Beskrivelse
Inclusion Criteria:
- middle age (35-59 years)
- male
- self-report working full-time in the food service industry (≥30 hours/week)
- self-report predominantly completing light intensity activity job responsibilities (≥75% work time walking, light movement, or standing)
Exclusion Criteria:
- Resting blood pressure of ≥150 mmHg systolic and/or ≥95 mmHg diastolic
- currently taking medications that are known to affect blood pressure or heart rate (e.g. Beta-blockers, ACE inhibitors, etc.)
- greater than low risk to participate in physical activity as determined by PAR-Q (answer of yes to any of the 7 physical activity readiness questionnaire questions)
- report working a second job in addition to their primary full-time job
- report working overnight shifts (10pm-6am)
- reported physical dysfunction (inability to walk 2 city blocks or climb 2 flights of stairs)
- inability to complete the sub-maximal exercise test to completion (80% age-predicted heart rate maximum)
- Currently being treated for a serious medical condition such as kidney disease, liver disease, cancer, or heart disease.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
24-hour Ambulatory Systolic Blood Pressure
Tidsramme: 24 hours
|
We will calculate the average systolic blood pressure over a 24-hour period on two separate days (workdays versus non-workdays).
|
24 hours
|
|
Nocturnal Heart Rate Variability, RMSSD
Tidsramme: approximately 8 hours (sleep time)
|
We will calculate the average heart rate variability during each night's sleep for a total of one week.
The specific HRV variable presented is root mean square successive differences (RMSSD).
|
approximately 8 hours (sleep time)
|
|
Physical Activity Pattern. Steps Per Day
Tidsramme: 1 week
|
This physical activity metric of steps per day was calculated as average number of steps during each day type (work versus non-workdays) throughout one week
|
1 week
|
|
Nocturnal Heart Rate Variability, SDNN
Tidsramme: approximately 8 hours (sleep time)
|
We will calculate the average heart rate variability during each night's sleep for a total of one week.
The specific HRV variable presented is standard deviation of the normal to normal RR intervals (SDNN).
|
approximately 8 hours (sleep time)
|
|
Nocturnal Heart Rate Variability, LF
Tidsramme: approximately 8 hours (sleep time)
|
We will calculate the average heart rate variability during each night's sleep for a total of one week.
The specific HRV variable presented is low frequency power (LF).
|
approximately 8 hours (sleep time)
|
|
Nocturnal Heart Rate Variability, HF
Tidsramme: approximately 8 hours (sleep time)
|
We will calculate the average heart rate variability during each night's sleep for a total of one week.
The specific HRV variable presented is high frequency power (HF).
|
approximately 8 hours (sleep time)
|
|
Physical Activity Pattern. MVPA
Tidsramme: 1 week
|
This physical activity metric of minutes of moderate to vigorous physical activity was calculated as average minutes during each day type (work versus non-workdays) throughout one week
|
1 week
|
|
Physical Activity Pattern. LPA
Tidsramme: 1 week
|
This physical activity metric of minutes of light physical activity was calculated as average minutes during each day type (work versus non-workdays) throughout one week
|
1 week
|
|
Physical Activity Pattern. Sedentary
Tidsramme: 1 week
|
This physical activity metric of minutes of sedentary time was calculated as average minutes during each day type (work versus non-workdays) throughout one week
|
1 week
|
|
Physical Activity Pattern. Upright
Tidsramme: 1 week
|
This physical activity metric of minutes of upright time was calculated as average minutes during each day type (work versus non-workdays) throughout one week
|
1 week
|
|
24-hour Ambulatory Diastolic Blood Pressure
Tidsramme: 24 hours
|
We will calculate the average diastolic blood pressure over a 24-hour period on two separate days (workdays versus non-workdays).
