Objectives: To determine the impact of between limb asymmetries in hop performance on change of direction speed (CODS). Design and Methods: Twenty-two multisport collegiate athletes (mean ± SD; age: 21.8 ± 3.4 years, height: 178.1 ± 6.7 cm, mass: 73.5 ± 7.1kg) performed three single and triple horizontal hops for distance per limb, followed by three modified 505 and 90 ̊cut CODS trials each side to establish imbalances between right and left, and dominant (D) and non-dominant (ND) limbs. Limb dominance was defined as the limb that produced the furthest hop or faster CODS performance. Results: Paired sample t-tests revealed no significant differences in hop performance and CODS performance between right and left limbs (p > 0.05, g ≤ 0.11), however, significant differences were observed when comparing D and ND limbs (p < 0.001, g = 0.46-0.61). No significant correlations were observed between hop imbalance and CODS performance (p > 0.05, r ≤ 0.35). Low agreements (32-55%) were demonstrated between like for like identifications of asymmetry for CODS and hop performance. Conclusions: Imbalances in hop and CODS were present; however, greater hop imbalances were not detrimental to CODS. Furthermore, the D limb for hopping did not necessarily correspond to faster performance from that limb during 180 ̊ turns and 90 ̊ cuts (plant foot). Collegiate male multi-sport athletes with imbalances within the range reported within this study (≤ 15%) should not experience associated CODS detriments. (Journal of Trainology 2017;6:35-41)

Asymmetries in single and triple hop are not detrimental to change of direction speed
