physical information and the health information of the user 200.
The physical activity management system produces 3 levels of
physical fitness, such as low, medium and high levels of physical
fitness, and 12 levels of different target zones. The low, medium
and high levels of physical fitness represent low risk, medium risk
and high risk, and further divided into 8 levels, such as low risk
1 (L1), low risk 2 (L2), medium risk 1 (M1), medium risk 2 (M2),
medium risk 3 (M3), medium risk 4 (M4), high risk (H1), and high
risk 2 (H2), respectively. After inputting the background
information of the user 200 to the receiving unit 204, such as a
wearable device, the background information may be uploaded to a
cloud server, such as the managing unit 206. The cloud server may
evaluate the level of the physical fitness for the user according
to the background information, and set an initial target zone and
an exercise period. For example, a user who has an exercise habit
and no other unhealthy history may be evaluated to have a low risk
physical fitness, target zone 10, and 5 minutes in the exercise
period by the physical activity management system. The physical
activity management system may be, for example, a wearable device,
a cloud server, an APP or any other electronic device, may guide
the user the initial exercise intensity and exercise volume. The
cloud server may provide the user a notice for exercise before
training according to at least one of the physical information, the
health history, the initial exercise intensity and the initial
exercise volume, to guide the user to achieve the health target
zone. The receiving unit 204, the calculating unit 205 and the
managing unit 206 may be in a same device having the receiving,
calculating and guiding function at the same time.
[0034] The target zone may be defined as a zone for the target of
exercise intensity. The exercise intensity may be measured in a
unit of calorie per minute, calorie per hour, calorie per day, MET
(metabolic equivalent of task), Watt, kilometer per minute,
kilometer per hour, kilometer per day, heart rate intensity, heart
rate, speed, respiratory frequency, Borg scale, and so on.
[0035] In one embodiment, the exercise intensity is the heart rate
intensity. If a target of the heart rate intensity is 80%, the
target zone may be 70%-90% in a heart rate reserve (HRR) of a heart
rate intensity calculation system. If the user has an exercise
intensity in the range of 70%-90%, it may regarded as achieving the
target. In general, the heart rate intensity of a high intensity
target zone is in a range of 60%-80%, and the heart rate intensity
of a medium intensity target zone is in a range of 40%-60%. The
heart rate intensity is calculated in the formula (1) and (2)
described below:
Heart rate intensity=[(exercise heart rate-resting heart
rate)/(maximum heart rate-resting heart rate].times.100% (1)
Maximum heart rate=220-age (2)
[0036] The heart rate intensity may be calculated in various
methods. The calculating way for the heart rate intensity of the
disclosure may include various methods.
[0037] The physical activity management system may make a
personalized target zone in suitable exercise intensity, such as a
personalized exercise solution, and help the user exercising in a
more efficient and safer way.

notification unit 210 and the sensing unit 207, respectively.
[0042] In one embodiment, the physical activity management system
60 may be used for managing a physical activity, such as an aerobic
exercise. The ES1 may be a target for the frequency, the intensity,
the type, the time of the physical activity or a combination
thereof.
[0043] In the case that the user 600 uses the physical activity
management system 60 for the first time, the first calculator 605a
may make an exercise solution 1 (ES1) for the user 600 according to

rate of the exercise intensity detected in a physical activity
management system according to an embodiment of the disclosure.
[0052] Referring to FIG. 9, a target of an exercise intensity G
(such as heart rate intensity) may be set to be 70%. If the user
600 has the exercise intensity G equal to or higher than 70%, the
target of the exercise intensity G is reached. During an exercise
period of 30 minutes, the heart rate intensity G is detected and
recorded by the sensing unit 607. A ratio of the time reaching the
target of the exercise intensity to the exercise period is
calculated, and the achieving rate of the exercise intensity H is
produced. For example, the user has 22 minutes in reaching the
target of the exercise intensity G during the exercise period of 30
minutes, and the achieving rate of the exercise intensity H is
22/30, which equals to 0.733. In the present embodiment, the target
of the exercise intensity is 70% and the target of the exercise
period is 30 minute. However, the scope of the disclosure is not
limited thereto. The target of the exercise intensity may be any
other value according to the demands for different users, such as
50%, 60% or 80%. The target of the exercise period may also be any
other time period according to the demands for different users,
such as 25 minutes, 40 minutes and 60 minutes.
[0053] FIG. 10 shows an exemplified heart rate recovery detected in
a physical activity management system according to an embodiment of
the disclosure.
