Effects of Bulgarian Exercises on Lower Limb Function in Children

Effects of Bulgarian Bag Exercise on Lower Limb Function, Posture and Balance Among School Going Children

The objective of this study is to investigate the Effect of Bulgarian bag exercises on lower limb function, posture and balance among school going students. In this investigation, our study will include 379 participants girls and boys in our study. Non-Probability Convenient sampling will be used in this research. In this investigation, will collect data from Lahore primary school going girls and boys. The sample that will be included in our study will be 8 to 16 years of age, with both genders, Informed consent, Healthy children without any diagnosed physical or neurological impairments that could affect motor skills or agility. This study use following tools in our study Postural awareness scale PAS-E, Berg balance scale, The lower extremity functional scale.

Study Overview

• Status: Recruiting
• Conditions: Child, Only
• Intervention / Treatment: Other: Bulgarian Bag Exercises

Detailed Description

Bulgarian Training Bag is a training equipment used in strength training, Plyometrics, Weight training, aerobic exercise, and fitness in general. Bags are made of leather or synthetic leather and filled with sand; Weigh between 3 to 38 kg and have flexible handles to allow training of the upper and lower body, and to improve the prehensile strength. Instead, Leisure Physical Activity should be thought of as all physical activity behavior that emanates from an unconscious drive for movement. Regular participation in physical activity is important for overall health. It provides children with immediate social, mental and physical health benefits, such as reducing symptoms of depression, improving academic and cognitive performance, promoting healthy bone structure, skeletal health supporting muscle growth and the development of the body's vital organs, particularly the heart and lungs, improving health related fitness, muscular strength and, preventing children from becoming overweight.

Intervention / Treatment

Experimental: Interventional Group(Bulgarian Bag Exercise Program); The Bulgarian Bag exercises will be performed under the guidance of a trained physical therapist or instructor. Key exercises will include squats, lunges, deadlifts, and shoulder presses, all performed with the Bulgarian Bag to target lower body strength, balance, and coordination. Progressions (e.g., increasing repetitions or load) will be made gradually as participants adapt to the exercises.

Other: Bulgarian Bag Exercises; The Bulgarian Bag exercises will be performed under the guidance of a trained physical therapist or instructor.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Postural Awareness Scale PAS-E	Body posture refers to the position of a person's body in space and the alignment of body parts in relationship to one another and to the environment at one point in time. Postural awareness is informed via receptors in joints, muscles, ligaments, and connective tissue, which is then integrated in the central nervous system. Importantly, postural awareness is influenced by mental processes, including attention, interpretation, and appraisal of bodily sensation, as well as by affect, emotions, and attitudes.	11 weeks
Pediatrics Berg Balance Scale	The Berg Balance Scale has proven to be a reliable and valid tool for assessing balance and predicting fall risk across various populations, including older adults, individuals with neurological conditions (e.g., stroke, Parkinson's disease), and those recovering from orthopedic surgery. Its high test-retest and inter-rater reliability, as well as its strong construct, criterion, and concurrent validity, support its widespread use in clinical practice and research. However, like any assessment tool, it should be used as part of a comprehensive evaluation that includes other clinical assessments and considerations	11 weeks
Lower Extremity Functional Scale (LEFS)	The Lower Extremity Functional Scale (LEFS) is a self-reported questionnaire used by physical therapists and other healthcare providers to assess a person's functional ability related to lower extremity (leg) tasks. It is widely used to evaluate the degree of difficulty experienced by individuals with lower extremity injuries or conditions in performing various daily activities.	11 weeks
