The purposes of this study were to: 1) determine if the normative constant (K: range
35–47; clinical estimation of 40) to estimate maximal voluntary ventilation (MVV=K
forced expiratory volume [FEV1] ) for nondisabled individuals is similar to that of athletes
with physical disabilities; 2) compare measured MVV (MVVmeas) to the MVV predicted
using the measured mean K and a clinical K of 40 (MVV40); and 3) compare measured
breathing reserve (BRmeas; BR = [MVVmeas – VEmax] MVVmeas–1) to the BR using MVV predicted
from measured mean K and MVV40. Fifty-seven paralympic athletes (40 males, 17
females; 14 with spinal cord injury, 22 with poliomyelitis, 19 with cerebral palsy, and two
with bilateral amputations) participated in this study. The mean measured K for the athletes
was 45.0±8.8 (mean range per disability group, 42–50). There were no significant differences
between MVVmeas (162.2±38 • min–1) and BRmeas (36%±18%) and MVV and
BR predicted from mean measured K of 45 (MVV45=164.2±35.6 1 • min–1; BR45 =
38±14%). However, there were significant differences (p<0.001) between MVV and BR predicted
from K of 40 (MVV40 = 146.0±31.6 1 • min) and (BR40 = 30%±15%) when compared
to both MVVmeas, BRmeas, and MVV45, BR45, respectively. The results indicate that for
these paralympic athletes, 1) the K45 used to estimate MVV was in the high range when
compared to non-disabled individuals; 2) there was no significant difference between MVVmeas
and MVV45, or BRmeas and BR45; and 3) MVV40 and BR40 significantly underestimated
MVVmeas and BRmeas, respectively. |
