Effect of exercise on pulmonary functions (VC, EFV1, MVV and PEFR) was studied in 40 (M 29, F 11) elderly subjects (60-81 yrs) and in 60 (M 31, F 29) younger age group (12-55 yrs). However, there was no significant change in any parameter except MVV (61.24 ± 21.23 lit before and 74.86 ± 23.18 lit after exercise) in younger females. Older females could not do exercise for 8 minutes
