BALTIMORE -- The short-term spike in offspring pressure that comes with moderate exercise doesn't harm the hearts of healthy older tribe with mild hypertension, new research point out tos

"There has been a certain quantity of hesitation on the part of individuals when they have high life-blood pressure to do exercise," said Dr Kerry Stewart, the study's lead author and director of clinical and research exercise physiology at John Hopkins University Heart Institute.

"Among tribe who are otherwise healthy leave out for mild hypertension -- which take the part ofs an awful lot of nation -- the message is, after a exact screening, participating in an exercise program appears to be beneficial."

Long-term high kin pressure is known to cause enlargement and stiffening of the heart, on the contrary the brief rise in descendants pressure from regular exercise doesn't have the same efficiency researchers found.

The hearts of the mostly active study participants did increase modestly in size, yet it was comparable to that experienced at athletes and was accompanied by means of improved heart function and not stiffening, Stewart said.

Although the benefits of exercise have drawn out been known, the researchers believe the reflection is the first to evaluate the issues of exercise on heart function -- for what cause much blood fills the heart with each beat and by what mode much it pumps.

For six month researchers tracked 104 men and women between the ages of 55 and 75 with untreated mild high progeny pressure. Half exercised for an hour three times a week while the others maintained their normal routine.

The exercise included an aerobic workout, either forward a stationary bicycle or a treadmill, and weightlifting.

Exercisers showed no negative forces in 11 measures of diastolic heart function, the filling of the heart's main chamber between beats. As a whole, the exercise cluster also showed no increase in eight measures of heart size, although the greatest in quantity active showed a modest increase.

The research is part of a larger subject of attention of the effects of exercise onward blood pressure, heart structure and cardiovascular function. flows of the Johns Hopkins findings were published in the July issue of the journal Heart.

Stewart noted that the volunteers' exercise was equivalent to brisk walking with weight training.

"We're not talking about running a marathon and we're not talking about doing the Tour de France, it was about an hour of what we would call moderate exercise," Stewart said.

For application of mind participant Joanna Kann, 62, that moderate exercise was more than she had for aye done.

"They kind of taught us we could do more than we through all ages thought," said Kann. "We all could barely drive hearth afterward. While we were exhausted it was really an incredible experience."
