OK, were back, and I was indeed able to find some good information on swimming, so MUCH information that Im going to actually split it into two parts, one presented as a more factual 'this is the way it is' and the other with some of my FAVORITE type of evidence, 'anecdotal', as seen through the eyes of an OI patient who is actually devoting their life's work to helping the rest of us, get or stuff together!

     Now in part two comes a write up from a member of the OI community who is also a personal trainer and is looking for alternative ways to HELP everyone, OI or not, even if hey only start with explaining the what who and WHY of it all!

     The Benefits of Swimming for Osteogenesis Imperfecta Patients

     As someone born with brittle bone disease, finding the right forms of physical activity has always been a challenge. Most sports and intense exercises come with too high a risk of fractures and injury. However, swimming has proven to be an extremely suitable option for those with Osteogenesis Imperfecta (OI). The properties of water provide an ideal environment to improve strength, mobility, and cardiovascular health.

     I was introduced to swimming from a young age, as doctors advised it was one of the safest sports for me to participate in. Now decades later, I continue to swim regularly for both physical and mental well-being. The flexibility swimming offers in terms of intensity and impact modulation makes it accessible for OI patients of all ages and abilities.


Low-Impact Cardiovascular Exercise


     One of the primary benefits of swimming for OI patients is the ability to raise the heart rate and sustain aerobic activity without the high impact of running or other upright exercises. The water supports and cushions the body to take pressure off the bones and joints. This makes swimming a gentle form of cardiovascular training to improve stamina.

     The resistance provided by moving through water also naturally increases the intensity of exercise. Yet swimming remains low-impact even when pushing oneself. Those with OI must often avoid high-impact activities like running, which can lead to sedentary lifestyles and poor cardiovascular health. Swimming offers a solution.

     Another advantage is swimming engages the entire body. All the major muscle groups are worked as the arms and legs propel you through the water. This non-weight-bearing exercise improves conditioning without taxing fragile bones. The range of swimming strokes also helps develop balanced strength and mobility.


Building Bone Density


     While swimming is gentle on bones, research indicates it may also help build bone density in those with OI when practiced consistently. The combination of resistance training and weightless environment encourages the bones to gradually strengthen over time. One study found young OI patients who swam 30-40 minutes twice a week for a year gained significant bone mass.

     Though swimming does not involve weight-bearing load like running, the water resistance provides some osteogenic (bone building) benefits. The muscle strengthening that occurs also helps support bone health. Of course, these density gains will likely be modest compared to land-based weight-bearing exercises, due to the lack of gravity. However, any increase with minimal fracture risk is worthwhile.


Improving Joint Stability


      In addition to strengthening bones, swimming enhances the muscles surrounding joints. This added muscular support improves stability in the areas prone to dislocation from frequent fractures. The joints also gain a wider range of motion as the ligaments and tendons are gently stretched.

For many with OI, movements like reaching, twisting, and bending can make joints unstable. The buoyancy of water lets one move freely through positions that might cause subluxations on land. With supervision, a hydrotherapy program can safely improve joint mobility and control.

     Swimming strokes emphasize body alignment and smooth motions. Practicing proper technique reduces joint strain and engages the appropriate stabilizing muscles. The lightweight yet challenging environment facilitates gaining strength in a controlled manner.


Soothing Effects on Pain


     While exercise in water does not eliminate fractures or associated chronic pain, many with OI find swimming provides some soothing effects. The sensation of being weightless in a warm pool can temporarily reduce aches and discomfort. Even gentle water exercises engage muscles to increase blood flow and naturally elevate mood through endorphin release.

     Buoyancy reduces the strain placed on bones and joints during movement. For some, this temporary relief enables exercise that might otherwise be too painful. The peace of mind from knowing falls or collisions are unlikely in the pool can also help OI patients relax tense muscles and loosen stiff joints.


Mental and Emotional Benefits


     Beyond physical rewards, swimming has additional mental health value for those managing a lifelong bone condition. The independence and normalcy of being able to move with ease through water can be incredibly empowering. It provides a sense of capability often missing on land where you feel fragile.

     Exercising in a group swimming class also creates community. Surrounded by others, differences become irrelevant. Supportive peers can inspire you to push beyond what seems possible. At the same time, individual lap swimming offers quiet solitude for contemplation and stress relief. The meditative nature enhances mental clarity.

     The pride of tracking improvements in speed or endurance over time is also motivating. Small goals like increasing laps gradually build confidence. Success comes from consistency more than innate talent. For many, the therapeutic nature of swimming makes it as much a mental exercise as a physical one.


Precautions and Safe Swimming


     While generally recommended, swimming does require some safety precautions for OI patients. Consult a doctor before starting a swimming program to discuss any joint instability, respiratory issues, or other concerns. Avoid overexerting yourself and focus on proper form.

     Classes for disabled or special needs swimmers provide qualified instruction. Work at your own pace. Use flotation devices as needed for stability or rest. Avoid diving boards, slides, or rough play that could lead to injury. Listen to your body's limitations on any given day.
