Abstract
Description
Technical Field
[0001] The present invention relates to sports competitions, and in particular to a method for evaluating an athlete's combat effectiveness index. Background Art
[0002] Many sports are played in a competitive format, where athletes are assigned to two teams and compete against each other. Examples include racket sports (table tennis, tennis, badminton, etc.), martial arts (judo, karate, boxing, wrestling, etc.), and strength sports (tug-of-war, arm wrestling).
[0003] Taking badminton as an example, singles and doubles are the primary formats for competition. Whether in singles or doubles, it's crucial that the two teams are equally matched. This impacts fairness, the quality of the game, and the overall experience. However, categorizing similarity in badminton matches is difficult with the current format. Generally, skill or level is largely determined by subjective perception, and overestimation or underestimation of skill often creates a potential for unfairness. Summary of the Invention
[0004] The main purpose of the present invention is to provide a method for evaluating an athlete's combat power index, which provides a method for evaluating the combat power of athletes for reference by event organizers, so that players of similar strength can be assigned to the same group to compete, thereby improving the fairness and fun of the competition.
[0005] To achieve the aforementioned objectives, the present invention provides a method for evaluating an athlete's combat effectiveness index, which evaluates the combat effectiveness indexes of multiple athletes through competition, and includes the following steps:
[0006] Step 1: Obtain the initial combat power index of multiple athletes;
[0007] Step 2: sorting the multiple athletes according to their initial combat effectiveness indexes, and assigning the multiple athletes to at least one evaluation group in that order;
[0008] Step 3: Arrange the athletes in each evaluation group to compete against each other and record the competition data of each athlete; the competition data includes: number of games, number of wins, number of losses, total points and total points lost; and
[0009] Step 4: After the game is over, the combat power indexes of the multiple athletes are calculated based on their initial combat power indexes and the game data.
[0010] In one embodiment, the initial combat power index refers to the combat power index of the athlete previously obtained according to the evaluation method.
[0011] In one embodiment, if the athlete has never obtained a combat power index before, the initial combat power index is obtained in any of the following ways: 1. A senior athlete who has participated in the evaluation method of the present invention and is familiar with the athlete's strength provides the athlete's initial combat power index; 2. The athlete finds an athlete with similar strength in the records of all athletes who have participated in the evaluation method of the present invention, and uses the athlete's combat power index as the athlete's initial combat power index; and 3. Questionnaire survey.
[0012] In one embodiment, in step three, a dedicated person is assigned to record the game data of the players participating in the game on the sidelines.
[0013] In one embodiment, in step three, the game is recorded by video, and then the game data of the players participating in the game are obtained through image recognition technology.
[0014] In one embodiment, the variables used to calculate the combat power index include a point-scoring combat power index and a win-loss combat power index. The point-scoring combat power index is obtained by applying a predetermined formula to the initial combat power index, the number of games played, the total points scored, the total points conceded, and the difference in the initial combat power index with the opponent. The win-loss combat power index is obtained by applying a predetermined formula to the initial combat power index, the number of wins, the number of losses, and the number of games played.
[0015] In one embodiment, the final combat power index can be obtained by inputting the initial combat power indexes of the plurality of athletes and the plurality of game data into a computer, and then calculating the final combat power index using a computer program in the computer.
[0016] The athlete combat power index evaluation method provided by the present invention can obtain the athlete's combat power index after each game and use it as a basis for grouping in subsequent games, allowing players of similar strength to compete with each other, thereby improving the fairness and fun of the game. BRIEF DESCRIPTION OF THE DRAWINGS
[0017] (none) DETAILED DESCRIPTION
[0018] A preferred embodiment of the present invention provides a method for evaluating an athlete's combat effectiveness index, comprising the following steps:
[0019] Step 1: Get the initial combat power index of multiple players:
[0020] The so-called "initial combat power index" refers to the combat power index obtained by players who have participated in the evaluation before the present evaluation method is used. Of course, some players have never participated in the evaluation method of the present invention. Such players can obtain their initial combat power index by the following method:
[0021] 1. An experienced player who has participated in the evaluation method of the present invention and is familiar with the player's strength provides the player's initial combat power index.
[0022] Second, the player finds a player with similar strength to himself from the records of all players who have participated in the evaluation method of the present invention, and uses the player's combat power index as the player's initial combat power index.
[0023] 3. Obtain the player's initial combat power index through a questionnaire survey.
[0024] If the player does not know any senior players and cannot find players of similar strength in historical records, the only way to obtain the player's initial combat power index is through a questionnaire survey. The following table shows the content of the questionnaire:
[0025] □I am a male player □I am a female player □ Regularly plays tennis for 0 to less than 2 years, and can play simple and easy games in a team □ Regularly plays for 2 to less than 5 years, and can play games of medium or higher intensity in a team □ Regularly played for 3 years / moderate intensity, with multiple international competition experiences □Elementary school lower grade players □Elementary and middle school players □ Senior elementary school players □ Junior high school badminton class □High school badminton class □General university / vocational college team □Professional Badminton Group B □Professional badminton group A / coach
[0026] Based on the above questionnaire and statistics from past Combat Power Index competitions, the reference ranges for the Combat Power Index of players at different levels are as follows:
[0027]
[0028]
[0029] Step 2: sort all players according to their initial combat power indexes, and assign the players to a plurality of evaluation groups in order so that the initial combat power indexes of the players in each evaluation group are close.
