COVID-19 and Swimming Pools

Expert: Swimming pool facilities water unlikely to spread ...

Many states have loosened social distancing restrictions in order to get the economy going again. Now, however, we are seeing a rise in Corona virus cases. We would all like to know what to expect with this pandemic, but there is no way to know for sure how it will play out. My doctor’s practice, USMD Health System, has suggested three possible scenarios:

Scenario One — Begins with an initial wave in Spring 2020 followed by a series of smaller waves of infection that last up to two years.
Scenario Two — Begins in Spring 2020 and is followed by a second, larger wave this fall or winter and a smaller one in 2021. If this happens, communities will likely return to quarantines.
Scenario Three — Begins in Spring 2020 and is followed by what the Center for Infectious Disease Research And Policy (CIDRAP) describes as a “slow burn.” That means there’s no clear pattern. This scenario would likely not cause communities to return to quarantines, but infections and deaths would continue.

No matter the scenario, CIDRAP says we should prepare for another 18-24 months of COVID-19. That means we should continue to practice social distancing, wear face masks in public, and wash our hands often.

Our swimming pools have reopened. Lap swimming, swim lessons and water fitness classes are resuming. What should we know about the safety of returning to the pool and what kind of cautious response should we make? Sara Kooperman (the owner of SCW Mania Fitness conventions) and John Spannuth (the president of the US Water Fitness Association) have both asserted that chlorine used to disinfect pool water kills COVID-19. Craig Lord, the Swimming World Editor-in-Chief, agrees that disinfectants, including chlorine, act on viruses and it is reasonable to expect that would include COVID-19. He adds that pool operators also need to observe strict hygiene protocols, including correct maintenance of pool water and air in the facility, as well as heightened levels of cleaning of adjacent surfaces and environments, since the fundamental mode of transmission of COVID-19 is air and not water.

It is likely that if your favorite pool is reopening, the pool operator is aware of the necessary protocols and has trained the staff properly. Those of us who will be using the pool to teach or participate in a water fitness class also need to do our part. Yes Fitness Music has made the following suggestions:

  1. Outdoor pools are safer because air circulation outdoors is better than indoor air circulation.
  2. Our Texas sun and heat often makes an indoor pool preferable. Ask about the air ventilation. Fresh air is better. If the air is recycled, it should go through a filtration system.
  3. Wear a mask.
  4. Maintain social distancing, 6 feet away from the other swimmers or class participants.
  5. Wash your clothing, towels and masks directly after class.

We can all do our part to protect ourselves and those around us. Enjoy the pool safely!

Keep Your Balance

See the source image

The components of physical fitness are cardio-respiratory endurance, muscular strength and endurance, flexibility and body composition. The skill related components of fitness are balance, agility, coordination, and power. Balance is the ability to maintain equilibrium both while standing and while moving. Balance is important for athletes in gymnastics, football, baseball and other sports, but it is also important for older adults who worry about injuries they may sustain from falling.

Fall risk is the result of deconditioning, not age. To assess your fall risk, stand on one leg without the support of the upper extremities and without bracing one leg on the other. Count the number of seconds you can maintain this position. Time is up when the foot touches the floor or an arm touches something for support. Your chance of falling and sustaining an injury is double if you are unable to perform the one legged stance for 5 seconds. According to the American College of Sports Medicine, balance training may reduce the risk of falling and fear of falling and probably reduces the number of falls. It is recommended that balance training be performed at least 3 times a week, and daily is better. Balance training can be performed either on land or in the pool.

A sample fall prevention strength program on land might include the following exercises: (1) Resisted row with a band, focusing on squeezing the shoulder blades together, to strengthen the upper back and core. (2) Toe scrunches to strengthen the toes. (3) Standing heel lifts to strengthen the calf muscles. (4) Deadlifts, focusing on avoiding bending the trunk, to strengthen the glutes and hamstrings. (5) Chair squats, that is sitting in a chair and standing back up again, and lunges, to strengthen the quads. Also work on walking fast. since the faster older adults can walk, the lower their mortality rate.

