Study aim
-
The aim of this study was to evaluate the effect of eight weeks of intense and continuous intermittent training on galactin 3, growth differentiating factor 15, NT-proBNP and interleukin 6 in overweight men.
-
Design
-
In this study, 36 overweight men participated voluntarily who were randomly divided into three groups of control, continuous training and high intensity interval training.
-
Settings and conduct
-
The present study is conducted in Ahar city. Training protocols run for three sessions per week for eight weeks. Blood samples are taken from the subjects in two stages before the test and after the test.
-
Participants/Inclusion and exclusion criteria
-
Criteria for selection of individuals, being male, age range between 23 to 28 years and body mass index between 25 to 30, Lack of cardiovascular, liver, kidney and pulmonary disease and serious physical and orthopedic injuries, as well as lack of regular exercise in the year leading to the study.

Intervention groups
-
High intensity interval training group and continuous training group and control group.The intense interval training group first warmed up on the treadmill for 10 minutes with an intensity of 40-50% of the maximum heart rate, and then the main program, which included 4 repetitions of 4 minutes of activity, was performed. Between each workout was a 3-minute active rest session with an intensity of 50-40 percent of the maximum heart rate. The moderate-intensity continuous training protocol included 4 minutes of warm-up with 40 to 50 percent of maximum heart rate and 40 minutes of running with 60 to 70 percent of heart rate. Finally, 3 minutes of cooling with 50 percent intensity is included. The control group did not have any training during this period.

Main outcome variables
