The primary objective within the current study is to compare the acute and chronic effects of eccentric training and IASTM on the dorsiflexion ROM. To reduce the risk of Achilles tendinopathy, stretching and eccentric (lengthening) exercises are postulated to improve ankle dorsiflexion. An eccentric exercise lengthens an active muscle while it is under load. Consequently, eccentric calf muscle exercises can also increase ankle dorsiflexion through an increase in calf muscle strength. For the above mentioned reasons, a combination of stretching exercises and eccentric (lengthening) exercises are suggested as preventive intervention to increase ankle dorsiflexion. The biggest goal of IASTM is to remove scar tissues and facilitate a return to normal function following soft tissue recovery. These Techniques, eccentric stretching and IASTM works towards bringing back the normal range of motion and strength, allowing individuals to regain mobility and return to their usual activities and we will find out the better option from these.
