“…It can be argued that professional athletes exhibit smoother and more controlled wrist motion during an FT shot. It has been well established that highly skilled athletes show differing kinematics to those of a lower skill, and this study expands upon these differing kinematics [7][8][9]. Whilst the inclusivity of G Y only increases the accuracy by 1% (88%) (compared to 87% if only consider A Z and A X ), it increases the sensitivity by 1% and specificity by 3%.…”

In terms of FT movement, higher skilled players exhibited a smaller center of gravity excursion and different joint kinematics at the wrist joint, when compared to those of lower skill [7][8][9]. Specifically, well-trained basketball players demonstrated a greater degree of wrist motion (173 ± 5.1 • ) when compared to less skilled players (156 ± 10.2 • ).…”

Wearable sensors are an emerging technology, with growing evidence supporting their application in sport performance enhancement. This study utilized data collected from a tri-axial inertial sensor on the wrist of ten recreational and eight professional basketball players while they performed free-throws, to classify their skill levels. We employed a fully connected convolutional neural network (CNN) for the classification task, using 64% of the data for training, 16% for validation, and the remaining 20% for testing the model’s performance. In the case of considering a single parameter from the inertial sensor, the most accurate individual components were upward acceleration (AX), with an accuracy of 82% (sensitivity = 0.79; specificity = 0.84), forward acceleration (AZ), with an accuracy of 80% (sensitivity = 0.78; specificity = 0.83), and wrist angular velocity in the sagittal plane (GY), with an accuracy of 77% (sensitivity = 0.73; specificity = 0.79). The highest accuracy of the classification was achieved when these CNN inputs utilized a stack-up matrix of these three axes, resulting in an accuracy of 88% (sensitivity = 0.87, specificity = 0.90). Applying the CNN to data from a single wearable sensor successfully classified basketball players as recreational or professional with an accuracy of up to 88%. This study represents a step towards the development of a biofeedback device to improve free-throw shooting technique.

“…Free throws were made according to the game rules. Participants were told to throw the ball into the basket within 5 seconds after the ball was thrown using Phases of free-throw A-Preparation phase: It is the process in which visual information is received before starting the action; B-Acceleration: It is the process in which the shooting movement begins, phased as its beginning and end; C-Shooting: the moment of the shooting and the process of handing the ball; D-Flight: It is the process that starts with the last wrist movement after the ball is released and ends with the release [35].…”

Background and Study Aim. This study investigates expert and amateur basketball players' visual tracking strategies accuracy and inaccuracy free throws. Material and Methods. A total of 22 university student, 11 of whom were experts (n = 5 females, n = 6 males) and 11 amateurs (n = 5 females, n = 6 males), without visual impairment, participated the study. Each athlete performed a total of 10 throws. The normal distribution of data recorded in both accurate and inaccurate throws was checked with the Shapiro-Wilk test. All of the data received on accurate and inaccurate throws were analyzed by independent samples t-test. Results. Expert basketball players were recorded to have an average of 78% accurate throws out of 10, and as for amateur basketball players, they were recorded to have 34%. During accurate throws, the quiet eye durations of expert basketball players were identified as ~886ms, and quiet eye durations during inaccurate throws were as ~570ms. During accurate throws, the quiet eye durations of amateur basketball players were identified as ~612ms, and quiet eye durations during inaccurate throws were as ~388ms. The study's findings reveal that expert basketball players develop statistically longer quiet eye and fixation durations than amateur basketball players. Conclusion. The study's findings have supported the phenomenon of longer quiet eye durations during expert athletes' specific motor skills. The knowledge obtained from the study's findings is thought to have the utmost significance in identifying the quiet eye durations of expert basketball players and teaching their visual strategies to amateur level athletes to improve their performance.

“…This is when the importance of speed of information processing or reasoning ability may have a vital role. Although researchers studied various facets of basketball (6)(7)(8)(9)(10)(11), so far no such study has been conducted in order to study shooting skills of basketball players in the light of their reasoning ability, hence the present study is an attempt to assess shooting skills of female basketball players on the basis of their level of reasoning ability they possess. It was hypothesized that shooting skills of female basketball players would be significantly influenced by their reasoning ability.…”

In the present study, field goal shooting skills of female basketball players were assessed in the background to their reasoning ability. The sample consists of 100 female intercollegiate basketball players (age = 21.05±1.67 yrs.). Shooting skills and reasoning ability were assessed by Johnson's "Basketball Field Goal Speed Shooting Test" and Mixed Type Group Test of Intelligence prepared by Mehrotra (1984), respectively. Results reveal that field goal shooting ability of female basketball players exhibiting superior reasoning ability was found to be significantly better as compared to field goal shooting ability of female basketball players with low and average reasoning ability. It was concluded that shooting skills of female basketball players is influenced by their cognitive ability i.e. ability to rationalize problems in proper sequence.
