Biomechanical Simulation Analysis of the Lower Extremity During Running in Males With Type A Lower Crossed Syndrome.

This study aims to examine the effects of an 8-week exercise program on male patients with lower crossed syndrome type A. Participants are randomly assigned to either an exercise group or a control group. The exercise group takes part in a supervised kettlebell-based exercise program three times per week for eight weeks, while the control group receives usual care without the exercise program. Measurements are taken before and after the intervention to compare changes between the two groups.

Study Overview

• Status: Active, not recruiting
• Conditions: Lower Crossed Syndrome
• Intervention / Treatment: Other: Kettlebell Exercise Program

Detailed Description

This randomized controlled study investigates the effects of an exercise intervention on male patients with lower crossed syndrome type A. Participants who meet the eligibility criteria are randomly assigned to either an exercise intervention group or a control group. The intervention group performs a structured kettlebell-based exercise program three times per week for a duration of eight weeks, while the control group receives usual care without participation in the exercise program. Outcome measures are collected at baseline and after completion of the intervention period to evaluate changes associated with the exercise program.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Exercise Intervention Group; Participants in this group perform a structured, supervised kettlebell-based exercise program three times per week for a duration of eight weeks.	Other: Kettlebell Exercise Program; A structured, supervised kettlebell-based exercise program performed three times per week for eight weeks. Each session lasts approximately 40 minutes and includes warm-up, kettlebell exercises targeting core and lower limb muscles, and cool-down. The program is designed to improve muscle balance and postural control in male patients with Type A Lower Crossed Syndrome .; Other Names: Structured Kettlebell Training
No Intervention: Control Group; Participants in this group receive usual care and do not participate in the exercise intervention during the study period.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pelvic Tilt Angle	Changes in pelvic tilt angle will be measured using the angle of the line connecting the Anterior Superior Iliac Spine (ASIS) and the Posterior Superior Iliac Spine (PSIS) relative to the horizontal, comparing pre- and post-intervention values between the exercise intervention group and the control group. The primary objective is to evaluate whether the kettlebell exercise program reduces the anterior pelvic tilt angle in male patients with Type A Lower Crossed Syndrome.	Baseline and 8 weeks after intervention
