When the user terminal 20 is connected to the management server 10, a user information input screen is displayed.

FIG. 4 is an example of a user information input screen of the user terminal 20. As shown in FIG. As shown in FIG. 4, the user information input screen includes a physical information input screen 101 (FIG. 4A) and a game information input screen 102 (FIG. 4B). As shown in FIG. 4A, the physical information input screen 101 is provided with an input field 110 for a user ID and input fields 111a to 111d for user's height, weight, sex, date of birth, etc. . On the physical information input screen 101, the user inputs the user ID in the input field 110, and inputs physical information such as the user's height, weight, sex, and date of birth in the input fields 111a to 111d.

As shown in FIG. 4B, the game information input screen 102 is provided with input fields 112a to 112c for the game event, period division, amount of exercise, etc., and a button 113. As shown in FIG. The user inputs the game information such as the game event, division into periods, amount of exercise, etc. in the input fields 112a to 112c.

When physical information and game information are input to the user terminal 20 by the user's operation, the user's physical information and game information are sent to the management server 10 via the network 40 . When the management server 10 receives the user's physical information and game information from the user terminal 20 , the management server 10 saves this information in the recommended nutritional intake database 30 .

In addition, when the management server 10 stores the user's physical information and the game information in the recommended amount of nutrition intake database 30, the management server 10 processes the user's physical information and the game information, and stores the recommended amount of nutrition intake database 30 You can also save to . For example, as shown in FIG. 4A, the information entered in the input field 111d is the date of birth of the user. Send to the reference dose database 30. Thus, as shown in FIG. 2, the recommended intake database 30 has an item of age.
Further, as shown in FIG. 4(B), the information input in the input field 112a is the user's sports event, but the management server 10 classifies the sports from the sports event, send to database 30; As a result, as shown in FIG. 2, the recommended nutritional intake database 30 has items for sport classifications such as explosive type and ball game type. The physical information and the game information may be processed on the side of the recommended intake amount database 30 .

When the user touches the button 113 stating "Acquire the recommended amount of nutritional intake", the user terminal 20 sends information requesting the management server 10 to acquire the recommended amount of nutritional intake (nutrition A request for acquisition of the recommended amount of intake) is sent.
When the management server 10 receives the recommended amount of nutritional intake acquisition request from the user terminal 20, the management server 10 retrieves the physical information and the competition information corresponding to the user ID that transmitted the recommended amount of nutritional intake acquisition request from the database 30 of the recommended amount of nutritional intake. get.
Then, the recommended amount of nutritional intake calculation unit 12 of the management server 10 uses information included in the physical information and the game information to calculate the recommended amount of nutritional intake of the user.

Here, a method for calculating the recommended amount of nutritional intake by the calculation unit 12 for calculating the recommended amount of nutritional intake will be described.
The recommended amount of nutritional intake calculation unit 12 calculates the recommended amount of nutritional intake based on the information of each item included in the physical information and the information of each item included in the game information.

The recommended intake amount calculation unit 12 calculates a reference recommended intake amount (reference recommended intake amount) based on the weight and basal metabolic rate of the user. The basal metabolic rate is the amount of energy per unit weight required for the user to sustain life, which is determined based on information such as the user's sex, age, and muscle mass. The reference intake calculation unit 12 multiplies the basal metabolic rate by the body weight of the user to calculate the total amount of energy necessary for the user to sustain life, and based on the calculated total amount of energy to calculate the standard recommended intake. By calculating the standard recommended intake based on body weight and basal metabolic rate in this way, at least the intake required to sustain life can be included in the standard recommended intake.
However, the standard recommended intake amount does not take into consideration the intensity of the user's activity (hereinafter referred to as activity intensity). For this reason, there have been cases in which the recommended intake amounts for users who are exercising vigorously and for users who are exercising lightly are calculated to be the same.

