This study is designed to evaluate the safety, feasibility, and effectiveness of a 12-week eccentric exercise program for older adults with sarcopenia (muscle loss) or sarcopenic obesity and chronic heart failure (HF). The program aims to improve physical performance, muscle strength, and overall health without causing excessive strain on participants. Eccentric exercise has shown potential benefits for improving muscle function, and this study will help determine if it is a safe and effective option for individuals with heart failure and muscle loss.
Study Goals: The primary aim of this study is to test the feasibility and effectiveness of an eccentric exercise program for older adults with sarcopenia and CHF. The study will monitor physical performance, adherence to the program, and participants' ability to tolerate the exercise, as well as any impact on heart and muscle health.
Study Population: A screening visit will be scheduled to determine if individuals meet the criteria to participate in the study. During this visit, a detailed assessment will be made, and if eligible, participants will sign an informed consent form.
This study will assess whether a 12-week eccentric exercise program can help improve muscle strength, cardiovascular health, and overall physical performance in individuals with HF and sarcopenia. The program will involve exercising on an eccentric bike, which is designed to reduce strain on the heart while providing effective muscle strengthening benefits.
The study will use several physical performance tests to assess the impact of the exercise program, including:
Primary Outcomes
Feasibility Measures:
To be considered feasible, the study must meet these criteria: Recruitment >50%, Follow-up loss <20%, Median attendance at training sessions >80%, Median adherence to prescribed volume >75%, Tolerance to RPE >70%.
Secondary Outcomes
Effectiveness Measures:
In addition to the physical performance tests mentioned, the study will assess muscle mass and fat distribution using DXA scans and BIA, providing a comprehensive view of body composition. Finally, the feasibility of remotely monitoring patients' physical activity to determine the impact of the intervention on their daily lives, specifically in terms of mobility and autonomy is assessed. To this end, patients will be asked to wear a set of five sensors (two on the ankles, two on the wrists, and one on the waist) for at least four days. The Axivity AX6 sensors, chosen for their light weight and long battery life, will collect data used to monitor time spent moving, sitting, and lying down, as well as to assess the quality of the recorded movements.
Training protocol overview Familiarization Phase Before starting the actual training program, patients will undergo a familiarization phase to allow them to adjust to the eccentric cycling equipment and understand the intensity of the exercises. This phase is critical for ensuring safety and optimizing adherence to the program.
Duration of Familiarization:
The familiarization phase will last for two weeks. The first week (sessions 4 and 5, conducted within the same week after medical screening and body composition testing) will focus on achieving an intensity that is perceived as "very light" (RPE 8-9) and maintaining it for 5-10 minutes.
The second week will aim for a light (RPE 10-11) to slightly heavy (RPE 10-13) intensity.
Muscle Pain Monitoring:
At the beginning and end of each familiarization session, patients will be asked to rate their muscle pain using the Visual Analog Scale (VAS) (0-10), where 0 represents no pain and 10 indicates unbearable pain. This ensures that any discomfort is monitored and managed appropriately, reducing the risk of muscle injury and enhancing adherence to the program.
Purpose of Familiarization:
This phase helps patients adapt to eccentric training, preventing unnecessary muscle damage and ensuring they are comfortable with the equipment and the level of exertion. It also serves to acclimatize the patients to the specific eccentric muscle contractions involved in the cycling exercise.
Exercise Prescription Trained kinesiologists will supervise the eccentric cycling sessions. Monitoring and adjusting exercise intensity based on heart rate (HR) and Rate of Perceived Exertion (RPE) will be central to ensuring safety and effectiveness throughout the intervention.
Intensity Monitoring: For participants on beta-blockers, maximum heart rate (HRmax) will be estimated using the formula: HRmax = 164 - (0.7 × age). For participants not on beta-blockers, HRmax will be calculated using: HRmax = 211 - (0.64 × age).
The HR and RPE will be continuously monitored to ensure participants are training within the prescribed intensity zones.
Target Intensity: The training intensity will be kept between light (57-64% of HRmax) and moderate/slightly heavy (64-76% of HRmax) levels. These ranges correspond to RPE values of approximately 10-14.
