Now there are studies which confirm that long-term, high intensity physical activity could raise the risk for heart arrhythmias (potentially dangerous irregular heart rhythms). Endurance athletes, such as marathon runners and long-distance high intensity cross country skiers are examples of at-risk individuals for heart arrhythmias and sudden death. Due to their physically high levels of exercise, these athletes may be at risk for atrial fibrillation (fast, irregular heart beat) and bradyarrythmias (very slow, irregular heart rates). Arrhythmias prevent the heart from effectively delivering blood to the body and may cause decreased blood flow to the brain. Loss of blood to the brain for any period of time is potentially deadly. In Froelicher and Myers book, Exercise and the Heart, 5th ed., authors attribute some of the causes of sudden death to a disruption of a “vulnerable plaque” in the artery that, during exercise could be released during a “twisting” motion of the artery. Another theory is that exercise-induced sudden death could be due to abnormal vasoconstriction (spasm) of the artery that occurs in already diseased and narrowed arterial segments.

The London-based study was based on the observation that telomeres (regions of repetitive DNA at the end of a chromosome) in white blood cells erode and shorten during the aging process. Thus their length and quality are biological indicators of human aging, sort of an internal lifeline. Researchers compared the length and quality of the telomeres in 1,200 sets of twins; within each set, one twin exercised regularly and the other was sedentary. Researchers found that the longer, healthier telomeres of the active twin indicated a younger biological age sometimes by as much as nine years when compared to the biological age indicated by the shorter, degraded telomeres of the sedentary twin.

2. Get plenty of sleep. Fatigue, both physical and emotional, can be a deterrent to maintaining a healthy and consistent exercise program. Make sure you are fully rested each day. Most experts agree that seven to nine hours of sleep is ideal.