Ruth Sova wrote an article for Akwa magazine that described multiple exercises for improving balance in the pool. Here are a few examples: (1) Sit on a noodle like a swing with the feet on the pool floor; turn eyes to the right and hold 10 seconds, and then left. No head movement, only eyes. (2) Sit on a noodle like a swing with the feet on the pool floor and bend to the right further than is comfortable and recover. Notice what is used to recover (legs, head, jerking movement?) and try to use only the core muscles. (3) Sit on a noodle like a horse with the feet on the pool floor and walk forward with feet rolling heel to toe, and nothing moving but the legs. Stop and restart. Stop and walk backwards. (4) Squat with the feet together, with the feet apart, with one foot directly in front of the other, or in a lunge position. Add various arm movements using both arms or one arm. (5) Stand and lift your toes off the floor then roll up on your toes as the chin lowers. (6) Stand with your right heel on the floor and roll the outside edge of the foot to the tips of the toes while turning your head slowly to the left. Repeat with the left foot. (7) Weight shift from side to side and from front to back. (8) Walk on tiptoes, or on heels, or with toes out or toes in. (9) Use unpredictable commands, such as marching in place on tiptoes while circling the right arm. (10) Cross-country ski with the hands on the hips and travel sideways. If you are an AEA member, you can check out the article for more exercises.

The goal is not to be able to perform on a balance beam like Simone Biles. The goal is to avoid becoming one of the 2.8 million seniors who visit the emergency room each year because of a fall. And beyond that, balance training is good for the brain. Memory, language skills, problem solving and decision making are coordinated by the cerebrum. Balance, posture and fine motor skills are coordinated by the cerebellum. The cerebrum and cerebellum are connected by a direct neural link. When an older adult trains for strength and balance, cognition improves.

How to Deal with Disruptive Class Participants

This is an article written by Angie Miller and well worth reading:

We’ve all been there. We’ve come to class prepared and eager to lead, only to discover that there’s that one person- the one who won’t stop talking to the people around them, who answers their cell during class, who takes our yoga, step, or strength training class, but does his/her own workout, or the one who wears headphones during cycle class and rides as if no one else is in the room. Unfortunately, there are a multitude of ways that members can be disruptive, some unknowingly, and some seemingly for attention, but either way, disruptive members disrupt the flow of the class. They compromise safety, hijack our concentration, suck up positive energy, and ironically, they often stand right in the front row ensuring that we couldn’t ignore them if we tried.

So, what do we do? Everyone has their own ideas on what works, based on their comfort zone and the members they teach. Some clubs even have policies to address disruptive members. After decades of teaching I feel like I’ve seen it all (though I know I haven’t), and here are a few things I’ve personally implemented, to manage a member who is disruptive.

  1. Ignore them. I know, I just said that they’re nearly impossible to ignore, but I try this as my first line of defense. If it is attention seeking behavior, as opposed to total oblivion, then I don’t want to reward negative behavior with attention. That’s the educator in me. If that doesn’t work, move on to number two.
  2. Make eye contact. If at all possible, try to make eye contact with them. Not in a confrontational manner, with a smile on your face and a professional demeanor. Eye contact can be a gentle reminder that you’re watching, and you’re reminding them to stay engaged. Ideally, we’re making eye contact with everyone in the room at least once throughout the workout, so this shouldn’t seem unusual. If that doesn’t work, move on to number three.
  3. Address the class as a whole. The key is to not target anyone individually, especially on a live mic. We’re better served to address the class as a whole and remind them: “We don’t have breath for conversation, we’re using our energy for the workout.” “Lets not chat, lets challenge each other to go the extra mile.” You’re addressing everyone in a professional, non-confrontational manner, hoping the culprit of the crime gets the message. If that doesn’t work, move on to number four.
  4. Proximity is key. Often all that’s needed is for us to move about the room as we always do, checking form and alignment, then proximally stand close to where they are and teach from there (only in the moment, not the whole class of course). Proximity is all about presence, which promotes accountability, and it’s a great way to motivate. When we move about the room, most members will step up their game. If that doesn’t work, move on to number five.
  5. Speak to them after class. Mic off, gently, with a professional tone we can ask, “Do you have a minute?” That’s when we say, “I noticed that you seem distracted and I’m wondering how you’re enjoying the workout?” From there, we can guide the conversation to behaviors that promote quality exercise and we can offer guidance on appropriate group fitness etiquette.

