Contemporary cardiopulmonary rehabilitation programs often utilize cycling ergometer, involving one-on-one heart rate monitoring by physiotherapists to ensure that patients reach the target training intensity during training sessions. However, the process is frequently described as monotonous and boring, resulting in early fatigue of therapists and patients as well as poor compliance, leading to undertraining and suboptimal outcomes.
This study aims to test the feasibility of the "Intelligent Cardiopulmonary Training System (ICRS)" and a novel indicator of measuring the adherence to training intensity. The ICRS was developed with the idea to provide machine-based supervision on the user's heart rate during training. It provides moderate-intensity continuous training with a cycling ergometer. This system automatically adjusts the paddling resistance according to the user's real-time heart rate, and helps to improve the user's adherence to pre-determined training intensity without trainer's watch. The automation of intensity adjustment has its potential for conditions in which supervision is not feasible.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intelligent cardiopulmonary rehabilitation system (ICRS) | Experimental | The intelligent cardiopulmonary rehabilitation system is designed to improve the user's adherence to pre-determined training intensity. The training intensity is pre-determined using the 60%-80% heart rate reserve which is obtained from the cardiopulmonary exercise test at prestest. The system allows dynamically auto-adjust the paddling resistance in accordance to the patient's current hear rate and paddling rate, with the goal to maintain the patient's heart rate at the pre-determined heart rate zone through the training period. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Intelligent cardiopulmonary rehabilitation system (ICRS) | Device | Participants are required to wear a wristband heart rate monitor and exercise on a cycling ergometer-based ICRS for 30 minutes (5 minute of warm-up, 20 minutes of training followed by 5 minutes of cooldown). The target intensity for the 20-min training period is set at 60%~80% HRR determined in the pretest of cardiopulmonary exercise test. |

A small group of healthy subjects with sedentary lifestyle is recruited to validate the ICRS. They receive training with ICRS three sessions a week, for a total of 12 sessions. The outcome assessments are performed before and after the training.
