Acme industries manufactures microwave ovens with a production workforce of 450 full-time workers. the process includes using pneumatic screwdrivers and drills and manually lifting boxes weighing up to 35 pounds from a height of 24" to a height of 36". over the past year, there have been 35 cases of carpal tunnel syndrome and 15 cases of lower back strain reported. there were 850,000 total work hours at the facility for the year. calculate the combined incidence rate of msds and ctds for the facility for each 100 full-time workers per year. compare the rate to the industry rate of 1.5/100 workers/year. do you believe the incidence rate for acme industries is a problem?

Warm up, exercise, cool down

Muscles in the body us with a lot of things for example, if i wanted to lift a heavy box and had no muscle i would just collapse where i was because of the fact muscles hold us together. overall they are 650 muscle in the human body, all of them have different purposes and ways to keep us together. there are three types of muscle in the body skeletal, smooth, and cardiac muscle. skeletal muscle are attached to the bone and with movement. smooth muscle, this is found in the wall of our organs, such as our stomach, this muscle with movement   as well, without this muscle, we would only be allowed to eat small amounts. the cardiac muscle is the heart muscle and probably the most important one. these are only found in the walls of the heart and the heart pump blood to the other parts of your body. we have two different types of muscle fibers, slow twitch and fast twitch. slow twitch muscles enable long-endurance feats such as distance running. fast twitch fatigue faster but are used in powerful bursts of movements like sprinting. there are three different types of muscle contractions concentric, eccentric, isometric. concentric contraction causes muscles to shorten, thereby generating force.   eccentric contractions cause muscles to elongate in response to a greater opposing force. isometric contractions generate force without changing the length of the muscle.: //athleticquickness.com/muscle-contraction-types-part-1/
