A Study of Racket Weight Adaptation in Advanced and Beginner Badminton Players

Figure 2

Muscle synergy characteristics of advanced and beginner players during jump smash. The vertical axis of motor modules is the normalised per-muscle contribution amplitude (horizontal lines of 0.25, 0.50, 0.75, and 1, respectively), and the scatter indicates the distribution of the trials; the vertical axis of motor primitives is the normalised motor module activation strength (the shaded squares represent significant differences) (a) advanced players; (b) beginner players (left: 3U; right: 5U).
