Maintain Your Flexibility

0

Some of my water fitness class participants enjoy stretching at the end of class and a few leave the pool before we get to the stretches. Are they missing anything important?

The American College of Sports Medicine recommends incorporating stretching exercises into your workouts 2-3 days a week but notes that daily stretching is most effective. They recommend that stretches be held for 10-30 seconds. Stretches that are held for 10-30 seconds are called static stretches. Stretching can also be dynamic. This means that you move a joint slowly through its full range of motion.

Stretching is a way to improve flexibility. Loss of flexibility results in a slower walking speed, smaller steps while walking, back pain and increased risk of falls. Improving flexibility reduces your risk of getting injured during physical activity. Muscles that are less tense are likely to have fewer aches and pains. You are less likely to have muscle cramps. Increasing your range of motion helps with balance. Flexibility and strength are two sides of the same coin. Stretching lengthens the muscles while strength training contracts the muscles. Performing both types of exercises makes you more physically fit.

There is a type of dynamic flexibility training that involves both stretching and contracting the muscle group being targeted. It is called Proprioceptive Neuromuscular Facilitation or PNF for short. In PNF an arm or a leg moves in a diagonal pattern. In the first illustration above, the right arm starts at the upper left front corner (left shoulder) and moves to the lower right rear corner. In the second illustration, the right leg starts at the upper left front corner and moves to the lower right rear corner. The opposite motion from the lower left front corner to the upper right rear corner is also performed. PNF stretching improves range of motion and muscular strength at the same time.

Ai Chi is another form of dynamic stretching. It was developed in Japan in 1993 by Jun Konno and introduced to the United States by Ruth Sova. Typically performed in shoulder depth water, Ai Chi moves arms and legs through a full range of motion while focusing on breathing patterns. You can find a video of Jun Konno performing Ai Chi on YouTube. A number of variations of Ai Chi have been developed. I find Ai Chi wonderfully relaxing and created a variation to use with my deep water classes. Ruth Sova is compiling the variations, including mine for deep water, which she will publish later in 2020.

Static stretching, dynamic stretching, PNF and Ai Chi can all be performed in a water fitness class to meet the American College of Sports Medicine’s recommendations on flexibility exercises. If you would like some ideas for stretches for various muscle groups to get you started, see pages 18-19 for shallow water and pages 175-176 for deep water in my book Water Fitness Progressions.

Make Your Heart Stronger with Intervals

1

The way to make your heart stronger is to make it beat faster. Since there is a direct correlation between how fast your heart is beating and how fast you are breathing, making your heart stronger means exercising at a pace that makes you breathe faster than normal. Interval training is a popular way to meet this objective.

Interval training is alternating bouts of fast paced exercise with slower paced exercise. The fast pace is called work and the slower pace is called recovery. One period of work plus one period of recovery is called a set. A group of sets is called a cycle. The chart above shows a cycle of five sets of intervals. If you are jogging, your work might be running and your recovery could be walking. In a water exercise class, your work might be performing an exercise faster, but there are other ways to increase intensity.

The basic aquatic exercises of jog, kick, cross-country ski and jumping jacks can all be performed at a somewhat easy level. Your breath will be faster than standing still, but you can still do the exercises while talking or even singing. To increase the intensity to a moderate level, increase the range of motion, that is, make the moves larger. Your breath will be a little faster and although you will still be able to talk, it will be harder to sing. To increase the intensity to a somewhat hard level, increase the speed of the exercise. Try not to lose range of motion as you go faster. For many people, taking the exercise to a suspended position is also somewhat hard. With faster moves or suspended moves you may be able to talk, but you will be breathing hard enough that you won’t really want to talk. To work at a hard level, add acceleration. This could be by jumping but you can also perform the exercise with power. The harder you push against the water the harder the water pushes back. Power moves are slower but the effort is greater. At this level, you might be able to grunt in response to a question and you will feel like you can only keep that pace for a short time.

Each variation is performed for 4 counts.

