The Effect of American Academy of Sports Medicine (NASM) Exercises on Ground Reaction Forces in People with Back Pain During Running.

The purpose of this research was to compare the effects of the American Academy of Sports Medicine (NASM) exercises on ground reaction forces in people with back pain during running. The current research was semi-experimental and applied research. Using G-Power software, the minimum sample size of 15 people was estimated for each group. The statistical population of this research was men with back pain among the students of Mohaghegh Ardabili in the age range of 20-25 years. A foot scan device (RSScan) with a sampling rate of 300 Hz was used to record plantar pressure variables. An attempt was made to run correctly on the 18-meter track to record the pressure of the soles of the feet. The effect of the group factor in the peak values of the ground reaction force during heel contact with the ground in the internal-external direction was higher in the control group compared to the experimental group (p=0.012; d=0.302). The effect of the group factor in the peak values of the ground reaction force during heel contact with the ground in the anterior-posterior direction was higher in the control group compared to the experimental group (P=0.027; d=0.243). The effect of the group factor in the peak values of the ground reaction force when lifting the foot off the ground in the vertical direction was higher in the control group compared to the experimental group (P=0.005; d=0.360). According to the obtained results, NASM exercises can improve back pain during running by affecting the ground reaction forces.
