Details and patient eligibility

About

Study design The study was designed as a prospective controlled randomized trial. Participants were randomly assigned to one of two groups. In the experimental group, participants (n = 17) received 8-week aerobic exercise intervention without nutrition modifications. In the control group, participants (n = 16) did not undergo any intervention and were instructed to maintain their regular physical activity and diet regime for 8 weeks.

Experimental measurements: Anthropometric measurements, Measurement of BDNF, Cardiac autonomic responses, Measurement of aerobic fitness, Measurement of cognitive functions.

Enrollment: 33 patients

Sex: Female

Ages: 38 to 56 years old

Volunteers: Accepts Healthy Volunteers

Aerobic exercise

Experimental group

Description:

Exercise intervention. The experimental group increased their energy expenditure according to American College of Sports Medicine and WHO-based physical activity recommendations for all adults to promote clinically significant weight loss and for additional health benefits: 300 min of moderate-intensity aerobic training throughout the week (WHO, 2010; Swift et al. 2014). Participants underwent five 60 min moderate-intensity cycling sessions per week for a period of 8 weeks, 40 sessions in total. Each session involved 5 min of warm up at 40 Watts, cycling for 50 min at a speed that increased their HR to a target HR obtained at 50-60% of peak VO2, and a 5 min of cool down at 40 Watts.

Treatment:

Other: Aerobic exercise

Control

No Intervention group

Description:

. In the control group, participants did not undergo any intervention and were instructed to maintain their regular physical activity and diet regime for 8 weeks.
