* p < 0.05: significant difference between PRE and POST,
# p < 0.05: significant difference between POST and 30 min PRE, before foam rolling intervention; POST, 2 min after foam rolling intervention; 30 min, 30 min after foam rolling intervention; DF ROM: dorsiflexion range of motion; MG: medial gastrocnemius, MVIC, maximum voluntary isometric contraction. Data presented as mean ± standard deviation.
