Objectives
Narrative objectives1
In basketball, a wide range of physical fitness elements are required, such as vertical jump height (jumping ability), quickness in changing direction (agility), and speed of movement (sprinting). Furthermore, to improve players' performance during games, physical fitness testing is sometimes used to visualize each player's weaknesses, and training is conducted based on these results (Ohara et al., 2018, 2019, etc.). However, previous research has rarely investigated the relationship between physical fitness test results and abilities demonstrated during games. Consequently, many uncertainties remain regarding: 1. whether a relationship exists between physical fitness test results and abilities demonstrated during games, and 2. whether improvements in physical fitness lead to improved performance.
Therefore, to clarify the aforementioned points 1 and 2, this study conducts two investigations, Study 1: The Relationship Between Performance Quantified Using a Local Positioning System During Matches and Physical Fitness Test Values and Study 2: Does Improving Physical Fitness Values Enhance Performance During Matches?

Interventions/Control_1
Regular physical fitness assessments are conducted to quantify physical fitness values. Movements during practice and matches at the subjects' training facilities are quantified using a local positioning system. The relationship between these two sets of values is examined.To examine how fitness performance during competition changes, we will implement strength training: a commonly used method for improving physical fitness-over a 10-week period.
