N2 - Purpose: This study examined the effect of resistance training (RT) by itself and in combination with supraphysiological administration of nandrolone decanoate (ND) on the inflammatory, apoptotic, and oxidative stress response in cardiac tissue. The effect of the training and androgen intervention on adiponectin expression, a potential cardio protectant was also examined. Methods: Forty male C57Bl/6J mice, 3 months of age were randomized into four groups (n = 10 per group). Two groups of animals performed a 3-day per week RT program for 7-weeks, while the other two groups remained sedentary (SED). The RT and SED animals were further randomized into an androgen group (RTA and SEDA, respectively) or a sham group (RTS and SEDS, respectively). Animals in the RTA and SEDA groups received 38-mg·kg−1 injected once per week. Mice from RTS and SEDS received sham injections. Results: Main effects for group indicated that RT resulted in significant elevations in NFκβ (p < 0.001), glutamine peroxidase (GPX) (p = 0.007) and adiponectin (p < 0.001). Main effects for treatment indicated that ND administration resulted in greater elevations in NFκβ (p = 0.01) and TNF-α (p = 0.017). In addition, TNF-α expression was greater in RTA compared to RETS (p = 0.006) and the adiponectin response in RTA was greater (p's < 0.05) than all other groups. A significant correlation was noted between average training volume during the RT program and GPX expression (r = 0.716, p < 0.001). Conclusion: Results indicate that RT and ND administration can increase markers of apoptosis and inflammation. Elevations in adiponectin expression suggest that it may act as a compensatory mechanism supporting cardiovascular health.
