Sample Size

Posted by jonwilliam on 25 Oct 2010 at 02:11 GMT

Sample size is too low. The authors should do apower analsysi or atleast write hwo they came with the current sample size.

Even if the results are significant, the small sample size makes it a suspect.

Jon: As our email exchange will attest your concern here is misplaced. Adding more subjects (legs) will only reduce P and make any significant finding MORE significant (i.e., P will decline). Our approach, due to the cost of these studies, is to use the smallest sample size possible to see a significant effect. So, the cost of this type of study is prohibitive if we test too many subjects. Suffice to say that this is a proof-of-principle study and we will follow this up. Your suspicions will be put to rest; this method of training works to increase strength and hypertrophy!
