The Effect of Progressive Lumbar Stability Exercise on the Transversus Abdominis Muscle Thickness and Lower extremity muscle Fatigue Index in Soccer Players

Abstract

This study aimed to assess the effects of progressive lumbar stability exercises and lumbar stability exercises on changes in the transversus abdominis muscle thickness and lower extremity muscle fatigue index in soccer players. Ten subjects were assigned to undergo training in each of the 2 groups, namely, the progressive lumbar stability exercise group and lumbar stability exercise group. Each intervention session lasted for 30 min, and 4 sessions were conducted in a week for 6 weeks for soccer players of S. University in Jeonnam, Korea. Changes in the transversus abdominis muscle thickness and lower extremity muscle fatigue index were measured using ultrasound and surface electromyogram. The results of the ultrasound measurement for the transversus abdominis muscle thickness indicated that progressive lumbar stability exercises were more effective than lumbar stability exercises. The results of the lower extremity muscle fatigue index measurements using surface electromyogram indicated that the fatigue index decreased in the progressive lumbar stability exercise group. Progressive lumbar stability exercise is believed to have put more workload during the shaking of the limbs, leading to increased stability and increased efficiency of the lower extremity muscle, thereby decreasing the fatigue index. Therefore, progressive lumbar stability exercises can be an effective measure for preventing injuries and improving the game performance of sports players by increasing the transversus abdominis muscle thickness and decreasing the lower extremity muscle fatigue index.

Effects of low-frequency electrical stimulation on cumulative fatigue and muscle tone of the erector spinae

“…That is, microcurrent enhances electrical and chemical processes, which assist the healing process, returning damaged muscle tissues to a normal state 23 ) . Reduction of the median frequency value indicates a reduction in muscle fatigue 22 , 24 ) , and muscle tone and microcurrent stimulation is more effective for the recovery of muscle fatigue and muscle tone than only taking a rest. The microcurrent therapy increased collagen formation speed in the recovery of damaged cells more than in the TENS therapy, which is why the microcurrent stimulation had a more positive effect on muscle fatigue and muscle tone.…”
