Figures

Figure 1
Figure 1
Group mean (n = 6) phosphocreatine breakdown (PCr) and deoxygenated myoglobin increase (deoxy-Mb) across the rest to exercise transition for moderate (60% of the work rate associated with isolated muscle aerobic capacity) and heavy (80% peak work rate) intensity plantar flexion exercise. Data are normalized to the percentage of the end-exercise values. The figure is redrawn from Figure 1 in Richardson et al. (6) to illustrate the difference in the PCr and deoxy-Mb kinetics during first minute of contractions. Error bars are omitted for clarity [see Richardson et al. (6)].
