Using sport science to improve coaching: A case study of Felisha Johnson’s Road to Rio

Abstract

During a shot put, there are different finite variables that can be controlled by the thrower, including release angle, release height, release direction, and release velocity. Previous studies have determined thresholds of release velocity necessary for achieving certain distances, and this case study sought to expand upon that concept. Conclusions from key biomechanical data can make a significant difference in the performance of athletes in the shot put if properly understood by coaches. By utilizing this scientific approach to the shot put event, the throws coach will be able to determine more accurate adjustments and devise training stimuli to better accommodate the athlete. In this case study, researchers and the coach attempted to bridge the gap in the approach to teaching and coaching the glide shot put by using a physics-based equation regarding projectile motion in tandem with biomechanical analyses. The use of immediate feedback via video analysis was an essential part the coaching and teaching system. The athlete’s release angles decreased, and her maximum release velocities increased from 12.5 m/s in 2015 to 13.1 m/s in 2016. This USATF coaching education shot put project is an example in which the cooperation between sport science and coaching helped to produce an Olympic berth (19.24 m) by Felisha Johnson in the women’s shot put in 2016.

Rehabilitation of Knee Injuries in Basketball Players

“…On the one hand, it investigates the severity of knee joint injury and the causes of injury, so as to summarize the situation of knee joint injury; On the other hand, it puts forward effective rehabilitation training and analyzes its sports effect, so as to provide some ideas for the adjustment of athletes' knee joint injury. 7…”

Basketball Course Optimization Based on Mechanical Characteristics

“…At present, China is accelerating from a big sports country to a powerful sports country, with multi-directional development of professional sports, campus sports and mass sports. 2 With the development of basketball, professional sports invent and create more technical actions and sports rules, improve the playability and interest of basketball, and make basketball more competitive; Basketball courses are carried out in Colleges and universities to attract more fans. Through the communication power of colleges and universities, the professional guidance of physical education teachers and the competition among colleges and universities, the activity of basketball projects is maintained and improved; For basketball lovers, while the project is developing, they urgently need to learn the technical movements and theoretical knowledge of basketball.…”

Scientific Training of Athletes’ Core Strength in Competitive Sports

“…The leading strength training methods currently used at home and abroad mainly include the following: unbalanced equipment training, selective training, elastic band training, skateboard training, and rope pulley training. 1 These training belong to the core muscle group strength training that transitions from stable to unstable and functionally restricted conditions. In basketball, endurance strength and fast strength, the two physical strength qualities, have a more obvious effect on competition.…”