[0030] The next step is for the players in each evaluation group to compete against each other. Although the evaluation method of the present invention can evaluate a player's performance index after just one match, it is still desirable to balance effective evaluation with interesting and diverse competitions. The number of evaluation groups, the number of players in each group, and the competition format are determined based on the total number of players participating in the evaluation. For example, when evaluating in singles mode, the number of players in each group is preferably 4-6; when evaluating in doubles mode, the number of players in each group is preferably 6-8.
[0031] Step 3: Players in each evaluation group compete against each other, and the game data of each player is recorded.
[0032] During each match, players' game data is recorded. This includes the number of games played, wins, losses, total points scored, and total points conceded. Recording can be done by a designated person or referee on the sidelines, or by video recording using image recognition technology to capture game data from both players.
[0033] Step 4: Calculate the player's new combat power index based on the player's initial combat power index and game data.
[0034] After the game is over, the combat power index of the players on both sides can be calculated. The calculation formula is as follows:
[0035] Single-game points scored / conceded power index (PI_PTi) = OPI × (1 + (1 / N) × (PW - (PL + DPI)) / PL)
[0036] in:
[0037] OPI: The initial power index of the opposing player
[0038] N: Number of games
[0039] PW: Total score
[0040] PL: Total points lost
[0041] DPI: The difference in initial combat power index with the opponent
[0042] Total points scored and lost (PI_PTS) = (PI_PT1 + PI_PT2 + ... + PI_PTN) / N
[0043] in:
[0044] PI_PTN: Single-game scoring and losing power index obtained in the match against player N
[0045] N: Number of games
[0046] Total win-loss power index = OPI × (1 + 0.3 * (WIN-LOST) / N)
[0047] in:
[0048] OPI: The initial power index of the opposing player
[0049] WIN: Number of wins
[0050] LOST: Number of losses
[0051] N: Number of games
[0052] Then, based on the total points scored and lost combat power index and the total win-loss combat power index, the player's single-game combat power index can be calculated. The formula for the single-game combat power index is as follows:
[0053] Single-game Combat Power Index (PI) = (Total Points Gained and Lost Combat Power Index + Total Wins and Losses Combat Power Index) / 2
[0054] Finally, after obtaining the player's single-game combat power index obtained in this evaluation process, the average of the indices calculated based on the previous participation in different competitions is calculated. The previous and the new indices of this evaluation are the final combat power index. The formula for the final combat power index is as follows:
[0055] Final combat power index (API) = (PI_1 + PI_2 + ... + PI_N) / TN
[0056] in:
[0057] PI_N: Single-game power index obtained by playing against player N
[0058] TN: Total number of matches
[0059] The following example illustrates the process of the athlete combat power index evaluation method of the present invention:
[0060] Twelve players participated in the athlete performance index assessment of the present invention. They were ranked according to their initial performance index and divided into three assessment groups, each consisting of four players with similar initial performance indexes. The initial performance index (OPI) and grouping of these 12 players are shown in the following table:
[0061]
[0062] Next, let's take the evaluation of the combat power index of player B1 in evaluation group B as an example:
[0063] Players B1, B2, B3, and B4 in evaluation group B played singles matches in pairs, playing three matches against each player. A dedicated person was assigned to record match data courtside. The following table shows the match data collected for each player in each match:
[0064]
[0065] Then, the single-game point-gained combat power index of player B1 can be calculated from the game data obtained after the game to obtain the total point-gained combat power index of player B1.
[0066]
[0067] Finally, based on the above calculation results, the total points gained and lost combat power index is obtained and the total win-loss combat power index is calculated to obtain the final combat power index of player B1 in this evaluation.
[0068] Total points scored and lost 4.686 Total win-loss power index 4.928 Final combat power index 4.807
[0069] Based on the aforementioned data and the same calculation process, the final combat power index of players B2, B3, and B4 can be calculated as follows:
[0070] players B2 B3 B4 Final combat power index 5.372 3.725 4.126
[0071] The aforementioned calculation of each strength index can be performed by a computer program. A person only needs to input the required game data, and the computer program can automatically calculate the strength index of each player.
[0072] Through the evaluation method described above, the final combat power index of each player can be obtained after each game to understand the strength of each player. In the next game, the players can be grouped according to the final combat power index obtained in the previous game (which becomes the initial combat power index of this game) to ensure that the strength of the players in the group is comparable. This can improve the fairness of the game and make the game more interesting.
[0073] Finally, it should be noted that while this embodiment uses badminton as an example to illustrate how to evaluate an athlete's final combat effectiveness index, other similar sports, such as tennis and billiards, that require two teams of athletes to compete against each other can also utilize the evaluation method provided by this invention.
[0074] The above embodiments are merely illustrative of the techniques and effects of the present invention and are not intended to limit the present invention. Any person skilled in the art may modify or alter the above embodiments without violating the technical principles and spirit of the present invention. Therefore, the scope of protection of the present invention shall be as described in the following patent claims.
