As shown in Figures 1, 4, 6, and 10, in a first embodiment of the present invention, a multifunctional fitness testing device 1 includes a main body 10, a muscle endurance test piece 20, a flexibility test piece 40, a grip test piece 50, a cardiopulmonary function test piece 60, a muscle strength test piece 70, a long jump test piece 80, a weight and body fat measurement piece 90, a height measurement piece 100, a host 200, a wireless sensor 110, and a finger pulse clip 120. The wireless sensor 110 of the present invention is a detachable armband that can capture the user's physical information (such as heart rate or body temperature) and is designed for the user to wear on the arm to monitor the user's physical condition during exercise. The finger pulse clip 120 is designed in the form of a glove so that the user can wear it on the palm of the hand. It can detect the user's pulse through infrared rays and also monitor the user's blood oxygen and blood pressure.

The host 200 of the present invention is used to record the user's fitness data or identity data when using the multifunctional fitness testing device 1 and transmit the data to a cloud server 300. The host 200 includes a display interface 201, an input interface 202, an identity sensing interface 203, a controller 204, a wireless module 205, and a network module 206. The controller 204 is electrically connected to the display interface 201, the input interface 202, the identity sensing interface 203, the wireless module 205, and the network module 206. The controller 204 is, for example, a CPU processor, which controls the operation of the internal components of the host 200. The host 200 can be installed with an operating system (such as Windows, iOS, Android, or Linux) and domestic fitness norms. The system of the host 200 can automatically interpret and test the user's athletic performance. The system automatically compares the individual's test data with the norms, automatically interprets the test scores, and assesses various fitness strengths and weaknesses. The host 200 is rotatably connected to the main body 10 . The user can adjust the display angle of the host 10 so as to view the display interface 201 of the host 10 from multiple angles.

The display interface 201 is used to display data for the user to view, play prompts to remind the user of the operating process of the multifunctional fitness monitoring device 1, and provide user instructions or navigation information to help the user understand the functions of the multifunctional fitness monitoring device 1. The input interface 202 is used to allow the user to enter fitness data such as height, weight, waist circumference, hip circumference, blood pressure, blood sugar, glycated hemoglobin, cholesterol, and uric acid levels, as well as personal information such as identification code, ID number, name, gender, unit, birthday, email address, and mailing address. However, the data that can be entered is not limited to these. In addition, the method of entering data is not limited to the input interface 202. For example, the host 200 may have a mobile phone number database and mobile phone call input software, allowing the user to use a mobile phone to dial a special number to communicate with the host 200 and enter data using the numeric keys on the mobile phone.

The identity sensing interface 203 is, for example, an RFID card, RF card, or RF-SIM card reader/writer module for user identification. Thus, the user can use iCash, Taipei Citizen Health Card, various MRT cards (EasyCard, One Card, etc.), student ID cards, mobile phones, and other devices with sensing functions, so that the identity sensing interface 203 senses the device held by the user for identity identification. However, the identity identification mechanism of the present invention is not limited to the identity sensing interface 203. The user can also enter the data corresponding to the identity (such as an ID card, mobile phone number, email, code, etc.) through the input interface 202 for identity identification. Through the identity identification mechanism of the identity sensing interface 203, different usage permissions can be planned for different identities to manage the data recorded by the host 200 of the present invention.

Wireless module 205 is used to wirelessly and electrically connect to the muscular endurance tester 20, the flexibility tester 40, the grip tester 50, the cardiopulmonary function tester 60, the muscle strength tester 70, the long jump tester 80, the weight and body fat measurement device 90, the height measurement device 100, and a wireless sensor 110. This allows a user to transmit exercise data to host 200 via wireless module 205 while exercising with these components. The wireless connection method of wireless module 205 of the present invention is radio frequency (RF), but the present invention is not limited to this wireless connection method.

