The Healing Power of Sport report is one of the first studies to assess ways in which sports participation during the coronavirus pandemic (COVID-19) may have buffered girls from the detrimental impacts of the pandemic on youth physical health behaviors, psychological well-being, and academic engagement and achievement. To gain a better understanding of the landscape of girls' sports during the pandemic, the current report first set out to examine whether there were observed declines in girls' sports participation during the first full year of the pandemic (2021) when compared to prior to school years before the pandemic began (i.e., 2019 through first quarter 2020), and whether COVID-19 exacerbated pre-existing gender disparities in youth sports participation with consideration of differences between boys' and girls' participation by race/ethnicity, socioeconomic status (i.e., parent education), urbanicity, and youth grade level. The current report then examined whether participation in sports during the pandemic was related to girls' and boys' physical and mental health and academic outcomes, with a particular focus on the impact for girls. Given youth reap the greatest benefits from their participation when they are engaged in two or more sports across the year, the report considered differences between girls who were able to maintain their participation in multiple sports (at least two sports) during the pandemic compared to those who participated in one sport and their non-participating peers. To accomplish this objective, the Women's Sports Foundation (WSF) used cross-sectional data from the 2019, 2020, and 2021 Monitoring the Future (MTF) study of eighth-, 10th-, and 12th-grade students. The MTF study is an annual self-administered (pen and paper or electronic tablet) survey conducted with nationally representative samples of eighth-, 10th-, and 12th-grade students in U.S. secondary schools in the United States. The 12th-grade sample has been collected since 1975, and the eighth- and 10th-grade samples have been collected since 1991. This study used a partial sample of eighth, 10th and 12th graders who were randomly selected to answer questions on participation in 21 different types of competitive sports (2010 was the first year to include an expanded list of competitive sports). Thus, The Monitoring the Future (MTF) dataset provides cross-sectional samples of eighth-, 10th- and 12th-grade students who participated in surveys prior (i.e., 2019 and 2020) and during (i.e., 2021) COVID-19 and provides a unique opportunity to assess several important questions about girls' participation in sports during a global crisis.
