The effect of eight-week resistance training and consumption of grape seed nanoparticles on mitochondrial biogenesis of heart tissue in the myocardial infarction model

The consumption of grape seed nanoparticles extract can control cardiovascular risk factors. Exercise plays a protective role against cardiovascular disease. Therefore, the aim of the present study was to investigate the effect of eight-week resistance training (RT) and the use of grape seed nanoparticles on mitochondrial biogenesis of heart tissue in myocardial infarction (MI) models.

In this experimental study, 25 rats were randomly divided into five groups including (1) control (C), (2) MI, (3) MI+RT, (4) MI+grape seed, and (5) MI+RT+grape seed. MI was induced by subcutaneous injection of isoprenaline (85 mg/kg). Grape seed nanoparticles were daily administered at a dose of 150 mg/kg for 8 weeks, and RT was performed 5 days a week. Finally, data were analyzed using the one-way analysis of variance (ANOVA) and Tukey’s post hoc tests (P≤0.05).

MI models showed decreased expression of PGC-1α, PPARγ, and UCP-1 genes in cardiac tissue (P=0.001). However, RT combined with the use of grape seed nanoparticles had a significant effect on increasing the expression of PGC-1α (P=0.001), PPARγ (P=0.002), and UCP-1 (P=0.003) genes in the heart tissue of MI model mice.

The consumption of grape seed nanoparticles along with RT has more effects on improving the expression of PGC-1α, PPARγ, and UCP-1 genes in MI than either alone. Therefore, the use of grape seed nanoparticles together with RT is recommended in case of MI.
