Does fatigue influence joint-specific work and ground force production during the first steps of maximal acceleration?

During initial acceleration, the first steps of a maximal-effort (sprint) run often determine success or failure in the capture and evasion of an opponent, and is therefore a vital factor of success in many modern sports. However, accelerative events are commonly performed after having already run considerable distances, and the associated fatigue should impair muscle force production and thus reduce acceleration. Despite this, the effects of running-induced fatigue on our ability to accelerate as well as the running technique used to achieve it have received little attention.

Reassessing the disability divide: unequal access as the world is pushed online.

In a time when a global pandemic has forced people to use technology for almost every aspect of their day-to-day lives, it is important to determine if specific disadvantaged groups are appropriately connected to the digital world. This paper attempts to assess whether people with disabilities (PWD) own computers, connect to the Internet, and participate in online activities at the same rates as the general population. Using comprehensive data from the 2017 Current Population Survey we find that PWD still lag behind in computer ownership and Internet access.

Partially retained small finger flexor digitorum profundus function despite complete tendon loss in the forearm.

A case of traumatic laceration of the small finger flexor digitorum profundus (FDP) tendon in the distal forearm with retained partial active flexion at the small finger distal interphalangeal joint (DIP) joint is described. Tendinous interconnections between the ring and small FDP tendons and lumbrical muscles may permit partial FDP function at the DIP joint despite a complete deficit of the proximal tendon.
