“…Related scholars configure the impedance control parameters of the controller through a set of heuristic control parameters and a set of motion state values for normal motion, and the effect is significantly shortened ( Park et al, 2020 ). In addition, with the development of related disciplines such as pattern recognition, there are more and more studies on the control of dynamic bionic legs by using human EMG signals as control signals ( Gogoi et al, 2021 ). The combination of the signal and the neuromuscular reflex model framework can be directly used for the control of the dynamic prosthesis to realize the stable switching of the prosthesis on the level ground and between up and down stairs.…”

Based on the spectral representation method of random function and combined with memoryless nonlinear translation theory, this paper analyzes the transformation relationship between potential Gaussian random process and non-Gaussian random process, and successfully generates a stationary non-Gaussian random process that conforms to the target non-Gaussian random process. For the non-stationary non-Gaussian random process simulation, on the basis of the stationary Gaussian random process, the intensity non-stationary uniform modulation model is used to modulate it, and combined with the nonlinear translation theory, the non-stationary non-Gaussian random process conforming to the target non-Gaussian random process is obtained. Aiming at the single-leg bouncing model based on the flexible rotary hip joint, the stability of its bouncing motion under passive motion is studied, and the influence of the flexible hip rotary joint on the motion stability is analyzed by comparing the single-leg bouncing motion characteristics of the free rotary hip joint. Based on the inverse dynamic control of the air phase, the fixed point distribution of the single-leg bounce of the flexible rotary hip joint was improved, and the function of the flexible rotary hip joint in the energy conversion of the bouncing motion was studied by establishing the energy consumption evaluation function. The kinematic performance verification, dynamic performance verification, dynamic parameter identification verification, and modal experiment simulation analysis were carried out for the built experimental platform, and the comparison and analysis with its theoretical model were carried out. The results show that the theoretical motion trajectory of the test mobile platform is basically consistent with the actual motion trajectory in the X and Y directions, and there is a small error in the Z-axis direction, and the error is within an acceptable range, indicating that the experimental platform system can be used to simulate the human hip joint. There is a large error between the theoretical value of the driving torque calculated by the theoretical value of the dynamic parameters and the measured value, and the dynamic theoretical model cannot accurately predict the driving torque. The predicted value of the driving torque calculated by using the identification value of the dynamic parameters is in good agreement with the measured torque, and its confidence is increased by 10–16%, indicating that the dynamic parameter identification method in this paper has a high degree of confidence.

“…In previous studies of plyometric training, results supported the improvements in specific physical abilities in as little as eight weeks of plyometric training, which can be useful during the last preparatory phase before in-season competition for athletes [21,22,23] . Another researcher has reported that eight weeks of plyometric exercises can develop horizontal jump performance [24,25] . Eight weeks of plyometric training added to the standard training program of athletes was highly likely to improve young athletes' lower limb speed and explosive strength.…”

The goal of the present study was to find out the effect of plyometric training on repeated countermovement jump performance of collegiate athletes. A total of six variables of repeated countermovement jump, i.e., height (HT), take-off force (TOF), impact force (IF), maximum concentric power (MCP), peak speed (PS), and take-off speed (TOS), were selected to fulfil the objective of the study. A total of twenty (N=20) participants were randomly selected from a physical training centre of the Gwalior area of India as the subjects for the study. The average age of the participants was 18.40±1.19 years. The subjects were randomly divided into two groups. Each group consists of ten participants. One group was treated as the experimental group, and another was treated as the control group. To find out the effect of plyometric training a randomized control group pre-test post-test design was adopted in which the experimental group received eight weeks of plyometric training whereas the control group received dummy training. The training was given twice a week to both groups. Pre and post-data were collected before and after the eight weeks of plyometric training. The statistical technique independent t-test was used to compare the performance of the experimental and control groups, whereas paired t-tests were used to compare pre-and post-test data at 0.05 level of significance. The findings showed that eight weeks of plyometric training significantly improved the variable height, take-off force and maximum concentric power.

“…There are numerous methods and techniques available in modern times to assess the career as well as injury graph of the athletes (Gogoi et al, 2020, 2021) [9,8] . Those methods may be applied in assessing the injury patterns of the fast bowlers as well.…”

Keeping in mind the research question "does bowling fast really accomplish the very purpose of bowling i.e., getting wickets?", a study was conducted to reach to a conclusion and factors associated with fast bowling. With the help of online data available on reliable platforms such as cricbuzz.com and ESPN CricInfo, bowlers who have bowled the fastest deliveries were selected. Some delimitations were applied to refine the data. Bowlers' records including overall wickets taken, matches played, and bowling strike rate were considered for the study. These records were compared against the records of the most successful bowlers in international cricket. Further, a few recommendations for future studies were outlined.