One Final Note: One of the best ways to ensure healthy group fitness etiquette is to talk about it at the beginning of class, during our introduction. It’s when I get ahead of any behaviors I’ve witnessed in the past, and I address them before they have potential to compromise my class. It’s when I remind all members: Safety is key, and that means we want to be considerate to those around us: Cell phones off. Save conversations for after class. We’re here to build energy, be engaged, and make the most of every moment.

Keep doing what you love and loving what you do.

Holiday Ideas for Your Class


There is a lot to do during the holiday season: shopping, wrapping presents, decorating, baking, holiday parties and more. You know your water fitness class participants need to maintain their exercise routine to help them manage the holiday stress, but sometimes exercise moves near the bottom of their priority list. Try some of the following ideas to make your water fitness class more festive and encourage everyone to keep coming:

Holiday Music. Break out some holiday music to get everyone in a festive mood. All the fitness music companies have Christmas music playlists for sale. Check out:

(1) Super Happy Xmas Step (128-130 BPM) and Xmas Buzz (135 BPM) at Yes Fitness Music

(2) Tis The Season – Best of Christmas Hits Remixed (130 BPM) and Christmas Hits Remixed (135 BPM) at Power Music

(3) Core Christmas Volume 2 (128 BPM) and Christmas in Motion 3 (135 BPM) at Muscle Mixes

Holiday Themed Games and Activities. Add fun activities at the end of your fitness routine to have everyone laughing and looking forward to the next class. Here are two ideas:

(1) Holiday Obstacle Course – Create an obstacle course with the pool equipment you have on hand, giving it a holiday theme. Station One: Have a participant begin by cross-country skiing to the North Pole, using either drag equipment or foam dumbbells. Station Two: Tie 3 noodles in a triangle to serve as a Christmas tree and have a bucket of small balls nearby. The participant throws the balls into the triangle to “decorate the tree.” Station Three: The participant picks up a paddle or a foam dumbbell and uses it to “stir up the Christmas cookie dough.” Station Four: The participant runs to 3 “elves” who are holding 3 balls. The participant helps in the toy shop by tossing the balls a set number of times back and forth to each elf. Station Five: The participant picks up 2 noodles and puts the ends of each noodle under an arm with the opposite ends sticking out in back. “Santa grabs the free ends and takes a seated position. The participant now takes the place of Rudolph the Red-Nosed Reindeer and pulls Santa’s sleigh to the finish line. If your class is large, half of the participants can man the stations while the other half runs through the obstacle course; then the two groups
change places. If your class is small, have all your participants (but one) man the stations while the “contestant” runs the course. Then that person will take the place of another participant who will take a turn running the course.

(2) Sleigh Races – Have your class members partner up. One partner can be Rudolph and the other Santa. Rudolph then pulls the sleigh as in the obstacle course above, racing with all the other sleighs in the class. After one team wins the race, Rudolph will take a turn being Santa, and Santa will become Rudolph, and the teams race again.

Costumes. This is the perfect time to wear your red swim suit, a Santa hat, a Frosty the Snowman top hat, a red nose or a hat with reindeer antlers.

Holiday Gifts. Show your appreciation for your class by giving them each a small gift. If you are an H20 Wear AquaPRO, you can get coupons for your participants worth 10% off their first purchase of a swim suit. Contact them at to request coupons or to become an AquaPRO member. Some other gift ideas include a Clementine tangerine, a tree ornament, a peppermint candy cane, a Christmas cookie, a package of hot cocoa mix or some kind of homemade goodie. Here is an easy recipe if you would like to make your own treats:

Peppermint Crunch Puppy Chow

Ingredients: 5 cups Rice Chex, 10 ounces melting white chocolate, 1 cup crushed candy canes, 1 cup confectioners’ sugar

Pour the cereal into a large bowl. Melt white chocolate according to the package directions. Pour melted chocolate over cereal, stirring and folding until the cereal is completely covered. Fold in crushed candy canes.

