Abstract:
Cardiac rehabilitation reduces the risk factors and
improves the aerobic exercise capacity of patients after
they have experienced cardiac events. This study
compared the effects of two types of interval training in
patients with myocardial infarction (MI). A single-blinded
randomised controlled trial was conducted on 26 patients
with MI which included 16 males and 10 females. After
screening via non-probability convenience sampling,
patients were randomised into two groups using toss and
trial method. The control group was given aerobic interval
training (AIT), consisting intervals of stationary cycling
and walking on the treadmill. The experimental group
received both AIT as well as resistance interval training
comprising exercises of the upper and lower limbs. After
6 weeks, the outcomes of peak oxygen uptake (VO2) and
6-minute walk test distance (6MWT) were measured
against the baseline. Non-parametric tests were applied
for statistical analysis. In the group comparison, the
experimental group showed significant improvement in
peak VO2 and 6MWT (p=0.003 and 0.003 respectively), as
well as in the quality of life measures. The combination of
resistance interval training plus AIT proved more effective
in improving cardiac outcomes and aerobic capacity.
