[Evaluation of sub-maximal aerobic capacity level determined by double product break point (DPBP) among Japanese adults].

Objectives: The purpose of this study was to determine sub-maximal aerobic capacity levels evaluated by metabolic equivalents (unit is METs) at the double product break point (DPBP) and elucidate the safe and effective average exercise intensity among Japanese adults. A total of 438 subjects (123 males and 315 females) who participated in the exercise prescription course with measurement of the DPBP during a continuous incremental exercise test with a bicycle

Methods: ergometer were enrolled in this study. The DP (heart rate-systolic blood pressure product) featured rapid increase with increasing exercise load during the continuous incremental exercise test.
