Background: Cheerleading is an emerging and increasingly popular sport among girls. The figures performed during routines require a high level of balance from the athletes. The aim of the study was to analyze the impact of participation in cheerleading classes on body balance in girls during early adolescence. Methods: A total of 35 female cheerleaders from the Power Stars Sząbruk Club (Poland) were divided into three age groups: 8–9 years (n = 15), 10–11 years (n = 11), and 12–14 years (n = 9). Balance assessment was performed using the E.P.S R/1 pedobarographic platform. The Kruskal–Wallis test with Bonferroni post hoc correction was used to analyze intergroup differences in foot load distribution and balance parameters. Results: The analysis revealed statistically significant differences in the pressure on the forefoot area of the right foot (p = 0.007) between the 8–9 and 12–14 age groups, and in the balance level between the youngest group (8–9 years) and the oldest group (12–14 years) at p = 0.028, as well as between the middle group (10–11 years) and the oldest group (p = 0.004). Conclusions: Participation in cheerleading classes may influence the increase in balance, particularly in terms of the distance of center of pressure (C.O.P.) shifts and the average speed of these shifts. In adolescence, muscle development is crucial, and when closely linked with motor coordination, it helps maintain body stability.
