Dann, E, Quinn, S, Russell, M, Kilduff, LP, Turner, AN, and Hills, SP. Alternate leg bounding acutely improves change-of-direction performance in women's team sports players irrespective of ground type. J Strength Cond Res 37(6): 1199-1203, 2023-This study aimed to assess whether body mass only alternate leg bounding performed post-warm-up on grass or a hard surface acutely improves preplanned change-of-direction performance in women's team sports players relative to a control condition and, if so, profile the time course of such changes. On 3 occasions, 14 amateur women's team sports players performed 20 m preplanned change-of-direction ("Pro-Agility") tests at 4, 8, and 12 minutes after interventions. Interventions were implemented immediately after a standardized warm-up and consisted of 3 sets of 10 repetitions of alternate leg bounding (5 ground contacts per limb) on a hard indoor surface (HARD) or natural grass (GRASS), or a control condition involving approximately 75 seconds of continuous walking with no bounding (CON). Performance was similar between conditions at 4-minutes postintervention. Performance at 8 minutes was greater in HARD (2.9%, p = 0.015) and GRASS (3.8%, p = 0.029) relative to CON, whereas GRASS also exceeded CON at 12 minute post-bounding (5.2%, p = 0.004). All effects were large. No differences existed between HARD and GRASS at any time. Irrespective of the ground surface, alternate leg bounding performed with body mass only can acutely improve indices of change-of-direction performance in women's team sports players when an appropriate post-stimulus recovery period is provided. Bounding on grass or a hard surface represents a feasible match-day practice that enhances subsequent change-of-direction performance and could therefore be used as part of practically applicable pre-match, half-time, and pitch-side (re)warm-up activities.