The intensity will vary within the session, with three different workloads: Light: RPE ~10, Moderate: RPE ~12, Slightly Heavy: RPE ~14
Session Structure: Each training session will be divided into three parts:
The duration of the central training phase will start at 20 minutes. Week 5-8 (Strengthening Phase): Training frequency will increase to three times per week. The duration of the central phase will increase progressively to 30 minutes. The intensity will gradually rise within the prescribed target range, increasing as the patients adapt.
Week 9-12 (Maximal Tolerable Load Phase): The frequency remains three times a week. The intensity will reach the higher end of the prescribed range, with patients performing the eccentric cycling at near-maximal intensities (RPE 14-15). Adjustments Every Two Weeks: Every two weeks, the workload will be reassessed and adjusted to ensure the target RPE is achieved and maintained. This will ensure continued progression and avoid plateauing.
Pedaling Frequency: Participants will be instructed to maintain a pedal cadence of 60 RPM (revolutions per minute) for each session. This will be a consistent cadence for the entire training phase.

| Physical Activity Level (IPAQ) | The International Physical Activity Questionnaire (IPAQ) is a widely used self-reported tool designed to assess physical activity levels in adults. It was developed by the World Health Organization (WHO) to provide a standardized method for evaluating physical activity across different countries and cultures. The IPAQ is commonly used in both research and public health settings to assess activity levels and promote physical activity. Total Physical Activity Score = Sum of the activity frequency (days per week) multiplied by the duration (minutes per day) for each activity intensity (vigorous, moderate, walking). The score is then categorized based on the thresholds above to identify low, moderate, or high activity levels. | Only at PRE. |
| Weight | Measured by a scale. Values collected in kg. | Pre and after 12 weeks |
| Height | Height measured by stadiometer. Values collected in meters (m). | Only at PRE. |
| Body Mass Index | Body Mass Index (BMI) is a simple and widely used tool to assess body weight relative to height and categorize individuals into various weight status groups. While it does not directly measure body fat percentage, BMI is used as a general indicator of whether a person has a healthy weight for a given height. It is particularly useful for population-level assessments and as a quick screening tool in clinical settings. Calculated as weight (kg)/height² (m²), kg/m². | Pre and after 12 weeks |
| Waist circumference | Waist circumference is a simple and widely used measure of abdominal fat. It is particularly important in assessing the risk of metabolic and cardiovascular diseases, as abdominal fat (specifically visceral fat) is associated with higher risks of conditions such as type 2 diabetes, hypertension, and heart disease. Measure in centimeters (cm). | Pre and after 12 weeks |
| Hip circumference | Hip circumference is the measurement of the circumference around the widest part of the hips and buttocks, typically measured at the level of the greater trochanters (the bony prominence on the outer side of the hip). Measure in centimeters (cm). | Pre and after 12 weeks |
| Calf circumference | Calf circumference is a simple measurement of the circumference around the widest part of the lower leg, specifically the gastrocnemius muscle area. It is often used in clinical and research settings to assess nutritional status, muscle mass, and vascular health, especially in individuals who may have muscle wasting or vascular conditions. Smaller calf circumference is often a marker of frailty and sarcopenia in older adults, which is linked to reduced physical function, increased risk of falls, and reduced mobility. Record the measurement: Measure in centimeters (cm). | Pre and after 12 weeks |
| Muscle mass | Muscle Mass will be measured through a Dual-Energy X-ray Absorptiometry (DEXA). A DEXA scan is a highly accurate and widely used imaging technique primarily used to measure bone mineral density (BMD), but it can also provide detailed information about body composition, including muscle mass, fat mass, and bone mass. DEXA scans are commonly used in both clinical and research settings to assess muscle mass, fat distribution, and bone health. Values in kg. | Pre and after 12 weeks |
| Fat Mass | Fat Mass will be measured through a Dual-Energy X-ray Absorptiometry (DEXA). A DEXA scan is a highly accurate and widely used imaging technique primarily used to measure bone mineral density (BMD), but it can also provide detailed information about body composition, including muscle mass, fat mass, and bone mass. DEXA scans are commonly used in both clinical and research settings to assess muscle mass, fat distribution, and bone health. Values in kg/%. | Pre and after 12 weeks |
