Walking with a pedometer for 50 days significantly reduced serum triglycerides and systolic blood pressure in men walking over 8000 steps daily, but did not increase adiponectin levels.

Does walking with a pedometer improve metabolic parameters and adiponectin levels in Japanese middle-aged men?
Walking with a pedometer for 50 days, particularly >8000 steps/day, improves metabolic parameters like triglycerides and blood pressure but does not increase adiponectin levels in middle-aged Japanese men.
Absolute Event Rate: 6.6% vs 6.8%
p-value: p=0.32
Objective: To clarify the effects of walking with a pedometer on metabolic parameters, including adiponectin (APN). Methods: We recruited 44 male Japanese volunteers (age, 37 ± 9 yrs; body mass index (BMI), 24.2 ± 2.9 kg/m2; fasting plasma glucose (FPG), 96 ± 11 mg/dL; total cholesterol (TC) 190 ± 26 mg/dL; triglycerides (TG) 119 ± 80 mg/dL; HDL-C56 ± 14 mg/dL). Subjects were instructed to walk with a pedometer and record the number of steps they walked every day for 50 days. Serum adiponectin (APN) levels were measured by enzyme immunoassay. Treatment effects were examined by Wilcoxon's rank test. Results: The average number of steps was 8211 ± 2084 per day. There were significant reductions in BMI, sBP, TG and TNF-α levels after 50 days, but no changes in adiponectin levels. We then divided the subjects into 2 groups according to the steps walked per day, namely, more than 8000 steps (MT group, n=22) and less than 8000 steps (LT group, n=22) and found that the reduction in TG and BP was observed only in the MT group. Conclusions: Walking with a pedometer is effective for improving metabolic parameters, such as TG and blood pressure, but is not sufficient to increase adiponectin levels in Japanese men.
Kobayashi et al. (2006) conducted an observational in Sedentary lifestyle (n=44). Walking with a pedometer vs. Baseline was evaluated on Serum adiponectin (APN) levels (μg/mL) (p=0.32). Walking with a pedometer for 50 days significantly reduced serum triglycerides and systolic blood pressure in men walking over 8000 steps daily, but did not increase adiponectin levels.
