MH collected the contact data, implemented and ran the simulations, performed analysis and contributed text to the paper, NO provided the initial experimental and simulation design and contributed to the paper, KS provided the initial data collection design, performed analysis and contributed to writing of the paper.
Each subject completed a familiarization session at the start of the season during the initial data collection and functional movement assessment, consisting of five trials of each of the three tests.

Any uncertainties in data entry were resolved through consensus after reviewing the initial data collection forms and, if necessary, discussing the data with the interviewer who conducted that interview.
Those who agreed to participate in the "Invece.Ab" study were enrolled in a cross-sectional assessment and will be contacted two and four years after the initial data collection to participate in the longitudinal survey.
Mandatory variables included on the initial data collection form and used for this study were: age, gender, race (black non-Hispanic, white non-Hispanic), type of practice, size of the largest polyp detected at colonoscopy, number of polyps (single versus ≥ 2), any family history of colorectal cancer (positive, negative) and polyp location defined as proximal or distal to the splenic flexure.
During the initial data collection phase, inclinometer posture information was collected over the full duration of each shift at 32 Hz.
23 28 Statistics Sweden sent out the VAWI and NorAQ between November 2009 and January 2010 to 20% (n=92) of the respondents from the initial data collection.
NH was also responsible for the initial data collection at the GNC (Zambia) and NMC and coordinated the writing of this paper.
The final data linkage exercises took place on 8 February 2013 (ONS) and 26 March 2013 (NISRA), approximately 3 years after the initial data collection.