| Bone Density | Bone Density will be measured through a Dual-Energy X-ray Absorptiometry (DEXA). A DEXA scan is a highly accurate and widely used imaging technique primarily used to measure bone mineral density (BMD), but it can also provide detailed information about body composition, including muscle mass, fat mass, and bone mass. DEXA scans are commonly used in both clinical and research settings to assess muscle mass, fat distribution, and bone health. Values in g/cm². | Pre and after 12 weeks |
| Short Physical Performance Battery | The Short Physical Performance Battery (SPPB) is a widely used clinical assessment tool designed to measure lower extremity function and physical performance in older adults. It is particularly useful for identifying early signs of frailty, functional decline, and mobility issues. The SPPB is a brief and reliable tool that evaluates multiple aspects of physical function through a series of simple tasks. The SPPB consists of three main tests: Gait Speed Test, Balance Test and Chair Stand Test. The SPPB provides a total score based on the performance of each test. The total score ranges from 0 to 12 points, with higher scores indicating better overall physical performance. | Pre and after 12 weeks |
| Six Minute Walking Test | The 6-Minute Walk Test (6MWT) is a simple, widely used functional exercise test that measures an individual's endurance, aerobic capacity, and physical fitness. It is commonly used in clinical and research settings to assess the functional status and exercise tolerance of individuals. The person is instructed to walk continuously without running or stopping (unless necessary), and to pace themselves at a speed they feel comfortable with. The total distance walked in meters (m) is recorded at the end of the 6 minutes. | Pre and after 12 weeks |
| Ten Meter Walking Speed | The Ten-Meter Walking Speed Test (10mWT) is a commonly used simple and reliable test to assess gait speed and walking ability in individuals, particularly older adults and those with health conditions affecting mobility. It provides valuable information about an individual's functional mobility and is often used in clinical and research settings to assess frailty, cognitive function, and the risk of falls. The subject is instructed to walk at their normal, comfortable pace over the 10-meter course. This test is performed without running and with the individual walking continuously from one end to the other. The time taken to cover the 10 meters is recorded, and the result is expressed in seconds (s) which can be used to assess walking speed in m/s. | Pre and after 12 weeks |
| HandGrip | The Handgrip Strength Test is a simple and widely used measure of muscle strength, specifically the strength of the hand and forearm muscles. It is commonly used in clinical and research settings to assess overall muscle function, health, and frailty, particularly in older adults or individuals with conditions that may affect muscle strength and physical performance. The subject is asked to squeeze a handgrip dynamometer (a device designed to measure grip strength) as hard as possible for a few seconds for three attempts. The maximum force applied during the squeeze is recorded in kilograms (kg). | Pre and after 12 weeks |
| Isometric Force | Isometric force testing with a Cybex dynamometer provides precise measurements of muscle strength, which are important for assessing an individual's functional ability, recovery, and rehabilitation progress. In this study, the subjects will perform maximal isometric contractions with the knee angle at 90 degrees. Two tests will be performed, separated by 2 minutes of recovery. The value will be expressed in Newton x Metre (Nm). | Pre and after 12 weeks |
| Isokinetic Force | Isokinetic Force refers to the force exerted by a muscle during an isokinetic movement, where the velocity of the joint motion is kept constant throughout the range of motion. Isokinetic testing is often used to assess muscle strength, endurance, and power under controlled conditions. Isokinetic refers to a type of muscle contraction where the velocity of movement (the speed at which the limb moves) is kept constant by the testing equipment, regardless of the force the muscle is generating. This is achieved using isokinetic dynamometers, which can measure and control the speed of joint movement during the test (e.g., Cybex). These devices adjust resistance based on the muscle's output, ensuring that the joint velocity remains the same. In this study, the participants will perform two familiarization contractions and three evaluation contractions, both in extension and flexion, at the following speeds: 60, 90, 150, 180, and 210 °/s. The values will be recorded in Newton x Metre (Nm) | Pre and after 12 weeks |
