• Recruitment Status: COMPLETED
• Total Enrollment: 8 participants

Brief Summary

The Intelligent Cardiopulmonary Rehabilitation System (ICRS) was developed to automatically control the resistance of pedaling in combination with the conventional stationary bike by monitoring the user's heart rate for clinical use. To test its feasibility, 8 healthy participants were recruited to complete 12 sessions (3 times per week for 4 weeks) of indoor cycling on the stationary bicycle with ICRS. Subjects were received cardiopulmonary exercise testing (CPET) before and after the biking sessions.The 60-80% of heart rate reserve (HRR) of each participant was determined according to their first CPET results. The algorithm of ICRS was designed to enable the bicycle to adjust its training intensity in accordance with the subject's 60-80% HRR which was detected by wearing a wristband heart rate monitor during cycling. With ICRS, the participants' heart rates during training were expected to fall in the 60-80% HRR, increasing their cardiopulmonary fitness after 12 sessions of indoor cycling.

Conditions

Cardiac Rehabilitation

Study Design

• Observational Model Type: CASE_ONLY
• Study Time Perspective: RETROSPECTIVE

Study Groups

Indoor cycling training

8 subjects were asked to complete indoor cycling training, 3 times a week for 4 weeks. Each session of training consisted of 30-minute stationary biking (5 minutes of warm-up, 20 minutes of training and 5 minutes of cooldown).

ICRS

Intervention Type: DEVICE

The ICRS enables a stationary bike to automatically adjust the pedaling resistance (i.e. training intensity) according to the subject's heart rate. The training intensity is determined by monitoring whether the subject is able to maintain a 50-70 cycles/min cadence with 60-80% HRR. Subjects heart rate was detected by a wearable device for heart rate, synching with the stationary bike.
