Noninvasive Monitoring of Training Induced Muscle Adaptation with -MRS: Fibre Type Shifts Correlate with Metabolic Changes
Figure 1
Biopsy samples of the gastrocnemius muscle showing examples for fibre type classification utilizing different staining methods—(a) ATPase enzymohistochemistry preincubation at pH 4.6 (classified into slow-twitch type I and fast-twitch type IIa/IIb), (b) MHCfast immunohistochemistry, (c) MHCslow immunohistochemistry (classified into slow-twitch type I and fast-twitch type II with MHC staining).