[0054] Referring to FIG. 10, the sensing unit 607 still detects the
heart rate when the user stops exercising. The calculating unit
605, such as the second calculator 605b, produce the heart rate
recovery R according to the heart rate detected by the sensing unit
607. The time point of 30th minutes corresponds to a first point of
the heart rate, such as 154, and the time point of 31th minutes
corresponds to a second point of the heart rate, such as 133. Three
points, such as the first point, the second point, and an
intersection point of a vertical extension line from the first
point and a horizontal extension line from the second point, may
form a right triangle. In the right triangle, the heart rate
recovery R is defined as a ratio of an angle .theta..sub.1
corresponding to the second point to 90 degrees, such as 70/90,
which equals to 0.778. The angle .theta..sub.1 is defined as the
following formula:
.theta. 1 = tan - 1 ( HR t 31 - HR t 30 t 31 - t 30 )
##EQU00001##
[0055] The t.sub.30 indicates the time point at 30 minutes,
t.sub.31 indicates the time point at 31 minutes, HR.sub.t30
indicates the heart rate at 30.sup.th minutes, and HR.sub.t31
indicates the heart rate at 30.sup.th minutes.
[0056] In general, the angle .theta..sub.1 is defined as the
following formula:
.theta. 1 = tan - 1 ( HR t q - HR t q - 1 t q - t q - 1 )
##EQU00002##
[0057] The t.sub.q-1 indicates the time point at q-1.sup.th
minutes, t.sub.q indicates the time point at q.sup.th minutes,
HR.sub.t.sub.q-1 indicates the heart rate at q-1.sup.th minutes,
and HR.sub.t.sub.q indicates the heart rate at q.sup.th
minutes.
[0058] FIG. 11 shows an exemplified respiratory rate recovery
detected in a physical activity management system according to an
embodiment of the disclosure.
[0059] Referring to FIG. 11, the sensing unit 607 still detects the
respiratory frequency, such as the breathing or panting numbers per
minute, when the user stops exercising. The calculating unit 605,
such as the second calculator 605b, produce the respiratory rate
recovery B according to the respiratory frequency detected by the
sensing unit 607. The time point of 30th minutes corresponds to a
first point of the breathing numbers, such as 45, and the time
point of 31th minutes corresponds to a second point of the
respiratory frequency, such as 40. Three points, such as the first
point, the second points and an intersection point of a vertical
extension line from the first point and a horizontal extension line
from the second point, may form a right triangle. In the right
triangle, the respiratory rate recovery B is defined as a ratio of
an angle .theta..sub.2 corresponding to the second point to 90
degrees, such as 50/90, which equals to 0.556. The angle
.theta..sub.2 is defined as the following formula:
.theta. 2 = tan - 1 ( BR t 31 - BR t 30 t 31 - t 30 )
##EQU00003##
[0060] The t.sub.30 indicates the time point at 30 minutes,
t.sub.31 indicates the time point at 31 minutes, BR.sub.t30
indicates the respiratory frequency at 30.sup.th minutes, and
BR.sub.t31 indicates the respiratory frequency at 30.sup.th
minutes.
[0061] In general, the angle .theta..sub.2 is defined as the
following formula:
.theta. 2 = tan - 1 ( BR t q - BR t q - 1 t q - t q - 1 )
##EQU00004##
[0062] The t.sub.q-1 indicates the time point at q-1.sup.th
minutes, t.sub.q indicates the time point at q.sup.th minutes,
BR.sub.t.sub.q-1 indicates the respiratory frequency at q-1.sup.th
minutes, and BR.sub.t.sub.q indicates the respiratory frequency at
q.sup.th minutes.
[0063] For example, a first target of the exercise intensity in the
ES1 may be modified to a second target of the exercise intensity in
the ES2 according to the adjustment decision. The adjustment
decision for the target of the exercise intensity G may be
calculated according to the achieving rate of the heart rate
intensity H, the heart rate recovery R, and the respiratory rate
recovery B.
[0064] The target of the exercise intensity G may be modified
according to the following formula:
G.sub.i=G.sub.i-1+.DELTA.G.sub.i; G.sub.i.ltoreq.1
[0065] G.sub.i is the target of the exercise intensity at the
i.sub.th time, G.sub.i-1 is the target of the exercise intensity at
the i-1.sub.th time, .DELTA.G, is an adjustment decision for the
target of the exercise intensity at the i.sub.th time.
