Physical
factors play an important role in basketball free throw shooting success. This study
aims to analyze the factors associated with success when shooting from
different positions. Twenty-four college basketball players were assessed for
upper extremity length, muscle strength, vertical jump height and reaction
time, and hand reaction time. Five shooting positions (A–E) were located 4.54 m
from the basket at angles of 45° around a semicircle. Shooting
success was recorded as a percentage. The relationships between variables were
analyzed with Pearson correlation analysis, and multiple linear regression
analysis was performed to determine the contributions of the assessed physical
factors to shooting success. The following factors contributed to the success
rate: hand length, left palmar grip strength and left hand reaction time from
A; left palmar grip strength, left shoulder extensor strength and vertical jump
reaction time from B; left elbow extensor strength and left hand reaction time
from C; right wrist extensor strength, body mass index, left shoulder external
rotator strength, and left hand reaction time from D; and forearm length, left
elbow extensor strength, and left wrist extensor strength from E position. Left
elbow extensor strength, left hand reaction time, and vertical jump reaction
time contributed to the total free throw success rate. These results of this
pilot study demonstrated the important relationships between upper extremity
extensor strength, grip strength, vertical jump reaction time, hand reaction
time, and free throw success.
