The study aimed to determine if yoga poses and conventional physiotherapy were more effective than deep breathing exercises and conventional physiotherapy in reducing kinesiophobia in amateur football players with chronic ankle instability. 28 participants were divided into an experimental and control group, with the experimental group receiving yoga poses and conventional physiotherapy, and the control group receiving deep breathing exercises and conventional physiotherapy.

Yoga is an Indian mind-body practice that has become well-known all over the world. During standing, sitting, and lying supine or prone, participants' bodily motions are gradual and have a wide range of motion. It has been demonstrated that yoga practice improves balance, coordination, emotional and mental well-being which assist in increasing joint flexibility, range of motion (ROM) and muscle strength.

Three yoga poses namely, the crescent lunge pose (Halasana), warrior II pose (Virabhadrasana II), and triangle pose (Trikonasana). These yoga manoeuvres reduce pain, which enhances people's quality of life. Reports indicate that yoga alters the perception of pain and influences brain waves. Since yoga promotes both pain treatment and psychosocial healing, it has been a popular alternative pain management technique in recent years for Kinesio phobia.

Injured athletes can benefit from deep breathing as a non-pharmacological pain management technique that increases localized tissue circulation and diverts attention from their discomfort. Inducing a shift in sympathetic nervous system activity by reducing stress hormone levels and activating the diaphragm by stimulating the vagal nerve, which regulates pain perception, guided or focused deep breathing functions as a mindful meditation technique.

The most successful strategy for collegiate athletes to handle stress and prepare for competition was deep breathing. Additionally, it has been demonstrated that deep breathing can assist individuals with chronic musculoskeletal pain manage their condition effectively, reducing movement fear and enhancing subjective wellbeing and quality of life.

Conventional physical therapy includes exercises for strengthening and flexibility as well as training for agility and balance. These therapies aim to improve muscular strength, speed, agility, and neuromuscular control; restore a normal gait pattern without the use of assistive devices; improve balance; and increase range of motion and flexibility. Conventional physiotherapy uses a range of techniques centered on function restoration, strength enhancement, and injury prevention to address these problems.

By combining conventional physiotherapy with relaxation techniques like three typical yoga postures and deep breathing technique, our method not only helps people with Kinesio phobia but also improves their ankle range of motion, balance, and coordination so they can actively resume their daily lives.
