Abstract

aims / objectives of the research: The increase in cardiovascular diseases among the elderly is one of the world's leading causes of death, and aerobic exercise is one way to prevent these conditions. Aim and Objective: This study aimed to determine the effect of 8 weeks of walking and folate consumption on plasma homocysteine levels in non-athletic older women. Materials and Methods: In this experimental study, 20 non-athletic older women aged 50 to 60 volunteered to participate and were randomly assigned to one of two groups: exercise+folic acid (10 persons) or exercise+placebo (10 persons). Both groups completed a walking program of eight weeks (3 sessions per week, each lasting 60 minutes). Following the conclusion of the exercise program, blood samples were collected and analyzed using independent and dependent t-statistics. After completing the walking exercise program for eight weeks, the plasma homocysteine levels fell considerably in both the exercise+supplement (P=0.002) and exercise+placebo (P=0.005) groups. Results: After completing the walking exercise program for eight weeks, the plasma homocysteine levels fell considerably in both the exercise+supplement (P=0.002) and exercise+placebo (P=0.005) groups.Conclusion: According to the present study's findings, elderly individuals should engage in walking exercises and take supplemental folate to lower plasma homocysteine and prevent cardiovascular risks.

Abstract

Background: Low back pain (LBP) is a global health concern influenced by biomechanical factors, including lumbar alignment. Altered lumbar curvature (hyperlordosis/hypolordosis) may disrupt posture, plantar pressure distribution, and postural stability, contributing to LBP pathophysiology. Aim: This study investigated the impact of lumbar alignment on plantar pressure patterns and postural sway in individuals with LBP. Methods: Thirty-six participants (18–25 years) were categorized into hyperlordosis, hypolordosis, and normal lordosis groups. Lumbar curvature was measured using a flexible ruler, while plantar pressure and center of pressure (COP) parameters were assessed via the Zebris FDM-S platform during bipedal and unipedal standing. Statistical analysis included ANOVA and Tukey’s post hoc tests (SPSS v26, p<0.05). Results: The normal lordosis group exhibited significantly smaller COP confidence ellipse parameters (minor/major axis length, area) and lower postural sway compared to hyperlordosis and hypolordosis groups (p<0.05). Anterior-posterior plantar pressure asymmetry was pronounced in hyperlordosis (anterior shift) and hypolordosis (posterior shift). No significant differences were observed in mediolateral COP displacement or bilateral foot symmetry (p>0.05). Conclusion: Normal lumbar alignment enhances postural stability and balanced plantar pressure distribution, whereas hyperlordosis and hypolordosis correlate with increased postural fluctuations and asymmetric foot loading. Rehabilitation strategies targeting lumbar alignment may improve biomechanical outcomes in LBP management.
