This study aimed to determine whether 8 weeks of a core strength training program with three sessions weekly can improve cyclists’ core muscle strength. Six healthy male junior cyclists (age 15.8 ± 1 years, mass 62 ± 4 kg, height 170.2 ± 6 cm) volunteered for the study. Participants were instructed to perform five types of core exercises per session for a total of 24 sessions. For every session, each movement was performed in 20 repetitions for three sets. Comparison of preand post-test data revealed significantly greater (p < 0.05) gains in this case study. These results suggest that it is important for coaches to incorporate core strengthening exercises in their training routines
