Thanks to completing eight weeks of prehabilitation exercises, Angie exceeds the physical demands of her role, while Bella meets the demands of hers. On any given typical day, both Angie and Bella are suitably matched to their roles and therefore have low risk of pain or injury. Now, imagine it’s the Monday following a weekend-long netball tournament, which was physically exhausting. Angie and Bella’s personal physical capacity is likely decreased. Due to Angie having exceeded the capacity demands of her role, she has more wiggle room in terms of physical performance, when compared to Bella who may now be at risk of her personal physical capacity being beneath the safe requirement for her medium rated tasks.
A similar effect happens when personal capacity is unaffected, but there is a spike in the physical demands of the role. For example, when the automatic box maker jams, and the workers need to hand-make each cardboard box that day. Or, when another member of staff calls in sick and the rest of the team’s workload increases to cover their work.
