechanical ventilatory constraints during incremental cycle exercise in human pregnancy: implications for respiratory sensation.
UNLABELLED The aim of this study was to identify the physiological mechanisms of exertional respiratory discomfort (breathlessness) in pregnancy by comparing ventilatory (breathing pattern, airway function, operating lung volumes, oesophageal pressure (P(oes))-derived indices of respiratory mechanics) and perceptual (breathlessness intensity) responses to incremental cycle exercise in 15 young,...
متن کاملAdvanced Mechanical Ventilatory Constraints During Incremental Exercise in Class III Obese Male Subjects.
BACKGROUND We investigated the role of mechanical ventilatory constraints in obese class III subjects during incremental exercise. METHODS We examined 14 control subjects (body mass index [BMI], 23.6 ± 3.2 kg/m(2)), 15 obese class II subjects (BMI, 37.2 ± 4.5 kg/m(2)), and 17 obese class III subjects (BMI, 53.4 ± 6.8 kg/m(2)). All subjects performed pulmonary function tests and maximal inspir...
متن کاملThe Relationship between the Isocapnic Buffering Phase and Ventilatory Threshold in Endurance Athletes and Team Sport Athletes during an Incremental Exercise Test
Background. There is sparse literature examining the ICB phase of aerobic- and anaerobic-trained athletes. Measurements of ICB phase values of athletes can help to evaluate the sport’s physiological demands and understand the physiological adaptations in response to physical training. Objectives. The purpose of this study was to examine the relationship between the isocapnic buffering (IC...
متن کاملThe aerobic capacity and ventilatory efficiency during exercise in Qigong and Tai Chi Chuan practitioners.
The objective of this study was to compare cardiorespiratory responses to exercise among older Qigong participants, Tai Chi Chuan (TCC) practitioners and normal sedentary controls during cycle ergometry. Thirty-six community-dwelling men with a mean age of 59.1 +/- 6.6 years participated in this study. Each group (Qigong, TCC and control) included 12 subjects with matched age and body size. The...
