Pelvic Floor Muscle Training and Neuromuscular Performance in Women's Rugby

2026年8月6日 更新者：Javier Courel Ibáñez、Universidad de Granada

This randomized controlled trial will evaluate whether a rugby-tailored pelvic floor muscle training programme reduces urinary incontinence symptoms and influences neuromuscular performance in professional and semi-professional women rugby players. A total of 48 players aged 18 to 45 years with self-reported urinary incontinence will be randomly assigned in a 1:1 ratio to the pelvic floor muscle training group or a control group.

The intervention group will complete an individualized, remotely supervised programme integrating pelvic floor muscle contractions, breathing and postural coordination, the "Knack" technique, progressive functional exercises, and rugby-relevant movement tasks. The control group will continue usual rugby training without study pelvic floor muscle training during the intervention period.

Outcomes will be measured at baseline and immediately after the intervention. The primary outcome is change in urinary incontinence severity measured with the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF). Secondary outcomes include broader pelvic floor symptom screening, jump performance, maximal isometric lower-limb force, reactive strength, and programme adherence.

详细说明

Urinary incontinence is common in women athletes and may affect training participation, confidence, concentration, and sporting performance. Rugby exposes athletes to repeated impacts, rapid decelerations, collisions, and high trunk and intra-abdominal pressure demands. Conventional pelvic floor muscle training may not fully reflect these sport-specific demands.

This study is a two-arm, parallel-group randomized controlled trial. Eligible participants will be randomized in a 1:1 ratio using a computer-generated sequence prepared by an independent researcher. Allocation will be concealed using sealed, opaque envelopes.

Participants allocated to the intervention will complete a rugby-tailored pelvic floor muscle training programme delivered remotely by certified pelvic health physiotherapists and sport scientists. The programme includes education, breathing and posture coordination, pelvic floor contractions in different positions, pre-activation before high-impact tasks ("the Knack"), progressive functional strength and landing tasks, technique correction, and individualized progression. Participants will continue their usual rugby training. Control participants will continue usual rugby training and will not complete the study exercise programme during the intervention period. After post-intervention assessment, control participants will be offered the programme materials and a remote advisory session.

Assessments will combine self-reported pelvic floor outcomes with force-plate measures. The ICIQ-UI SF and Pelvic Floor Dysfunction Screening Tool (PFD-SENTINEL) will be completed at baseline and post-intervention. Neuromuscular testing will include countermovement jumps, an isometric strength test, and a reactive jump assessment. Adherence will be monitored using participant records, physiotherapist logs, and remote-session attendance. The principal analysis will compare changes over time between groups using a mixed-effects model or equivalent repeated-measures approach, with sensitivity analyses adjusted for baseline outcome values and relevant participant and training characteristics.

实验性的：Rugby-Tailored Pelvic Floor Muscle Training Programme
Participants will continue usual rugby training and complete the remotely supervised rugby-tailored pelvic floor muscle training programme. The intervention includes pelvic floor and deep abdominal muscle coordination, breathing and posture exercises, progressive contractions in different positions, the "Knack" before impact-related tasks, functional strength and landing exercises, individualized progression, and remote technique feedback.
行为的：Rugby-Tailored Pelvic Floor Muscle Training Programme

The intervention is an individualized, remotely delivered pelvic floor training programme designed for women rugby players. It combines: (1) pelvic floor muscle awareness, activation, and complete relaxation; (2) coordination with the transversus abdominis, breathing, and posture; (3) progressive pelvic floor contractions in lying, quadruped, standing, and dynamic positions; (4) the "Knack," involving pelvic floor pre-activation before impact or high-pressure tasks; (5) progressive rugby-relevant functional tasks such as squatting, jumping, landing, and repeated impact preparation; and (6) individualized feedback from certified pelvic health physiotherapists.

Dose: 8 weeks, with 3 sessions per week. Adherence is monitored using participant self-reports, physiotherapist records, and remote-session attendance.
无干预：Control
Participants will continue their usual rugby training and will not complete the study pelvic floor muscle exercise programme during the intervention period. After post-intervention assessment, they will be offered access to the programme materials and one remote advisory session with a pelvic health physiotherapist.

