简要总结
This study aims to assess current health and fitness of law enforcement workers in various roles, and to evaluate the impact of an exercise intervention on markers on physical and mental wellbeing in this population.
The intervention will consist of an exercise programme specifically targeted at improving, physical fitness and reducing musculoskeletal pain. Participants will be randomised to three groups: a face to face intervention group, an online intervention group an a control group.
Self-reported physical health, musculoskeletal complaints, quality of sleep and occupational stress will be measured via questionnaires. Pre and post measures of fitness will be measured via functional strength testing and a cardiopulmonary exercise test. Pre and post cognitive function will be measured via computer-based cognitive tests and brain functional near-infrared spectroscopy (fNIRS). Systemic inflammation will be measured via hsCRP. Risk of typeII diabetes will be measured via HbA1c. Daily physical activity and quality of sleep will be measured via accelerometry and heart rate telemetry.
It is hypothesised that, upon completion of the programme, there will be an improvement in cardiovascular fitness and physical strength, reduced musculoskeletal pain, improved cognitive readiness and improved overall mental health and wellbeing.
详细描述
Randomisation Participants will be stratified by shift pattern and by role, and will be randomised to one of three intervention arms using permuted blocks of 3 and 6.
Self-reported information After the consent forms and PAR-Q have been signed, an Operational Police Stress Questionnaire (PSQ-Op), Impact of Events Scale (IES-R), a Leeds Sleep Evaluation (LSE) and an overall health and injury questionnaire (Nordic scale) will be sent to the officers via email using Gorilla software in December 2019.
Participants will be interviewed on the quality of their dietary intake. Trained nutrition research students will collect responses to a Food Frequency Questionnaire (FFQ) in a face to face interview.
Wearables Participants will be given wearable devices to measure their levels of physical activity during an 8-day period (full on and off shift cycle) before the intervention: the heart rate of each participant will be monitored via a Polar heart rate monitor and movement will be measured via an accelerometer worn on the non-dominant wrist (Actigraph, Pensacola, USA). Levels of physical activity, quality of sleep and heart rate variability will be processed as anonymised data on a computer. Participants will be asked to log the quality of their sleep every time they wake up from a long sleep via a Pittsburgh Sleep Quality Index (PSQI). No individuals other than the researchers will have access to the data from the wearable devices. The data will be downloaded from the device and stored in a password-protected file, on an encrypted, password-protected UCL computer in a locked cabinet. After downloading the data to the computer, the wearable device will be formatted.
Oral tests Participant oral health will be assessed on site at the respective stations in January. Oral inflammation has been shown to affect systemic health with cross-sectional evidence suggesting a negative effect on physical activity in Brazilian police. Oral health will be assessed using validated outcome measures routinely employed in both NHS dental practice and research, including: the visual assessment of inflammation of the gum edge and measurement of the depth of the gum pocket (mm) following gentle probing with a calibrated blunt probe; and tooth decay screening assessed through standard clinical methods. Together, these assessments take approximately 15 minutes.

结局指标
主要结局
Change in upper body strength endurance (push)
时间窗: Change from baseline after 8 weeks
Numbers of pushups performed in one minute with good form (eg. not dipping the hips and using full range of motion)
Changes in musculoskeletal pain: measured via the Nordic Scale
时间窗: Change from baseline after 8 weeks
Complaints of musculoskeletal pain, collected via a Nordic Scale. The scale runs from 0-10, where 0 is no pain at all and 10 is worst imaginable pain.
Change in leg strength, measured via the Triple Hop test
时间窗: Change from baseline after 8 weeks
Participants perform three hops on one leg. The total distance (cm) of the three hops is recorded. The test is repeated for both legs.
Change in lower limb power
时间窗: Change from baseline after 8 weeks
Participants perform a counter-movement jump on a jump mat (Chronojump). Power (Watts) is recorded.
Change in Cardiovascular fitness
时间窗: Change from baseline after 8 weeks
measured via CPET test
Change in upper body strength endurance (pull)
时间窗: Change from baseline after 8 weeks
Numbers of inverted rows performed in one minute with good form (eg. not dipping the hips and using full range of motion)
Change in hand grip strength
时间窗: Change from baseline after 8 weeks
Hand grip strength (Newtons) is measured with a hand-held dynamometer.