Therefore, in the present embodiment, the reference intake amount calculation unit 12 corrects the reference reference intake amount with a correction value according to the user's situation. Specifically, the recommended intake amount calculation unit 12 calculates the activity intensity of the user based on the user's physical information and the competition information, and uses the calculated activity intensity as a correction value to calculate the reference intake guideline amount. Correct the amount.

The recommended amount of nutritional intake calculating unit 12 calculates the recommended amount of intake of each of energy and nutrients as the recommended amount of nutritional intake. In this case, the standard recommended intake amount is calculated for each of energy and nutrients, and each calculated recommended intake amount is corrected by a correction value based on the activity intensity of the user. In this case, the correction value for the recommended intake amount of energy and the correction value for the recommended intake amount of nutrients may be the same correction value or may be different correction values. Further, as the correction values for the recommended intake amounts of nutrients, the same correction value may be used for each nutrient, or different correction values may be used for each nutrient. Below, an example of a method for calculating the recommended amount of intake of energy by the calculation unit 12 of the recommended amount of nutritional intake will be described.

The recommended amount of nutritional intake calculation unit 12 calculates the recommended amount of energy intake out of the recommended amount of nutritional intake by the following (Equation 1).

Recommended energy intake = body weight x basal metabolic rate x activity intensity (Formula 1)

In the above (Equation 1), body weight is an element of physical information, and can be obtained from information stored in the item of body weight in the recommended nutritional intake database 30 shown in FIG. The basal metabolic rate is an element of physical information, and can be obtained from information stored in each item of sex and age in the recommended nutritional intake database 30 shown in FIG.

The recommended nutritional intake calculation unit 12 acquires the activity intensity based on the information of the sport classification, the division into periods, and the amount of exercise, which are elements of the sport information. For example, endurance and explosive competitions require greater activity intensity than technical and aesthetic competitions. Also, during the training period, the activity intensity is higher than during the game period and the off period. Also, when exercising five times or more a week, the activity intensity is higher than when exercising once a week.

The recommended nutritional intake calculation unit 12 calculates the activity intensity based on, for example, the relationship between the sport classification, the division into periods, and the amount of exercise. For example, the recommended amount of nutritional intake calculating unit 12 sets the value of the activity intensity to a value of 1.0 or more when increasing the standard activity intensity, and sets the activity intensity to 1.0 when not increasing the activity intensity. do. When the activity intensity is 1.0, the recommended amount of energy intake is the same as the reference amount of energy intake. When the activity intensity is set to a value of 1.0 or more, the recommended amount of energy intake for the user is determined so as to be larger than the standard recommended amount of energy intake, taking into consideration the activity intensity of the user. It is the amount after correcting the recommended intake amount.

The reference amount calculation unit 12 determines the activity intensity according to the relationship between the period division and the amount of exercise for each sport classification. For example, if a certain user X is classified as an endurance sport, exercises five times or more a week, and is divided into training periods, the range of activity intensity that can be set is determined by the calculation unit 12. set the highest activity intensity (for example, 3.0). Endurance sports consume more energy than other sports categories, and if the amount of exercise is 5 or more times a week, the level of physical activity is high and the basal metabolic rate is high, and even in the training period. This is because it is assumed that the activity intensity is higher and energy consumption is higher than in the off period.

On the other hand, even if the sport classification is endurance, if the amount of exercise is about once a week, even if the period division is the training period, the above-described user X is set. Set an activity intensity (for example, 1.0) that is smaller than the activity intensity set. Even in endurance sports, if you exercise once a week, your physical activity level will be low and your basal metabolic rate will be low. This is because

As described above, in the present invention, the recommended nutritional intake calculation unit 12 associates each of the sport classification, period division, and exercise amount with the activity intensity, so that the user's sport classification, period division, and exercise amount are associated with each other. It is possible to acquire an activity intensity suitable for the user from each information.
The sport classification can be obtained from the data stored in the sport classification item of the recommended nutritional intake database 30 shown in FIG. The periodization can be obtained from the data stored in the periodization item of the recommended nutritional intake database 30 shown in FIG. The amount of exercise can be obtained from the data stored in the item of amount of exercise in the recommended intake database 30 shown in FIG.

