The participants performed warm-up exercises in the
beginning of each training session (10 repetition of each
exercise with 50% of 1 repetition maximum (RM)). At the
beginning and halfway through the intervention period, the
participants were tested for optimizing the training intensity
and the loads were progressively increased according to the
principle of periodization and progressive overload [25]. The
intensity of the program increased gradually from 20 RM at
the beginning of the intervention period to 8 RM further
along in the process.
