  We provide an extended lattice study of the SU(2) gauge theory coupled to one
Dirac fermion flavour ($N_{\mathrm{f}} =1$) transforming in the adjoint
representation as the continuum limit is approached. This investigation is
supplemented by numerical results obtained for the SU(2) gauge theory with two
Dirac fermion flavours ($N_{\mathrm{f}} =2$) transforming in the adjoint
representation, for which we perform numerical investigations at a single
lattice spacing value, which is analysed together with earlier calculations.
The purpose of our study is to advance the characterisation of the infrared
properties of both theories, which previous investigations have concluded to be
in the conformal window. For both, we determine the mass spectrum and the
anomalous dimension of the fermion condensate using finite-size hyperscaling of
the spectrum, mode number analysis of the Dirac operator (for which we improve
on our previous proposal) and the ratio of masses of the lightest spin-2
particle over the lightest scalar. All methods provide a consistent picture,
with the anomalous dimension of the condensate $\gamma_*$ decreasing
significantly as one approaches the continuum limit for the $N_{\mathrm{f}} =
1$ theory towards a value consistent with $\gamma_* = 0.174(6)$, while for
$N_{\mathrm{f}} = 2$ the anomalous dimension decreases more slowly with
$\beta$. A chiral perturbation theory analysis show that the infrared behaviour
of both theories is incompatible with the breaking of chiral symmetry.
