The relationship between anthropometric and physical characteristics of female handball players and throwing velocity is considered an important factor in handball performance. The aim of this study ...was to examine key differences in anthropometric and fitness characteristics between top elite and elite female players competing in the first Spanish handball league. A total of 89 players from the first Spanish handball league were divided into two groups, top elite (38) and elite (51) players, and assessed for anthropometric and fitness characteristics (throwing velocity, vertical jump and hand grip strength). A Student’s t-test was used to determine whether a statistically significant difference between the two different levels of play occurred. Significant differences were found in age, body height, body mass, arm span, muscle mass, different girths (tensed and flexed arm, forearm, wrist, ankle), dominant hand width and length, different breadths (biacromial, bitrochanteric, bistyloid breadth and biepicondylar humerus) and fitness characteristics (hand grip strength and throwing velocity for different positions). Top elite players compared to elite players showed differences in anthropometric characteristics which were mainly located in the upper limbs and mostly were nonmodifiable aspects by training. Furthermore, the best players were able to maintain a high throwing velocity in different tactical situations.
Abstract Objective To explore the application of fuzzy mathematics calculation in quantitative evaluation of students’ basketball jump shot performance. Methods Using the basic theory of fuzzy ...mathematics and the calculation method of fuzzy correlation, the correlation degree between the training means and the free throw hit rate was obtained, and further, the best training means to improve the free throw hit rate of basketball players were selected. As a result, when the ball reaches the highest point or falls after reaching the highest point, it is pushed out towards the 45° Angle, making the basketball fly to the basket in an arc. The jump shot is designed to avoid being blocked by a defender and is very effective against players of similar size or when no one is guarding. Conclusion The method proposed in this paper is suitable for the evaluation of college basketball teaching and ball skill training, and provides theoretical basis and quantitative data for training.
The purpose of the present study was to examine differences in kinematic characteristics between (a) proficient and non-proficient two-point and three-point shooters, (b) made and missed two-point ...and three-point shots within a proficient group of shooters, and (c) shots attempted from two-point and three-point shooting distances. Eighteen recreationally active females with previous basketball playing experience attempted 10 two-point (5.10 m) and 10 three-point shots (6.32 m) while facing directly to the basket. To eliminate the possible influence of fatigue, each shot was separated by a 5–10 s rest interval. Participants who made ≥50% of their two-point and ≥40% of their three-point shooting attempts were classified as proficient. A high-definition video camera recording at 30 fps and video analysis software (Kinovea) were used to obtain the kinematic variables of interest during both the preparatory phase (PP) and release phase (RP) of the shooting motion. The results indicate that proficient two-point shooters attained less hip and shoulder flexion during the PP and had greater release height and vertical displacement during the RP. Hip angle differentiated made from missed two-point shots within the proficient group of shooters, with made shots being depicted by less hip flexion. Significantly greater vertical displacement was observed in proficient three-point shooters during the RP. Additionally, the greater elbow and release angles separated made from missed three-point shots within the proficient group of shooters. In response to an increase in shooting distance, hip, knee, ankle, and shoulder angles during the PP all decreased. Moreover, an increase in shooting distance caused a decrease in release angle and an increase in vertical displacement during the RP, while the relative release height remained unchanged.
Basketball players usually score points during the game using the jump shot. For this reason, the jump shot is considered to be the most important element of technique in basketball and requires a ...high level of performance. The aim of this study was to compare the biomechanical characteristics of the lower limbs during a jump shot without the ball and a countermovement jump without an arm swing. The differences between variables provide information about the potential that an athlete can utilise during a game when performing a jump shot. The study was conducted among 20 second-league basketball players by means of a Kistler force plate and the BTS SMART system for motion analysis. The variables measured included the take-off time, mean power, peak power, relative mean power, jump height, maximum landing force and calculated impact ratio. Surprisingly, more advantageous variables were found for the jump shot. This finding suggests a very high performance level in the jump shot in the studied group and a maximum utilisation of their motor abilities. Both types of jumps were characterised by high mean and peak power values and average heights. The high forces at landing, which result in considerable impact ratios, may have prompted the studied group to land softly. Use of the countermovement jump without an arm swing is recommended to assess and predict the progression of player’s jumping ability
Background: This study was designed in two poles, 1st to examine the kinematic parameters of the handball jump shot and 2nd to compare the anthropometric, and physical fitness of novice and skilled ...female handball players of the university level. Methods: This study design was cross-sectional, and a purposive sampling method was adopted for selecting the participants. The sample consisted of (n = 20) novice, and (n = 20) university female handball players. The selected variables were standing broad jump, vertical jump, flexibility, 30-m dash, agility, stride length, stature, body mass, arm length, upper arm girth, leg length, chest girth, waist girth, hip girth, thigh girth, calf girth, hand length, handbreadth and shoulder breadth, pelvic breadth, transverse breadth, elbow and knee breadth, handgrip and arm span, left and right knee angle, left and right elbow angle. An Independent t-test was applied to examine differences between skilled and novice players in kinematics and anthropometric variables. Results: Results showed the skilled female players were significantly higher than the novice players in the following as right elbow angle at the start of movement (<. 03), left elbow angle at the start of movement (<. 00), right knee angle at the start of movements (< .03), stride length at release (< .01), 30-meter dash (< .04), handgrip strength(< .02), agility (< .03), forearm girth (< .03), thigh girth (< . 03) and arm span (< .04). Conclusion: It was concluded the higher angle of elbows, right knee along with more prolonged stride increase the movement capacity of skilled female handball player while attempting the jump shots than novice female players. On the other hand, the anthropometric and fitness measures as arm span, thigh girth, running speed, handgrip strength, and agility increase the performance of skilled players than the novice. The female handball coaches may enhance the performance of novice players by focusing on the specific training of extension and flexion of elbows and stride movement as well as enhancing the physical fitness of female handball players. Future studies would focus on the training of handball players to increase the jump shot performance of players.
The research aims at preparing dynamic tactical exercises for young basketball players identifying the effect of dynamic lactic exercises in some physiological variables and accuracy of jump shooting ...for young basketball players. The researchers use the experimental method though experimental design of equivalent groups pre and post measurements as it is appropriate to the nature of the research. The research community is determined by 15 basketball players from the Imam Al-Muttaqin Sport Club for the 2015-2016 season. The researchers use a comprehensive limited method when selecting the research sample. physiological variables were studied (pulse rate, blood lactic acid concentration, maximum oxygen consumption Vo2 Max). Some of the most important findings the researchers came up with was that dynamic lactate exercises had an effect in improving the heart rate before and after the fatigue as well as the level of lactic acid before and after fatigue and Vo2 Max level.
