Effects of Walking on the Beach

Is walking on the beach bad for my knees?
The answer to this question may be more complicated than you think. Walking on the beach CAN be bad for your knees, especially in the case of symptomatic knees. If you are already experiencing knee pain, have had a recent surgery, or are walking with a limp, then walking on the beach is not recommended. This is due to the fact that the beach sand provides an unpredictable and uneven walking surface. This can place increased stresses, strains, and loading on your joints. Walking in the softer sand requires increased energy expenditure, forcing you to work harder compared to walking on an even, firm surface. The foot will sink slightly into the sand. This will provide the least amount of stability, which forces you to use muscles throughout your legs more. Also, in the event that you already have pain and swelling in your knee, the receptors within the joint that control balance, and make changes for the joint position on uneven surfaces, get shut down. This also shuts down the smaller stabilizing muscles around your knee thus, potentially, increasing your risk for further injury.
Walking on the firmer sand near the water is likely a better choice but that also doesn’t come without risk. First, you must make it through the softer sand to get there. (Don’t forget you have to get back as well.) Near the shoreline, there is a slight slope to the firm sand. This can be compared to walking on a sloped road or curb. This can provide additional stresses to the entire kinetic chain from the foot up to the knee, hip, and back. You may not notice it at the time you are walking, but increased symptoms of pain and swelling may follow. This can result in setting you back even further.
Benefits of Walking on the Beach
Walking or running on the beach can be fine for people without knee symptoms. It can be a great way to exercise, relieve stress, fight certain diseases, improve strength and increase energy. If you are not used to walking or running on the beach it is advised that you start very slowly and work your way up, even if you are feeling fine throughout your walk or run. Some believe you should limit yourself to 10 minutes for beginners to see how your body responds before gradually progressing. To reduce the risk of an injury, prepare for walking on the sand with the right strengthening exercises. Also be sure to consistently vary the surfaces you walk or run on.
If you have questions about walking or running on the beach is right for you, be sure to consult with your physician or physical therapist.
