Objective:The objective of this study was to investigate the effect of squat exercises with weight shift on muscle strength and postural control during pregnancy.
Materials and Methods:The squat group comprised 21 pregnant women in their 20s and 30s with no exercise habits, while thecontrol group comprised 20 randomly extracted pregnant women in their 20s and 30s with no exercise habits.The squat group was instructed to perform two sets per day of squat exercises with weight shift in the anterior, posterior, right, and left directions, with 10 repetitions counted as one set, for 10 weeks.Astabilometerwas used to measure postural control abilityinthe second and the third trimesters. Muscular strength was taken as the toe grip force and quadriceps muscle strength before and after the intervention.
Results:In the squat group, significant increases were seen inthe index of postural stability and the stability area, and significant decreases were seen in the average rectangular area. In the intervention group, significant decreases were seen in the rectangular area in the posterior, right, and left directions. A significant increase in muscular strength wasseen after the intervention in toe grip force only.
Conclusion:Every day squat exercisesare performed during pregnancy improves postural control.The improvement of postural control during squat movements is thought to have a greater impact on plantar sensation than on muscle strength. These findings suggest that squat exercises with weight shift may promote fall prevention.
