Impact of Physical Exertion in the Workplace on Muscle Fatigue, Tissue Properties and Proprioception of Older Workers: A Feasibility Study


This research activity aims to determine the feasibility of measuring the impact of physical exertion in a work day on the development of muscle fatigue, tissue properties and proprioception of workers aged 55 and over, as well as of workers under the age of 40. Proprioception is the neural information transmitted to the brain that regulates posture and body movements.

Despite the significant increase in the number of older workers and epidemiological surveys of this population, there is little scientific evidence on the impact of the physical and physiological changes that accompany aging on workplace injuries.

Because of their experience and the adoption of precautionary strategies, these workers are less likely to be injured on the job. However, the injuries they suffer may be more severe. In fact, this is one of the findings of an IRSST report published in 2012.
