Motor Performance
Figure Legend
Figure 2 concerns the principles of kinematic and submovement parsing, illustrating young and older adult position, velocity, and acceleration profiles. Each of the six panels covers specific profiles: A) Young adults' positional data; B) Young adults' velocity profile, including acceleration and deceleration phases/times; C) Young adults' acceleration profiles, including primary and secondary submovement parsing; D) Older adults' positional data; E) Older adults' velocity profile, including acceleration and deceleration phases/times; F) Older adults' acceleration profiles, including primary and secondary submovement parsing.
