Brief summary
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.
Interventions
OTHERWorkplace 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

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Body fat | Baseline and 6 months | Body fat (BF): BF% will be assessed using the bioelectrical impedance method (Maltron 900). |
| Body circumferences | Baseline and 6 months | The waist and hip circumferences will be measured using an ergonomic circumference measuring tape (Seca 201). |
| Blood pressure | Baseline and 6 months | Systolic and diastolic blood pressure will be measured, using an electronic upper arm blood pressure monitor (A\&D-UA-851). |
| Respiratory function | 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). |
| Lipidemic profile | 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. |
| Lower body flexibility: | Baseline and 6 months | The sit-and-reach test will be performed using a Flex-Tester box (Novel Products Inc., Rockton, IL, USA). |
| Static balance | Baseline and 6 months | The single-limb stance test (with eyes opened) was performed, as previously described by Rinne et al. |
| Dynamic balance: | Baseline and 6 months | The timed up-and-go test was performed, as previously described by Rikli and Jones. |
| Handgrip strength | Baseline and 6 months | Maximal isometric handgrip strength will be assessed using a portable hydraulic dynamometer (Jamar 5030J1, Horsham, USA). |
| Aerobic capacity: | 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. |
| Adherence to the Mediterranean diet | 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 \[35\]. |
