ADVERSE EVENTS
Before inclusion in the experimental study, the participants were informed of the purpose and content of the study, and each participant provided written informed consent by signing a consent form. All participants were informed of their right to withdraw from the experimental intervention at any time during the course of the experiment. Physiotherapists were instructed to stop the exercise intervention immediately if any participant experienced significant discomfort during the intervention.At baseline (PRE) and after 8 weeks of training (POST), we assessed scaled maximal isokinetic knee extension strength at 60°/s and 180°/s, the sum of the thickness of the affected the rectus femoris and vastus intermedius, Y-balance test performance, and International Knee Documentation Committee questionnaire responses. Self-reported adverse events were recorded throughout the protocol.One-to-one intervention training was provided by four physiotherapists with over three years of experience. The physiotherapist underwent two consecutive two-hour training sessions as part of the study protocol. The first session took place one week before the start of the intervention, while the second session was held four weeks after the intervention had commenced. The training consisted of detailed explanations and demonstrations of the intervention program, including instructions on the proper use of the AirBands which was sourced from the VALD Performance company in Australia.Pressurization method: We utilized AirBands as our compression equipment. After the participant has rested on the treatment bed for five minutes, the physical therapist operates a mobile phone app connected via Bluetooth to a compression device to automatically measure the participant’s maximum arterial occlusion pressure. The degree of compression for the exercise was measured and adjusted based on the measured arterial occlusion pressure of the participant. During the training process, after completing each exercise, the participant rested for 30 s, and the mobile phone software operated the equipment for deflation and pausing. After this 30-second rest, the pressurized belt was automatically inflated to the last set pressure value. This process was repeated until the training was complete.Exercise protocols: During the eight-week intervention, all participants were required to complete a total of 16 training sessions, consisting of two sessions per week, with each session lasting approximately 60 min. Each training session included a 10-minute walking warm-up, followed by two quadriceps training exercises. Participants also completed stretching exercises for relaxation after each training session. During each training exercise, participants were instructed to complete four sets of 30 repetitions for the first set, and 15 repetitions for the remaining sets, with a 30-second rest between each set. The intensity of the exercises was adjusted based on individual participant needs and progression throughout the intervention. Male participants utilized green Thera-Band USA elastic bands, while female participants utilized red ones. The weight of the barbell bar employed for weight training was 20 kg. For males, the barbell bar was loaded with 10 kg on each end, whereas for females, the bar was utilized without additional weights. The load could be adjusted according to the participant’s requirements and the principle of adjustment was that 5 kg barbell weights could be added to each end of the bar. Table
