"It’s no secret that exercise is good for the heart, but also for the brain. A new review reported in Circulation, journal of the American Heart Association, which focus on the precise amount of physical activity, states that practicing physical exercice (probably moderately) at least for 2 hours and 30 minutes throughout the week, and better yet, 5 hours, has very interesting effects on heart health. In the first case, the participants had a 14 percent lower risk of coronary heart disease (CHD) compared those who don’t exercise. In the second case, the risk was 20% lower than the non-physical. In a study printed in the August 2, 2011, issue of Neurology — American Academy of Neurology, researchers show that smoking, obesity, high blood pressure and diabete may cause brain lowering and rapidly involve cognitive problems that remains. This study was conduct with 1352 participants with an average age of 54. “These factors appeared to cause the brain to lose volume, to develop lesions secondary to presumed vascular injury, and also appeared to affect its ability to plan and make decisions as quickly as 10 years later”, said study author C. DeCarli, MD. “In the middle age” (so that’s biologically relevant for everybody) high blood pressure, diabete, obesity, overweight and smoking lead people to have worse results in tests of decision making, planning, executive functions. Damage occur in the brain and its volume decrease. So, 300 minutes physical training per week would be a good start to avoid those problems and protect the heart — but don’t force too much."
