Abstract

The purpose of this research is to study and analyze the biomechanics that affect the lower serve technique. This research focuses on the body angle and position of the player's feet when serving down, and the purpose of this research is to gain a better understanding of the parts that affect the performance of the lower serve technique with a better level of precision.The type of research used by researchers is a quantitative method, using a descriptive quantitative approach. The instrument used is a handphone camera, can use a laptop equipped with the Kinovea 2023 version 1 application. 2 to record video. This application will serve to measure the angle of the body and legs when serving down in a volleyball game. object 1 produces a body angle of 112.8 °, as for the distance between the front and back legs 102.66 cm and a foot angle of 57.4 ° at the time of the ball's contact with the hand. object 2 data results produce a body angle of 93.1°, for the distance between the front and back feet produces a smaller distance compared to object 1 with a distance of 90.34 cm. the success of the lower serve that achieves effectiveness and also precision, is that objects with larger body angles and foot distances tend to successfully pass the ball across the net, while objects with smaller angles and foot distances experience failure.

Abstract

Football is one of the most popular sports in the world and requires good basic technique mastery to achieve optimal performance. This study aims to analyze the effect of body angle and foot position on the effectiveness of the inside foot passing technique in football, and this study does not only aim to understand the theory behind the passing technique. This research method is a type of quantitative descriptive research with a survey data collection technique on the inside foot passing test and measurement. The instruments used are a cellphone camera for video capture, a laptop containing the kinovea 2023 1.1 application/software object 1 body angle of 144.5° there is a balance of load distribution between the two feet, the distance between the feet is 78.11 cm. Meanwhile, the body angle is 168.3° The distance between the feet is 109.19 cm which is too wide also has an impact on the lack of dynamic stability. These results support the findings of previous studies which state that optimal body posture, appropriate body angle, and stable distance between the feet can significantly increase passing accuracy.
