Sprint Performance Following Plyometric Conditioning Activity In Elite Sprinters, Michal Krzysztofik, Mateusz Jopek, Dariusz Mroczek, Aleksander Matusiński, Adam Zając

Introduction: Considering the significance of the ankle joint for sprinting with the spring-like properties of the Achilles tendon, it seems that plyometric activating exercises could significantly potentiate maximum velocity sprinting. Therefore, the objective of this study was to evaluate the effects of specific plyometric exercises engaging the ankle joint, called stiff-legged hops as a conditioning activity (CA) on countermovement jump (CMJ) and sprinting performance evaluated over a distance of 50m in elite female and male sprinters that differ in athletics level. Material and methods: Thirty-two sprinters of the Polish National Team were assigned into experimental and control (CTRL) groups, while …
Effects Of Semi-Custom And Off-The-Shelf Orthoses On Achilles Tendon And Patellofemoral Kinetics In Female Runners, Jonathan Sinclair, Jim D. Richards, Hannah Shore
Effects Of Semi-Custom And Off-The-Shelf Orthoses On Achilles Tendon And Patellofemoral Kinetics In Female Runners, Jonathan Sinclair, Jim D. Richards, Hannah Shore

Background: The aim of the current investigation was to examine the effects of semi-custom and off-the-shelf orthotics on the loads experienced by the patellofemoral joint and the Achilles tendon in female runners. Material and Methods: Twelve female recreational runners ran at 4.0 m.s‑1 whilst wearing no orthotics, semi-custom orthotics and off-the-shelf orthotics. Kinetics and kinematics of running were obtained via a force platform and a motion capture system. Differences between orthotic conditions were contrasted using one-way repeated measures ANOVA. Results: The results showed that both patellofemoral contact force and pressure were significantly lower in the no-orthotic (force = 3.21 B.W …
Gender Differences In The Achilles Tendon Load During The Fencing Lunge, Jonathan Kenneth Sinclair, Lindsay Bottoms
Gender Differences In The Achilles Tendon Load During The Fencing Lunge, Jonathan Kenneth Sinclair, Lindsay Bottoms
Baltic Journal of Health and Physical Activity
Background: Recent epidemiological analyses in fencing have shown that injuries and pain linked specifically to fencing training/competition were evident in 92.8% of fencers. Specifically the prevalence of Achilles tendon pathology has increased substantially in recent years, and males have been identified as being at greater risk of Achilles tendon injury compared to their female counterparts. This study aimed to examine gender differences in Achilles tendon loading during the fencing lunge. Material/Methods: Achilles tendon load was obtained from eight male and eight female club level epee fencers using a 3D motion capture system and force platform information as they completed simulated …
A Randomized Clinical Trial To Compare The Effect Of Non Operative Treatment With And Without Autologous Conditioned Plasma (Acp) On Healing And Function In Patients With Achilles Tendon Ruptures, Tyler M. Pratt
Electronic Thesis and Dissertation Repository
The purpose of this study was to determine whether there is evidence to support conducting a larger randomized control trial (RCT) to compare the non-operative treatment of Achilles tendon (AT) ruptures with or without Autologous Conditioned Plasma (ACP®). Twenty-four patients were randomized to receive an ACP® or saline injection within seven days and again at two weeks post-rupture. Tendon healing was longitudinally evaluated using ultrasound (US) and magnetic resonance imaging (MRI). Functional and patient-reported quality of life measures were also assessed. A small sample size limited our ability to detect statistically significant differences. The mean rankings of healing were slightly …
