Brief Summary

The study consisted of a non-randomized controlled clinical trial with measurements at baseline and at the end of a 16 week intervention. Participants will be assigned to the intervention or control group according to their own choice and convenience. A 4 arm split was performed where the Veg-Int group was composed of people on a vegan diet who participated in the intervention, the Veg-Con group was composed of people on a vegan diet who were part of the control group, the Omn-Int group was composed of people on an omnivorous diet who participated in the intervention, and the Omn-Con group was composed of people on an omnivorous diet who were part of the control group. The Veg-Int and Omn-Int intervention groups, participated in a physical exercise program in remote modality through a digital mHealth platform. During the 16 weeks of intervention, a total of 50 training sessions were carried out, distributed in three sessions per week, with a duration per session ranging from 40 to 50 minutes. The exercise program was designed and supervised by a physical education teacher and focused on strength training using body weight exercises targeting the major muscle groups, including upper body, lower body and abdominals. The platform recorded participants attendance and the time they spent on each exercise session. At the end of the sessions, participants had the option to evaluate and share their perception of effort during the workout through a Modified Borg scale (0-10). In addition, they were given the opportunity to communicate with the teacher via phone call, text message or e-mail, to receive feedback or raise doubts.

Study Arms (4)

Vegan Intervention

EXPERIMENTAL

The intervention group is composed of people who follow a vegan diet and who will be part of an intervention program for 16 weeks, consisting of a physical exercise program of strength resistance with 3 sessions per week. Each session will be guided by a physical activity professional and will last from 45 to 50 minutes.

Other: Strength training program

omnivorous intervention

EXPERIMENTAL

The intervention group is composed of people who follow a omnivorous diet and who will be part of an intervention program for 16 weeks, consisting of a physical exercise program of strength resistance with 3 sessions per week. Each session will be guided by a physical activity professional and will last from 45 to 50 minutes.

Other: Strength training program

vegan control

NO INTERVENTION

People who follow an vegan diet who were part of the control group. They were evaluated before and after the intervention.

omnivorous control

NO INTERVENTION

People who follow an omnivorous diet who were part of the control group. They were evaluated before and after the intervention.

Interventions

Strength training program OTHER

Strength training program to be developed during 16 weeks. There will be 3 exercise sessions per week and those participants who perform at least 2 sessions during the program will be considered for the statistical analysis.
