Effects of pole position and grip height on upper-body kinetics and throwing performance in paralympic seated shot put
Purpose This study investigated the effects of pole position (horizontal distance from the seat) and pole grip height on kinetic parameters and throwing performance in Paralympic seated shot put. Methods Four F33–34 athletes (1 national and 3 international levels) each performed 27 maximum-effort throws across nine pole configurations (3 pole positions × 3 grip heights) in a fully crossed within-subject design. Upper-body joint powers and pole fo…
The dynamics of seated shot put
The impact of pole position in seated shot put has been a key research question both in the previous literature and for coaches in the field. The aims of this research were to understand the dynamics of seated shot put and to investigate the impact of changing pole grip height on trunk parameters. Three grip heights are compared: the athlete's standard grip, 75 mm higher than standard, and 75 mm lower than standard, to determine which grip produc…
Relationship between Asymmetry Indices, Anthropometric Parameters, and Physical Fitness in Obese and Non-Obese High School Students
Impaired balance is associated with an increased risk of lower extremity injuries. The purpose of this study was to investigate the relationship between age, anthropometric measurement, and asymmetry index (AI) in an adolescent high school population. Twenty-six male students (15 ± 1.0 years) were randomly selected. Body composition, measurements of vertical jump height using a countermovement jump test (CMJ), and dynamic single stance balance us…
Angular Velocity, Moment, and Power Analysis of the Ankle, Knee, and Hip Joints in the Goalkeeper's Diving Save in Football
The aim of this study was to identify biomechanical characteristics of goalkeeper's diving performance in football. Lower extremity joints powers, moments, and angular velocities, were investigated in seven elite goalkeepers diving to save balls, shot from a ball canon to unanticipated heights (high and low) and sides (right and left). Our result showed that there was a proximal-to-distal sequence for each leg in timing of peak joints powers (p <…
The Effect of Preparatory Posture on Goalkeeper's Diving Save Performance in Football
Identifying the optimal preparatory posture of football goalkeepers can be very relevant for improving goalkeepers' diving save performance, and coaching practices of technical and strength and conditioning coaches. This study aimed to analyse the effect of different starting stance widths and knee flexion angles on movement time, center of mass (CoM) trajectory and velocity in goalkeepers' diving saves. Ten elite goalkeepers performed dives from…
