Hamstring injury occurrence in elite soccer players after preseason strength training with eccentric overload
TL;DR: The results indicate that addition of specific preseason strength training for the hamstrings – including eccentric overloading – would be beneficial for elite soccer players, both from an injury prevention and from performance enhancement point of view.

Ground reaction forces at different speeds of human walking and running
Johnny Nilsson,Alf Thorstensson +1 more
TL;DR: There is a change with speed in the complex interaction between vertical and horizontal forces needed for propulsion and equilibrium during human locomotion in walking and running.

Force-velocity relations and fiber composition in human knee extensor muscles.
TL;DR: Standardized measurements of dynamic strength of the kneee extensor muscles were performed in 25 healthy male subjects by means of isokinetic contractions, i.e., knee extensions with constant angular velocities, and correlations were demonstrated between peak torque produced at the highest speed of muscle shortening and percent and relative area of fast twitch fibers in the contracting muscle.

Observations on intra-abdominal pressure and patterns of abdominal intra-muscular activity in man.
TL;DR: It appears that transversus abdominis is the abdominal muscle whose activity is most consistently related to changes in intra-abdominal pressure.

Acute First-Time Hamstring Strains During High-Speed Running A Longitudinal Study Including Clinical and Magnetic Resonance Imaging Findings
TL;DR: Careful palpation during the first 3 weeks after injury and magnetic resonance imaging investigation performed during the following 6 weeks provide valuable information that can be used to predict the time to return to pre-injury level of performance in elite sprinting.
