The purposes of this study are to examine:

• The temporal associations between acute psychosocial stress, sleepiness, and PA
• The association between chronic psychosocial stress and sleep quality and cardiovascular risk in Colorado firefighters
• The moderating effects of PA and CRF on the associations between chronic stress and sleep quality on cardiovascular risk.

We hypothesize that:

• Greater acute psychosocial stress will predict lesser subsequent physical activity participation and vice-versa
• That greater sleepiness will predict greater subsequent stress and lesser subsequent physical activity participation
• Higher levels of stress and worse sleep-related outcomes will be associated with an elevated cardiovascular risk
• Higher levels of physical activity participation and greater CRF will be associated with lower cardiovascular risk
• Physical activity participation and CRF will moderate the associations between stress, sleep, and cardiovascular risk.

Inclusion:

• Full-time, career firefighters on active duty who work 24 or 48 hour shifts and who work in fire departments that participate in CSU's Firefighter Testing Program
• Firefighters must also have a smartphone and be willing to use the smartphone to download a free application (Ilumivu) to complete the EMA protocol
• Willing to comply with study protocol, including the surveys, wearing the activPAL and Actiwatch devices, and completing the ecological momentary assessment questions via the application downloaded to their smartphone, and sharing their Firefighter Testing Program data as part of the research study.

Our current studies investigate the foot-ground interaction as well as the use of functional movement assessments to reduce injury risk in athletic populations. We need participants that are young-healthy adults that regularly play ground-based sports (e.g. soccer, football, rugby, ultimate frisbee) and are willing to come in and perform maximum effort running, jumping, cutting, and pivoting.

Mechanical properties of flooring surfaces, specifically artificial turf, are tested with a variety of industry standard devices. Effects of environment and use on infill properties are not well understood. We are exploring potential changes. Existing equipment is often inconsistent and not representative of athletes. We are designing the next generation of testing equipment.
