Development of digital based vertical jump test instruments

Abstract

The purpose of this research is to develop a digital Vertical Jump measuring instrument. This is because so far there are often errors in data collection related to the ability of leg muscle explosive power that is done conventionally. Resulting in a conclusion that is less valid. And therefore it is necessary to develop an instrument based on digital leg muscle power that is effective in its use and is economically efficient. This research is a development study with a design model adapted from Borg & Gall. Samples of Faculty of Sport Science (FIK) students of Padang State University, amounting to 10 people for small groups and 40 people for large groups, and 6 experts as validators as a validation tool. Data was collected using a questionnaire and trial tool. Through the validity of the product moment test and the reliability test, Test and Retest. The process of developing and testing this tool was carried out with the validation of experts by using a questionnaire as an instrument of validation and the results obtained an average percentage of 91%, the results of small group trials obtained a correlation level of 0.98 and the reliability test with direct trials of 0, 99 with the category of reliability is very strong.

Design of Power Sensor Based Test Instrument for Limb Muscle

“…Several previous studies have attempted to develop technology-based tests and measurements such as: touched on the effectiveness and efficiency of the product development of exercise programs general preparation physical based on Android [32], designed and evaluated a mobile application that could be used as an alternative in measuring the Physical Fitness [33], developed a volleyball skill test instrument [34] [35], produce development products for physical education sport and health learning media based on android applications [36]. The development of the vertical jump test instrument that has ever been of digital based vertical jump test instruments [37] and developed with camera kinect [38]. Determine the reliability of a simple and quick test to assess isometric posterior lower limb muscle force [39].…”

Profil Kondisi Fisik dan Keterampilan Psikologis Atlet Pencak Silat Perguruan Persinas ASAD Kota Bengkulu

“…Hasil dari penelitian ini menunjukkan bahwa kondisi fisik atlet pencak silat perguruan Persinas ASAD Kota Bengkulu secara keseluruhan masuk dalam kategori sedang dengan persentase 55,56%. Kondisi fisik dapat diukur dengan parameter tes dan pengukuran kondisi fisik yang terdiri dari 1) sprint 30 m untuk mengukur kecepatan, 2) shuttle run untuk mengukur kelincahan, 3) sit and reach untuk mengukur kelentukan 4) push ups dan sit ups untuk mengukur kekuatan otot lengan dan perut, dan 5) bleep test untuk mengukur daya tahan (Prabowo et al, 2020) Secara khusus, kondisi fisik atlet pencak silat perguruan Persinas ASAD Kota Bengkulu pada tes sit and reach dikategorikan sedang dengan persentase sebesar 44,44%. Dari lari 30 meter, tes ini bertujuan untuk mengetahui kecepatan atlet pencak silat yang dikategorikan sedang dengan persentase sebesar 44,44%.…”

Tarung Derajat Instrumentation Development

“…In addition, another factor that affects achievement is the utilization of existing technological advances [6,7]. Nurhasan stated that the obstacles in the coaching and training system that must be followed are not in accordance with the ideal coaching pattern and have not utilized technology optimally [8,9]. One of these weaknesses occurs in fighting degrees.…”
