Abstract: In order to study the effects on cardiovascular physiology associated with clothing pressure on human neck, fifteen females were chosen as study subjects. Pressure values of different collar width of high neckline knit shirts were measured. Data of heart rate and blood pressure of each subject were collected in static-dynamic-static state by step test for objective evaluation. The results showed that clothing pressure was correlated with heart rate and blood pressure, and all physiological indicators revealed a remarkable downward trend when the pressure on human neck exceeded 1.2Kpa. Pressure on the neck had the most significant negative impact on cardiovascular system when taking exercises. Pressure on the neck showed more significant effects on systolic blood pressure than diastolic blood pressure in different wearing states, and overpressure would affect human blood pressure recovery after exercises.

Key words: clothing pressure, human neck, cardiovascular, finite element
