Home-based exercise interventions were the only alternatives to attenuate physical deconditioning and ameliorate traditional and emergent cardiovascular risk factors progression during the COVID-19 outbreak. Benefits in physical and psychological health have only been reported in adults without intellectual and developmental disability (IDD). The purpose of this study is to compare home vs gym-based delivery exercise modes of two 8-week supervised aerobic training regimes on cardiorespiratory fitness and arterial structure and stiffness in adults with IDD. It is hypothesized that home- and gym- based exercise delivery modes will be equally effective in improving cardiorespiratory fitness and overall arterial heath, although in an intensity dependent manner. A secondary analysis examining changes in blood pressure and body composition will be performed.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change in Cardiorespiratory Fitness | Each participant performed a ramp incremental cycle ergometer test to exhaustion on a calibrated electronically braked cycle ergometer (Monark 839 E, Ergomedic; Monark, Vansbro, Sweden) at a pedal cadence of 70-75 rev.min-1. The initial and incremental workloads were 10-20 watts. Inspired and expired gases were continuously analyzed, with mixing-chamber gas exchange measurements using a portable gas analyzer (K5, Cosmed, Rome, Italy). Before each test, the O2 and CO2 analyzers were calibrated using ambient air and standard calibration gases of known concentration (16.7% O2 and 5.7% CO2). Heart rate was continuously monitored (Garmin, US) and the participants did not carry the gas analyzer. Data were evaluated in 10 s averages, and peak VO2 (mL/kg/min) was defined as the highest 20-second value attained in the last minute. | Assessments were conducted on 4 occasions over a 20-week period: before (M1; 0 weeks) and after (M2; 8 weeks) the home-based intervention; and before (M3, 12 weeks) and after (M4; 20 weeks) the gym-based intervention. | |
Primary | Change in Arterial Stiffness | Arterial stiffness as measured by PWV (m/s) from piezoelectric pressure mechanotransducers placed on the carotid, femoral and distal posterior tibial arteries on the right side of the body. The operator positioned the carotid sensor with the help of its specific holder and manually held the femoral sensor on the femoral artery and the distal sensor on the distal posterior tibial artery. The right common carotid artery also was scanned with an Arietta V60 ultrasound machine (Hitachi Aloka Medical Ltd, Mitaka-shi, Japan) using a 7.5-MHz linear array probe incorporating a 5-MHz Doppler transducer. In longitudinal view, the intima of the artery was clearly imaged from both the anterior and posterior walls, and a single scan line was aligned perpendicularly to the vessel walls at a site 20 mm proximal to the carotid bulb. The corresponding displacement waveforms and diameter curve were thus calculated using high-resolution online wall tracking technology, with a sampling rate of 1 kHz. | Assessments were conducted on 4 occasions over a 20-week period: before (M1; 0 weeks) and after (M2; 8 weeks) the home-based intervention; and before (M3, 12 weeks) and after (M4; 20 weeks) the gym-based intervention. | |
Secondary | Change in Arterial Structure | cIMT (mm) measurements were recorded using high-resolution, non-invasive, semi-automated B-Mode ultrasound (Arietta V60; Aloka/Hitachi Medical Systems). The diameter was measured in M-Mode with a high-frequency linear array probe (7.5 MHz). cIMT was measured twice on the far wall of the common carotid artery, 1 cm proximal to the bulb at the end-diastolic moment (R-wave), when cIMT is thickest. The vascular diameter was measured at the same location as cIMT. The average minimum diameter value of the right common carotid artery, which corresponds to end-diastolic cIMT, was recorded from at least 5 heart cycles. Values obtained were compared to estimated age- and sex-specific percentiles of cIMT in populations with different cardiovascular risk profiles. | Assessments were conducted on 4 occasions over a 20-week period: before (M1; 0 weeks) and after (M2; 8 weeks) the home-based intervention; and before (M3, 12 weeks) and after (M4; 20 weeks) the gym-based intervention. | |
Secondary | Change in Body Mass Index | Height (cm) and body weight (kg) were measured to the nearest 0.1 cm and nearest 0.1 kg, respectively, on a scale with an attached stadiometer (model 770, Seca; Hamburg, Deutschland). Body Mass Index (BMI) was calculated as participant's weight in kilograms divided by the square of height (m). | Assessments were conducted on 4 occasions over a 20-week period: before (M1; 0 weeks) and after (M2; 8 weeks) the home-based intervention; and before (M3, 12 weeks) and after (M4; 20 weeks) the gym-based intervention. | |
Secondary | Change in Body Composition | Body composition (%fat; %muscle mass) was measured with a seca mBCA 515 using four pairs of electrodes (eight electrodes in total) positioned in each hand and foot. The 8-electrode technique enables segmental impedance measurement of the arms and legs. By this means, impedance was measured with a current of 100 µA at frequencies between 1 and 1 000 kHz. | Assessments were conducted on 4 occasions over a 20-week period: before (M1; 0 weeks) and after (M2; 8 weeks) the home-based intervention; and before (M3, 12 weeks) and after (M4; 20 weeks) the gym-based intervention. | |
Secondary | Change in Waist Circumference | Waist circumference was measured at the iliac crest (cm) to the nearest 0.1 cm. | Assessments were conducted on 4 occasions over a 20-week period: before (M1; 0 weeks) and after (M2; 8 weeks) the home-based intervention; and before (M3, 12 weeks) and after (M4; 20 weeks) the gym-based intervention. |
