Heat treatment boosts anabolic effect of strength training
We're not quite sure how strength athletes can apply the principle that Japanese sports scientists have written about in the Journal of Physiological Sciences. The equipment the scientists used to enhance post-strength training anabolic processes in muscles is not yet available. At least, not yet where ordinary mortals do their shopping. Or might infrared lamps be an alternative?
Anabolic heat
Study
On one occasion the men just did the leg training. [RE] On the other occasion the researchers placed a microwave therapy unit 15 cm above the subject's leg. [HRE] They used the Microtizer MT-SDi made by Minato Medical. This was used to warm the subjects' muscles, starting twenty minutes before the training session began and continued during the session. The muscle temperature was 8.9 degrees Celsius warmer than normal. The procedure is described in a letter published in the Journal of Sports Science and Medicine in 2008. [JSSM 2008 (7) 191-3.]
Results
The heat treatment had no effect on AMPK, S6K1, eEF2, ERK1/2 or p38.
The researchers speculate that the heat treatment activates the key anabolic regulator molecule Akt, which starts a cascade of reactions in the muscle cell.
