Brief Summary

This observational cross-sectional study aims to investigate the association between participation in high-impact sports, physical activity level, and urinary incontinence in young adults. The study will compare six groups based on sex and physical activity level: male and female high-impact sports participants, physically active males and females who do not participate in high-impact sports, and sedentary males and females. Participants aged 18-35 years will undergo a single assessment including sociodemographic and medical information, physical activity assessment, urinary incontinence questionnaires, sport-related characteristics, psychosocial questions regarding the influence of social taboos on questionnaire responses, lower-limb muscle strength testing using a load cell, and vertical jump performance assessment. The study aims to describe the prevalence, severity, type, and impact of urinary incontinence across different activity levels and sexes, and to explore potential associations with lower-limb strength, jump performance, and sport-related characteristics.

Conditions

Urinary Incontinence (UI); Urinary Incontinence , Stress

Keywords

urinary incontinence; physical activity; high-impact sports

Outcome Measures

Primary Outcomes (1)

• Urinary incontinence severity

  Urinary incontinence severity assessed using the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF). Higher scores indicate greater symptom severity and impact on quality of life. The total score ranges from 0 to 21, with higher scores indicating more severe urinary incontinence symptoms and greater impact on quality of life.

  Baseline (single study visit)

Secondary Outcomes (4)

• Urinary incontinence-related quality of life

  Baseline (single study visit)

• Lower-limb muscle strength

  Baseline (single study visit)

• Vertical jump performance

  Baseline (single study visit)

• Physical activity level

Eligibility Criteria

• Age: 18 Years - 35 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)
• Sampling Method: Probability Sample

Study Population

The study population will consist of community-dwelling adults aged 18-35 years recruited from the general population and sports clubs. Participants will include males and females who regularly participate in high-impact sports, physically active individuals who do not participate in high-impact sports, and sedentary individuals. Recruitment will be conducted through social media, institutional advertisements, sports clubs, and snowball sampling. All participants will voluntarily contact the research team and will undergo a single face-to-face assessment after providing written informed consent.

You may qualify if:

• Adults aged 18 to 35 years.
• Male or female participants.
• Able to understand and provide written informed consent.
• Belong to one of the following groups:
• Regular participation in high-impact sports (≥2 training sessions per week for at least the previous 2 years).
• Physically active individuals meeting the World Health Organization recommendations (≥150 minutes/week of moderate-intensity activity, ≥75 minutes/week of vigorous-intensity activity, or an equivalent combination), without regular participation in high-impact sports.
• Sedentary individuals who do not meet the World Health Organization physical activity recommendations.

You may not qualify if:

• Pregnancy or childbirth within the previous 12 months.
• Current or recent urinary tract infection.
• History of urogynecological disease or pelvic/urogynecological surgery.
• Body mass index (BMI) \>35 kg/m².
• Inability to understand or complete the study procedures or questionnaires in Spanish or English.
