Protocol summary

Study aim
Comparison of the effect of aerobic and combined exercises on cardiovascular function and some cardiovascular risk factors in male lower limb amputation.
Design
The clinical trial has a control group, with two aerobic groups and a single-strain combination, randomized, on 45 lower limb amputation veterans. Randomization is done by block method and by an assistant outside the research.
Settings and conduct
The experimental groups receive the intervention related to them for 12 weeks at the Isar Hall in Shahrekord. The control group continues their usual activities during 12 weeks. The subjects are blinded to the grouping and the training sessions of the groups are done on different days.
Participants/Inclusion and exclusion criteria
Inclusion criteria included male gender, veterans 50-70%, age group 45-60 years, lower limb amputation, no history of metabolic disease and no smoking. Also, exclusion criteria include infectious diseases such as influenza and covid-19, non-participation in exercises,and use of anti-inflammatory drugs.
Intervention groups
The control group continues their usual activities during 12 weeks. Aerobic group exercises including 12 weeks of exercises will be done in 3 sessions per week. Exercises start in the first week with an intensity of 40% of the maximum heart rate and finally reach 70% of the maximum heart rate in the twelfth week. Combined group exercises include aerobic and resistance exercises for 12 weeks, 3 sessions per week. In the first week, resistance training starts as 2 sets with 8-12 repetitions and with 40% of 1 repetition maximum, and in the twelfth week it reaches 4 sets with 6-8 repetitions and with an intensity of 70% of 1 repetition maximum.
Main outcome variables
C-reactive protein; fasting blood sugar; cholesterol; triglyceride; IL-6; LDL; HDL; ESR V-CAM; LVEF; cardiac muscle hypertrophy; discharge deduction; blood pressure

Randomization description
After the announcement of the call and examination of the medical files, the candidates are enrolled in the study, and after the examination, based on the criteria of entry and exit from the study, 45 veterans of lower body amputations are selected as a sample. 45 samples are selected through available sampling and randomly divided into one of 3 groups: aerobic training (15 people), combined training (15 people) and control (15 people). Randomization is done by block method and by an assistant outside the research. In this way, the samples are randomized in the form of 3:3:3 blocks in each of the studied groups.

Intervention groups

1

Description
Intervention group: Aerobic exercise: Aerobic group exercises include 12 weeks of exercises, 3 sessions per week and each session is between 30 and 50 minutes and with increasing load. Each training session consists of three parts: warm-up, main training body and cool-down. Exercises start in the first week with an intensity of 40% of the maximum heart rate and finally reach 70% of the maximum heart rate in the twelfth week. Maximum heart rate measurement is evaluated using the formula (220-Sen). Also, the assessment of the heart rate of exercise using a polar hourly heart rate monitor.

Description
Intervention group: Combined exercise: Combined group exercises include aerobic and resistance exercises that are performed for 12 weeks, 3 sessions per week and each session between 30 and 60 minutes, with extra load. Each training session consists of three parts: warm-up, main training body and cool-down. The aerobic part of the exercises is performed in the same way as the aerobic exercise group, but with half the time of the aerobic exercise group. The resistance exercises section includes resistance exercises for the upper body with equipment and free weights for the main and large muscle groups of the upper body (head, forearm, chest, armpit, back of the arm, abdomen). Resistance exercises in the first week in 2 sets with 8-12 repetitions
