Strength training plus VertiMax® training with no upper extremity resistance training. Group VNA (n = 12) performed strength training and VertiMax® training. The VertiMax® training followed the manufacturer’s suggested basic training program, as shown in Table 1. Cord resistances were increased one-half of a band at weeks 3 and 5. These lesser resistances were selected as the VertiMax® was a novel training modality for the subjects; thus, the researchers did not want to introduce too large of a training stimulus via added resistance. Cord resistances were returned to beginning levels at week 6. The manufacturer suggests a cord intensity that will not significantly alter jumping and landing kinematics. On the resistance cords are marker bands
