Mechanical horseback riding improves insulin sensitivity in elder diabetic patients.

The present study was undertaken to analyze the acute and chronic effects of exercise on insulin sensitivity in elder diabetic patients using a horseback riding therapeutic equipment (Joba). The acute effects of exercise were examined by means of a single session of Joba riding that lasted for 30 min. The average glucose infusion rates (GIR) before and during exercise were regarded as an index of the insulin action in peripheral tissues by the euglycemic clamp.

Effects of Goshajinkigan on insulin resistance in patients with type 2 diabetes.

We investigated the effects of Goshajinkigan (GJG), a Chinese herbal medicine, on insulin sensitivity in patients with type 2 diabetes using the homeostasis model assessment of insulin resistance (HOMA-R) and the euglycemic insulin clamp procedure. Daily oral administration of GJG (7.5 g/day) was performed for 1 month in 71 type 2 diabetes patients: the GJG treatment group.

Anthropometric, lifestyle and biomarker assessment of Japanese non-professional ultra-marathon runners.

Background: Anthropometric characteristics, lifestyle, and baseline biological markers of Japanese non-professional ultra-marathon runners have not been fully assessed.

Methods: We evaluated anthropometric characteristics, lifestyle, and baseline biological markers of 180 Japanese amateur ultra-marathon runners (144 males [mean age: 50.5 +/- 9.

Effects of moderate exercise on metabolic responses and respiratory exchange ratio (RER).

To counteract insulin resistance, it is necessary to increase the utilization rate of fatty acids in blood and adipose tissue. The aim of the present study was to determine the relation between metabolic responses and exercise duration from changes in the respiratory exchange ratio (RER). The mean RER during 30 minutes of moderate exercise (mean pulse 115 beats/min) was 0.
