(CNN) – Letters evaluating the physical health of Mitt Romney and Paul Ryan were released by their physicians Friday, both indicating that the GOP's presidential and vice presidential nominees are in top condition for their respective ages.
Romney's letter, issued by Randall Gaz of Massachusetts General Hospital and Harvard Medical School, noted the candidate last underwent a physical exam on August 9, which showed the candidate a "healthy appearing, energetic, strong, physically fit male."

Romney weighed 184 pounds in August and had a blood pressure of 130/80 – putting the candidate in the "prehypertension" range, as defined by the National Institutes of Health. Gaz, in his letter, wrote that Romney had mildly elevated triglyceride levels, for which he takes a daily 10 milligram dose of the drug Lipitor.
Other vital statistics included a resting heart rate of 40 beats per minute and a body temperature of 98.4 degrees.
Other information contained in the letter included the fact that Romney "totally abstains from drinking any alcoholic beverages and does not use any tobacco products or illicit drugs," a condition of his Mormon faith.
The letter also notes Romney suffered a concussion from a car accident in 1968, during his time as a missionary in France. That accident came as he was driving the mission president and his wife during a six-hour ride between Paris and the south of France. Their car was hit by what was believed to be a drunken driver. The mission president had to return to the United States because of his injuries, and his wife was killed.
Romney also had an appendectomy in 1965, and stitches on his hand in 1987.
Ryan's physical assessment, from the attending physician of the U.S. Congress Dr. Brian Monahan, painted a similarly healthy portrait of the GOP vice presidential nominee.
Monahan noted Ryan occasionally suffers from airway hypersensitivity, which the doctor said he treats with an inhaler. He also wrote that the Wisconsin congressman experienced back and knee injuries.
Vital statistics were all healthy for Ryan, whose father and grandfather died in their fifties. He weighs 163 pounds, stands 6' 2" tall, has a resting heart rate of 59 beats per minute, and a blood pressure of 121/62.
Ryan, 42, is well known for his fitness routine P90X, and has led sessions of the cross-training regime in the House gym.
"My dad died of a heart attack at 55, my grandfather at 57, so I've always had this incentive to stay healthy," Ryan told CNN's Gloria Borger last year.
Romney, 65, is often seen partaking in water sports at his lakefront home in New Hampshire. He is known to use elliptical machines for regular workouts, but told CBS in August he would consider trying Ryan's exercise of choice.
"I've never tried that," he said. "I might have him show me how to do it someday. I get on the elliptical or the treadmill or the stationary bike for about 40 minutes and that's about it for me. But that workout of his, he's in pretty good shape."
