the fb by 1 - 2 breaths per min after 20 min of training and then they continued at this
higher frequency for the last 10 min of training. The next training session began at the
highest frequency achieved from the previous session and this was then maintained
for 20 min followed by an increase of 1 – 2 breaths/min for the remaining 10 min.
When fb reached 45, the bag volume was increased by 0.5 L and fb was then reduced
to the beginning value, and the cycle was then repeated. In contrast, the CON group
trained only on cycle-ergometer for 60 min on 50% of PPO. The (PPO) was defined
from VO2maxNor as the last completed work rate plus the fraction of time spent in
the final non-completed work rate multiplied by 30 Watts. The training intensity was
controlled through heart rate monitor and Borg scale. Both groups trained 5
days/week, for 4 weeks.
RESULTS
There were no changes in participants’ anthropometrics parameters (body mass, body
fat) during the training period. Moreover, all PFT parameters did not change with
training in the two groups.
Both groups improved VO2maxNor significantly (p
