EFFECTS OF COMBINED AEROBIC AND RESISTANCE INTERVAL TRAINING VERSUS AEROBIC INTERVAL ON QUALITY OF LIFE, FATIGUE AND DYSPNEA IN POST MI PATIENTS

Abstract

PURPOSE:

The aim of the study will be to establish that combination of aerobic and resistance interval training has a better effect in improving quality of life, fatigue and dyspnea compared to aerobic interval training.

METHODS:

Informed consent was taken after which randomized controlled trial was conducted at Armed Forces Institute of Cardiology between September 2019 and February 2020. There were 30 participants in the study who were enrolled based on inclusion and exclusion criteria. Both male and female aged 35 to 75 with a single MI in terms of time were included and those with ejection fraction less than 40 percent and cardiac surgery were excluded. By lottery technique, the respondents were randomly split into the interventional (n=15) and control (n=15) group. Both groups of patients engaged in 3 bouts of aerobic interval training that was conducted at 65 -85% of VO2max and resistance exercises were incorporated at 40 50 percent of 1RM to interventional group and 3 days/week over a period of 4 weeks. Before and after the 4 weeks of training, the quality of life, fatigue as well as dyspnea were evaluated using Mac New Quality of Life, Fatigue Severity Scale and Modified Borg Rating of Perceived.

RESULTS:

The average age of interventional group was 56.47 with a standard deviation of 9.576 and that of control group was 55.73 with a standard deviation 9.830. Following 4 weeks of training statistic significant difference was found between the groups in all three domains of quality of life (p=<0.05). There was no significant difference between interventional and control group with respect to dyspnea and fatigue (p=>0.05). Comparison between the groups on QoL, fatigue and dyspnea showed a significant difference in both the interventional and the control groups (p=<0.05).

CONCLUSION:

The present research concludes that aerobic and resistance interval training combination is the one that is better placed in the context of quality-of-life improvement. On the contrary, the same effect was observed on fatigue and dyspnea in both groups.
