Exercise triggers hormesis, conditioning hearts against damaging consequences of subsequent ischemia-reperfusion (I/R). We test whether “low-stress” voluntary activity modifies I/R tolerance and molecular determinants of cardiac survival. Male C57BL/6 mice were provided 7-day access to locked (7SED) or rotating (7EX) running-wheels before analysis of cardiac prosurvival (Akt, ERK 1/2) and prodeath (GSK3β) kinases, transcriptomic adaptations, and functional tolerance of isolated hearts to 25-min ischemia/45-min reperfusion. Over 7 days, 7EX mice increased running from 2.1 ± 0.2 to 5.3 ± 0.3 km/day (mean speed 38 ± 2 m/min), with activity improving myocardial I/R tolerance: 7SED hearts recovered 43 ± 3% of …

Osteoporosis, “the silent killer,” is responsible for 8.9 million annual fractures. Although not bound to these factors, osteoporosis typically targets females that are post-menopausal and have a family history of the disease. Osteoporosis is caused by a decrease in bone mass density. Physical activity and exercise and often spoken about when the topic of osteoporosis is discussed because of the impact they have on maintaining bone mass density in an effort to delay osteoporosis. This paper first provides an overview of osteoporosis, explanation of methods of diagnosing osteoporosis, risk factors, complications and treatment for osteoporosis. Topics covered include, bone mass …
