“…No evidence was found of either muscular fatigue over time or differences in muscular fatigue or back muscle co-contraction between footwear, which is reflective of similar previous literature (Antle et al, 2013;Coenen et al, 2017;Gregory & Callaghan, 2008). Evidence of fatigue over time in the calf muscles during prolonged standing has been shown using muscle twitch force (Brownie & Martin, 2015;Garcia et al, 2015), although these changes were recorded over 5 hours and did not differ between floor surfaces. Footwear type has previously been shown to determine if muscular fatigue occurs, with increased instability and thus more dynamic standing thought to be protective (Karimi et al, 2016).…”

“…Although muscular factors are thought to impact discomfort, results from studies assessing lower limb fatigue using electromyography (EMG) are inconsistent (Antle et al, 2013;Coenen et al, 2017;Gregory & Callaghan, 2008;Brownie & Martin, 2015;Garcia, Laubli, & Martin, 2015). There is some evidence to suggest a role of co-contraction of bilateral lower back muscles in the development of lower back pain (Nelson-Wong, Gregory, Winter, & Callaghan, 2008;) but this is still limited (Coenen et al, 2017).…”

Prolonged occupational standing: the impact of time and footwear

Prolonged occupational standing is strongly related to musculoskeletal disorders. Despite being the main external load bearing interface between the floor and musculoskeletal system, and easy to manipulate, footwear is often ignored as an intervention for standing related disorders. This study aimed to record the effect of prolonged standing on the body and determine the impact of footwear material. Two pairs of surgical clogs were tested, varying only in material hardness. Participants (n=12) undertook 3 hours of standing in each shoe whilst they completed a repetitive series of simulated work tasks. Biomechanical and subjective data were recorded at the start, end and every 30 minutes during the three hours of standing. There was an increase in discomfort of the low back and all lower extremity regions alongside an increase in calf circumference, selected kinematic and kinetic variables, and changes in plantar pressure distribution over the three hours. Altering the footwear material impacted on low back discomfort and plantar pressures. Shoe preference varied amongst individuals, but was consistently associated with an increased medial midfoot contact area. Overall, this study has demonstrated the effect of prolonged standing on the body, has shown footwear impacts both subjective and biomechanical measures and provides information regarding individual differences and footwear preferences.

“…Prolonged flexion during sitting has been proposed to redistribute the nucleus within the annulus (26) or increase lumbar spine stiffness (27). Prolonged standing may also lead to pain from muscle fatigue (28). Further hypotheses imply reduced oxygenation in lumbar extensor musculature (29) and increased weight as result of inactivity in sitting (30,31) as possible mechanisms.…”

“…Muscle fatigue was quantified using electrically induced muscle twitches (MTF) and objectively assessed using postural stability analysis combined with subjective evaluation of discomfort. Both MTF and subjective evaluation demonstrate significant fatigue after standing work persisting beyond 30 minutes at the end of the work day [28].…”

The human spine is like a precious strand of pearls linked together by ligaments, muscles and connective tissues."The 21st Century Upright Woman was originally published by the San Francisco Bay view Newspaper on April 10, 2010, as an essay exploring the relationship between the anatomy and evolutionary anthropology of the spine, low back pain, lumbar degenerative disc disease and the spine health of the modern woman. It was inspired by a presentation and workshop on Women's Health I led that month at the University of San Francisco's Mission Bay Campus.This review details the conclusive body of anthropological evidence linking human evolution and the bipedal spine to the Global Pandemic of low back pain and lumbar degenerative disc disease.Occupational injury, strain and sports overuse, morbid obesity, poor posture and spinal malalignments, extended sitting, standing, sedentary lifestyles and poor nutrition contribute to the disabling impact of this most ancient-most common-human affliction.A mounting body of evidence based research supports the simple role of weight loss, lifestyle change, occupational impact mitigation and exercise in the treatment and prevention of chronic low back pain.

Long-Term Muscle Fatigue After Standing Work

Abstract: The present results suggest that occupational activities requiring prolonged standing are likely to contribute to lower-extremity and/or back disorders.
