Effects of Core Stabilization Exercise Programs on Changes in Erector Spinae Contractile Properties and Isokinetic Muscle Function of Adult Females with a Sedentary Lifestyle

Abstract

This study aimed to investigate the effect of core stabilization exercises on the contractile properties and isokinetic muscle function of adult females with a sedentary lifestyle. We enrolled 105 adult females. Tensiomyography was performed on the erector spinae, and the isokinetic muscular functional test was performed on the trunk at an angular velocity of 60°/s and 90°/s. All participants performed the exercise for 60 min per day, 3 times a week, for 7 weeks. A Wilcoxon signed-rank test was performed at a significance level of 0.05. Tensiomyography (TMG) of the erector spinae revealed no significant post-exercise change in the contraction time; however, there was a significant post-exercise increase in the maximum radial displacement and mean velocity until 90% of the TMG was displaced. Additionally, the isokinetic muscular functional test of the trunk revealed a significant post-exercise increase in almost all variables. Our findings demonstrated that the core stabilization exercise reduced stiffness in the erector spinae, increased the velocity of erector spinae contraction, and effectively improved the isokinetic muscular function of the trunk.

Effects of Lumbar Stabilization Exercises on Isokinetic Strength and Muscle Tension in Sedentary Men

“…So, the participants were requested to refrain from caffeine intake for 24 h before the measurement. Moreover, myofascial treatment and exercise that can cause muscle fatigue were restricted 48 h before measurement [ 26 ]. To apply the TMG to the participants’ ESM, they were guided to lie face down on the bed and position their legs at 5° flexion using a cushion, and wedge cushions were placed on the ankle and the anterior superior iliac spine (ASIS) to ensure minimal lumbar lordosis [ 27 ].…”

Effects of Regular Aerobic Exercise on Cardiovascular Health Factors and Heart Function in Sedentary Male Office Workers

“…In modern society, people spend a substantial amount of time sitting down, which has led to mounting interest in the consequent decline in physical activity, that is, a sedentary lifestyle. Therefore, it has been stated that exercise to strengthen muscles is an essential and indispensable factor in preventing the risk factors for musculoskeletal disorders caused by an increase in sedentary lifestyle [6].…”
