Objective: The purpose of this study was to examine the immediate effects of a single massage session on hand grip strength and endurance after isometric exercise in healthy young men under controlled conditions. Methods: A total of 44 healthy young men from a university population participated in the study. They were randomized to receive either massage or passive movement intervention. Hand grip endurance and hand grip strength in both groups were recorded using a Jamar hand grip dynamometer and a digital chronometer before and after the intervention. Statistical analysis was performed using the Wilcoxon, Mann-Whitney, and paired t test as well as independent t test. Results: Pre-and postmean hand grip endurance times for the massage group were 38.4 ± 12 and 46.5 ± 13 seconds (P b .001), and hand grip strength values were 43 ± 5.6 and 45.7 ± 5.3 kg (P = .077). Pre-and postmean hand grip endurance times for the passive movement group were 33 ± 12.3 and 31.9 ± 10.7 seconds (P = .513), and hand grip strength values were 42.8 ± 6 and 42.9 ± 5.6 kg (P = .854). Conclusion: Immediately after 1 session of massage to the forearm and hand, the grip endurance improved in a group of healthy young men. However, passive movement of the upper limb for 1 session did not enhance grip performance.

Purpose The rising prevalence of childhood obesity in the past decades has caused non-alcoholic fatty liver disease (NAFLD) to become the most common cause of pediatric chronic liver disease worldwide. This study was aimed at determining the effect of vitamin D (Vit D) on ultrasonography and laboratory indices of NAFLD and some blood biochemical indicators in children. Methods In this interventional study liver ultrasonography was performed in 200 children with overweight and obesity. A 108 had fatty liver among which 101 were randomly divided into two groups of study (n=51) and control (n=50). The study group was treated with Vit D, 50000 U once a week whereas the control group received placebo with the same dose and package, both for 12 weeks. At the end of the intervention lab tests and ultrasound study was performed once again to evaluate the response to treatment. Results It was found out that Vit D supplementation improved the fatty liver grade in the study group. The mean changes in hemoglobin (Hb), uric acid, highdensity lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), insulin, albumin and alanine aminotransferase (ALT) was significantly higher in the study group compared to controls ( p <0.05). After the intervention and means adjustment, a significant difference was obtained in HDL-C, insulin, LDL-C and homeostasis model assessment of insulin resistance (HOMA-IR) between the two groups. Conclusion Vit D supplementation in addition to improving the fatty liver grade in ultrasonography and increasing the blood Vit D level, increases the HDL and Hb level besides decreasing uric acid, LDL, HOMA-IR, insulin and ALT levels.
