31P-MR investigations of training effects on resting state concentration of phosphor metabolites in the M. gastrocnemius

Fig. 4: P-MR spectra of the M. gastrocnemius (medial head) prior (blue) and after (green) a four-week training. Spectra are normalized by the ATP signal intensity. The intensity of the PCr signal is clearly decreased after training. Fig. 2: P-MR spectra of the medial (blue) and lateral (green) M. gastrocnemius and transverse T1-weighted images to illustrate the position of the coil sensitivity range for both positions. Spectra are normalized by the ATP signal intensity. The spectrum of the medial muscle shows higher PCr and lower Pi intensities. lateralis medialis
