Abstract: The investment in learning required to reach benefit with weightlifting training is currently not well understood in elite athletes. The purpose of this investigation was to quantify changes in vertical jump power production and kinematic variables in hang power clean (HPC) performance during the learning process from a naive state in a multiple single-subject research design. Four elite athletes undertook HPC learning for approximately 20-30 minutes twice per week over a 169-day period. Changes in parameters of vertical power production during squat jump (SJ) and countermovement jump (CMJ) were monitored from baseline (day 0) and at 3 additional occasions. Hang power clean movement kinematics and bar path traces were monitored from day 35 and at 3 additional occasions particular to the individual's periodized training plan. Descriptive statistics were reported within athletes as mean ± SD. We observed a 14.1-35.7% (SJ) and a -14.4 to 20.5% (CMJ) gain in peak power across the 4 jump testing occasions with improvements over the first 4 weeks (SJ: 9.2-32.6%; CMJ: -2.91 to 20.79%). Changes in HPC movement kinematics and barbell path traces occurred for each athlete indicating a more rearward-directed center of pressure over the concentric phase, greater double knee bend during the transition phase, decreased maximal plantar flexion, and minimal vertical displacement of body mass with HPC learning. Considering the minimal investment of 4 weeks to achieve increases in vertical power production, the benefits of training with HPC justified the associated time costs for these 4 elite athletes.

Comparison of the Hang High Pull and Loaded Jump Squat for the Development of Vertical Jump and Isometric Force-Time Characteristics.
TL;DR: Loaded jumps seem equally effective as weightlifting derivatives for improving lower-body power in experienced athletes and loaded jumps should be considered where coaching complex movements is difficult.

Haizhen Li,Baojun Zhang +1 more
TL;DR: Based on binocular stereo vision measurement and wireless sensing theory, a noncontact displacement measurement system was developed in this article, which uses template matching to extract the image coordinates of the measurement points and restore the spatial coordinates of measurement points through European 3D reconstruction.

Differences in End Range of Motion Vertical Jump Kinetic and Kinematic Strategies Between Trained Weightlifters and Elite Short Track Speed Skaters
TL;DR: The findings suggest that the end ROM kinetic and kinematic strategy used during jumping is group-specific in power-trained athletes, with WL exhibiting superior strategies as compared with resistance- and jump-trained STSS.

Developing maximal neuromuscular power: part 2 - training considerations for improving maximal power production.
TL;DR: This series of reviews focuses on the most important neuromuscular function in many sport performances, the ability to generate maximal muscular power, and the factors that affect maximal power production.
An optimal control model for maximum-height human jumping
TL;DR: Qualitative comparisons between the predictions of the model and previously reported experimental findings indicate that the model reproduces the major features of a maximum-height squat jump, including limb-segmental angular displacements, vertical and horizontal ground reaction forces, sequence of muscular activity, overall jump height, and final lift-off time.

Adaptations in athletic performance after ballistic power versus strength training.
TL;DR: The ability of strength training to render similar short-term improvements in athletic performance as ballistic power training, coupled with the potential long-term benefits of improved maximal strength, makes strength training a more effective training modality for relatively weak individuals.

Kinematics, Kinetics, and Muscle Activation during Explosive Upper Body Movements
TL;DR: It was concluded that performing traditional press movements rapidly with light loads does not create ideal loading conditions for the neuromuscular system with regard to explosive strength production, especially in the final stages of the movement.
