“…Studies that used such methods demonstrated that normal aging alters the performance of goal directed movements, with a decrease in movement speed (Ren et al, 2013;Welford, 1988), longer movement times and deceleration phases (Goggin & Stelmach, 1990;Roy, Weir, Desjardins-Denault, & Winchester, 1999;Shiffman, 1992;Warabi, Noda, & Kato, 1986), a reduced strength (Shiffman, 1992;Voorbij & Steenbekkers, 2001), as well as a general slowing down of the movement (Welford, 1988). However, this impoverishment of the movements is not always observed; several studies reported similar performance for young and elderly adults, both in terms of reaction times and movement speed (Carnahan, Vandervoort, & Swanson, 1998;Riecker et al, 2006).…”

“…Clinically, researchers have been attempting to link grip strength to overall body strength and general health (Onder et al, 2005, Rantanen et al, 1999, Voorbij & Steenbekkers, 2001). In addition to simply measuring grip force, this dynamometer could be used to non-invasively evaluate injury, disease or age related deficits in maintenance and control of musculoskeletal structures.…”

Objective This article describes the development and application of a novel multi-axis hand dynamometer for quantifying two-dimensional grip force magnitude and direction in the flexion-extension plane of the fingers. Methods A three-beam reconfigurable form dynamometer, containing two active beams for measuring orthogonal forces and moments regardless of point of force application, was designed, fabricated and tested. Maximum grip exertions were evaluated for sixteen subjects gripping cylindrical handles varying in diameter. Results Mean grip force magnitudes were 231 N (SD=67.7 N), 236 N (72.9 N), 208 N (72.5 N), and 158 N (45.7 N) for 3.81 cm, 5.08 cm, 6.35 cm and 7.62 cm diameter handles, respectively. Grip force direction rotated clockwise and the centre of pressure moved upward along the handle as handle diameter increased. Conclusions Given that the multi-axis dynamometer simultaneously measures planar grip force magnitude and direction, and centre of pressure along the handle, this novel sensor design provides more grip force characteristics than current sensor designs that would improve evaluation of grip characteristics and model-driven calculations of musculoskeletal forces from dynamometer data.

“…Using slightly different age group definitions, Peebles and Norris (2003) showed that the average strength pulling on a horizontal bar was 456.98 N among the 61-70 year-olds, and was 383.52 N among the 51-60 year-olds. Voorbij and Steenbekkers (2001) presented the strength prediction curves for various exertions using age as a predictor. For the one-handed pulling strength, the age 55-59 group outperformed the age 50-54 group.…”

The aging workforce, increase in obesity, and lack of exercise and physical activity are changing the landscape of work environments in the industrialized world. The goal of this panel is to make ergonomics and safety professionals aware of the importance of examining health and wellness issues, aging, obesity, and other modifiable health risks pertaining to occupational health. The first of seven presentations will cover an evidence based wellness continuum that describes specific factors that can motivate healthy work environments. The second presentation discusses the challenges and implications of the aging workforce with emphasis on the role of ergonomics in maintaining health, wellness and working contributions of the aging workforce. In general, muscle mass and muscle strength decrease with age, however the third presentation examines if such age-associated changes are evident during one-handed isometric pulling. Stratifying injury risk in overweight and obese populations is still a challenging endeavor. The fourth presentation demonstrates the biomechanical consequences of gait (a)symmetry due to being overweight and the risk of falling. There is an increasing evidence of obesity influencing every organ system adversely in the human body, including the brain. The fifth presentation examines the association between work performance of obese and non-obese individuals during incremental repetitive lifting and change in their cerebral hemodynamics and cardiorespiratory responses. An interaction between aging and obesity in addressing the risk for involvement in a motor vehicle crash is discussed in the sixth presentation. The final presentation focuses on understanding the integrated efforts of physiological systems such as respiratory, cardiovascular, and skeletal muscle within the context of aging, obesity and physical activity.
