N2 - To determine how increased ventilatory demand impacts ventilatory kinematics, we compared the total chest wall volume variations (V CW) of male and female endurance-trained athletes (ET) to untrained individuals (UT) during exercise. We hypothesized that training and gender would have an effect on V CW and kinematics at maximal exercise.Gender and training significantly influenced chest wall kinematics. Female ET did not change chest wall end-expiratory volume (V CW,ee) or pulmonary ribcage (V RCp,ee) with exercise, while female UT significantly decreased V CW,ee and V RCp,ee with exercise (p<0.05). Female ET significantly increased pulmonary ribcage end-inspiratory volume (V RCp,ei) with exercise (p<0.05), while female UT did not change V RCp,ei with exercise. Male ET significantly increased V RCp,ei with exercise (p<0.05); male UT did not. Men and women had significantly different variation of V CW (p<0.05). Women demonstrated the greatest variation of V CW in the pulmonary ribcage compartment (V RCp). Men had even volumes variation of the V RCp and the abdomen (V Ab).In conclusion, gender and training had a significant impact on ventilatory kinematics.