Network module 206 is used to communicate with cloud server 300 to transmit physical fitness data, identity data, or exercise data to server 300. This allows server 300 to host app systems, such as a healthy diet-related app system, a night market-related app system, a sports-related app system, a leisure and tourism-related app system, and a health and medical assessment and exercise prescription app system. These apps can integrate physical fitness data, identity data, or exercise data with various app systems, allowing users to closely monitor their diet, physical fitness, and lifestyle through the app systems and server 300, thereby properly managing their health. The server 300 can also compile and manage each user's fitness data, identity data, or exercise data (e.g., analyzing and ranking fitness test data by year, age group, region, and individual fitness test). The server 300 then notifies the user, designated friends and family, a designated medical team, or a designated health advisory team of the results via text message or email, allowing for relevant diagnosis and health care. This allows the user to understand their own fitness level (e.g., comparing their fitness level to the average fitness level of athletes of the same age group, comparing before and after exercise, comparing before and after medical treatment, comparing diet control, comparing specific types of fitness levels, etc.). After receiving the results from the server 300, the user can choose to print the data or share the results on social networking sites (e.g., Facebook, Twitter) to share their fitness achievements or health index with fellow athletes, family, or specific groups.

The host 200 also has a storage device and a database to store and manage the aforementioned fitness data, identification data, or motion data generated by the user operating the multifunctional fitness detection device 1. However, storing data in a storage device is not the focus of the present invention, and this feature has been disclosed in the relevant field of computer data storage devices, so the present invention will not further elaborate on it.

As shown in Figures 2 and 10, in the first embodiment of the present invention, the muscle endurance test piece 20 is connected to the main body 10. The muscle endurance test piece 20 includes a folding plate 21 and a foot fixing piece 22. The foot fixing piece 22 is connected to the folding plate 21. The folding plate 21 can be used for the user to sit or lie down, and can be folded according to the user's body angle. The surface of the folding plate 21 is made of waterproof material to prevent the user's sweat from adhering, and the folding plate 21 can be easily cleaned with clean water. The foot fixing piece 22 is used to temporarily fix the user's angle so that the user can exercise. For example, the user can lie on the folding plate 21 with his feet fixed on the foot fixing piece 22, and the folding plate 21 is bent to an angle that matches the user's legs, so that the user can do sit-ups. The foldable board 21 of the present invention can be equipped with a pressure sensor to sense changes in pressure during sit-ups, thereby collecting information about the sit-up (e.g., exercise rate, exercise time, and weight). The foldable board 21 transmits this information to the wireless module 205, allowing the host 200 to manage the user's sit-up information and display the data for the user to view. However, the sensing mechanism and application of the muscle endurance tester 20 are not limited to the above. The foldable board 21 can also be equipped with an infrared sensor to analyze the sit-up data by measuring the change in height of the user from lying down to sitting up. The user can also use the pressure sensor of the muscle endurance tester 20 or the infrared sensor to measure their height and weight.

As shown in Figures 3 and 10, in a first embodiment of the present invention, a flexibility tester 40 is positioned adjacent to the foot support 22 to measure the user's body flexibility. The flexibility tester 40 may be equipped with a sensing push plate, and the distance the user pushes the sensing push plate is used to calculate the user's body flexibility. However, the design of a sensing push plate is common knowledge in the field of flexibility testing, so this invention will not elaborate on its design. In actual use, the flexibility tester 40 of the present invention can be used by a user sitting on the flattened muscle endurance tester 20, securing their foot to the foot support 22, and then touching the flexibility tester 40 with their hand. The flexibility tester 40 calculates the user's body flexibility by sensing the distance the user's hand pushes the sensing push plate. The flexibility information is then transmitted to the wireless module 205, allowing the host 200 to manage the user's body flexibility information and display the motion data for the user to view.

As shown in Figures 4 and 10 , in the first embodiment of the present invention, the grip strength tester 50 is an ergonomically designed hand grip ring used to measure a user's grip strength. The grip strength tester 50 transmits grip strength information to the wireless module 205 , allowing the host 200 to manage the user's grip strength information and display the data for the user to view. The grip strength tester 50 can be configured to measure one to three grip strength tests, with the host 200 calculating the average grip strength or capturing the best result as the final grip strength data.

