This study investigated the postactivation performance enhancement (PAPE) effects of medicine ball throwing (MBT) and bench pressing (BP) on punching impact at different recovery times.įourteen amateur boxers performed three lead-hand (lead-hand) and rear-hand straight punches (rear-hand) at 3, 6, 9, 12, and 15 min after MBT or BP exercise. Therefore, it is believed that this new teaching method based on DL plays a significant role in improving students’ physical quality. Their time on a 1000-meter long run is shortened, and their body flexibility is improved. The questionnaire survey shows that the students’ academic performance in solid ball throwing is improved, and their problem-solving ability, group cooperation ability, and theory learning ability are improved. The students’ interest, learning ability, and physical quality in the solid ball are investigated by a questionnaire survey. This method is employed to teach the experimental subjects in solid ball throwing. Problem-based learning (PBL) is introduced, and a new teaching method of PE is proposed based on the convolutional neural network (CNN) in deep learning (DL). This study aims to arouse students’ interest in physical education (PE) in response to President Xi Jinping’s call to strengthen students’ physical quality because cultural courses occupy PE classes. Additionally, it shows how trained athletes can achieve similar outcomes during ballistic movements using a variety of movement strategies. This project highlights the complexity of the relationships between power production and upper body kinematics during light load ballistic MBP-P throwing. Analysis of inter-trial variability showed that the gross measures of performance and power were relatively stable (Coefficient of Variation <13%), while most upper limb segmental kinematics varied considerably between trials (CV% up to 70%). Comparative analyses indicated that despite significant reductions in Velpeak from the 5% to 10% loads (P < 0.001), Fpeak remained largely unchanged (P = 0.167). Gross measures of performance and power production such as peak vertical ball velocity (Velpeak), peak force (Fpeak) and power (Ppeak) were recorded during the propulsive phase of the movement. Throws were performed lying supine on a force platform (1 kHz) with upper body kinematics assessed using standard infra-red motion capture techniques (0.5 kHz).
#Per4m upper body power booster series
Twenty-five regular weight trainers (body mass = 86 ± 10 kg) performed a series of ballistic vertical MBP-P throws at loads representing 5% and 10% of their assessed 5RM bench press. This project examined the interrelationships between power production and upper body kinematics during a series of medicine ball push-press (MBP-P) throws.
