Ergonomic effects of load carriage on energy cost of gradient walking.

Ergonomic effects of load carriage on the upper and lower back on metabolic energy cost of walking

Ergonomic effects of load carriage on the upper and lower back on metabolic energy cost of walking.

We examined the effects of load carriage position on the energy cost of walking defined as the ratio of the 2-min steady-state oxygen consumption to the speed and economical speed. Fourteen healthy men walked on a treadmill at various speeds without and with load on the lower and upper back, which corresponded to 15% of their body mass. The energy cost of walking significantly decreased during ...

The Effects of Hand-held Load Carriage Techniques on Lower Extremity Continuous Relative Phase Variability

INTRODUCTION Despite the frequency of hand-held load carriage in many industrial settings, most research to date has focused primarily on packs as the means of load carriage. The Mover’s Assistive Device (MAD), developed in 2008 at Queen’s University in conjunction with local moving companies, is an on-body ergonomic aid designed to reduce musculoskeletal effort during hand-held load carriage. ...

Enegry Cost of Heavy Load Carriage and Prolonged Walking in Rotc Collegiate Participants

ENEGRY COST OF HEAVY LOAD CARRIAGE AND PROLONGED WALKING IN ROTC COLLEGIATE PARTICIPANTS By Sara Marie Krajewski April, 2014 Director of Thesis: Dr. Laurel Wentz Major Department: Kinesiology The load military service members carry while marching has increased throughout history, and the military routinely uses rucksacks that range in weight from 22-68 kilograms, depending on the type of missio...

RESPONSES OF OXYGEN CONSUMPTION, HEART RATE AND PERCEIVED EXERTION TO CRUTCH WALKING: A COMPARISON BE TWEEN PAR APLEGIC AND ABLE-BODIED SUBJECTS

In this study, 10 normal volunteers and 5 sports-trained paraplegics with lesions between T6 and L2 were studied whilst walking with axillary crutches and knee-anlde-foot orthoses. All subjects walked at their preferred speed on a figureof- eight track. Normal subjects also walked at slower and faster speeds. Oxygen consumption, heart rate and rating of perceived exertion were measured. In...