措施说明
大体时间
Change in International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-SF) total score
大体时间：Baseline and immediately after the intervention (8 weeks)
Urinary incontinence symptom severity will be assessed using the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-SF). The questionnaire contains three scored items assessing urinary-leakage frequency, amount of leakage and interference with everyday life. The total score ranges from 0 to 21 points, with higher scores indicating greater urinary incontinence severity and impact and therefore a worse outcome. Change will be calculated as the score at 8 weeks minus the baseline score; a negative change indicates improvement. The primary endpoint will be the between-group difference in change from baseline to 8 weeks.

措施说明
大体时间
Change in Pelvic Floor Dysfunction Screening Tool in Female Athletes (PFD-SENTINEL) symptom count
大体时间：Baseline and immediately after the intervention (8 weeks)
Pelvic floor dysfunction symptoms will be assessed using the Pelvic Floor Dysfunction Screening Tool in Female Athletes, known as PFD-SENTINEL. The instrument includes five binary pelvic floor symptom indicators. A study-defined symptom count will be calculated by summing the number of symptoms reported, producing a score from 0 to 5. Higher scores indicate a greater number of pelvic floor dysfunction symptom categories and therefore a worse outcome. A count of at least one symptom meets the PFD-SENTINEL criterion for direct referral to a pelvic floor specialist. Change will be calculated as the score at 8 weeks minus the baseline score; a negative change indicates improvement.
Baseline and immediately after the intervention (8 weeks)
Change in Pelvic Floor Dysfunction Screening Tool in Female Athletes (PFD-SENTINEL) risk, clinical and sport-related item count
大体时间：Baseline and immediately after the intervention (8 weeks)
Risk factors and clinical and sport-related characteristics will be assessed using the Pelvic Floor Dysfunction Screening Tool in Female Athletes, known as PFD-SENTINEL. The instrument contains 28 binary risk, clinical and sport-related items. A study-defined item count will be calculated by summing the number of items reported, producing a score from 0 to 28. Higher scores indicate a greater number of characteristics associated with potential pelvic floor dysfunction and therefore a worse outcome. A count of 14 or more items meets the PFD-SENTINEL criterion for direct referral to a pelvic floor specialist. Change will be calculated as the score at 8 weeks minus the baseline score; a negative change indicates improvement.
Baseline and immediately after the intervention (8 weeks)
Change in countermovement jump height
大体时间：Baseline and immediately after the intervention (8 weeks)
Countermovement jump height will be assessed using a force plate. Participants will perform three maximal countermovement jumps with their hands maintained on their hips. Jump height will be recorded in centimetres. Higher values indicate greater vertical jump performance and therefore a better outcome. The highest value obtained from the three valid trials will be used for analysis.
Baseline and immediately after the intervention (8 weeks)
Change in maximal isometric squat peak force
大体时间：Baseline and immediately after the intervention (8 weeks)
Lower-body maximal isometric strength will be assessed using a force plate during three maximal isometric squat trials performed at a knee angle of approximately 110 degrees. Peak force will be recorded in newtons. Higher values indicate greater maximal isometric strength and therefore a better outcome. The highest peak-force value obtained from the three valid trials will be used for analysis.
Baseline and immediately after the intervention (8 weeks)
Change in Reactive Strength Index during the countermovement rebound jump
大体时间：Baseline and immediately after the intervention (8 weeks)
Reactive jump performance will be assessed using a force plate during three maximal countermovement rebound jump trials performed with the hands maintained on the hips. Reactive Strength Index will be calculated as rebound jump height in metres divided by ground contact time in seconds and will be expressed in metres per second. Higher values indicate greater reactive jump performance and therefore a better outcome. The highest Reactive Strength Index obtained from the three valid trials will be used for analysis.
Baseline and immediately after the intervention (8 weeks)
Change in self-reported amount of urinary leakage during the countermovement jump test
大体时间：Baseline and immediately after the intervention (8 weeks)
Immediately after completing the three countermovement jump trials, participants will report the amount of urinary leakage experienced during the test using the response categories from the amount-of-leakage item of the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form. The item is scored as 0 = no leakage, 2 = a small amount, 4 = a moderate amount, and 6 = a large amount. Possible scores range from 0 to 6, with higher scores indicating a greater amount of urinary leakage and therefore a worse outcome. Change will be calculated as the score at 8 weeks minus the baseline score; a negative change indicates improvement.
