“…This agrees with the results of others (Girandola et ah, 1977;Maron et al, 1979;Buono et al, 1981). The RV remained significantly increased over the pre-exercise value through 30 min of recovery.…”

“…The RV remained significantly increased over the pre-exercise value through 30 min of recovery. Similar results have previously been reported (Buono et al, 1981). We also found a significant mean increase of 130 ml (1.9%) in the 5 min post-exercise TLC.…”

“…Previous studies have shown that residual volume (RV) increases during exercise (Hanson et al, 1962;Stubbing et al, 1980) and remains elevated over the pre-exercise value through 30 min of recovery (Buono et al, 1981). Although this effect of exercise on RV is well documented, the physiological mechanisms responsible for the increase are still unclear.…”

“…Although this effect of exercise on RV is well documented, the physiological mechanisms responsible for the increase are still unclear. Recently, several investigators suggested that a subclinical pulmonary oedema may be responsible for the increase in RV following exercise (Buono et al, 1981;Maron et al, 1979). They suggest that during the early stages of pulmonary oedema, periairway cuffing of fluid may result in small airway narrowing, thus allowing the airways to close sooner during an expiration.…”

A series of three studies was conducted to help determine the physiological mechanism responsible for the previously reported increase in residual volume following maximal exercise. Study I showed that in 18 male volunteers, residual volume and total lung capacity were significantly (P<0.05) increased over the pre-exercise values through 30 and 15 min of recovery, respectively. Transthoracic electrical impedance was significantly decreased below the pre-exercise value through 15 min of recovery. This suggests that there was an increase in intrathoracic fluid following exercise. By experimentally manipulating central blood volume via G-suit inflation and venous occlusion, study II (n = 10) showed that post-exercise residual volume was relatively insensitive to increases in intravascular fluid within the thorax. Study III (n = 5) showed that the post-exercise diffusion capacity (D Lco /V A was unchanged following exercise, despite an increase in the post-exercise heart rate. It was concluded that a subclinical pulmonary oedema is present following maximal exercise. A logical sequence of events was proposed as a possible explanation for the response of residual volume following exercise.

“…While there is evidence that exercise causes an increase in lymph flow from the limbs (7) and heart (8), there are no published data on the effect of exercise on lung lymph flow. There is, however, indirect evidence in animals (9) and man that exercise with (10, 1 1) or without (12)(13)(14)(15)(16) hypobaric hypoxia causes an increase in extravascular lung water. There are also reports of acute pulmonary edema occurring in man during very vigorous exercise at sea level (17) and during moderate exercise at high altitude (18)(19)(20).…”

As bstract. Vigorous exercise causes a marked increase in cardiac output with only a minimal increase in measureable pulmonary vascular pressures. These changes in pulmonary hemodynamics should affect lung water and solute movement.On nine occasions, we measured the effect of normoxic exercise on lung lymph flow in four sheep and two goats with chronic lymph fistulas (wt = 15-25 kg). In addition, lymph flow was also measured on five occasions in sheep during exercise at reduced barometric pressures (430 and 380 mmHg). During normobaria, the animals ran at 3-5 km/h with 0-10% elevation of the treadmill for 15 to 85 min. Exercise on average caused a 100% increase in cardiac output, a 140% increase in lung lymph flow, and a slight but significant reduction in lymph to plasma concentration ratio (l/p) for total protein and albumin (mol wt = 70,000). There was a significant linear correlation between lymph flow and cardiac output (r = 0.87, P < 0.01). There was no change in l/p for IgG (mol wt = 150,000) or IgM (mol wt = 900,000) and no significant change in mean pulmonary arterial (Ppa) or mean left atrial (Pla) pressures. Transition from normobaria to hypobaria caused an increase in Ppa but no change in Pla, cardiac output, or lymph flow. Exercise during hypobaria caused increases in lymph flow that were qualitatively similar to changes observed during normobaric exercise:These investigations were presented in part at

We measured pulmonary function in 12 healthy volunteers before and at 5-min intervals for 30 min following treadmill exercise of 30 min duration performed under control (20 degrees C) and cold (-11 degrees C) ambient temperatures. Post-run changes in forced vital capacity (FVC), residual volume (RV) and peak expiratory flow rate were similar between the two temperature conditions. FVC decreased slightly but significantly 5 min post-run (-0.25 +/- 0.20 l and -0.21 +/- 0.20 l, for control and cold conditions respectively) and returned to baseline by 30 min. RV increased significantly post-exercise (+0.07 +/- 0.09 l and +0.14 +/- 0.1 l, control and cold respectively) and remained elevated for 30 min. Forced expired volume in 1 s was not significantly different following either run. Post-exercise, maximum mid-expiratory flow rate and flows at 50% and 25% of vital capacity were not significantly different between warm and cold conditions. These data suggest that changes in lung volumes following exercise under cold ambient conditions are similar to changes seen following warm exercise of similar duration. In non-asthmatics, moderate exertion under cold ambient conditions does not appear to cause clinically significant decreases in expiratory flow rates as compared to similar exertion under warm conditions.
