ABSTRACT
Objective To observe the effects of short-term blood flow restriction (BFR) based on limb linkage training on cardiopulmonary endurance, lower limb muscle endurance and balance function of healthy people. Methods From December, 2019 to March, 2020, 20 healthy young people were randomly divided into control group (n = 10) and experimental group (n = 10). They accepted limb linkage training with the loading of anaerobic threshold (AT) according to the results of cardiopulmonary exercise test (CPET), 20 minutes a time, three times a week, for two weeks; while the experimental group wore 250 mmHg blood pressure training belt at the root of both thighs; the control group wore blood pressure training belt with no pressure. They were assessed with CPET, 6-minute walking test, wall squatting, seat test and functional reach test before and after training. Results After training, all the indexes improved in both groups (|t| > 2.321, P < 0.05), except functional reach test, the results of wall squatting and seat test were better in the experimental group than in the control group (t > 2.660, P < 0.05). Conclusion Limb linkage training combined with lower extremity BFR could further improve lower limb muscle endurance.