Each variation is performed for 4 counts.

The work period and the recovery period of an interval can last for a few seconds up to a few minutes. Usually the recovery period is longer than the work period so that you can recover fully before starting the next work period, but you can have a reduced recovery period for an added challenge. Some ways to time the intervals are:

  • Interval 30: 30 seconds of work to 90, 60 or 30 seconds of recovery
  • Interval 40: 40 seconds of work to 80, 60 or 40 seconds of recovery
  • Interval 60: 60 seconds of work to 120, 90 or 60 seconds of recovery
  • Reduced Recovery Time: 1, 2 or 3 minutes of work to 30, 60 or 90 seconds of recovery
  • Rolling Intervals: work for 1 minute, increase intensity for 1 minute, and increase intensity again for another minute
  • Surges: work for 45 seconds and increase intensity for 15 seconds to 60 seconds of recovery
  • Tabata – 20 seconds of work to 10 seconds of recovery 8 times

These ways to time intervals, plus additional timing options, are explained in my book, Water Fitness Progressions. The book also includes sample lesson plans that use these timing options with variations for moderate, somewhat hard or hard intensities. To order the book from the publisher, click on the title.

What is fitness?

1

Frequently fitness is equated with a number on the bathroom scale, but fitness is much more than body mass index. Physical fitness has two components, the health-related components and the skill-related components. The health-related components are cardiorespiratory endurance, muscular strength, muscular endurance, flexibility and body composition. The skill related components are agility, balance, coordination and power.

Cardiorespiratory endurance. This is the ability of your heart to deliver oxygen to your working muscles for a sustained period of time. Your muscles need oxygen to burn the calories you use during aerobic exercise. The American College of Sports Medicine recommends that you get 150 minutes of aerobic exercise a week to keep your heart strong. Obviously, everyone wants a strong heart muscle! Cardiorespiratory endurance allows you to participate in recreational activities, play with grandchildren and do all the walking you have planned for your vacation.

Muscular strength. This is measured by determining what is the heaviest weight you can lift one time. If the heaviest weight you can lift is 10 lbs. then you will have trouble carrying a 20 lb. sack of fertilizer to the front yard, bringing in the bag of groceries the sacker put all your heavy items in, or picking up your 18 lb. grandchild without injuring yourself. The American College of Sports Medicine recommends 2-3 sessions of strength training every week. Failure to work on strength results in loss of muscle mass and increasing weakness.

Muscular endurance. This is the ability to lift a weight repeatedly or to hold that weight up for a sustained period of time. You need muscular endurance to continue using tools until your project is completed, to spread mulch in the flower beds, and to carry a child through the parking lot. To work on muscular endurance you lift lighter weights 12-20 repetitions; to work on muscular strength you lift heavier weights 2-10 repetitions. The good news is that improving strength also improves endurance and vice versa.

Flexibility. This is the ability of your arms and legs to move at the joints through a complete range of motion. Flexibility reduces the risk of injury. A decrease in flexibility makes it harder to move and perform the activities of daily living. To maintain flexibility, joints must be taken through their full range of motion on a regular basis. The American College of Sports Medicine recommends stretching 2-3 days each week. Hold each stretch 10-30 seconds, then repeat each stretch 2-4 times, accumulating 60 seconds per stretch. The best time to stretch is immediately following an exercise program.

Body composition. This refers to your percentage of fat as compared to lean tissue, that is bones, muscles and organs. You need an adequate amount of muscle to increase your stamina and boost metabolism. Too high a percentage of fat increases your risk of disease. Exercise can help improve body composition.

Skill related components of physical fitness. Agility is the ability to change body positioning in space quickly and accurately. You need agility when your cat or dog plops down in front of you and you have to suddenly maneuver to avoid tripping over him or stepping on his tail. Balance is the ability to maintain equilibrium both while standing and while moving. Poor balance leads to falls. Coordination allows you to use your vision and hearing in conjunction with your muscles to perform motor tasks. That’s why it is important to get your vision and hearing tested regularly. Power is the ability to react quickly when something happens. Improvements in agility, balance, coordination and power come with practice and repetition. In a water fitness class you are practicing these skills when you move from one exercise to another, change tempo from slower to faster, change direction of travel, perform one-footed moves and various other exercises.

