English summary
The FVC and FEVt was measured in 459 indi-
viduals. Of these 340 were nonathletes, 174 females
and 166 males aged 7-35 years, and 119 male athle-
tes aged 11—35 years. No difference by sex was ob-
served up to tlie age 13 or 14 years, but thereafter
the males slioived aboud 20—30% higher values.
The athletes were not found to have higher values
than the nonathletic males. At tlie age 15—16 years
there was greater increase in FVC per cm body
height for males than for females. Height showed
the highest correlation with FVC and FEVi much
higher than previously reported. Prediction for-
mulae are given and a comparison shows that pre-
viously reported formulae give lower values than the
ones reported in tlie present study.
