Effectiveness of Flow Sheet Implementation on Diabetes Progression Screening at a Student-Run Free Clinic.

Introduction: Diabetes mellitus (DM) disproportionately affects people with low socioeconomic status (SES). Student-run free clinics (SRFC) aim to care for low SES populations and experience high clinician turnover. Flow sheets have been used to improve care for those with diabetes, yet no research has assessed the use of such a flow sheet in a SRFC.

W' expenditure and reconstitution during severe intensity constant power exercise: mechanistic insight into the determinants of W'.

The sustainable duration of severe intensity exercise is well-predicted by critical power (CP) and the curvature constant (W'). The development of the W'BAL model allows for the pattern of W' expenditure and reconstitution to be characterized and this model has been applied to intermittent exercise protocols. The purpose of this investigation was to assess the influence of relaxation phase duration and exercise intensity on W' reconstitution during dynamic constant power severe intensity exercise.

Prediction of Lunar- and Martian-Based Intra- and Site-to-Site Task Performance.

Background: This study aimed to investigate the feasibility of determining the physiological parameters associated with the ability to complete simulated exploration type tasks at metabolic rates which might be expected for lunar and Martian ambulation.

Methods: Running V̇O2max and gas exchange threshold (GET) were measured in 21 volunteers. Two simulated extravehicular activity field tests were completed in 1 G in regular athletic apparel at two intensities designed to elicit metabolic rates of ∼20.

Constructing quasi-linear V̇O2 responses from nonlinear parameters.

Oxygen uptake (V̇O2) kinetics have been shown to be governed by a nonlinear control system across a range of work rates. However, the linearity of the V̇O2 response to ramp incremental exercise would appear to be the result of a linear control system. This apparent contradiction could represent a balancing of changing V̇O2 kinetics parameter values across a range of work rates.

Standardized Exercise Tests and Simulated Terrestrial Mission Task Performance.

Background: Missions to terrestrial destinations (i.e., asteroids, the Moon, and Mars) will consist of physically challenging mission-critical tasks.

The effect of resting blood flow occlusion on exercise tolerance and W'.

It has previously been postulated that the anaerobic work capacity (W') may be utilized during resting blood flow occlusion in the absence of mechanical work. We tested the hypothesis that W' would not be utilized during an initial range of time following the onset of resting blood flow occlusion, after which W' would be utilized progressively more. Seven men completed blood flow occlusion constant power severe intensity handgrip exercise to task failure following 0, 300, 600, 900, and 1,200 s of resting blood flow occlusion.

Upper Body Aerobic Exercise as a Possible Predictor of Lower Body Performance.

Background: Aerobic exercise capacity provides information regarding cardiorespiratory health and physical capacity. However, in many populations the ability to measure whole-body or leg aerobic exercise capacity is limited due to physical disability or lack of appropriate equipment. Clinically there is a need to evaluate aerobic capacity in individuals who cannot use their legs for locomotion.
