Far from the walking pace. Ecological and evolutionary consequences of the suboptimal locomotion speeds in non-adult humans.

Introduction: Locomotion activities are part of most human daily tasks and are the basis for subsistence activities, particularly for hunter-gatherers. Therefore, differences in speed walking-related variables may have an effect, not only on the mobility of the group, but also on its composition. Some anthropometric parameters related to body length could affect walking speed-related variables and contribute to different human behaviors.

Micronutrient supplement intakes among collegiate and masters athletes: A cross-sectional study.

Objective: In our cross-sectional study, we evaluated micronutrient supplementation intake among Collegiate and Masters Athletes.

Methods: We conducted a cross-sectional study to assess micronutrient supplementation consumption in Collegiate and Masters Athletes, comparing sex and sport classification within each respective group. Micronutrient supplement consumption data were measured using a Food Frequency Questionnaire.

A Comparison of Substrate Utilization Profiles During Maximal and Submaximal Exercise Tests in Athletes.

Background: Exercise is primarily sustained by energy derived from lipids (plasma free fatty acids and intramuscular triglycerides), and glucose (plasma glucose and muscle glycogen). Substrate utilization is the pattern by which these fuel sources are used during activity. There are many factors that influence substrate utilization.

Validation of a Newly Developed Food Frequency Questionnaire to Assess Dietary Intakes of Magnesium.

Magnesium (Mg) intake is an important indication of an individual's Mg status, but no validated food frequency questionnaire (FFQ) to assess intake currently exists. The purpose of this study was to develop and investigate the validity of a semi-quantitative Mg food frequency questionnaire (MgFFQ) against a 14-day food diary to assess average daily Mg intakes. In this cross-sectional study, 135 adults aged 18 to 75 completed the 33-item MgFFQ and a 14-day food diary to assess their Mg intakes.

Low dietary magnesium intake alters vitamin D-parathyroid hormone relationship in adults who are overweight or obese.

Vitamin D metabolism is dependent on magnesium (Mg) as a cofactor; therefore, poor Mg status may alter the relationship between vitamin D metabolite serum 25-hydroxyvitamin D (s25OHD) and serum parathyroid hormone (sPTH). We hypothesized that low dietary Mg intake may alter sPTH response to s25OHD in a population with excess body weight, thereby leading to a worsening of cardiometabolic health. To explore this hypothesis, we conducted a cross-sectional study on adults who were either overweight or obese (owt/ob).

The Endocrine Role of Bone in Cardiometabolic Health.

Purpose Of Review: The purpose of this review is to discuss the current knowledge about major bone regulating hormones vitamin D, parathyroid hormone (PTH), estrogen and bone metabolism markers osteocalcin (OC), bone-specific alkaline phosphatase (BAP), N-terminal propeptide of type 1 collagen (P1NP), and c-terminal type 1 collagen (CTX) and their mechanistic effects on cardiometabolic health.

Recent Findings: Bone regulating hormones, nutrients, and turnover markers influence different aspects of cardiometabolic health including body composition, cardiovascular function, and glycemic control. While most observational research supports a relationship between bone as an endocrine organ and cardiometabolic outcomes, there are limited human clinical trials to strengthen a causal link between the two.
