Exercise-Induced Weight Loss is More Effective than Dieting for Improving Adipokine Profile, Insulin Resistance, and Inflammation in Obese Men.

The adipokines chemerin and adiponectin are reciprocally related in the pathogenesis of insulin resistance and inflammation in obesity. Weight loss increases adiponectin and reduces chemerin, insulin resistance, and inflammation, but the effects of caloric restriction and physical activity are difficult to separate in combined lifestyle modification. We compared effects of diet- or exercise-induced weight loss on chemerin, adiponectin, insulin resistance, and inflammation in obese men. Eighty abdominally obese Asian men (body mass index [BMI] ≥ 30 kg/m(2), waist circumference [WC] ≥ 90 cm, mean age 42.6 years) were randomized to reduce daily intake by ~500 kilocalories (n = 40) or perform moderate-intensity aerobic and resistance exercise (200-300 min/week) (n = 40) to increase energy expenditure by a similar amount for 24 weeks. The diet and exercise groups had similar decreases in energy deficit (-456 ± 338 vs. -455 ± 315 kcal/day), weight (-3.6 ± 3.4 vs. -3.3 ± 4.6 kg), and WC (-3.4 ± 4.4 vs. -3.6 ± 3.2 cm). The exercise group demonstrated greater reductions in fat mass (-3.9 ± 3.5 vs. -2.7 ± 5.3 kg), serum chemerin (-9.7 ± 11.1 vs. -4.3 ± 12.4 ng/ml), the inflammatory marker high-sensitivity C-reactive protein (-2.11 ± 3.13 vs. -1.49 ± 3.08 mg/L), and insulin resistance as measured by homeostatic model assessment (-2.45 ± 1.88 vs. -1.38 ± 3.77). Serum adiponectin increased only in the exercise group. Exercise-induced fat mass loss was more effective than dieting for improving adipokine profile, insulin resistance, and systemic inflammation in obese men, underscoring metabolic benefits of increased physical activity.

Consensus statements and guideline for the diagnosis and management of plantar fasciitis in Singapore.

Introduction: Plantar fasciitis (PF) is a common cause of heel pain among the general population. The lack of standard practice guideline in Singapore presents challenges in education and clinical practice for this painful condition. These consensus statements and guideline were developed to streamline and improve the management of PF, covering key aspects such as diagnosis, investigations, risk factors, treatment modalities, monitoring and return to work/play. Method: A multidisciplinary expert panel consisting of 6 sports physicians, 2 orthopaedic surgeons, 2 podiatrists and 1 physiotherapist from SingHealth Duke-NUS Sport & Exercise Medicine Centre (SDSC) was convened based on their clinical and academic experience with PF. The Grading of Recommen-dations, Assessment, Development and Evaluations (GRADE) approach was used to evaluate the quality of the evidence and subsequently prepare a set of clinical recommen-dations pertaining to the manage-ment of PF. A modified Delphi process was used to reach consensus. Results: Eighteen consensus statements were developed to cover key components of PF management, from initial diagnosis to treatment modalities and finally, clinical progression. They were subsequently consolidated under a proposed treatment pathway guideline for PF. Conclusion: The SDSC consensus statements and guideline provide concise recommendations for the management of PF in Singapore.
