Dietary calcium supplementation has been to alter calcium metabolism and prevent hypertension in spontaneously hypertensive rats (SHR). Likewise, microgravity alters calcium metabolism. It is possible that the alteration of calcium metabolism caused by different levels of dietary calcium or microgravity change skeletal muscle properties. The purpose of this investigation was to determine whether spaceflight and/or dietary calcium causes alteration of properties in skeletal muscle from SHR.
Nine-week-old male SHR, fed either high- (2.0%, HCa) or low-calcium (0.2%, LCa) diets, were flown on an 18-day shuttle flight. They were assigned to four groups (n=7/group): control (ground-based) with LCa or HCa, spaceflight with LCa, or HCa. After the spaceflight, the soleus muscle was dissected and analyzed histochemically and biochemically.
Spaceflight caused a slow-to-fast f.. Read More»