Pour the confectioners’ sugar into a zipped-top bag. Pour the cereal mix in next. Seal the bag and shake until all the cereal is coated with the confectioners’ sugar. Discard excess powdered sugar.

Divide the puppy chow into individual bags and tie with a ribbon.

Merry Christmas!

Buoyant Equipment: Dumbbells

markgrevelding_mug   Foam dumbbells

Nearly every pool has foam dumbbells and participants love to use them! In some places they use dumbbells for every class. Often they grab the largest dumbbells available. Is this a good thing?

The Metroplex Association of Aquatic Professionals hosted Mark Grevelding at a Continuing Education Training on April 21. One of his workshops was a Noodle & Buoy Circuit.  Mark discussed exercise safety with dumbbells. He says that the main thing people do with dumbbells is push them forward and plunge them down.

Every time you submerge foam dumbbells under water, your shoulder stabilizers contract. When you push dumbbells forward you are using them like drag equipment. Your latissimus dorsi and lower trapezius contract isometrically to hold the dumbbells under the water. You get some work for the targeted muscle groups (chest and triceps), but these are not the muscle groups that get most of the work. Plunging the dumbbells down uses the shoulder stabilizers and works the triceps. It is easy to see that too much of this will put undue stress on the shoulders, which can lead to a shoulder injury.

Not only do some people use the dumbbells for every workout, but they also select the largest dumbbells available. They may not be able to keep the shoulders neutral with equipment this buoyant, so the shoulders are elevated. They may not be able to control the dumbbells without throwing their body weight into the exercise. They may have to reduce the range of motion as a result of this loss of control. It is easy to see that too much of this will put undue stress on the shoulders, which can lead to a shoulder injury.

So what are foam dumbbells good for? Well, I’d love to show you some pictures of exercises with the dumbbells, but when I Googled pictures of water exercises with foam dumbbells, all they had were pictures of pushing them forward and plunging them down! So you’ll have to use your imagination. Choose a size that you can manipulate while keeping the shoulders relaxed and the spine in neutral alignment. Relax your shoulders and fingers between each set. Use the dumbbells for only part of a class.

  1. Chest. In a lunge position, lean forward 45 degrees and perform a chest fly, like clapping your hands, or a chest press, pushing at an angle toward the floor.
  2. Lats. In an upright lunge position, perform a lat pull-down, like jumping jacks arms.
  3. Triceps. In a squat or lunge position, with elbows by the waist, perform a triceps extension. Or plunge the dumbbells down at the sides.
  4. Squats and lunges. Hold the dumbbells down at your sides while you perform these exercises to add resistance as you lower the body toward the floor.
  5. Calf raises. Hold the dumbbells down at your sides while you rise up on your toes to add resistance as you lower your heels back to the floor.
  6. Plank and side plank. Hold both dumbbells directly under the shoulders for the plank and one dumbbell directly under the shoulder for a side plank.

There are a lot of muscle groups missing from this list, like the upper back, shoulders and biceps. That’s because foam dumbbells only add resistance when you are pushing them toward the pool floor. The buoyant dumbbells want to float to the surface of the water, which means there is no resistance for any exercise that involves lifting them. Another thing missing from this list is using the buoyant dumbbells for support in a suspended position. When the body is suspended from dumbbells held in the hands or placed under the arms, the shoulders are unacceptably loaded, the tendons are pinched, and nerve damage may occur in the arm pits (Ivens and Holder, Do No Harm, 2011).

The bottom line is that foam dumbbells are a lot of fun and they offer some good resistance for a limited number of exercises. For more information on using dumbbells, including a chart showing which muscles are being trained with various exercises using buoyant equipment, see my new book Water Fitness Progressions. The book also contains lesson plans using dumbbells for both shallow water and deep water classes. The book can be ordered from Human Kinetics (the publisher) or from Just click on whichever source you wish to order from and the link will take you there.
