Symptoms of lead poisoning are varied. They may affect many parts of the body. Most of the time, lead poisoning builds up slowly. It follows repeated exposures to small quantities of lead. Lead toxicity is rare after a single exposure or ingestion of lead.
The new formula for women, based on the new research, is 206 minus 88 percent of age. At age 50, the original formula gives a peak rate of 170 beats per minute for men and women. The new women's formula gives a maximum heart rate of 162 beats for women. Many men and women use their peak heart rate multiplied by 65 to 85 percent to determine their upper heart rate when exercising.
The basic formula for calculating maximum heart rate is to subtract your age from 220. Your target heart rate during exercise ranges from 50 percent to 85 percent of your maximum heart rate, depending on the intensity of the activity.However, this method for calculating maximum heart rate and target heart rate zones might be inaccurate for well-conditioned individuals or athletes.hile the normal resting heart rate for adults ranges from 60 to 100 beats per minute, conditioned athletes and other highly fit individuals might have normal resting heart rates of 40 to 60 beats per minute.
