Protocol summary

Study aim
The main aim of the present study is to compare the effect of a selected resistance and aerobic training course on the expression of miRNA-126 and miRNA-221 and the lipid profile of overweight/obese women.
Design
This clinical trial will be carried out using parallel groups and simple randomization. blinding will not be implemented in this research.
Settings and conduct
This study will be conducted in the university gym and participants will be invited to participate in the study through announcements on social media channels. After selection and obtaining consent, they will be randomly assigned to the intervention and control groups and will participate in aerobic and resistance training groups with a trainer on specific days for 8 weeks, 3 sessions of 90 minutes each week. Blinding will not be performed.
Participants/Inclusion and exclusion criteria
Inclusion criteria: not participating in regular physical activities for the past year, obesity (having a body mass index of 26-34) and no underlying disease. Exclusion criteria:Having cardiovascular disease, having musculoskeletal disorders
Intervention groups
Intervention group 1 consists of individuals engaged in aerobic exercises in the gym, including running with an intensity of 70-80% of the maximum heart rate, for 60 minutes and 30 minutes of warm-up and cool-down exercises. Intervention group 2, participants in resistance exercises in the gym with gym equipment, to develop muscle strength, will perform the exercises with an intensity of 70-80% of a maximum repetition, in 3 sets and 10-12 repetitions. The exercises of both groups are scheduled for 8 weeks and 3 sessions per week.
Main outcome variables
Cholesterol; Triglycerides; Low-density lipoprotein cholesterol; High-density lipoprotein cholesterol; MicroRNA-126; MicroRNA-221; Body fat percentage

Randomization description
After obtaining the participants' consent and providing complete information about the intervention implementation process, 30 samples will be selected from among the eligible people. There will be 30 volunteers in this study. In the second step, the numbers 1 to 30 are inserted on the paper and placed in the lottery container. The 15 people who chose even numbers from the lottery are in the resistance training group and the people who chose odd numbers are in the aerobic training group. Blinding is not performed in this study.

Intervention groups

1

Description
Intervention group 1: Participants in this group will engage in specific aerobic exercises at the gym for a duration of 8 weeks, attending 3 sessions each week. The exercises will be conducted at an intensity level of 70-80% of the maximum heart rate for a total of 90 minutes. The aerobic activities will consist of running in the gym for 60 minutes. During the initial four weeks, the exercises will be performed at an intensity of 60-70% of the maximum heart rate, structured into 4 sets of 10 minutes each, with 5 minutes allocated for active rest in between. From the fifth to the eighth week, the intensity will increase to 80-70% of the maximum heart rate, with 6 sets of 10 minutes each and 3 minutes of active rest. The exercises will be tailored according to the participants' age and gender. The intensity will be adjusted every 4 weeks based on the participants' progress. Each session will commence with a 15-minute warm-up and conclude with a 5-10 minute cool-down that includes stretching and flexibility exercises.

Description
Intervention Group 2: Participants in this group will engage in resistance training at an intensity of 70-80% of their one repetition maximum, performing 3 sets of 10-12 repetitions using exercise machines for 90 minutes, three times a week over a period of 8 weeks. During the initial sessions, their one repetition maximum will be assessed across various movements, and the first four weeks will commence with an intensity of 70-75% of the one repetition maximum. In the subsequent four weeks, following a new one repetition maximum test, the training will progress to 75-80% of the one repetition maximum based on individual progress. The resistance training regimen will encompass: leg curl and extension exercises, squats, chest presses, and overhead pull-down exercises using the machine. Each session will start with a 15-minute warm-up and conclude with a cool-down period of 5-10 minutes that includes stretching and flexibility exercises.
