About this study
Official title: The Effect of Mixed Aerobic and Strength Training Program on Physical Fitness and Cerebrovascular Function in Older Women With Metabolic Syndrome: A Pilot Study With Randomized Control Trial (RCT) Design
The purpose of this study is to test whether a supervised mixed aerobic and strength training (MAST) program is effective in improving overall physical fitness and blood flow in the brain and lowering risk factors of coronary artery disease (CAD) in women with metabolic syndrome.
Read the detailed description
Metabolic syndrome is a cluster of conditions and disorders that increase the risk for coronary artery disease (CAD) and strokes. Sedentary lifestyle is one of the risk factors, which decrease overall physical fitness and together with aging may lead to decrease in physical functioning in everyday life as well as changes in blood flow in the brain and cognitive functions. Regular physical activity is associated with a reduced risk of cardiovascular disease. It may also improve blood flow velocity and cognitive functions. Physical activity should be as effective as possible, but also as safe as possible. Supervised mixed aerobic and strength training (MAST) program for 4 months enables to individualize the intensity of aerobic exercise based on measured maximal exercise capacity. Throughout each training session heart rate will be monitored with a new real time wireless ECG system.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
MAST programBehavioural
MAST program: twice a week for 4 months
| Study group | Role | What they receive |
|---|---|---|
| MAST program | Experimental | Mixed Aerobic and Strength Training program (MAST): Each exercise session consisted of 10 minutes of warm-up, 15-30 minutes of interval aerobic training by cycle ergometer according to the program, 20 minutes of strength training exercises, and 10 minutes of cool-down by stretching. Receives: Behavioral: MAST program |
| UC | No intervention | Usual Care (UC) with Educational Lectures: No exercise sessions. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Maximal Oxygen Uptake
To obtain peak oxygen uptake (VO2max; ml-1/min-1/kg), a symptom-limited exercise stress test was performed on a cycle ergometer. The test was preceded by a 2-minute warm-up at the intensity of 20 W. The first test load was 20 W, and was increased by 20 W at each 2-minute stage until the participants could no longer continue, i.e., they were unable to maintain pedaling frequency > 40 rpm, they achieved a respiratory exchange ratio of more than 1.0, or clinical criteria for test termination was observed. VO2max was measured and monitored with a breath-by-breath gas exchange system.
Measured: At baseline and after 4 months of intervention
Secondary outcomes (3)
Cerebral Blood Flow Velocity (BFV)
Cerebral BFV was monitored using Transcranial Doppler Ultrasound.11 The middle cerebral artery was insonated from the temporal window by placing the 2-MegaHertZ (MHz) probe against the skin of the temporal region above the zygomatic arch. The probe was positioned to obtain maximal BFV and was fixed at the desired angle using a 3-dimensional positioning system. Once instrumented, BFV was continuously recorded throughout ten minutes of supine rest and 10-minutes on a table tilted to 80° from the horizontal position (head-up with foot plate support).
Measured: At baseline and after 4 months of intervention
Trail Making Test
The Trail Making (TM) test is a measure of shifting attention. Participants are required to sequentially connect a series of numbered circles (Part A), and then to alternate between numbers and letters sequentially (Part B) (e.g., A-1-B-2-C-3..). Any participant who has not completed Part B within the standard 5 minutes (300 seconds) allotted for the task will be considered unable to complete the task. The scores in Part A (TM-A), Part B (TM-B) T scores ( age, education adjusted), and their difference (TM-B -TM-A) were calculated and used to measure executive function, i.e., lower scores indicates better performance.
Measured: At baseline and after 4 months of intervention
Muscle Strength
MAST sessions were held twice a week for 16 weeks. Each exercise session consisted of 10 min of warm-up, 15-30 min of interval aerobic training by cycle ergometer according to the program, 20 min of strength training exercises, and 10 min of cool-down by stretching. The target heart rate (HR) increased progressively from 50% up to 80% of HR reserve by the end of the intervention period.The Karvonen formula ([(HRmax - HRrest)×(0.50 to 0.80)] + HRrest) was used to calculate the target HR. During every training session a new wireless computerized ECG monitoring system was used. After aerobic training, the strength training program was performed. Exercises used body mass as resistance and included squat, step-up-squat, step-up, heel rise, and sit-ups. Dumbbells were used as extra weight (5 or 10% of body weight) during other exercises except for sit-ups. The control group participated in an educational session once a month and kept physical activity diaries during the intervention period.
Measured: At baseline and after 4 months of intervention
