Description
The purpose of this study was to determine if there were asymmetries in ground reaction forces (GRF) between dancers and non-dancers, and to see the effect of GRF on external (ER) and internal rotator (IR) strength. Subjects performed double- and single-legged jumps on a force plate with a motion capture

The purpose of this study was to determine if there were asymmetries in ground reaction forces (GRF) between dancers and non-dancers, and to see the effect of GRF on external (ER) and internal rotator (IR) strength. Subjects performed double- and single-legged jumps on a force plate with a motion capture marker system attached at anatomical landmarks, and then had strength and range of motion (ROM) of their internal and external rotators tested along at degrees of hip flexion. There were no significant differences in GRF between legs for all subjects involved. However, stronger hip ER was negatively correlated with vertical GRF (z-axis), positively correlated with anteroposterior (y-axis) GRF, and higher mediolateral (x-axis) GRF from double-leg trials was positively correlated with knee abduction. Thus, future studies should further investigate GRF broken into axial components as well as the time to peak GRF to determine any relation of these factors to knee valgus and ACL injury risk.

This project was designed to evaluate a nutrition educational tool designated to educate high school dancers about the importance of nutrition through collecting feedback from dancers during focus group discussions. The nutrition educational tool was created to be easy to read and understand, while still informing on important topics such as water intake, sleep, food groups, diets, and meal prepping. After giving a presentation of the tool to a group of high school dancers, eleven students from a high school dance team completed a survey answering questions about the tool and then participated in a group discussion that asked guided questions about their perceptions of the material presented and their suggestions for edits. Results showed that overall, the participants found this tool useful, but suggested improvements include missing information on the sleep requirement section, more suggestions for dietary restrictions, and additional details about foods and meal prepping. Overall, students found this tool useful for themselves, but results were mixed about if they would use this information in the future or share it with others. Nutrition is an important topic for high school athletes, especially dancers, and should be taught in order to keep dancers healthy.
