Clinical Trial Summary

Objective: To show metabolic and hormonal responses and effects on abdominal obesity of aerobic exercise in different intensity and duration and detraining period in women with metabolic syndrome.

Description:

Objective: To show metabolic and hormonal responses and effects on abdominal obesity of aerobic exercise in different intensity and duration and detraining period in women with metabolic syndrome.

Methods: Fifty-one women with metabolic syndrome were divided into three groups: 12 weekly sessions of high intensity supervised treadmill group, respectively, at % 70 of maximum oxygen consumption (group I, n=17), low intensity supervised treadmill group, respectively at % 50 of maximum oxygen consumption (group II, n=17) and walking at low intensity, respectively at % 50 of maximum oxygen consumption with ECEPEDO pedometer (group III, n=17). Target heart rate (HR) corresponding to values of 50-70 % VO2max were determined by the submaximal treadmill test. Group 1 and 2 were instructed walking at their target HR on a treadmill. The number of steps taken in a minute corresponding to target HR was determined by a criterion pedometer and group 3 was instructed walking in this step range recorded to ECE PEDO giving audible feedback. Participants were evaluated by weight, BMI, waist circumference (WC), blood sugar, LDL, HDL and triglyceride; viseral fat, trunk fat and waist circumference by bioelectrical impedance device (VIScan); ergospirometric VO2max at baseline, 12-week and 4-week detraining period.

Intervention

Other:
• Supervised treadmill group (%70 VO2 max) (group 1)
An exercise prescription was developed for each woman on the basis of the data acquired from the baseline treadmill exercise test. Target heart rate (HR) corresponding to values of 70% VO2max were determined by the submaximal treadmill test. The participants were instructed walking at their target HR on a treadmill in Sports Rehabilitation Unit of Pamukkale University. HR was monitored by a Polar HR monitor (Polar Beat, Port, Washington, NY). During 12 weeks, 3 days in a week and 20 minutes per day walking program was applied.
• Supervised treadmill group (%50 VO2 max) (group 2)
An exercise prescription was developed for each woman on the basis of the data acquired from the baseline treadmill exercise test. Target heart rate (HR) corresponding to values of 50% VO2max were determined by the submaximal treadmill test. The participants were instructed walking at their target HR on a treadmill in Sports Rehabilitation Unit of Pamukkale University. HR was monitored by a Polar HR monitor (Polar Beat, Port, Washington, NY). During 12 weeks, 5 days in a week and 30 minutes per day walking program was applied.

Device:
• ECE PEDO pedometer group (%50 VO2 max) (group 3)
Target heart rate (HR) corresponding to values of 50 % VO2max were determined by the submaximal treadmill test. The number of steps taken in a minute corresponding to target HR was determined by a criterion pedometer and group 3 was instructed walking in this step range recorded to ECE PEDO giving audible feedback. During 12 weeks, 5 days in a week and 30 minutes per day walking program was applied.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	*Change from baseline in abdominal viseral fat and trunk fat and measured by VIScan at week 12 and 4-week detraining period.	BIA device ViScan, designed to estimate visceral adiposity and trunk fat percentage. A wireless 'electrode belt' is placed on the bare midriff of the subject in supine position. The belt then uses dual frequency bio impedance (6.25 and 50 kHz) to measure trunk and visceral fat resistance and transmit the readings via infrared to the base unit.	Week 12 and week 16
Primary	*Change from baseline in weight (kilograms) at week 12 and 4- week detraining period.	Weight was measured with weight scale.	Week 12 and week 16
Primary	*Change from baseline in Epinephrine/Adrenaline parameter at week 12 and 4- week detraining period.	Fasting blood samples were collected at morning hours before exercise testing. To perform adrenaline values, a sum of blood were stored at -80 C for later study.	Week 12 and week 16
Primary	*Change from baseline in noradrenaline parameter at week 12 and 4- week detraining period.	Fasting blood samples were collected at morning hours before exercise testing. To perform noradrenaline values, a sum of blood were stored at -80 C for later study.	Week 12 and week 16
Primary	*Change from baseline in free fatty acide parameter at week 12 and 4- week detraining period.	Fasting blood samples were collected at morning hours before exercise testing. To perform free fatty acide values, a sum of blood were stored at -80 C for later study.	Week 12 and week 16
Primary	*Change from baseline in oxyntomodulin parameter at week 12 and 4- week detraining period.	Fasting blood samples were collected at morning hours before exercise testing. To perform oxyntomodulin values, a sum of blood were stored at -80 C for later study.	Week 12 and week 16
Primary	*Change from baseline in glycerol parameter at week 12 and 4- week detraining period.	Fasting blood samples were collected at morning hours before exercise testing. To perform glycerol values, a sum of blood were stored at -80 C for later study.	Week 12 and week 16