As shown in Figures 5 and 10, among the first embodiment of the present invention, the long jump test piece 80 is a flat plate, which can be provided with a distance scale, so that the user can estimate his long jump distance after the long jump. The long jump test piece 80 can also be provided with a pressure sensor, and after the user has long jumped, by estimating the different pressure positions, measure the user's long jump distance. The long jump test piece 80 can transmit the motion information of the long jump to the wireless module 205, so that the main frame 200 can manage the motion information of the long jump of the user and display motion data for the user to watch. When the user does not need to use the long jump test piece 80, the user can store the long jump test piece 80 in the space under the main body 10 to save the space occupied by the multifunctional physical fitness detection device 1.

As shown in Figures 6, 7, and 10, in the first embodiment of the present invention, the weight and body fat measuring device 90 is a platform with weight sensing, body fat calculation, and audio functions, and the height measuring device 100 is a stand for measuring height. Users can measure their weight and body fat on the weight and body fat measuring device 90 and their height using the height measuring device 100. The weight and body fat measuring device 90 and the height measuring device 100 can transmit the user's height, weight, and body fat data to the wireless module 205, allowing the host 200 to manage the user's height, weight, and body fat data and compile BMI and BMR values, or analyze weight, body fat, body water content, muscle mass, muscle gain and loss, body mineral content, and changes in arm, waist, hip, or leg circumference for display to the user. The user can also perform step-up exercises while wearing the wireless sensor 110 on the weight and body fat measurement device 90. The weight and body fat measurement device 90's audio function can play music or a fixed rhythm, allowing the user to synchronize their step-up exercises with the sounds played by the weight and body fat measurement device 90. The wireless sensor 110 can sense the user's heartbeat and transmit this information to the host 200. The weight and body fat measurement device 90 can also detect the user's step-up speed and frequency, and transmit this information to the host 200 for integration and display to the user. However, the mechanism for measuring height and weight is not limited to the above-mentioned weight and body fat measuring device 90 and height measuring device 100. For example, the height measurement function of the height measuring device 100 can be combined with a muscle endurance testing device 20 with an infrared sensing function; and the weight measurement function of the weight and body fat measuring device 90 can be combined with a muscle endurance testing device 20 with a pressure sensing device; thereby, the muscle endurance testing device 20 can combine the weight measurement function of the weight and body fat measuring device 90 and the height measurement function of the height measuring device 100.

As shown in Figures 8 to 10, in the first embodiment of the present invention, the muscle strength testing piece 70 is connected to the cardiopulmonary function testing piece 60. The muscle strength testing piece 70 is used to test the user's arm muscle strength. When the muscle strength testing piece 70 is actually used, the user can first adjust the weight of the muscle strength testing piece 70, then sit on the muscle endurance testing piece 20, hold and pull the muscle strength testing piece 70 with his hands, so that the muscle strength testing piece 70 tests the user's muscle strength or muscle endurance and other muscle strength values. The muscle strength testing piece 70 can transmit the user's muscle strength data to the wireless module 205, so that the host 200 can manage the user's muscle strength data and display it to the user for viewing. The muscle strength testing piece 70 can be set to measure 1 to 3 muscle strength tests, and the host 200 calculates the average muscle strength or captures the best results as the final muscle strength data. The cardiopulmonary function test piece 60 is used to test the cardiopulmonary function of the user. It is designed to be in the form of a bicycle pedal. When the cardiopulmonary function test piece 60 is actually used, the user can sit on the muscle endurance test piece 20 and step on the pedal of the cardiopulmonary function test piece 60. The cardiopulmonary function test piece 60 will record the user's cardiopulmonary function exercise information such as the pedaling speed, calories consumed, and distance moved by pedaling, and transmit the user's cardiopulmonary function exercise information to the wireless module 205 so that the host 200 can manage the user's cardiopulmonary function exercise information and display it to the user.
