Prevention and Treatment of Injuries and Urinary Incontinence Among Norwegian Rhythmic Gymnasts

Rhythmic gymnastics clubs allocated to the intervention group will be visited by a physiotherapist (the PhD candidate), which will perform thorough teaching of coaches and gymnasts on how to perform the exercises in the expanded warm up program. During the same visit, before commencing PFMT, the gymnasts will have an individual session were a portable 2D ultrasound machine (GE Healthcare -Logiq e R7, GE\>12L-RS - 5-13 MHz Wideband Linear Probe) will be used to teach and assess ability to perform a correct PFM contraction. The probe is placed suprapubically and provides concurrent visible biofeedback of the PFM contraction. Adherence to the intervention will be registered weekly by the coach in a training diary and asked for as an additional question in the monthly OSTRC-H2 sent to the gymnasts. Reminders will be sent by phone to the coaches every week. To assure proper execution and motivation, the PhD candidate will perform one extra visit midterm.
