Transient Change in Core Strength, Endurance, and Upper Limb Isometric Strength After Core Stabilisation Knockdown Protocol in Female Athletes

Objectives: We assessed the effect of change in core isometric strength and endurance on upper limb isometric strength in female athletes. Methods: In this experimental study, 32 female athletes aged 18-25 years were recruited based on the inclusion criteria. (17 cases in the experimental group and 15 cases in the control group). Before and after the core stabilization knockdown protocol, participants were assessed for isometric core strength (abdomen/back rehab 5310; rehab line), core endurance (curl-up test), and upper limb isometric strength (push up/pull down rehab 5120; rehab line). Results: The results showed a significant reduction in abdomen, back, push-up, pull-down isometric strength, and curl-up test scores in the experimental group and no significant differences in these parameters in the control group after the protocol. The experimental and control groups showed significant differences in the aforementioned parameters after the protocol. Discussion: This research suggests that performing extensive and exclusive core exercises to relieve fatigue prior to upper limb training can decrease the potential for core activation. This can ultimately lead to reduced effectiveness of upper extremity exercises or rehabilitation sessions, which can lead to upper body injuries. These exercises can be useful to enhance the knowledge regarding the sequencing of core and upper limb exercises in an athlete’s training protocols.
