Description

Technical Field

[0001] The present invention relates to the technical field of sports fatigue detection, in particular to a sports fatigue detection device, and also includes a sports fatigue detection method. Background Art

[0002] In military physical training, sports training or outdoor sports, reasonable muscle fatigue is beneficial to improve the fatigue resistance of the trainees' muscles, but excessive sports fatigue may cause permanent muscle damage and irreversible harm to the trainees. Therefore, it is necessary to detect the sports fatigue state in time during competition or training. At present, the monitoring of fatigue mainly adopts the heart rate method or the subjective feeling of the person himself, and there is a lack of fast, real-time and effective fatigue detection devices and methods. Summary of the invention

[0003] The present invention aims to provide a detection device and method for sports fatigue, so as to solve the problem in the prior art that excessive sports fatigue causes permanent damage to muscles.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A sports fatigue detection device includes a device body and a data processing center, wherein the device body is rotatably connected to a first detection rod and a positioning rod, the first detection rod is connected to a connecting rod and a first detection member, the connecting rod is provided with a sliding groove, the sliding groove is slidably connected to a second detection rod, the lower side of the second detection rod is connected to a second detection member, and the first detection member and the second detection member are both electrically connected to the data processing center.

[0006] Furthermore, the second detection rod is connected to the connecting rod by a thread, the lower side of the second detection rod is connected to a detection spring, the detection spring is electrically connected to the data processing center, the free end of the detection spring is connected to an insulating plate, and the insulating plate is connected to the second detection member.

[0007] Furthermore, the device body is also connected to a scale plate, which is used to measure the angle between the first detection rod and the positioning rod, and the connecting rod is engraved with scale marks, which are used to measure the position of the second detection rod.

[0008] A method for detecting sports fatigue, using a sports fatigue detection device to detect sports fatigue, comprises the following steps:

[0009] S1: Set the comparison group sample, detect the signal value between two points when the trainee's muscle part is completely quiet, and calculate the difference in the signal value between the two points;

[0010] S2: Obtain the test group samples. After the trainee stops the competitive training, he / she immediately measures the signal value between the two points corresponding to S1, and calculates the difference in the signal value between the two points.

[0011] S3: Data analysis: comparing and analyzing the data difference between the test group and the control group, and judging the fatigue degree of the trainees according to the data difference.

[0012] Furthermore, in S1 and S2, the measured muscle parts include: ankle muscles, meniscus muscles, biceps brachii of the upper arm, deltoid muscle of the upper arm, brachioradialis muscle of the forearm, extensor digitorum of the forearm, extensor carpi radialis longus of the forearm, extensor carpi radialis brevis of the forearm, quadriceps femoris of the lower limb, and tibialis anterior muscle of the lower limb.

[0013] Furthermore, in S1 and S2, the distance between two points in the muscle area is measured as a random integer numerical distance between 0 mm and 48 mm.

[0014] Furthermore, in S1 and S2, the signals detected between the two points include chemical signals, physical signals, electrical signals and muscle elasticity. The chemical signals include the detection of the components of the trainee's sweat. The detection method is to integrate the reduced graphene oxide film into the porous microstructure of three-dimensional inverse opal cellulose acetate to construct a highly sensitive multifunctional sensor, adsorb the sweat through the siphon effect, and perform sweat detection. The color and reflective spectrum changes of the inverse opal cellulose acetate can be used to achieve simultaneous online monitoring of the NaCl in the sweat during these exercises; the physical signals include the trainee's stimulation perception, and the detection method uses skin space valve detection; the electrical signals include electromyographic signals, and the detection method is needle electrode signal detection; the muscle elasticity includes the contraction distance of the skin after the skin is compressed, and the detection method is to convert the deformation of the detection spring.

[0015] Further in S3, the method for judging the fatigue degree of the trainee is as follows: when the concentration of NaCl in sweat is greater than 90mM, it is judged that the human body is in a state of dehydration, the training intensity is high, and the body is in a state of fatigue. If the threshold value of the skin space valve detection after pausing competitive training is more than 1.5 times higher than that when it is quiet, it is mild fatigue; if the threshold value after pausing competitive training is more than 2.0 times higher than that when it is quiet, it is severe fatigue. The muscle hardness increases, the contraction function decreases, and it cannot fully relax, which is judged as a fatigue state.

[0016] The principle and beneficial effects of this technical solution are:

[0017] The positioning rod is used as the detection reference of the entire detection device. The position of the first detection member and the second detection member can be adjusted by sliding the second detection rod to adjust the distance between the two measuring points, which is easy to operate and use.

[0018] 1. By rotating and adjusting the angle between the first detection rod and the positioning rod, the distance between the positioning rod and the part to be detected can be adjusted. It is applicable to a wide range of parts and is beneficial to improving the detection accuracy;

[0019] 2. The second detection element is connected to the detection spring through an insulating plate, which can simultaneously complete the detection of electrochemical signals and muscle elasticity of the muscle part, and the detection efficiency is high;

[0020] 3. The signals between two points include chemical signals, physical signals, electrical signals and muscle elasticity. The detected data is comprehensive and the detection accuracy is high;

[0021] 4. Needle electrode electromyographic signal detection has little interference and is easy to identify; sweat NaCl concentration accurately reflects body changes; muscle hardness truly reflects athletic ability; space valve detection method is easy to operate;

[0022] 5. Adjust the intensity or method of the tester's competitive training in time according to the tester's sports fatigue status to avoid permanent damage to the tester's muscles due to excessive sports fatigue. BRIEF DESCRIPTION OF THE DRAWINGS
