| Summary: |
Background. Asthma is an infl ammatory
airways disease characterized by widespread
narrowing of the airways, which is caused by
bronchospasm, mucosal edema, and mucus
hypersecretion are strong relapse, recurrent and
reversible. Value of peak expiratory fl ow ( PEF )
is one indication of airway obstruction. Asthma
management in addition to pharmacotherapy
also do sports like gymnastics with asthma
and exercise bike. Exercise statis bike improves
cardiorespiratory work include increased heart
rate. Exercise statis bike can gradually increase
the intensity of peak expiratory fl ow and reduce
the frequency of recurrence.
Method. The aim of research was to assess the
eff ectiveness of the exercise bike to increase
Peak expiratory fl ow (PEF) and the frequency
of recurrence than gymnastics asthma. This
study used a quasi- experimental method with
pretest- posttest design with control group.
Number of respondents by 28 people. PEF
value measurements used a peak fl ow meter
Philips respironics, and note the frequency
of recurrence with observation record sheet.
Measured before exercise and after axercise.
Result. The results of this research showed
a signifi cance value (P= 0.000) of PEF, the
frequency of recurrence (p=0.001) (p<0.05)
signifi cantly diff erent before and after the
exercise bike. Unpaired t-test signifi cance
value of PEF (p=0359), Frequency of recurrence
(p=0.050) (p> 0.05). There were no signifi cant
diff erences after exercise between the treatment
and comparison groups. Conclusions. Exercise
statis bike can increase the value of PEF and
reduce the frequency of recurrence in patients
with asthma.
