Use of Wrist Guards for Gymnasts – A Systematic Review

ABSTRACT

This systematic review was designed to provide the best current evidence regarding wrist guard use in gymnastics based on relevant biomechanical effects and injury prevention. Evidence supports the use of wrist guards as protective equipment in the prevention of gymnasts’ wrist pain and injury. However, potentially negative effects of wrist guards on proprioception and performance were also reported, and critical gaps in knowledge regarding guard design, most effective indications, and application to female gymnasts remain. Further biomechanical and clinical studies are needed to fill these gaps in knowledge toward making evidence-based recommendations regarding use of wrist guards in gymnastics.

Analyzing Hair Pulling in Athletics

ABSTRACT
This paper investigates biomechanical and ethical issues surrounding long hair in athletics, with a focus on the population of athletes in the National Football League (NFL), the professional organization for American football, who is most affected. Background on the NFL rules regarding player hair length is described. Unlike grabbing a player’s facemask, it is not a penalty to grab and pull hair under certain situations in the NFL. The 2,905 players listed on rosters as of June 2015, are analyzed by their age, NFL units, positions, hair length, and style. Trends in player hair length are illustrated, and it is found that nearly ¾ of players with long hair, defined as long enough to reach their jersey, wear them in a dreadlock style. Three documented case studies of extreme hair pulling incidents by tackling in the NFL are described. A case study of hair tackling in women’s college soccer is also described. An engineering analysis is conducted to estimate the amount of force applied to a player’s hair during an actual NFL hair tackle. The forces are a function of the angle at which the hair is grabbed, and at some angles, the impulsive force applied to a player’s head and neck may exceed 500 pounds. Finally, the ethics behind hair tackles are investigated: both looking at the responsibility of the NFL for its players, as well as player sportsmanship.