[0066] G.sub.0 is an initial target of the exercise intensity given
by a doctor or calculated by the physical activity management
system according to the background information of the user.
.DELTA.G.sub.i=.DELTA.H.sub.i+.DELTA.R.sub.i+.DELTA.B.sub.i
.DELTA.H.sub.i=H.sub.i-H.sub.i-1; H.sub.i.ltoreq.1
.DELTA.R.sub.i=R.sub.i-R.sub.i-1; R.sub.0=R.sub.1
.DELTA.B.sub.i=B.sub.i-B.sub.i-1; B.sub.0=B.sub.1
[0067] .DELTA.H.sub.i is a difference between the achieving rate of
the heart rate at the i.sub.th time and the achieving rate of the
heart rate at the i-1.sub.th time.
[0068] .DELTA.R.sub.i is a difference between the heart rate
recovery at the i.sub.th time and the heart rate recovery at the
i-1.sub.th time. R.sub.0 is an initial heart rate recovery. R.sub.1
is a heart rate recovery at the first time.
[0069] .DELTA.B.sub.i is a difference between the respiratory rate
recovery at the i.sub.th time and the respiratory rate recovery at
the i-1.sub.th time. B.sub.0 is an initial respiratory rate
recovery. B.sub.1 is a respiratory rate recovery at the first
time.
[0070] In brief, the physical activity management system may keep
detecting, calculating and coaching the user for exercising. That
is, the physical activity management system may keep comparing the
exercise status at the i.sub.th time (including H.sub.i, R.sub.i
and B.sub.i) and the target value at the i-1.sub.th time (including
H.sub.i-1, R.sub.i-1, and B.sub.i-1), to get the adjustment
decision at the i.sub.th time .DELTA.G.sub.1, and using the
.DELTA.G.sub.1 and G.sub.i-1 to determine the target exercise
intensity for the next time G.sub.i. The adjustment decision
.DELTA.G.sub.i at the i.sub.th time is a value related to
differences between the exercise status at the i.sub.th time
(including H.sub.i, R.sub.i and B.sub.i) and the target value at
the i-1.sub.th time (including H.sub.i-1, R.sub.i-1 and B.sub.i-1).
In other words, the calculating unit 605 makes the adjustment
decision .DELTA.G.sub.i by comparing an achieving rate of heart
rate in the exercise status H.sub.i, and an achieving rate of heart
rate in the first exercise solution H.sub.i-1, comparing the heart
rate recovery in the exercise status R.sub.i and a heart rate
recovery in the first exercise status R.sub.i-1, and comparing the
respiratory rate recovery in the exercise status B.sub.i and a
respiratory rate recovery in the first exercise solution
B.sub.i-1.
[0071] In one embodiment, a user A set the target of the exercise
intensity G.sub.0 as 0.7, such as reaching 70% of the maximal heart
rate, and the achieving rate of the exercise intensity H.sub.0 as
0.5 in a physical activity management system which may calculate
the formula described above. Then, the user A wears the device
including the physical activity management system to do exercise,
and the physical activity management system may detect the exercise
status of the user A, such as the achieving rate of the exercise
intensity at the first time H.sub.1, the heart rate recovery at the
first time R.sub.1 and the respiratory rate recovery at the first
time B.sub.1, which are 0.33, 0.84 and 0.87, respectively. The
physical activity management system may also calculate the
adjustment decision at the first time .DELTA.G.sub.1 by comparing
the exercise status at the first time (including H.sub.1, R.sub.1
and B.sub.1) and the initial value including H.sub.0, R.sub.0 and
B.sub.0. For example,
.DELTA.G.sub.1=(0.33-0.5)+(0.84-0.84)+(0.87-0.87)=-0.17. The target
of the exercise intensity for the next time G.sub.1 may be a
modified according to the adjustment decision at the first time
.DELTA.G.sub.1, and G.sub.1=0.7-0.17=0.53. At the second time of
exercising, if the physical activity management system detects that
the achieving rate of the exercise intensity at the second time
H.sub.2, the heart rate recovery at the second time R.sub.2 and the
respiratory rate recovery B.sub.2 at the second time of the user A
are 0.33, 0.84 and 0.87, respectively, then the physical activity
management system may also calculate the adjustment decision at the
second time .DELTA.G.sub.2. For example,
.DELTA.G.sub.2=(0.45-0.33)+(0.83-0.84)+(0.86-0.87)=0.10. The target
of the exercise intensity for the next time G.sub.2 may be a
modified according to the adjustment decision at the second time
.DELTA.G.sub.2, and G.sub.2=0.53+0.10=0.63.
