Brief summary
JUSTIFICATION: Urinary incontinence is highly prevalent among women who play high impact sports such as running. that observed one of the possible reasons for this high prevalence is delayed activation of the pelvic floor in relation to the abdominal muscles. The use of minimalist shoes during the race produces changes in muscle and joint biomechanics and efficiency in the race. However, to date no studies evaluating the influence of footwear in the musculature of the pelvic floor during the race. OBJECTIVE: Describe and compare the electromyographic activity of the muscles of the pelvic floor and abdominal during the race with conventional shoes and minimalist. DESIGN: cross-over study experimental, analytical and prospective. METHODOLOGY: conventional and minimalist: 50 healthy young women, 6- randomly distributed in two groups will be included to characterise the electromyographic activity of the pelvic floor muscles before and during running at 6-9-11 km/h with the two types of running shoes. A baseline assessment will be performed to confirm that the women meet the inclusion and exclusion criteria. The ability to run a 10-minute treadmill at a speed of 6-9-11 km/h will be assessed, as well as the ability to adequately contract the pelvic floor muscles. The group of 50 women will initially run randomly with conventional running shoes or with minimalist running shoes, and then, after a 10-minute washout period, will run with the other type of running shoe, i.e. if a participant in the first phase used conventional running shoes, she will run with a minimalist running shoe in the second phase. The cadence of step, the range of movement of the femur and the EMG recording with electromyographic sensors of the pelvic floor musculature (using an intravaginal probe of the germproof brand), abdominal (internal and external oblique), spinal erectors and gluteus (using a surface sensor) in relation to the cycling gait will be collected and recorded with barographic sensors. The variables to be included in the electromyography for each muscle in relation to the gait cycle will be: onset of activation, duration, intensity and synergy with their corresponding standard deviation.

|---|---|---|
| Electrical activation of the pelvic floor musculature, abdominal, gluteus maximus and lumbar erectors during the race in nulliparous women with sneakers traditional and minimalist | Basal, 0.5, 1.0, 1.5 minutes after the start of the test. | PeriformTM vaginal probe Will collect the EMG activity of the muscles of the pelvic also register with superficial electrodes EMG abdominal, gluteus maximus and lumbar erectors. Records are made in a single session with washout periods in accordance with previous studies that have collected the activity of the EMG activity PF during treadmill running different speeds. |
