| Some genetic factors may influence body composition, such as PPARγ and UCP2. PPARγ
plays an important role in body fat distribution. The objective of the present study is
to determine the effects of omega3 fatty acids on the gene expression of PPARγ and
UCP2, levels of blood lipid profile, fat mass, and fat-free mass, and appetite.
Elite male athlete volunteers of up to 36 subjects were invited to participate in this RCT.
Following a public announcement, volunteers were recruited from gyms, teams, and
sports medicine boards in Tabriz, Iran. Gene’s expression of PPARγ and UCP2, serum
levels of blood lipid profile, fat mass, and fat-free mass was collected. Data collection
time points include baseline in addition to 3 weeks follow up. The study was approved
by the Ethics Committee of the Tabriz University Medical of Sciences (IR.TBZMED.
REC.1398.782) in October 2019 and was registered with the Iranian Registry of Clinical
Trials: 20190625044008N1 on December 19, 2019.
Recruitment began in July and concluded in December 2019. As of August 19, 2019,
we have screened 373 volunteers. 36 were enrolled. Baseline measurements of
participants were collected. After three-week of intervention, end study measurements
of participants were collected. The results are expected to be released in 2021.
Participants have a median age of 21.86 (±3.15). The finding of this study showed
Results showed PPARγ mRNA levels, and UCP2 mRNA and protein levels increased in
the omega3 group (p < 0.05), as did REE (p < 0.05). Also, differences in the sensation of
hunger or satiety were significant (p < 0.05).
This study could result in the effects of omega-3 fatty acids on PPARγ, and UCP2
expressions, blood lipid profiles and body composition. In addition, the results of this
trial can be used as baseline information for conducting further clinical and sport
nutrition studies.
