The relationship between plyometrics training, upper-body isometric strength, stick velocity and puck velocity for the slap shot was examined for male university hockey players over 10 weeks. Twenty-one volunteers were divided into either an experimental or a control group. The experimental (plyometrics) group was pre- and post-tested for upper-body isometric strength and slap shot puck and stick velocity. Results showed that puck velocity increased (p<0.05) from pre- to post-testing, with no differences between groups. Stick velocity increased 13% (p<0.05) for the experimental group at post-testing. No significant correlations were found between isometric strength, stick velocity and puck velocity; however, a positive correlation was found between changes in stick velocity (off-ice) and changes in puck velocity (on-ice). Results suggest that plyometrics may improve ballistic coordination between the upper and lower limbs in as little as 6 ± 2 sessions.
