100-year-old Japanese female swimmer swam 1,500 meters in Masters Swimming Meet in western Japan


100-year-old Japanese female swimmer swam 1,500 meters in Masters Swimming Meet in western Japan




TOKYO (Xinhua) -- Mieko Nagaoka, a 100-year-old Japanese female swimmer, finished a 1,500 meters swim in one hour, 15 minutes and 54.39 seconds in the masters swimming competition in Matsuyama, western Japan...

Mieko Nagaoka, born in 1914 and who lives alone in south Japan, took up swimming at the age of 82 to recover from a knee injury. Her story teaches us a simple but often overlooked lesson -- it's never too late to start something new and succeed.

In the beginning, Nagaoka didn't know how to swim. She used to come to the swimming pool to do exercises for her knee. At 82, she started to learn and swim on her own. Because she performs in a Noh -- Japanese traditional dancing dramas, this was also an incentive to learn how to swim so that she would keep in shape for the plays.

Aged 100, she is now Japan's oldest swimmer and even comes to compete at the FINA masters world championships. When she was 84 years old, Nagaoka started masters swimming in Japan. At 88, she made her first appearance at the masters worlds in 2002 in Christchurch of New Zealand and took the bronze in the 50m backstroke. She was back for more in 2004 in Riccione of Italy where she won three silver medals (50m, 100m and 200m backstroke).

She achieved national recognition in Japan when at 90 she set a national record in her pet event, the 800m freestyle. Fresh from her success, she started training with a coach, taking private lessons and trying to improve her record-breaking performance.

Her endeavors have paid off since at 95, she brought it to a whole new level, creating her first masters world record in the 50m backstroke. She currently holds 24 world records and plans to win more medals in both long and short course.

Nagaoka trains four times a week, each for two hours. She actually likes longer distances because she swims slowly and is able to keep her own pace.

In Nagaoka's family, swimming transcends every generation, from her son to grandchildren, and she strongly encourages other swimmers to keep swimming as long as possible.

Good News for Swimmers: Swimming lowers blood pressure


Swimming lowers blood pressure



MANY older adults like to take a dip a pool, and now a small study suggests it can be good for their blood pressure.

Researchers found that among 43 older men and women, those who started swimming a few times a week lowered their systolic blood pressure — the "top" number in a blood pressure reading.

On average, the swimmers started the study with a systolic blood pressure of 131 millimeters of mercury (mm Hg). Three months later, it was 122 mm Hg.

Normal blood pressure is defined as an average reading no higher than 120/80 mm Hg. Readings of 140/90 or higher are considered high blood pressure, and anything in between is considered "pre-hypertension."

Swimming is often promoted as a good way for older people to exercise, since it's easy on the joints and it's not likely to cause overheating. And many follow that advice: after walking, swimming is the second-most popular form of exercise among the older set.

But there's been little research into the health benefits of swimming — though a number of studies have suggested that it's as safe for older adults as walking and bicycling, said Hirofumi Tanaka, senior researcher on the new study.

Published in the American Journal of Cardiology, the research appears to be the first to demonstrate that swimming can improve older adults' blood vessel function and curb their blood pressure.

"Swimming is a very attractive form of exercise," Tanaka, a researcher at the University of Texas at Austin, told Reuters Health in an email.

"It's easily accessible and inexpensive," Tanaka noted. "And because it does not involve bearing of body weight, due to the buoyancy of water, it is friendly to knee and ankle joints."

The study included 43 adults, with an average age of 60, who had high blood pressure or pre-hypertension but were otherwise healthy.

The researchers randomly assigned them to either have supervised swimming sessions or learn relaxation exercises. Over 12 weeks, the swimmers got in the pool three or four times a week, gradually working their way up to 45 minutes of swimming at a time.

By the end of the study, the swimmers had shaved an average of nine points from their systolic blood pressure. In contrast, that number did not budge in the relaxation group.

The picture was similar when the researchers had the study participants wear portable monitors that tracked their blood pressure over 24 hours. On average, the swimming group had a 24-hour systolic blood pressure of 119 mm Hg — down from 128 mm Hg at the study's start.

Tanaka's team also used ultrasound tests to measure how well participants' blood vessels were dilating in response to blood flow. Again, they found improvements in the swimming group, but not in the relaxation group.

The study was small, and it's not clear whether the blood pressure reduction lasts — or whether it translates into a lower risk of heart attack or stroke down the line.

But the results line up with what experts already recommend for older adults' heart health: get regular moderate exercise, along with a healthy diet.

Tanaka said that as long as an older adult has gotten the go-signal to exercise moderately, swimming should be a safe activity. But if you're sedentary, check with your doctor before becoming newly active.

There was a time when swimming was considered potentially risky, Tanaka noted, because being in cold water "elicits cardiovascular changes."

But most studies have indicated that swimming at your local pool would be as safe as a walk around the neighborhood.
