Objective:　Students＇　physical　fitness　is　declining,　which　highlights　the　urgent　need　for　physical　education　to　solve　the　students＇　physical　and　health　problems.　Physical　education　is　an　important　part　of　students＇　physical　exercise.　In　this　study,　a　high　school　students　perform　a　real-time　monitoring　of　heart　rate　in　the　physical　education,　through　the　comprehensive　evaluation　of　exercise　intensity　and　exercise　duration　to　understand　the　exercise　load　of　physical　education.　Methods:　The　whole　motion　intensity　is　divided　into　three　levels:　low　intensity　exercise,　medium　intensity　exercise　and　high　intensity　exercise　(including　extra　high　intensity　exercise)　according　to　the　motion　of　the　heart　rate　collected.　Then　the　movement　time　of　each　intensity　exercise　was　calculated.　The　exercise　was　scored　according　to　the　established　evaluation　criteria.　In　this　study,　we　evaluated　the　exercise　load　from　two　aspects:　exercise　intensity　and　duration.　Results:　By　monitoring　the　movement　of　heart　rate　and　duration,　in　the　same　class,　due　to　the　different　levels　of　effort,　the　effect　of　the　movement　of　the　students　are　different　in　spite　of　the　movement　ability　of　the　students　are　close　to.　Conclusion:　By　monitoring　the　heart　rate　and　movement　duration,　students　daily　exercise　quantitative　scores.　The　score　visual　feedbacks　each　students＇　daily　exercise　load　and　provides　objective　basis　and　instruction　for　physical　education　teachers,　schools　and　the　relevant　administrative　departments.
