Your Daily News On Muscle Injury, Recovery and Performance
Bodybuilding or power lifting workout. Which gives the most muscle hypertrophy?
There's a lot of people that want to get more muscle for beach season. Most trainers and health professionals know that there are a lot of paths to that road. Should you use more of a bodybuilding type of program (higher reps and less rest in between sets) or a power lifting type of program?
Results are in. In a new study, both gave the same amount of muscle hypertrophy. However, the power lifting group led to greater strength gains. This study was done on the biceps muscle.
There you have it. Do more power lifting type of exercises. This isn't new. However, one word of caution before you begin lifting weights that your body can't carry. Look at your physical condition in the beginning. Get your muscle assessment done by a competent trainer or health professional.
It would have also been interesting if the study looked at nutrition. Nutrition is probably the biggest factor that comes into play here. What do you think? Do you see the biggest gains by changing up nutrition or changing up an exercise program?
Can we substitute pain ratings from patients for objective pressure pain threshold measurements? Not so fast....
Health professionals are always on the look out for objective measures to assess improvement in treatment. Checking out changes in pressure pain threshold is one test that we may all rely upon. However, do we need to throw out the simple pain rating scale for this? New study says no.
The recent study basically came to the conclusion, after using pooled data from 7 randomized controlled trials, that there was no correlation with pressure pain threshold measurements and pain intensity. Looks like those simple pain ratings shouldn't be discarded before more research is done on pressure pain thresholds.
More support for using both performance tests AND self reported questionnaires
Patient walks in with lower extremity osteoarthritis. For you health professionals, do you rely on subjective questionnaires and performance tests? Did you know that each measures a different aspect of improvement?
A great new study looked at whether self report and performance based testing captures the same aspects of disability. They found that they didn't capture the same aspects of disability and are influenced by different types of underlying impairments. Specifically, greater pain predicted lower HOS (Hip Outcome Survey) scores, but hip strength had no effect. Just another research study that shows the importance of using multiple clinical measures, putting them together, and coming up with a logical conclusion. I guess there IS room for critical thinking in health care!
Can you expect more back pain as an adult if you have idiopathic scoliosis?
When we do an assessment on individuals, its easy to assess for static posture differences and tell someone that its going to cause them problems later on, if they didn't come into your office for that problem that day. Question is, do any of these findings actually correlate with pain?
A new study tried to answer that question for adults with idiopathic scoliosis. They found that adults with scoliosis had a 64% prevalence of back problems compared to 29% for those without. The findings also showed that treatment, gender and juvenile or adolescent onset had nothing to do with the prevalence.
If you find an adult patient with idiopathic scoliosis, you may want to educate them on beginning a good strengthening / stretching / muscle balancing program. They will need it.
