Eligibility
Age
18 Years to 59 Years
Inclusion criteria
Inclusion criteria: Individuals aged between 18 and 59 years; muscle strength difference between lower limbs greater than or equal to 10 per cent in the knee extensor musculature (quadriceps), indicating asymmetry; medical clearance for training, granted by the physician associated with the study (Dr. Francisco Wekerlin Morozowski); signing the Informed Consent Form; completing 75 per cent of the proposed training sessions if selected for the intervention
Exclusion criteria
Exclusion criteria: Having conditions that prevent the completion of questionnaires, understanding of instructions, and performance of tests (e.g., severe vestibular deficits, mobility deficits, and cognitive impairment); having systolic blood pressure greater than or equal to 140 mmHg or diastolic blood pressure greater than or equal to 90 mmHg; having more than one risk factor for thromboembolism, which includes: body mass index greater than or equal to 30 kg/m². diagnosis of chronic inflammatory disease. history of pelvic, hip, and femur fractures. major surgeries in the last 6 months. diagnosis of varicose veins in the last 6 months. family history of deep vein thrombosis and pulmonary embolism. use of oral contraceptives. tobacco use
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| A significant increase in muscle strength (peak torque, N.m) is expected, verified using the Biodex Multi-joint System Dynamometer (Biodex Medical Systems, Inc., Shirley, NY, USA) by comparing the pre- and post-intervention (12 weeks) measurements. | — |
Secondary
| Measure | Time frame |
|---|---|
| A significant reduction in the inter-limb strength asymmetry of the knee extensor musculature, identified in the initial assessment, is expected. This will be verified using the Biodex Multi-joint System Dynamometer (Biodex Medical Systems, Inc., Shirley, NY, USA) by comparing the pre- and post-intervention (12 weeks) measurements.;A significant increase in muscle thickness (cm) is expected, verified using the portable B-mode ultrasound device Version 1.10 (Konica Minolta, model Sonimage HS1) by comparing the pre- and post-intervention (12 weeks) measurements.;A significant improvement in gait performance is expected, evaluated through spatiotemporal and variability parameters at different walking speeds (self-selected and fast walking speed). Gait parameters will be assessed and analyzed using an instrumented walkway, the Zeno Walkway (120Hz), and the ProtoKinetics Movement Analysis Software, by comparing the pre- and post-intervention (12 weeks) measurements. | — |
