Aquatic Exercise For Osteoporosis

Exercise / September 30, 2016

water exercise for osteoporosis

As part of the customer care team, I get to speak to you, our customers, everyday.

Each conversation gives me more insight on the difficulties of having osteoporosis. And what it’s like living with the fear of fracture. So I also always recommend a few important lifestyles changes. This includes a daily protein intake of 60 grams and exercising at least 30 minutes a day in addition to our supplements. (You can read more about the role of protein for bone health here).

I have spoken to many customers who suffered compression fractures and limited mobility. They remind me that not everyone can walk or do weight-bearing exercises. Or that they are afraid of losing balance, falling and breaking a hip. And I can see why. In all, 80–90% of hip fractures in older adults are related to falls – and women have a ⅙ risk of having a hip fracture in their life.¹

All studies show that exercise decreases the risk of fracture in adults with osteoporosis. They do this by maintaining or improving bone density and improving balance. And therefore leading to a decreased risk of falling.²⁻³

So this pushed me to do some research on alternative exercises that I can recommend to all. I know how important exercise is for your bones and health and I’m passionate about providing everyone with a solution.

Hydrotherapy and Water Exercise for Osteoporosis

Before recommending this to you for bone building, I wanted to investigate if water exercises or hydrotherapy is beneficial for bone health. And also compare the benefits to regular exercises on land.

Usually, weight bearing exercise is recommended for increasing bone density. In weight bearing exercises, you are supporting your own body weight through your feet and legs against gravity. So that includes jogging, running, walking and jumping for example. They increase bone density by having the muscle pull on the bone through impact on the ground and from carrying your body weight. The National Osteoporosis Society mentions that swimming is not weight-bearing. And that it does not affect bone density.³ That’s because there’s less gravity in an aquatic environment.

So What is Aquatic Exercise and Can It Help Your Bones?

Aquatic exercise is “vertical exercise in the water with the participant submerged to chest or shoulder depth”.⁴ I’ve included some examples at the end of this post for you to try. But for now let’s look at what are the benefits!

The Benefits of Aquatic Exercise:

  • Decreased stress on weight-bearing joints due to the buoyancy of the water
  • Increased mobility due to diminished gravitational pull
  • The ability to use varying levels of resistance for strengthening
  • Increased sensory stimulation in brain.

So like I mentioned aquatic exercise is not usually recommended for individuals with osteoporosis because there’s less gravity. But it is recommended for individuals with more severe osteoporosis to improve function and balance. That’s because of the extra benefits from the support and comfort of the water.

Balance is important in reducing the risk of falling and thus the risk of fracture. A 2008 study compared aquatic versus land exercise on balance and quality of life in women with osteoporosis. The study found significant improvements in women’s balance in both land and water exercise. So if you have difficulty exercising on land (or simply don’t enjoy it) aquatic exercise is a good alternative for you!  

Another study from 2008 examined if aquatic exercise can improve bone density. They found that the exercise group was able to maintain and slightly improve their bone density compared to the control group.⁵ They were doing 3 hours of aquatic exercise for 7 months.

So not only can water exercises increase balance and posture but it can also slightly increase bone density. Not as much as running or other weight bearing exercises but still very significant!

There are still few clinical studies done to measure the bone building effect of water exercises. But all show increase in balance, muscle development and some increases in bone density. Many people report decreased back pain and improved back strength and posture too!

Unfortunately water exercise classes and especially hydrotherapy is not available everywhere. But you can do a few exercises at your local pool with an instructor or with friends. If you have hydrotherapy or aquatic classes close to you, I encourage you to take advantage of it. Plus it can be a lot of fun! And when you enjoy exercising it doesn’t feel like you’re exercising. You know what I mean!

Joining an aquatic exercise class for seniors can be terrific fun! Watch this short video from the ABC channel featuring Dr Jane Katz:

So do you have difficulty doing regular weight bearing exercises or just want to try something new? Here are a few examples of water exercises.

Water Exercises

You could start by moving slowly around in the water, then try the exercises described below. Water spas or jacuzzis provide extra warmth and a soothing massage (but maybe not the super hot ones). Be careful going in the pool as it may be slippery, so never go alone. Stand with the water up to your chest. If this makes you feel short of breath, move to shallower water. Remember do not push exercises to the extent that they are painful.

Also make sure that your movements are comfortable and this way you will not overdo them.

  • Stand with your feet hip width apart and rest your arms on the surface of the water. Then gently turn your body to the right, swinging your left arm in front of you and your right arm behind you. Keep your elbows straight and in the water throughout. Repeat in the other direction.
  • Stand holding on to the side of the pool. Bend one hip and knee up in front of you, standing tall and keeping your back straight. Then stretch your leg out behind you, keeping your knee straight. Repeat with the other leg.
  • Try taking long steps in the water (forwards and then sideways).
  • Note:  If you want to try hydrotherapy, make sure your therapist is an accredited physical therapist in your country.

So if you are looking to increase your bone density but find it painful to exercise on land, I recommend the following:

Try water exercises along with AlgaeCal Plus and Strontium Boost! And if you haven’t already, I recommend Triple Power Fish Oil. It will help reduce inflammation that is causing bone loss, plus it aids with swelling and pain in your joints.

The 2008 study…. 3 hours of aquatic exercise for 7 months? Please clarify…is that per day? per week?


Hi Maggie,

To clarify, the study says that, “[these] women trained for seven months for three one-hour sessions per week.”

I wonder if the breaststroke helps to increase bone density in the spine. My bone density has improved 10 percent in the spine in one year. I love swimming and swam nearly every other day feeling a little guilty not doing anything for my bone density wth swimming.
