About this trial
The goal of this project is to compare different ways to schedule a workday to see if older workers should follow a specific work protocol to reduce strain on the heart and muscles.
Participants will come to the lab a total of six times. During four of the visits participants will complete a box carrying task, simulating unloading a delivery truck. This will take place in a hot and humid room to simulate being outdoors during the summer.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Healthy individuals
18-29 years old and 40-65 years old
Completes at least 120 minutes of moderate to vigorous physical activity each week for at least the past 4 weeks
Resistance trained or have recently held a job involving box carrying or a similar task
Disqualifiers
History of cardiovascular, metabolic, respiratory, neural, or renal disease
Hypertensive (systolic blood pressure > 139 mmHg or diastolic blood pressure > 89 mmHg) or tachycardic (resting heart rate > 100 bpm) during the screening visit
Current nicotine use or previous use within the past 6 months
Current of previous musculoskeletal injury limiting physical activity
Trial design
Design model
Crossover
Treatments tested in this trial
Standard work pace
BehavioralParticipants will work at a standard pace of one box per minute during the box carrying protocol
Reduced-pace work
BehavioralParticipants will work at a slower pace than the standard work pace of the box carrying protocol
Increased-pace work
BehavioralParticipants will work at a faster pace than the standard work pace of the box carrying protocol
Additional rest breaks
BehavioralParticipants will work at the standard work pace during the box carrying protocol and have superimposed 5 minutes of rest every 30 minutes.
