Figure 1. Building a bigger engine versus a better engine: A comparison between impairment-based and task-specific motor learning exercise programs.

Figure 1

We relate differences in the exercise programs to differences in building an engine for maximum versus optimal performance. The impairment-based program results in greater physiological capacity in body systems that can be used for walking (i.e. maximum performance). The motor learning program results in a more efficient use of physiological capacity in body systems for walking (i.e. optimal performance).
