The ability of eye-hand coordination is needed in table tennis performance. Therefore, measuring the eye-hand coordination of table tennis performance is necessary. This study aimed to develop a measuring instrument for table tennis eye coordination and test its validity and reliability. This study uses mixed methods-data collection using the Delphi technique and test-retest. The participants were three academic experts, four table tennis professional experts, and fourteen table tennis athletes. This research instrument uses a questionnaire with a rating scale of one to four, namely very relevant, relevant, less relevant, and irrelevant. It uses a measuring instrument for hand-eye coordination. Data analysis used Aiken's formula, Intraclass Correlation Coefficients (ICC), and Cronbach Alpha. The results of this study that measuring eye-hand coordination of table tennis performance show the first aspect: the suitability of the coordination concept has a value of V = 0.952, the second aspect: the suitability of the number of stimuli has a value of V = 0.857, the third aspect: the suitability of distance has a value of V = 0.952, the fourth aspect: the suitability of the movement has a value of V = 0.857, the fifth aspect: the suitability of the test procedure has a value of V = 0.857. The Intraclass Correlation Coefficients (ICC) test has a value of 0.875. The reliability test has a value of 0.891. Based on these results, the eye-hand coordination measuring instrument has content validity and high reliability. Therefore, the eye-hand coordination measuring instrument can be used to measure table tennis performance.

“…Based on the literature review from several international journals using thematic analysis, the resulting concept of sensor-based reactive agility was found to be the speedy direction change in short side steps or sprints after receiving an unplanned stimulus (Inglis & Bird, 2016;Matlák et al, 2017;Nugroho et al, 2022;Spiteri et al, 2015). Additionally, the concept and blueprint for the construction of a sensor-based reactive agility measurement tool for net game sports groups were obtained, as shown in Figure 1 below: The test subject prepares to start in the purple box, facing the four lights.…”

“…Research on competitive performance in net game sports has demonstrated its links to the characteristics of fast short movements, acceleration, and quick changes in direction (Qowiyyuridho, Tomoliyus, & Fauzi, 2021). Attempting to define reactive agility some practitioners insinuated that it refers to rapid whole-body movement with a change in speed and direction after responding to a stimulus (Nugroho, Tomoliyus, Alim, Fauzi, & Yuliarto, 2022). Reactive agility incorporates a cognitive component by involving perception and reaction to cues indicating the direction of a turn (Spiteri, Newton, & Nimphius, 2015).…”

It is challenging to develop a measurement of Reactive Agility because the latter is one of the physical components that is highly influenced by internal and external factors. It is thus difficult to perform related measurements due to uncertainties in open game conditions, specifically in the net game group. The purpose of this research is to validate the content of a sensor-based Reactive Agility measurement tool in net game group sports. In terms of the research method, the researchers used a mixed-method approach, combining qualitative and quantitative methods. The research subjects consisted of seven academic and professional experts in the net game group sports. While the data collection technique used is the Delphi technique, related data were collected using a four-scale rating, whereby scale 1 indicated “not suitable”, scale 2 “indicated less suitable”; scales 3 and 4 “indicated “suitable”, and “highly suitable” respectively. For this validation, the data analysis was conducted using Aiken's formula. Which all aspects have high content validation because the V value is higher than Aiken's standard value (0.76). The respective values for each aspect include; conceptual definition V = 0.952, measuring tool construction V = 0.952, sensors show a value of V = 0.905, test procedures V = 0.905, and scoring V = 0.952.

This study aims to determine the effect of BOTELI interval training on the groundstroke forehand rally skills of tennis. This research was conducted on the tennis court of the Faculty of Sports Science, Sebelas Maret University, Surakarta. The research method uses experiments. The sample in this study was 24 students of the Faculty of Sports Science, Sebelas Maret University, Surakarta, for the 2021/2022 academic year. The training method in this study uses BOTELI exercises with 1:1 and 1:3 intervals. The measuring instrument is the kemp-vincent rally tennis skill test. The data analysis technique was Paired T-Test at a significance level of = 0.05 using SPSS version 20 software. The results showed that BOTELI interval training could improve forehand groundstroke rally skills in tennis. However, there are differences between the 1:1 interval BOTELI training method with the 1:3 interval BOTELI training method in enhancing the groundstroke rally forehand skills of tennis. For students with a BOTELI interval of 1: 1, the results are better than 1:3 with an average value (1:1 = 63.58 and 1:3 = 48.42). In this study, it was found that the advantages of BOTELI interval training with a dose of 300 strokes per training session and every 20 strokes there is an interval lag, so after making several 1800 strokes, students can play tennis simply. The benefits of using BOTELI tools in doing groundstroke forehand rally techniques are efficiency and function. Efficient in terms of cost, time and number of balls used, its function will result in mastery of the forehand groundstroke rally technique quickly because, in terms of similarities, the training using BOTELI is very similar to the general groundstroke forehand rally exercise, even more, flexible and adaptive. The use of BOTELI aids also functions for implementing exercise programs such as exercise frequency and training intervals will be more easily fulfilled or achieved. This BOTELI tool can be useful for doing groundstroke forehand rally exercises easily, cheaply, and comfortably and can be done independently.