Information for this article comes from AEA’s Aquatic Fitness Professional Manual (2018) and from the American College of Sports Medicine’s website https://www.ascm.org Water fitness exercises for all the components of physical fitness can be found in my books Water Fitness Progressions and Water Fitness Lesson Plans and Choreography.

How to Fall Safely

1

More than one out of every four people 65 or older falls each year. One out of five falls causes a serious injury such as broken bones or a head injury. Over 800,000 patients a year are hospitalized because of a fall injury. Each year at least 300,000 older people are hospitalized for hip fractures. These statistics from the Centers for Disease Control and Prevention are a concern for many of my water exercise class participants and for me. When I came across some articles on How to Fall Safely, I decided the information was worth passing on.

I found articles from several sources, including AARP, physical therapist blogs and wikiHow. The pictures in this Blog post come from wikiHow. The co-author of the post was Chris M. Matsko, MD.

Protect your head. Head injuries can be very serious. Make sure you prioritize protecting your head. Tuck your chin down to lower your head. If falling face first turn your head to the side. Use your arms for additional protection. Put them in front of your head if falling forwards or behind your head if falling backwards.

Turn as you fall. If you are falling either straight forward or straight backwards, try to turn your body so you land on your side. This reduces the risk of injuring your head, face, arms or back.

Keep arms and legs bent. It may be tempting to try and catch yourself with your arms. However, landing with your arms straight out can break your wrists and/or your arms.

Stay loose. Tensing up increases the chance of sustaining an injury. The tense parts of the body are more likely to break. Try breathing out as you fall to help keep your body relaxed.

Spread out the force of the fall. A big part of falling safely is to spread out the force of the impact over a large area of your body. This reduces the risk of a serious injury to a single part of the body.

Another suggestion is to roll out of the fall. This is difficult to do unless you have practiced beforehand. If you wish to learn the technique, you can ask a physical therapist to show you how, or practice falling and rolling in a gym with padded and cushioned floors.

Just as important as knowing how to fall is taking steps to prevent falls in the first place. Wear shoes with slip resistant soles. Pay attention when you walk. Be aware of uneven areas on the ground, curbs and stairs. Hold the hand rail when taking stairs. In the home, close drawers after you are done with them. Don’t leave cords in walkways. Keep the area well lit. Use non-slip bath mats. Remove small throw rugs.

Another way to reduce your risk of falling is to improve your strength and balance with exercise. The pool is the perfect place to work on both strength and balance. Because the water’s buoyancy and resistance helps support the body, exercises can be done without fear of falling. Options include the following:

Gait training. Gait training is walking practice. The goal is to lengthen the stride and improve confidence while walking.


Core Strength Training. Core strength training is training for the postural muscles of the trunk. This includes the Trapezius and Rhomboids, the Latissimus dorsi and the Erector spinae. Exercises to try are rowing, bowstring pull, and lat pull-down using the water’s resistance or drag equipment. Walking backward strengthens the Erector spinae.

Deep-Water Exercise. Deep-water exercise is performed, while wearing a flotation device, in water in which a person can remain vertical without the feet touching the floor. Exercisers must aggressively engage the stabilizing muscles of the core to remain upright.

Balance Challenges. Balance challenges are exercises performed with a narrow base of support, such as the feet together, one foot in front of the other, or standing on one foot. Slow movements are more challenging than fast ones.

Falling is scary, but learning how to fall and taking steps to prevent falls in the first place are things we can all do now to reduce the risk.

Holiday Ideas for Your Class

14

swimming-santa-claus

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 www.yesfitnessmusic.com.

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

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

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 H20_mail@h2owear.com 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!
