Brief Summary

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.

Outcome Measures

Primary Outcomes (7)

• Changes in musculoskeletal pain: measured via the Nordic Scale

  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 from baseline after 8 weeks

• Change in upper body strength endurance (push)

  Numbers of pushups performed in one minute with good form (eg. not dipping the hips and using full range of motion)

  Change from baseline after 8 weeks

• Change in upper body strength endurance (pull)

  Numbers of inverted rows performed in one minute with good form (eg. not dipping the hips and using full range of motion)

  Change from baseline after 8 weeks

• Change in leg strength, measured via the Triple Hop test

  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 from baseline after 8 weeks

• Change in lower limb power

  Participants perform a counter-movement jump on a jump mat (Chronojump). Power (Watts) is recorded.

  Change from baseline after 8 weeks

• Change in hand grip strength

  Hand grip strength (Newtons) is measured with a hand-held dynamometer.

  Change from baseline after 8 weeks

• Change in Cardiovascular fitness

  measured via CPET test

  Change from baseline after 8 weeks

Secondary Outcomes (18)

• Change in simple reaction time after maximal exercise

  Change from baseline after a single bout of maximal exercise (CPET)

• Change in simple reaction time after an exercise intervention

  Change from baseline after 8 weeks

• Change in Motor Inhibition after maximal exercise

  Change from baseline after a single bout of maximal exercise (CPET)

• Change in Motor Inhibition after an exercise intervention

  Change from baseline after 8 weeks

• Change in source memory after maximal exercise

  Change from baseline after a single bout of maximal exercise (CPET)

Study Arms (3)

Face to face exercise intervention

EXPERIMENTAL

Participants will participate in face to face exercise programme delivered by a strength and conditioning coach. Sessions will last 1 hour, 3 times a week, and will be offered at the work place. The coach will register attendance in order to monitor compliance.

Behavioral: Exercise

Online exercise intervention

ACTIVE COMPARATOR

Participants will be given the same training programme as the face to face group, but via an online app. Sessions should last 1 hour and should be completed 3 times a week. Participants will be asked to post a "work-out picture" on the social platform of the app as proof that they completed their session.

Behavioral: Exercise

Control

NO INTERVENTION

This group will undergo all pre and post tests, but will not receive an intervention.

Interventions

Exercise BEHAVIORAL

Functional strength training, 1 hour, 3 times a week.

Face to face exercise intervention; Online exercise intervention
