A biometric information presentation system that enables efficient training by obtaining biometric information without giving a subject a sense of discomfort. The biometric information presentation system uses a garment-type biometric information measuring apparatus including at least fabric having a 20% elongation stress of 20 N or less. A garment pressure of the garment-type biometric information measuring apparatus is 0.1 kPa or more and 1.5 kPa or less. A skin contact-type electrode is provided at a portion of the garment-type biometric information measuring apparatus at which a garment pressure is 0.3 kPa or more. The garment-type biometric information measuring apparatus is worn by the subject. From obtained electrocardiographic information is calculated an RRI, an indicator of parasympathetic activity and indicator of sympathetic activity. The biometric information presentation system presents this calculated result on a terminal device and presents an action based upon the result to achieve the efficient training.
