Figure 4. Smad2 phosphorylation following resistance exercise.
The degree of Smad2 phosphorylation was determined in an attempt to measure myostatin signaling in vivo at the end of a 20 min bout of high force lengthening contractions and then 0.5, 3, 6, 18, and 48 hours later. Smad2 phosphorylation was unchanged at any time point following resistance exercise (n = 4).
