Does resistance training, combined with aerobic training, further improve cardiovascular fitness in cardiac rehabilitation patients?

The primary aim of this research project was to focus on the outcomes and benefits of performing a combined cardiovascular exercise and resistance training programme in post-myocardial infarction participants. Study methods involved 18 participants (15 males, mean (M) age 61 years (SD ± 6.6), (range 45 – 72 years), and three females (M= 51 ± 8.8 years, range 43 – 63 years). Participants were randomly selected into standard care (SC) or standard care plus (SCP) groups. Each group performed 30 minutes of supervised cardiovascular exercise over a six week period; the SCP group additionally performed one set, of three resistance exercises, for 10 repetitions. Dependent t-test data gathered from a 10 metre incremental shuttle walking test prior and post-intervention demonstrates an increase in mean walking distance; the SC group by 46.9% (p = 0.01), the SCP group by 24.4% (p = 0.001). Independent t-test data demonstrates no significant findings between the groups, pre-intervention (p = 0.10), or post-intervention (p = 0.74). Significant differences were found between the pre and post-strength variables, Leg Press (p = 0.005), Back Pull-Down (p = 0.005), and the Chest Press (p = 0.007). The main conclusion to be drawn from this study is the necessity of a need to apply specificity to exercise training. A recommendation from this study would be to ensure that strength training is introduced at an appropriate time for an individual and that this component of physical training receives as much endorsement as cardiovascular exercise
