22. maj 2026 opdateret af: Konstantina Karatrantou, University of Thessaly

A Combined Workplace Intervention Including Exercise and Nutrition for Health Promotion in Obese Office Workers: a Randomized Controlled Study

The main objective of this study is to investigate the efficacy of a 6-month workplace combined (exercise and nutrition) intervention in obese office workers, using a randomized controlled study. An additional objective of this study is to evaluate the individual responses per participant following the program.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Intervention group
The IG will participate in a daily supervised 6-month workplace program (during working hours) including: a. exercise (flexibility, balance, strength, aerobic), and b. counseling and educational activities for healthy diet and hydration.
Andet: Workplace combined (exercise and nutrition) intervention
The IG will participate in a supervised 6-month combined intervention program (exercise and nutrition), which will take place inside the workplace settings during working hours. In more detail, the IG will participate, every working day (5 days/week), in a 6-month supervised combined chair-based exercise program (120 training sessions; 25-40 min/day), including chair based seated and chair-assisted standing exercises to improve flexibility, balance, strength and aerobic capacity. Except exercise, the intervention program consisted of weekly counseling and educational activities in healthy diet and proper hydration using presentations, leaflets, individual and group sessions with nutritionist, use of applications for proper hydration, use of goal-setting cards for healthy options
Ingen indgriben: Control group
The CG did not participate in any intervention.

Hvad måler undersøgelsen?

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Body fat
Tidsramme: Baseline and 6 months
Body fat (BF): BF% will be assessed using the bioelectrical impedance method (Maltron 900).
Baseline and 6 months
Body circumferences
Tidsramme: Baseline and 6 months
The waist and hip circumferences will be measured using an ergonomic circumference measuring tape (Seca 201).
Baseline and 6 months
Blood pressure
Tidsramme: Baseline and 6 months
Systolic and diastolic blood pressure will be measured, using an electronic upper arm blood pressure monitor (A&D-UA-851).
Baseline and 6 months
Respiratory function
Tidsramme: Baseline and 6 months
Forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1) will be measured, using a portable spirometer (Micro, Medical, Micro).
Baseline and 6 months
Lipidemic profile
Tidsramme: Baseline and 6 months
A blood sample will be obtained after overnight fasting (12 h), as previously described [37]. Total cholesterol, high-density lipoprotein (HDL) and triglycerides will be determined using a biochemical analyzer (Clinical Chemistry Analyzer Z 1145; Zafiropoulos Diagnostica S.A., Koropi, Greece), and low-density lipoprotein (LDL) will be calculated using the Friedewald equation.
Baseline and 6 months
Lower body flexibility:
Tidsramme: Baseline and 6 months
The sit-and-reach test will be performed using a Flex-Tester box (Novel Products Inc., Rockton, IL, USA).
Baseline and 6 months
Static balance
Tidsramme: Baseline and 6 months
The single-limb stance test (with eyes opened) was performed, as previously described by Rinne et al.
Baseline and 6 months
Dynamic balance:
Tidsramme: Baseline and 6 months
The timed up-and-go test was performed, as previously described by Rikli and Jones.
Baseline and 6 months
Handgrip strength
Tidsramme: Baseline and 6 months
Maximal isometric handgrip strength will be assessed using a portable hydraulic dynamometer (Jamar 5030J1, Horsham, USA).
Baseline and 6 months
Aerobic capacity:
Tidsramme: Baseline and 6 months
The YMCA 3 min step test was used, which will be performed following the metronome cadence (96 beats per minute; 4 steps per cycle). The participants' HR will be measured 1 min following the termination of the step test.
Baseline and 6 months
Adherence to the Mediterranean diet
Tidsramme: Baseline and 6 months
The adherence to the Mediterranean diet will be assessed before and after the 6-month period using the specific Mediterranean Diet Score (range of total score: 0-55) [34-35]. The MedDietScore measures the weekly consumption of the following 9 food groups: non-refined cereals (whole grain bread and pasta, brown rice, etc), fruit, vegetables, legumes, potatoes, fish, red meat and products, poultry, full fat dairy products (like cheese, yoghurt, milk), as well as olive oil and alcohol intake [35].
