Figure 2.

Panel A: A stacked plot of 300 ³¹P spectra after spectral improvement by Fourier thresholding processing. Panels B and C: Temporal plots of phosphocreatine (PCr) areas during the recovery of subject 2 from lifting exercise and the result of a monoexponential fit (green line), which yields the PCr recovery rate. PCr recovery time decreased from 48.5 to 22.5 seconds after 12 weeks of Tai Chi training. α, β, γ‐ATP = adenosine triphosphate resonances (alpha, beta, and gamma); Pi = inorganic phosphate; ppm = parts per million; τ = recovery time constant.
