Too much exercise can raise early death risk: Study

Exercise for extended periods on a regular basis can raise the risk of heart disease, as per a new study. A research team in Chicago compared heart disease rate among men with moderate exercise to those engaging in increased workout schedules. The study team found nearly twice the risk of heart disease among men exercising 7 hours or more per week compared to men who engaged in moderate exercise.

The study team found that highly active White men were at 86 percent higher risk of a buildup of plaque in the heart arteries by middle age. However, the increased heart disease risk was not noticed among Black men. The study team added that it was surprising to notice higher risk for White men. Deepika Laddu, who co-authored the Mayo study, called for more research in the matter.

The University of Illinois at Chicago and Kaiser Permanente team checked health records for 3,175 men. The study team suggests that high level of exercise could lead to increased stress on arteries which can lead to coronary artery calcification (CAC). The long-term CARDIA (Coronary Artery Risk Development in Young Adults) study checked impact of exercise over long term. Men were tracked from their youth till middle age.

The study group was monitored eight times over a period of 25 years. Study participants were divided in three groups based on their exercise level.

Dr. Laddu said, “Because the study results show a significantly different level of risk between black and white participants based on long-term exercise trajectories. The data provide rationale for further investigation, especially by race, into the other biological mechanisms for CAC risk in people with very high levels of physical activity.”
