Acute/Subacute and Sub-Chronic Oral Toxicity of a Hidroxytyrosol-Rich Virgin Olive Oil Extract.

The objective of this study was to determine the acute (one single dose), subacute (14 days), and sub-chronic (90 days) toxicity of an aqueous virgin olive oil (VOO) extract rich in hydroxytyrosol in rats. For acute/subacute toxicity, rats were divided into three groups. The control group received distilled water ( = 9), another experimental group received a single dose of 300 mg/kg ( = 3), and a third group received one dose of 2000 mg/kg ( = 4) during 14 days.

[Relationship between quality of life, physical activity, nutrition, glycemic control and sarcopenia in older adults with type 2 diabetes mellitus].

Introduction: The term sarcopenia is defined as age-related loss of skeletal muscle mass and function, with a consequent impact on quality of life. However, there is a lack of studies examining the prevalence of sarcopenia in patients with type 2 diabetes mellitus (DM).

Objectives: To analyze the prevalence of sarcopenia in patients over 65 years with type 2 DM and the influence of physical activity, diet, glycemic control, sex, age, and quality of life.

A Novel Electromyographic Approach to Estimate Fatigue Threshold in Maximum Incremental Strength Tests.

Evaluation of muscular fatigue thresholds in athletes performing short-duration and explosive exercises is difficult because classic parameters do not suffer large variations. Therefore, the aim of this study was to develop a new method to estimate the fatigue threshold in single muscles. Our approach is based on electromyographic data recorded during a maximum incremental strength test until the one repetition maximum is reached.
