The US Consumer Product Safety Commission has had 47 complaints from people that have received fractures or bruises from using their stability balls. Due to these complaints, the US Consumer Product Safety Commission has sent out a voluntary recall of over 3,000,000 stability balls. These stability balls were made by EB Brands and were under the brand names of Bally Total Fitness, Everlast, Valeo and Body Fit Fitness Balls. The Consumer Product Safety Division of Health Canada has not made any warning or voluntary recall of these common fitness brands as seen at Winners and Zellers. Here are four dangers that every personal trainer needs to know when training their clients on a stability ball:
Keep it Under 330 Pounds ? Many stability balls will only hold 330 lbs of force. When you train your client with exercises that involve bouncing on the stability ball, it creates more force than most stability balls can handle. The increased force, increases the risk of the stability ball bursting. When training your client on the stability ball make sure they do not bounce; in order to get maximum benefit from the exercise and decrease the risk of the ball bursting and injuring your client.
Don?t Use Weights ? Many stability balls do not recommend using additional weight. For example; dumbbells or medicine balls. Additional weight increases the force on the ball and increase the risk of it bursting. When training your client use the stability ball for bodyweight exercises like squats and ab crunches.
Fill it to the Recommended Height ? The main reason why stability balls burst on people is they are over inflated. People will fill them up. They will use them for a while and the rubber will stretch. Since the rubber has stretched, the ball becomes flat or softer, so they pump it up with more air so it feels firmer. This thins out the rubber of the ball and leads to greater risk of popping. Pump up the stability ball once to the recommended height using a tape measure and wall. If you like a firmer stability ball that will hold its shape, ask your local fitness equipment store for options.
Make Sure the Temperature is Right ? Check to see what temperature the manufacturer recommends the ball be inflated at. Many times they will recommend pumping up your stability ball in an environment that is between 32? C and 18? C. This is because stability balls shrink and expand at different temperatures. Check what is recommended and fill up the stability ball at those temperatures in order to be safe.
These are four tips on the dangers that every fitness professional needs to know when training their client with a stability ball. In order to be safe and get maximum results for your client, avoid exercises that involve a lot of bouncing, don?t use weights on a stability ball, fill the stability ball to the recommended height, and make sure you fill your stability ball in the right temperature.
