Ground reaction forces (GRF) are associated with bone hypertrophy; therefore, they are important to understanding physical activity’s role in children’s bone health. In this study, we examined the ability of accelerometry to predict vertical GRF in 40 children (mean age 8.6 yr) during slow walking, brisk walking, running, and jumping. Correlation coefficients between accelerometry-derived movement counts and GRF were moderate to high and significant during walking and running, but not during jumping. Given a large proportion of children’s daily physical activity involves ambulation, accelerometry should be useful as a research method in bone-related research. However, this method underestimates GRF during jumping, an important physical activity for bone modeling and remodeling.

Based on a true story, Glory Road recounts the story of the 1966 national championship Texas Western College basketball team and coach Don Haskins' decision to start, for the first time in tournament history, five black players. Contextualized by sociologist Patricia Hill Collins' concept of "new racism," this article argues that filmmakers manipulated history in order to inflate Haskins' progressive convictions by omitting, augmenting, and fabricating pivotal events in the historical narrative. These ultimately pronounce a white savior at the center of history and marginalize black athletes, even in a story that ostensibly deals with their struggles for racial equality.

the 2002 U.S. Open, Serena Williams received a great deal of attention for wearing an outfit described as "a body-clinging, faux leather, black cat-suit." It was not necessarily the catsuit itself that the popular media found especially controversial but rather the visibility of her physique the outfit provided. The ways in which Serena Williams, the outfit, and her body were discussed offers a particular site at which to interrogate the production of blackness in 21st-century, U.S. society. This article argues that the processes of differentiation the popular media used to characterize her are located within racialized discourse. By representing Williams through oppositional rhetorics, that is, setting her multiple identities in contradistinction to other women on the tour, accounts concerning her appearance in the catsuit reproduce the hegemonic racialized order in women's tennis.