[0072] In one embodiment, a user B set the target of the exercise
intensity G.sub.0 as 0.6, such as reaching 60% of the maximal heart
rate, and the achieving rate of the exercise intensity H.sub.0 as
0.3 in a physical activity management system which may calculate
the formula described above. Then, the user B wears the device
including the physical activity management system to do exercise,
and the physical activity management system may detect the exercise
status of the user B, such as the achieving rate of the exercise
intensity at the first time H.sub.1, the heart rate recovery at the
first time R.sub.1 and the respiratory rate recovery at the first
time B.sub.1, which are 0.9, 0.92 and 0.89, respectively. The
physical activity management system may also calculate the
adjustment decision at the first time .DELTA.G.sub.1 by comparing
the exercise status at the first time (including H.sub.1, R.sub.1
and B.sub.1) and the initial value including H.sub.0, R.sub.0 and
B.sub.0. For example,
.DELTA.G.sub.1=(0.9-0.3)+(0.92-0.92)+(0.89-0.89)=0.6. The target of
the exercise intensity for the next time G.sub.1 may be a modified
according to the adjustment decision at the first time
.DELTA.G.sub.1, and G.sub.1=0.6+0.6=1.2. Since G.sub.1.ltoreq.1,
G.sub.1 is determined to be 1. Then, the physical activity
management system may keep detecting, calculating and coaching the
user B in the following exercise procedure. At the second time of
exercising, if the physical activity management system detects that
the achieving rate of the exercise intensity at the second time
H.sub.2, the heart rate recovery at the second time R.sub.2 and the
respiratory rate recovery B.sub.2 at the second time of the user B
are 0.85, 0.89 and 0.86, respectively, then the physical activity
management system may also calculate the adjustment decision at the
second time .DELTA.G.sub.2. For example,
.DELTA.G.sub.2=(0.85-0.9)+(0.89-0.92)+(0.86-0.89)=-0.11. The target
of the exercise intensity for the next time G.sub.2 may be a
modified according to the adjustment decision at the second time
.DELTA.G.sub.2, and G.sub.2=1+(-0.11)=0.89.
[0073] The method for calculating the adjustment decision is not
limited thereto. Any related method calculating with the G, H, R
and B may be included in the scope of the disclosure.
[0074] In one embodiment, the exercise intensity G may be a heart
rate intensity, and the achieving rate of the exercise intensity
may be the achieving rate of the heart rate intensity.
[0075] In an embodiment, the present application provides a
physical activity management system using the exercise intensity G,
the achieving rate of the exercise intensity H, the heart rate
recovery R, and the respiratory rate recovery B to analyze if the
exercise solution is suitable for the user or not, and making an
adjustment decision to modify the exercise solution. That is, a
personalized exercise solution may be provided. Since the
parameters for the adjustment decision includes the respiratory
rate recovery B by using the sonic frequency sensing unit to detect
the respiration of the user, the evaluation to the exercise status
of the user may be more accurate comparing to merely using the
feeling of the user in Borg scale to evaluate the exercise status.
In this way, the physical activity management system of present
application may coach the exercise solution for the user in a
personalized way, and the user may get a health goal, such as,
controlling the blood pressure, the blood sugar, the blood fat, the
weight, or the waist circumference, improving the bone density and
the depression, in a more efficient and safer way.
[0076] In summary, the physical activity management system
disclosed in aforementioned embodiments may use multiple parameters
including the exercise intensity, the achieving rate of the
exercise intensity, the heart rate recovery, and the respiratory
rate recovery to analyze if an exercise solution is suitable for
the user or not, and making an adjustment decision to modify the
exercise solution. That is, a personalized exercise solution may be
provided. Since the parameters for the adjustment decision includes
the respiratory rate recovery by using a sonic frequency sensing
unit to detect the respiration of the user, the evaluation to the
exercise status of the user may be more accurate comparing to
merely using the feeling of the user in Borg scale to evaluate the
exercise status. In this way, the physical activity management
system of present application may coach the exercise solution for
the user in a personalized way.
[0077] It will be apparent to those skilled in the art that various
modifications and variations may be made to the disclosed
embodiments. It is intended that the specification and examples be
considered as exemplary only, with a true scope of the disclosure
being indicated by the following claims and their equivalents.
