“…Therefore, in Bruce's 2 Journal of Sensors treadmill test, the oxygen uptake level measured by the treadmill test is divided into three levels: (1) In the whole treadmill test process, based on the curves and graphs described by the theoretical interpretation and measured data, the mathematical method is expressed in the form of log curve to obtain the relationship between oxygen uptake and minute ventilation. (2) The point where the oxygen uptake of the body no longer increases with the increase of exercise intensity indicates that it can reach the maximum value of the aerobic ability level of the subjects in the plateau stage.…”

“…This study intends to use two methods, HIT (high-intensity interval training) and MICT (moderate-intensity continuous training), to explore the impact of these two training methods on the aerobic endurance of basketball players, and to provide reference for training. 37 male basketball players from two universities were selected as subjects, including 19 in the HIT group and 18 in the MICT group (see Table 1 for age, height, weight, and training years) [15]. The criteria for the subjects are as follows: maintain normal diet and living habits during training and have no history of major injury in the past 6 months.…”

“…Aerobic metabolism is the foundation. Good aerobic metabolism ability plays a protective role in accelerating the recovery rate after anaerobic metabolism, delaying the occurrence of sports fatigue, and making athletes bear high-intensity and heavy load [2]. Cardiopulmonary endurance plays a very important role in all ball games that require a long time (more than 30 minutes).…”

In order to explore the effects of HIT and MICT on aerobic endurance of college basketball players. By analyzing the difference between the cardiorespiratory endurance of basketball-specialized college students and the certain correlation between their athletic ability, it can better serve the practice of basketball training and provide certain theoretical guidance and theoretical guidance for the improvement of basketball-specialized college students’ athletic fitness, with a practical application value. 37 male college basketball players were randomly divided into the HIT group and MICT group. They were trained four times a week for 10 weeks. The special indexes of cardiopulmonary and basketball were measured during and before and after exercise. The experiment shows that the heart rate in HIT fast running stage is significantly higher than that in MICT, and the stimulation to cardiopulmonary function is stronger. HIT and MICT are difficult to improve athletes’ VO2max, but they can significantly improve the utilization rate of VO2max of VAT, and the effect of HIT is better than MICT. HIT and MICT have significant effects on improving the performance of 15 m × 17 × 4 run, and the former has obvious advantages. However, in terms of improving the performance of 3/4 sprint, HIT improved significantly.

Airline electromechanical actuators (EMAs), on the task of controlling flight surfaces, hold a great promise with the development of more- and all-electric aircraft. Notwithstanding, the deficiencies in both robustness and adaptability of control algorithms prevent EMAs from extensive use. However, the state-of-the-art control schemes fail to precisely compensate the system nonlinear uncertainties of servo control. In this paper, from the innovation point of view, we tend to put forward the foundation of devising an active disturbance rejection robust adaptive control (ADRRAC) strategy, whose main purpose is to deal with the position servo control of EMA. Specifically, an adaptive control law is designed and deployed for resolving not only the nonlinear disturbance, but also the parameter uncertainties. In addition, an extended disturbance estimator is employed to estimate the external disturbance and thus eliminate its impact. The proposed controlling algorithm is deemed best able to address the external disturbance based on the nonlinear uncertainty compensation. With the input parameters and control commands, the ADRRAC strategy maintains servo system stability while approaching the controlling target. Following the algorithm description, a proof of the controlling stability of ADRRAC strategy is presented in detail as well. Experiments on a variety of tracking tasks are conducted on a prototype of an EMA to investigate the working performance of the proposed control strategy. The experimental outcomes are reported, which verify the effectiveness of the ADRRAC strategy, compared to widely applied control strategies. According to the data analysis results, our controller is capable of obtaining an even faster system response, a higher tracking accuracy and a more stable system state.
