It is puzzling to me when coaches and exercise professionals say things like "I do not care about studies. I am interested in the real world" or words to that effect. I understand the perspective (I think) and many studies can seem pretty obscure, but it misses the point.
Exercise research is designed to lead to "real world" benefit. The research may affirm something discovered by an exercise professional, or the research may help clarify a disputed issue. It also may offer a completely new idea not yet considered by exercise professionals. In any case, the research should advance... read more
One point of exercise research is to determine the "mechanism" behind a given outcome. When the mechanism for a positive outcome is determined, duplication becomes possible.
A recent Norway study attempted to determine the mechanism for "muscle memory" and came up with some interesting findings.
This study was done on mice so we need to place an asterisk beside it. Animal studies do not prove the same thing occurs in humans, but they can lead to later successful human studies.
The study found resistance training increases muscle cell nuclei, and this increase may last for a lifetime... read more
A 2008 review showed the potential of resistance training to help running performance.
Yamamoto reviewed the highest quality research involving highly competitive runners. Four of the studies involved explosive resistance training and one study involved strength training only.
Four of the five studies showed running economy improves from resistance training. Running economy is one of the "Big Three" variables for running performance (along with VO2 Max and Lactate Threshold).
Two of the studies showed actual time improvements from the resistance programs.
Yamamoto concludes plyometric training can improve running economy and running performance.

"Any workout is better than no workout"
"Just go the gym and get started! You will figure out what to do."
"Lifting weights is healthy."
While these statements certainly contain great bits of truth, they do not provide the entire picture about the dangers of inappropriate resistance training.
A recent paper (Kolber 2010) highlighted the real risk of resistance training on the shoulder.
One study analyzing pectoral ruptures found 29/112 of the ruptures involved the bench press; The bench press has been associated with distal clavicle osteolysis (DCO). DCO is characterized by a/c joint... read more
