Excess body weight is associated with an imbalance between energy expenditure and dietary intake but evidence on the association between diet quality and body composition remains equivocal. Rather than relying on differences in diet quality between overweight/obese and normal weight adults, this study examined the association between the Healthy Eating Index 2010 (HEI-2010) and body fatness on a continuous scale, independent of physical activity (PA). Further the association between components of the HEI-2010 and risk for overweight/obesity was explored. 407 adults (27.6 6 3.7 years) provided at least two 24-hour diet recalls over a period of 14 days, which were …
Mechanical Power And Efficiency Of Level Walking With Different Stride Rates, Brian R. Umberger, Philip E. Martin
Mechanical Power And Efficiency Of Level Walking With Different Stride Rates, Brian R. Umberger, Philip E. Martin

Walking humans prefer to use the stride rate that results in the lowest rate of metabolic energy expenditure. Mechanical power requirements have been suggested to underlie the metabolic response, but mechanical power is consistently reported to be minimal at stride rates 20–30% lower than preferred. This may be due to limitations in how total mechanical power has been computed, as well as a failure to account for the efficiency with which muscular work is done. We investigated how mechanical power and efficiency depend on stride rate in walking, with both quantities computed from the work done by the hip, knee …
The Effect Of Carried Loads On The Combative Movement Performance Of Men And Women, Philip E. Martin, Richard C. Nelson
The Effect Of Carried Loads On The Combative Movement Performance Of Men And Women, Philip E. Martin, Richard C. Nelson
Philip E. Martin
This study examined the effect of carrying typical military loads of varying magnitude on the combative movement performance of 16 male and 14 female subjects. The subjects performed a series of tests which included a 25 yard spring, standing long jump, agility run, reaction - movement test, and ladder climb. These tests were performed under five load conditions ranging from a baseline condition (no load) to one of approximately 37 kg. The results from these performance tests constitute valuable information concerning the effects of selected loads on combative movement.
