Validity Test of Hamstring Muscle Strength Test for Handball Athletes

Abstract

The purpose of this study was to test the validity of hamstring muscle strength of handball athletes. A total of 30 handball athletes with categories of 15 male athletes (18.0 ± 5.1 years, weight 62.6 ± 20.7 kg, height 173.6 ± 5.0 cm, BMI 22.1 ± 4.0 kg / m2) and female (18.0 ± 5.1 years, weight 54.6 ± 17.4 kg, height 164.7 ± 6.9 cm, BMI 21.4 ± 2.2 kg/m2). No history of lower extremity injuries participated in a hamstring strength test. Hamstring strength tests are performed isometrically with ISO Prone and ISO 60 tests using nordbord tools and load cells tied using hooks called pabletest. From the test results there is a validity level of 0.000 with reliability of 0.8, so that the data can be said to be valid on both tests, namely ISO Prone and ISO 60. Load cells on pabletes are able to measure hamstring muscle strength in handball athletes. The advantages of load cells on pabletes can be made simply but not everyone can make arrangements so as to output data that can be interpreted. Subsequent research can be done using different contractions such as eccentrics and increasing the number of research subjects more by developing better software.

Do the physical elements improving archery performance?

“…The Superman back hold a test that can also be used as a back extension exercise that is effective in strengthening the lower back and toning the buttocks and hamstrings (Wiriawan et al, 2024). Exercising using both hands and feet, like Superman's back hold, can increase the needs of the body's muscles so as to improve sports performance (Hwang & Park, 2018).…”

“…Archery is a sport that is done by standing and aiming at the target (Wiriawan et al, 2024). Therefore archery requires coordination and stability so that the shot is right on target (Wiriawan et al, 2024). When the archer begins to maintain a bow-carrying posture, an imbalance begins (Park et al, 2016).…”
