Even more so is the fact that Ms. Barnea, who lives in Palo Alto, Calif., is a record-breaking swimmer and senior athlete who competes in sanctioned races for her age group in events around the world.
At the 2017 United States Masters Swimming Spring Nationals, in Riverside, Calif., she won three gold medals in the women’s 70-to-74-year-old age group. These included the 100-yard and 200-yard breaststroke finals and the 200-yard individual medley finals.
Hundreds of thousands of senior athletes like Ms. Barnea compete regularly in athletic events throughout the world, including the National Senior Games Association, United States Masters Swimmingand USA Track & Field Masters programs. Races are divided into five-year age increments starting at age 35 and ending at 100-to-104. Generally, the athletes range in age from 50 to 100.
A recent documentary, “Impossible Dreamers,” produced by Eric Goldfarb and Erik Howell through Better World Film Group, follows senior athletes who are amateurs as they train for competition. In addition to Ms. Barnea, the 75-minute film (which can be viewed on Netflix and Amazon) spotlights a 91-year-old tennis player, octogenarian racewalkers and septuagenarian sprinters, weight lifters and boxers.

Ms. Barnea is among the youngest featured in the movie. Donald Cheek, known as Doc, a resident of Clovis, Calif., is an international gold medal Masters sprinter at 87. Mr. Cheek repeatedly wins in the 85-to-89 division, competing in the 50-, 100-, 200- and 400-meter events. Last October, in the Huntsman World Senior Games in St. George, Utah, he set the games’ record for 100 meters at 17.38.
Ms. Barnea’s latest athletic challenge is the 17th FINA World Masters Championships in Budapest this month. To prepare, she swims double workouts and hits the gym three or four times a week. “I don’t want to be another Mark Spitz or Michael Phelps,” Ms. Barnea said. “I just want to be first.”
She schedules her workouts around the time she spends with her three grandchildren and her part-time job as a foreign language tutor for the Palo Alto Unified School District.
It’s “kind of boring swimming back and forth, back and forth, but when you have a goal, it’s not,” Ms. Barnea said. “It’s like meditation to me. It’s very peaceful. There is something very soothing about being surrounded by water.”
For many older people, though, exercising can be a challenge. That’s why the producers of “Impossible Dreamers” decided to give viewers workout tips.
“We didn’t want viewers to feel inspired by the film and then go back to their regular habits the next day,” said Eric Goldfarb, the filmmaker. “We caught up with several of the athletes after the film’s production to get their demonstrations on safe exercises for older adults; different movements that are simple, maximizing bodily benefits and fun.”
The message, Mr. Goldfarb said, is that “no matter where you are in your life, you do what you can” with regard to fitness.
“You exercise as much as you can without going beyond what your body is able to do,” he said. “The athletes in this film are not superheroes. They are all plagued with injury and real-life circumstance that happens to everybody, and they get through it.”
A few years ago, Ms. Barnea had abdominal surgery and needed to rebuild her swimming regimen slowly. “I could barely swim across the width of pool, but every day I added a few laps, and got stronger and stronger,” she said.
A rotator cuff injury sustained in a dog-walking mishap, when she was pulled abruptly toward a neighbor’s cat, still makes her wince and prevents her from competing in the butterfly, one of her signature events.
But she keeps on stroking. This year, she will enter an estimated 20 competitions. “You need to trust yourself, trust the hopes and not the fears, and keep going around the obstacles,” Ms. Barnea said.
Ursula M. Staudinger, a life span psychologist and researcher at the Robert N. Butler Columbia Aging Center at Columbia University, said that exercising in older age is crucial to physical and mental health.
“Our bodies are made for being used,” she said. “Physical fitness and activity improves brain function. Anyone who is keeping up physical activity — both the aerobic part, which is really important, and the strength and balance and flexibility — is reducing the risks and buffering the decline that is going on.”
For Mr. Cheek, the nation’s fastest 100-meter sprinter in his age group, there is “a pride and a mental discipline that carries over into your whole lifestyle,” he said. Consistent exercise, said Mr. Cheek, who is a part-time professor of social psychology at California State University, Fresno, allows you to have “a body that can perform for you any time you want.”
Mr. Cheek, who grew up in Harlem and earned a Ph.D. from Temple University, has been running track since his days at Cardinal Hayes High School in the Bronx. “The track represents freedom to me,” he said. “It is a very clear measurement of what I am. It tells me I have guts, character, that I have what it takes.”
Mr. Cheek, for example, starts his routine with a variety of relaxed stretches. He and his wife, Patti, are shown lying in bed wearing workout clothes; they lift their legs in the air, curl their toes and spin their ankles in each direction.
Mr. Cheek is also shown skipping with his grandchildren; he recommends two minutes of skipping. “This develops a certain rhythm for your body,” he said. “Skipping is what children do, and it’s fun. It makes you smile.”
Then Mr. Cheek moves on to high-step skipping, with the emphasis on lifting his knees. He also recommends standing in place and moving your feet as fast as you can. “Do it rhythmically, and move your arms as fast as you can,” he said.
In the documentary, Mr. Player is shown pacing on a treadmill, lifting light weights, doing situps and running rapidly in small steps. “You’ve got to keep the body moving like a piece of elastic,” he says in the film.
These exercises help keep him performing well on the golf course. “All you need is 10 minutes on the treadmill every day,” he says.
For these seasoned athletes, there’s seemingly no fear of getting older. “People usually don’t want to tell their age, but not me,” Ms. Barnea said. “I can’t wait to tell them I am moving up to my next age group for competing. I can break new records when I’m the youngest one in the race.”
