Anaerobic characteristics of preadolescent asthmatic and nonasthmatic males were measured using the accumulated oxygen deficit (AOD) on 10 asthmatics (mean age = 10.9 years) and 10 nonasthmatics (mean age = 11.1 years). Subjects ran to exhaustion at speeds that were 110% and 130% of their V̇O2 peak. Mean AOD values for 110% and 130% were 53.23 ± 4.02 and 50.60 ± 2. 81 ml · kg−1, respectively, for the asthmatic children’s and 51.59 ± 2.66 and 47.04 ± 3.44 ml · kg−1, respectively, for the nonasthmatic children. There were no statistically significant differences in anaerobic characteristics measured by AOD values (p > .05) between intensities and groups. FEV1 data revealed that there was no bronchoconstriction occurring in either group under either of the test intensity conditions for up to 15 min postexercise.
