“…A year of intensive (12 h/week) swim training, for example, induced an increase in lung volumes (VC, TLC, and FRC) and expiratory flows (FEV 1 , MEF 50% , and MEF 25% ) in prepubescent girls compared with children who had a normal level of physical activity (109). Similarly, 8 weeks of twice-weekly high-intensity intermittent running training enhanced lung volume (FVC) and expiratory flows (FEV 1 , PEF, MEF 75% , and MEF 50% ) in prepubescent children compared with children who maintained their habitual physical activity (394).…”

During dynamic exercise, the healthy pulmonary system faces several major challenges, including decreases in mixed venous oxygen content and increases in mixed venous carbon dioxide. As such, the ventilatory demand is increased, while the rising cardiac output means that blood will have considerably less time in the pulmonary capillaries to accomplish gas exchange. Blood gas homeostasis must be accomplished by precise regulation of alveolar ventilation via medullary neural networks and sensory reflex mechanisms. It is equally important that cardiovascular and pulmonary system responses to exercise be precisely matched to the increase in metabolic requirements, and that the substantial gas transport needs of both respiratory and locomotor muscles be considered. Our article addresses each of these topics with emphasis on the healthy, young adult exercising in normoxia. We review recent evidence concerning how exercise hyperpnea influences sympathetic vasoconstrictor outflow and the effect this might have on the ability to perform muscular work. We also review sex-based differences in lung mechanics.

“…Potentially, HIT may be a useful alternative training approach. Children reach higher ventilations during high intensity exercise than adults, partially because they are more susceptible to developmental changes such as increased lung volumes, than adults depending upon the stage of maturation (Nourry et al, 2005). It is possible the adaptations could be even greater with children.…”

High-intensity interval training (HIT) has been utilized as a time-efficient strategy to induce numerous physiological adaptations and improve performance usually associated with "traditional" endurance training (ET). It is not known however, if HIT might lead to improvements in pulmonary function. Therefore we hypothesized that HIT would increase respiratory muscle strength and expiratory flow rates. Fifteen healthy subjects were randomly assigned to an ET group (n = 7) and a HIT group (n = 8).All subjects performed an incremental test to exhaustion (VO 2 max) on a cycle ergometer prior to and after training. Standard pulmonary function tests, maximum inspiratory pressure (PImax), maximum expiratory pressure (PEmax), and maximal flow volume loops, were performed pre training and after each week of training. HIT subjects performed a four week training program on a cycle ergometer at 90% of their VO 2 max final workload while the ET subjects performed exercise at 60-70% of their VO 2 max final workload. All subjects trained three days/ week. The HIT group performed five one-minute bouts with three minute recovery periods and the ET group cycled for 45 minutes continuously at a constant workload. A five-mile time trial was performed prior to training, after two weeks of training, and after four weeks of training. Both groups showed similar (p<0.05) increases in VO 2 max (~8-10%) and improvements in time trials following training (HIT 6.5 ± 1.3%, ET 4.4 ± 1.8%) with no difference (p>0.05) between groups. Both groups increased (p<0.05) PImax post training (ET ~25%, HIT ~43%) with values significantly higher for HIT than ET. There was no change (p>0.05) in expiratory flow rates with training in either group. These data suggest that whole body exercise training is effective in increasing inspiratory muscle strength with HIT leading to greater improvements than ET. Also, HIT offers a time-efficient alternative to ET in improving aerobic capacity and performance.iv

“…7 Nourrey C et al showed in a prospective study that aerobic exercise improves pulmonary function and alters exercise breathing pattern in children. 8 Fitch KD et al studied the effect of five months swimming training on school children with asthma and found improved lung function, and improved posture and fitness. 13 Kaufman C et al studied the effect of aerobic training on ventilatory efficiency in overweight children, and found that the training helped to reverse the decrements in cardiopulmonary function observed over a period of time in overweight children.…”

“…5 Most studies on the effects of physical activity are cross sectional ones, on special populations such as athletes or patients with COPD. [6][7][8] Physical activity rehabilitation is widely used in patients with pulmonary diseases. Exploration of the relation between aerobic exercise and respiratory functions, will aid in understanding the mechanisms of how aerobics improve patient's quality of life and in finding a better way to evaluate the effects of rehabilitation.…”