In the present invention, the reference intake amount calculation unit 12 may use the reference energy and the reference intake amount of each nutrient calculated as described above as the reference intake amount of each of the energy and nutrients. , the calculated reference energy and the recommended intake of each nutrient may be multiplied by a correction value based on the activity intensity to calculate the recommended intake of each of the energy and nutrients. It may be used as a reference intake amount, or it may be obtained by multiplying this reference value by a correction value. In this case, the recommended amount of nutritional intake calculating unit 12 may calculate a correction value for each sport classification stored in the item of the recommended amount of nutritional intake database 30 . Below, an example in which the recommended amount of nutritional intake calculating unit 12 calculates a correction value for each sport classification will be described.

For example, when the sport classification is an endurance sport, the recommended nutrient intake calculation unit 12 sets the correction value of the recommended nutrient intake so as to increase carbohydrates and minerals. In endurance competitions, there is a tendency for the duration and amount of exercise to be long, and the amount of sweat to be large, compared to other sports. Because there is

In addition, when the sport classification is a fast-paced sport, the recommended nutrient intake calculation unit 12 sets the correction value of the recommended nutrient intake so as to increase protein. This is because it is important to strengthen muscles and joints in explosive sports, and it is necessary to actively supply protein.

In addition, when the sport classification is an endurance or aesthetic sport, the recommended nutrient intake calculation unit 12 sets the correction value of the recommended nutrient intake so as to increase the iron content. This is because endurance competitions tend to consume iron, and aesthetic competitions tend to cause anemia due to excessive weight loss, so it is particularly necessary to replenish iron.

In addition, the recommended intake amount calculation unit 12 can set a correction value for the recommended intake amounts of nutrients using the period information. For example, when the period information includes information indicating an injury period or a rehabilitation period, the recommended nutritional intake calculation unit 12 reinforces proteins, minerals such as iron, vitamins, etc. intensively, and carbohydrates, etc. Set the correction value to reduce Note that the recommended intake amount calculation unit 12 may set the correction value of the recommended intake amount of nutrients using any of the competition information only, the period information only, or both the competition information and the period information. .

In the above description, the recommended intake amount calculation unit 12 calculates the reference recommended intake amount of energy, the reference recommended intake amount of nutrients, and the activity intensity based on the relational expressions for calculating each of them. Although illustrated and described, it is not limited to this. For example, the recommended intake amount calculation unit 12 may determine the recommended intake amount of energy, the recommended intake amount of nutrients, and the activity intensity based on a table (not shown) in which they are associated with each other. Specifically, the recommended intake amount calculation unit 12 uses a data table (not shown) in which the recommended amount of intake is associated with each combination of the user's weight and basal metabolic rate to calculate the reference energy intake. A guideline amount may be determined. In addition, the recommended intake amount calculation unit 12 uses a data table (not shown) that associates each nutrient with the recommended intake amount for each user's body weight and basal metabolic rate, and calculates the recommended intake amount for the reference nutrient. amount may be determined. In addition, the recommended nutritional intake calculation unit 12 may determine activity intensity using a data table (not shown) in which activity intensity is associated with each combination of sport classification, period division, and exercise amount.

FIG. 5 is an example of a display screen of the recommended amount of nutritional intake of the user terminal 20. As shown in FIG.
When receiving the recommended nutrient intake from the management server 10 through the communication unit 23, the user terminal 20 displays the received recommended nutrient intake via the display unit 25 as shown on the display screen 103 of FIG.
The display screen 103 displays, for example, the total energy intake as the recommended amount of energy intake, and the optimal recommended amount of intake for the user for each nutrient such as protein, lipid, carbohydrate, iron, and vitamins as the recommended amount of nutrient intake. is displayed numerically. Each user can maintain the optimum recommended intake of nutrients by watching the recommended intake of each nutrient displayed on the display screen 103 and eating.
