the Fine Print on
Exercise Equipment
Understanding risk management is essential for all fitness professionals, and it requires more than simply having clients complete a health questionnaire. In today’s training environment, clients are more overweight, deconditioned and have more musculoskeletal issues than ever before. Simultaneously, the use of high intensity exercise along with various forms of equipment that are designed to make exercises more challenging have become commonplace, increasing the risk for muscle or joint injury or worse. Failure to properly progress clients or incorporating circus-like activities that have limited return to the individual can be costly decisions for any fitness professional.
For example, not too long ago a woman was awarded $1 million in a lawsuit against a Personal Trainer and gym in Texas for improper use of exercise equipment. The woman was performing standing exercises on the flat side of a BOSU ball when she fell and broke both wrists. The makers of BOSU were exonerated because they have a warning label on the flat side of the BOSU that firmly states "DO NOT STAND ON THIS SIDE." Have you ever read the bottom of your BOSU?
We encourage you to review your personal risk management system so that you can avoid unfortunate situations such as this. Educate your staff on safe and proper use of exercise equipment. Don’t be swayed by the latest Youtube phenomenon. Make sure that your equipment is in proper working order. Check your elastic tubing and stability balls for surface damage frequently. These are just a few steps you can take to make sure you’re not the next headline.

Quick Weight Loss = Lasting Weight Loss?
For overweight and obese individuals losing weight can have a profound impact on both quality and quantity of life. Once that fact is internalized most people can't take the weight off fast enough. Weight loss experts, however, will commonly advise a more gradual approach that creates a loss of 1 to 3 pounds per week, depending on baseline weight. This philosophy is based on previous research and experience that suggests using more practical and sustainable solutions that are also less likely to negatively affect hormones or metabolism.
Unfortunately, popular diets and media are creating higher expectations for overweight Americans that differ from this recommendation. These expectations are creating a challenge for weight loss professionals, for if the expectations for fast weight loss are not met motivation could be lost and dropout is likely. So, the question remains... what is the optimal rate of weight loss that promotes better health quickly and is sustainable? A recent study may be set to challenge professional beliefs after finding that faster weight loss might actually be more productive.
Researchers from the University of Florida evaluated the effects of varying amounts of caloric restriction on total weight loss over 6 months and maintenance of weight lost for 1 year thereafter. More than 250 obese middle-aged women were encouraged to consume a diet designed to facilitate either a 1/2 pound, 1/2 to 1 1/2 pound, or a 1 1/2 pound weekly weight loss. After 6 months, the groups had lost on average nearly 11 pounds, 20 pounds, and 30 pounds, respectively. Follow-up was completed 1 year after the initial 6-month weight loss period. Interestingly, all groups gained back approximately the same amount of weight over the course of the follow-up year.
In this study, it appears to have been more valuable to have lost a greater amount of total weight quickly instead of attempting to lose weight more gradually. It is important to realize, however, that popular media is leading people to believe that 5 to 7 pounds of weekly weight loss is desirable. Although this study indicates that there might be a benefit to faster weight loss researchers remained within the advisable range for rate of weight loss.

Does Taste Affect Dietary Compliance?
Low calorie, pre-packaged frozen meals are a convenient resource for many dieters who may be too busy to prepare food regularly. Unfortunately, if you're someone who relies on those meals regularly your interest may be more likely to wither and the success of your diet may be compromised. In a recent study, researchers found that people lost their taste for diet-brand frozen meals over time compared to equal higher-calorie options.
Thirty-six adults volunteered to eat one of two prepackaged meals over 5 consecutive days for lunch. The first group received a meal consisting of 567 calories of Spaghetti Bolognese, while the second group received the "diet" meal that contained just 374 calories. Researchers questioned the participants to determine their satisfaction with taste and satiation after each feeding.
Interestingly, although both meals were rated similar for taste at first, those eating the diet-brand rated the food 30% less favorably by the end of the week. Nonetheless, all reported feeling full throughout the entire week despite having experienced a decline in flavor ratings. Although purpose may override sensation for many dieters, the researchers believe this finding could be a reason for poor compliance among people who rely on diet-brand foods.
There are definitely many limitations to this study; however, this finding may indicate a need for greater variety in food selection among dieters. Moreover, frozen food options may not be the best solution for long-term weight management regardless of practicality.

Weight Gain Likely Post-Knee Replacement
Currently, more than 250, 000 Americans undergo knee replacement surgery each year. The vast majority of cases are a consequence of severe knee osteoarthritis, which causes significant pain, stiffness and often leads to a sedentary lifestyle and associated weight gain. It is generally assumed that individuals with severe knee osteoarthritis who have been physically limited would resume an active lifestyle and lose weight following total knee arthroscopy. Unfortunately, a recent study suggests otherwise.
Researchers at the University of Delaware evaluated body weight, perceptions of function, and quadriceps strength in 106 people who underwent single joint knee replacement, and 31 controls who exhibited no knee pain at baseline and 2 years post-operative. Participants who underwent surgery received post-surgical Physical Therapy.
Interestingly, over 2/3 of those who underwent knee arthroscopy gained an average of 14 pounds in the 2-year period, while 1/3 of participants lost 4 pounds on average. Comparatively, the control group's weights were unchanged. Additionally, the quadriceps strength in the group that gained weight decreased during the study, but not in the group that lost weight.
These finding were a complete surprise to the researchers as the consequences of weight gain post-knee replacement can be costly. Additional body weight can result in faster progression of osteoarthritis in the non-prosthetic knee joint, and thus a second knee replacement. Moreover, it can result in further de-conditioning and increase risk for cardiovascular or metabolic disease. Consequently, the researchers are advocating for greater education on nutrition and encouraging physical activity following knee replacement to prevent weight gain.
