Protocol summary
Study aim
The aim of the present study is to investigate the effect of chlorella vulgaris algae supplementation, HIIT exercises and their combination on the serum levels of PGC-1α, FGF21, SIRT1, nutritional status, body composition and aerobic power in young women with overweight and obesity.
Design
Randomized clinical trial, double blinded with four parallel groups
Settings and conduct
The intervention will be conducted at gym of the University of Medical Sciences and Faculty of Physical Education of Tabriz University for 8 weeks. Supplements and placebo will be coded by the person in charge, and the main investigators and patients will be blind to the type of supplement used.
Participants/Inclusion and exclusion criteria
44 participants with BMI between 25 and 34.9 will be included in the study. Individual consent and inclination to cooperation is an inclusion criteria Bone and joint problems will not be included.
Intervention groups
Intervention group 1: Supplementation of Chlorella Vulgaris from the Green Iranian's future Company (900 mg / day, 300 mg) and HIIT performance (three sessions per week for 60 minutes).
Intervention group 2: HIIT performance (similar protocol) exercises and receive the placebo from Iranian's Green future.
Intervention group 3: Receive chlorella vulgaris (900 mg / day, 300 mg).
Control group: Will receive the same placebo with the same protocol.
Main outcome variables
Time to get tired with Bruce test; Maximum oxygen consumption; Aerobic power ; Anthropometric indices and body composition (FM, FFM, BW); Basal Metabolic Rate (BMR); Blood pressure; Heart rate; Food intake (energy, carbohydrate, protein and fat). ); Physical activity; fasting blood glucose, lipid profile (TC, HDL-C, TG, LDL-C), serum level of Sirtuin1(SIRT-1), Fibroblast Growth Factor 21 (FGF21) and Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α).

Blinding (investigator's opinion)
Double blinded
Blinding description
In this study, the main investigators (including the student, and her supervisor and adviser professors) as well as the patients will be blinded to the type of the supplement (chlorella vulgaris or placebo) received by each group. The person responsible for preparing the supplement boxes(who is completely unrelated to the study) will be asked to assign a three digit code to each of the two powders (chlorella vulgaris and placebo), and keep the codes for himself until the end of the study and data analyses.

Primary outcomes
1
Description
Time to reach the fatigue
Timepoint
Baseline and 8 weeks after intervention
Method of measurement
The time to reach the fatigue or maximum power of a person is done using the Bruce test with the help of treadmill. The test results are reported in minutes and indicate the cardiovascular power.
2
Description
VO2 maximum or aerobic power
Timepoint
Baseline and 8 weeks after intervention
Method of measurement
Maximum oxygen consumption (VO2max) or maximum aerobic power is the highest oxygen content used in extreme exercise and is the most important aerobic fitness index, cardiovascular health and endurance ability. VO2max can be measured by direct and indirect methods. Here using the indirect method, the Bruce test on the treadmill, which measures the VO2max from the time of performance or the maximum power output.

Description
Anthropometric measures
Timepoint
Baseline and 8 weeks after intervention
Method of measurement
Measurement of height and weight without shoes and with minimum clothes on, by Seca stadiometer and scale, respectively. Measurement of waist and hip circumferences by a tape measure. Calculation of waist to hip ratio (WHR) by dividing waist circumference by hip circumference, and body mass index (BMI) by dividing weight (Kg) by height squared (m2).
