The effect of two methods of aerobic and resistance training on arterial stiffness and inflammatory biomarkers was compared .
Design
Two groups of aerobic and resistance training without a control group ,Randomized
Settings and conduct
In this study, both groups completed exercises under the supervision of a coach and the researcher at 22 Bahman Sports hall of Ferdowsi University of Mashhad.The aerobic exercise included riding a spin bike for 35 to 50 minute per session. Resistance training encompassed progressive upper and lower body workouts using six sports devices.
Participants/Inclusion and exclusion criteria
27 to 42 years old, Women, Obese, Healthy
Intervention groups
This research was performed on 27 sedentary obese females.The subjects were randomly assigned into two groups of aerobic (n=14) and resistance training (n=13). The first group was subjected to 8 weeks of aerobic exercise in form of riding a stationary bike at an intensity of 50-70% of the maximum heart-rate reserve. In the second group, the participants performed resistance training for 8 weeks with 60-85% intensity of one repetition maximum (three sessions a week).

Randomization description
Based on the number of samples, some cards were prepared and half of them were labeled as aerobic and the other half as resistance training and all the cards were placed in a container. Then, each participant was asked to pull out a card and based on he label, participant was placed one of the groups.

Description
Intervention group: The aerobic exercise included riding a spin bike for 35-50 min per session at an intensity of 50-70% of the maximum heart rate. The workout consisted of three sections: warm-up including static and dynamic stretching (5 min), riding the spin bike (25-40 min), and cool-down (5 min) as stretching moves. The exercise program was performed for 35 min with at an intensity of 50-60% of the maximum heart rate reserve throughout the first and second weeks, followed by 40 min with the intensity of 50-60% during the third and fourth weeks. On the fifth and sixth weeks, the individuals performed the exercise for 45 min at an intensity of 60-70% of the maximum heart rate reserve. Afterward, they completed 50 min of exercise at an intensity of 60-70% during the seventh and eighth weeks. The exercise intensity was controlled by the Polar wrist heart rate monitor throughout the exercise.

Description
Intervention group: The plan for resistance training was designed similar to that of DeVallance et al. (2016). Resistance training encompassed progressive upper and lower body workouts using six sports devices. Warm-up and cool-down were performed in the beginning and at the end of the exercise for 5 min by stretching. In the first session, the subjects were familiarized with the devices and the one repetition maximum (1RM) was measured for the exercises related to the upper and lower extremities. In each session, the upper-body exercises required the use of special devices, including vertical chest press, triceps extension, and biceps curl. In addition, leg curl, leg extension, as well as multi hip exercise were applied for lower-body workouts. The intensity of resistance training increased progressively every 2 weeks as follows: the first and second weeks with 60% of 1RM, the third and fourth weeks with 70% of 1RM, the fifth and sixth weeks with 80% of 1RM, followed by the seventh and eighth weeks with 85% 1RM. The participants were encouraged to complete 8-12 repetitions until they were able to perform the exercises properly on their own. In addition, 30-second and 1-min rests were considered between the sets and devices, respectively. .
