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 across two consecutive days of work.
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.

Treatments tested in this trial
Standard work pace
BehavioralOn two consecutive days, participants will work at a standard pace of one box per minute during the box carrying protocol
Additional rest breaks
BehavioralOn two consecutive days, participants will work at the standard work pace during the box carrying protocol and have superimposed 5 minutes of rest every 30 minutes.
