A Sprinter and a Long-Distance Runner
Physiologically, long distance athletes are lean which is ideal for covering the ground. They are also tall with long arms and legs that provides extra strength for making bigger strides. Sprinters, on the other hand, are solidly built and explosively fast which suits them for shorter stretches. They are typically quicker than distance runners which helps them to build up quickly. Contrary, lengthy-distance racers have extensive, slim muscles specifically on the lower body while sprinters have stronger muscles on the upper bodies (Billat, 2001). Sprinters muscles are characterized by more fast-twitch fibers hence making the muscle to be larger.
Notably, it is difficult for an Olympic-level competitive sprinter to become a competitive marathon athlete. This is because there are specific entry requirements for both the distant and short runners. Therefore, sprinters are better suited for 100m or less while long sprinters can do more and longer running distances. This is guided by the perception that, running depends on the miles that athletes continuously practice hence they are calibrated for the right dose.

NFL Concussion Protocol
The NFL’s concussion protocol was established and administered mutually with the NFL Players Association. It was designed due to the violent nature of NFL, hence the need to assess whether the player has suffered a concussion or not. Recently, this intention has been criticized for not being effective since players who sustained a concussion during the match were permitted to continue playing. The potential consequences of these concussions entail brain damage and vestibular dysfunction. In that, it affects the movement and stability by damaging the vestibular system hence ends up causing vertigo and dizziness among other complications (Goodman, Vargas, & Dodick, 2013).
Therefore, the current NFL protocols have to be changed to respond to the intricacies associated with concussions. NFL protocols hold that if a player is hit he should be removed from the filed immediately for further assessments but in most cases, this does not happen. The NFL needs to take charge and enhance safer matches as well as to design helmets that genuinely keeps the players brains safe from any injuries. Subsequently, children below the age of twelve should not be allowed to play NFL since they will develop cognitive and behavioral complications later on in life (Belson, 2017). In that, their brains are still growing hence the need to avoid repetitive head impacts.
