Brief Summary
There is a high prevalence of urinary incontinence (UI) among female athletes and exercisers, especially in sports including high impact activities and heavy weightlifting. CrossFit and functional fitness is a popular exercise form, including a combination of heavy lifting and high impact activities at high intensities. In several recent studies, high prevalence rates of UI have been reported among female CrossFit/functional fitness exercisers. UI is defined as "the complaint of involuntary loss of urine". Stress urinary incontinence (SUI) is the most common type of UI and is defined as "the complaint of involuntary loss of urine on effort or physical exertion (e.g. sporting activities), or or sneezing or coughing". Urinary leakage during sport activities may affect athletes' and exercisers' performance, cause bother, frustration and embarrassment and furthermore lead to avoidance and cessation of sport activities. Pelvic floor muscle (PFM) training is highly effective in treating SUI in the general female population. However, evidence of the effect of PFM training in exercisers participating in high impact and heavy weightlifting activities is sparse. The purpose of this assessor-blinded randomized controlled trial (RCT) is to assess the effect of PFM training on symptoms, bother and amount of SUI in female CrossFit/functional fitness exercisers.

Outcome Measures
Primary Outcomes (1)
The International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF)
A reliable and valid questionnaire assessing self-reported prevalence, amount of leakage, bother and type of UI. A change in ICIQ-UI-SF score of 1.58 points will be considered as between-treatment minimum important difference.
Change in total score from baseline at four months
Secondary Outcomes (7)
Pelvic Floor Muscle Resting Pressure
Change in pressure value from baseline at four months
Pelvic Floor Muscle Strength
Change in pressure value from baseline at four months
Pelvic Floor Muscle Endurance
Change in pressure value from baseline at four months
Self-Efficacy Scale for Practicing Pelvic Floor Exercises (SESPPFE)
At baseline in both groups. Participants in the intervention group will also be asked to answer the questionnaire again within the first month of the intervention period
Anal incontinence
Change in score from baseline at four months
- +2 more secondary outcomes
Study Arms (2)
Intervention Group
EXPERIMENTAL16 weeks home-based PFM training program with weekly follow-up by a physiotherapist
Control Group
NO INTERVENTIONNo intervention
Interventions
The intervention will consist of a home-based PFM training program with weekly follow-up by phone by a physiotherapist. Before commencing PFM training, the participants in the intervention group will have an individual session with a physiotherapist including thorough teaching on how to perform a correct PFM contraction (clinical exams of pelvic floor muscle function by observation and vaginal digital palpation) and instructions on how to perform the training program. The program consists of 3 sets of 8-12 maximum contractions per day. An electronic app (Athlete monitoring) will be used to assess adherence to the program. The participants will be asked to register their training sessions in a personal account. A reminder to adhere to the program will be sent by phone. The training period will be 16 weeks and the exercises will take approximately 10 minutes per day to perform.
Eligibility Criteria
You may qualify if:
- Age ≥18
- ≥ 6 months of consistent participation in CrossFit or functional fitness training
- Participating in ≥ 3 sessions of cross-fit training per week
- Self-reported SUI and a total score on ICIQ-UI-SF of ≥ 3. A change of the ICIQ-UI-SF score of 2.5 has been identified to be the minimal important difference (MID) and 1.58 as between-treatment MID (Nystrom et al., 2015).
- No musculoskeletal injuries for the past 6 months with negative effect on training participation
You may not qualify if:
- Ongoing pregnancy, or planning to get pregnant during the intervention period
- History of hysterectomy or pelvic surgery to correct UI or POP
- History of musculoskeletal injuries for the past 6 months with negative effect on training participation
- Parous women who are ≤12 months post-partum
