Figure 5 The measured contraction forces (CF) after exposure to infrasound were negatively corresponded to Infrasound_level measured in dBz (P = 0.018). The CF%_test decreased almost 11% against the CF%_cont at 110 dBz and 18% at 120 dBz. Exposure to infrasound did not alter the contraction duration (CD) in any group (P = 0.765).
