Attitudes toward exercise during pregnancy have changed dramatically over the past 20 years. Recent studies show that, in most cases, exercise is safe for both the mother and fetus during pregnancy, and support the recommendation to initiate or continue exercise in most pregnancies. This report discusses the rationale behind the ...

Fatigue and insomnia are problems for patients with cancer. Research findings show that aerobic exercise decreases cancer-related fatigue. Because patients with cancer who have skeletal muscle wasting may not obtain maximum benefit from aerobic exercise training, exercise programs may need to include resistance training. Thus far, testing exercise as an ...

Sustained bouts of maternal exercise during pregnancy cause an acute reduction in oxygen and nutrient delivery to the placental site. The decreased flow also initiates a slight fall in intervillous and fetal pO2 which initiates a fetal sympathetic response. This, coupled with hemoconcentration and improved placental perfusion balance, maintains fetal ...

The results of most recent studies have generally indicated an improvement in mood after participation in aerobic exercise. However, only a few researchers have compared mindful modes of exercise with aerobic exercise to examine the effect of 1 single session of exercise on mood. In the present study, the authors ...

Fatigue and impaired physical performance are common and sometimes serious problems of cancer patients during and after treatment. To avoid fatigue, cancer patients are often advised to rest and downregulate their daily activities. However, these recommendations can cause paradoxical results. Since inactivity induces muscular wasting, prolonged rest can result in ...
