Exercise strength evaluation device

Abstract

To provide an exercise strength estimation device having little possibility of requiring a user for an excessive exercise. An exercise strength estimation device comprises age input means for inputting an age; age designation means for comparing the input age with a lower limit age, to set the lower limit age as an designated age, when the input age is smaller than the lower limit age, and to set the input age as the designated age when not smaller than the lower limit age; target exercise strength input means for inputting a target exercise strength; rest pulse number holding means for holding a rest pulse number; a pulse number sensor for sensing the pulse number; pulse number detecting means for determining a pulse number during the exercise in response to the pulse number sensed; exercise strength operation means for determining the exercise strength during the exercise from the designated age, the rest pulse number and the pulse number during the exercise; exercise strength decision means for deciding whether or not the exercise strength is not less than the target exercise strength; and warning issuing means for issuing a warning in case where the exercise strength is not less than the target exercise strength.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an exercise strength estimation device for evaluating an exercise strength. [0003] 2. Description of the Prior Art [0004] It is known (e.g., Non-Patent Document 1 and Non-Patent Document 2) that the exercise strength is determined by (P−Pr) / (Pmax−Pr). Here: letter P designates a pulse number; letters Pr a rest pulse number; and letters Pmax the maximum pulse number. [0005] It is also known (e.g., Non-Patent Document 2) that the maximum pulse number Pmax is determined by (220−Ag) or (210−α·Ag). Here, letters Ag designates an age, and letter α designates a constant of about 0.8. [0006] It is known (e.g., Patent Document 1, Patent Document 2 and so on) that the aforementioned exercise strength is utilized for exercise strength evaluations in an exercise for health managements, rehabilitations or the like and for an exercise supporting device for training. [0007] In the description thus ...

AI Technical Summary

Benefits of technology

[0015] The exercise strength estimation device of the invention is provided with “the warning issuing means for issuing the warning in case the exercise strength decision means has decided that the exercise strength is not less than the target exercise strength”. As a result, the exercise can be stopped when it reaches the target exercise strength, so that the exercise can be practiced moderate for the health management, the fat prevention, the rehabilitation and so on. The exercise strength estimation device of the invention is provided with not only “the exercise strength operation means for determining the exercise strength while the user is exercising, on the basis of the designated age designated by the age designating means, the rest pulse number held in the rest pulse number holding means, and the pulse number detected by the pulse number detecting means”, but also “the age designation means for comparing the age inputted from the age input means with a lower limit age, to set the lower limit age as an designated age, when the input age is smaller than the lower limit age, and to set the input age as the designated age when the input age is not smaller than the lower limit age”. Even in case, therefore, the age of the user is outside the range in which the correlation to the pulse number has been verified, the device has little possibility of requiring the user for the excessive exercise so that it enables the user to exercise in the state of a high safety.

Problems solved by technology

Therefore, the range may not be proper outside of the age range.

If, therefore, the maximum pulse number is determined by applying the age, which is inputted by a user having an age Ag less than twenty years, as it is, the maximum pulse number may become so excessive that an exercise strength S is underestimated to require the user for a harder exercise than expected, thereby to invite dangers.
