Background: Diabetes is a cosmopolitan health problem worldwide, especially in Asia. It is a metabolic disorder originating from insulin secretion deficiency, insulin performance or both. When both factors are involved, abnormal complications may result. Exercise training plays an important role in controlling diabetic parameters, including biomechanical variables.Objectives: This study aimed at assessing the effectiveness of exercise on biochemical parameters in patients with diabetes.Methods: This study was a randomized control trial. A total of 30 volunteers met the inclusion criteria and were randomly divided to 2 groups, aerobic and control, by block randomization method. This study was performed during May to October 2016 in Iran. The intervention protocol included 24 sessions (8 weeks) of aerobic exercise on the treadmill with zero slope, 3 days per week for 30 minutes per session. Intensity of training protocol was 50% to 70% maximum heart rate. Measurements of biochemical parameters were done before and after the 24 sessionsResults: There were no significant differences in anthropometric, gender, age, diabetic history, cardiac ejection fraction, and biochemical variables (P > 0.05). After 8 weeks, results were as follows: fasting blood glucose (FBS) (130.92 (45.43) Mg/dL), glycosylated hemoglobin (HbA1c) (6.62 (1.52) percent), cholesterol (150.62 (24.07) Mg/dL), triglyceride (119.62 (39.18) Mg/dL), Low density lipoprotein (LDL) (77.23 (26.73) Mg/dL), and very low density of lipoprotein (VLDL) (23.92 (7.90) Mg/dL); these were significantly reduced in the training group (P < 0.05), yet, not in the control group. Alternatively, high density lipoprotein (HDL) remained unchanged in the aerobic group (47.85 (17.83) Mg/dL) while it was increased in the control group (42.07 (8.86) Mg/dL). Also, C-reactive protein (CRP)) 2.43 (1.03) Mg/L) and microalbumin (12.32 (1.21) Mg) values didn’t change between the 2 groups.Conclusions: Eight weeks of aerobic exercise was shown to be effective in controlling biochemical parameters. However, longer training duration is needed in order to modify CRP.

Background: Providing a clear picture of neuromuscular control mechanisms and deficits in patients with chronic ankle instability (CAI) requires further investigation. Gait initiation (GI) is a perfect task to evaluate concurrent open-loop (planned GI) and closedloop (unplanned GI) neuromuscular control mechanisms in patients with CAI.Objectives: The current study aimed at evaluating neuromuscular control mechanisms via assessment of the center of pressure (COP) displacements during planned and unplanned GI in patients with CAI and healthy individuals.Methods: It was a case-control study. Twenty-two subjects with unilateral CAI and 22 healthy subjects stood on a force plate and initiated gait with maximal velocity under 2 conditions: i) planned (initiated gait after hearing the “all set” signal, when subjects felt ready to walk) and ii) unplanned (initiated gait “as soon as possible” after hearing acoustic signal). The COP parameters were assessed during the preparatory and the execution phase of GI.Results: The peak COP displacement toward swing leg decreased significantly, with P value = 0.003, in the preparatory phase of GI under planned and unplanned conditions in patients with CAI (0.028 ± 0.002) in comparison with the control group (0.038 ± 0.002). Forward velocity of the COP displacement increased in CAI patients (0.026±0.003) compared with the control group (0.018 ± 0.002) in the execution phase of GI, with P value = 0.039.Conclusions: According to the findings of the current study, both open-loop and closed-loop neuromuscular control mechanisms altered in patients with CAI.
