###### Abstract
Moreover, this could be used to determine a set of biomechanical parameters and obtain the optimal movement structure for athletes [3]. Among the various types of throws, [PERSON] et al. [4] indicated that the ones most used in competitions are jump throws (73-75% of all throws during the game) and standing throws with a run-up (14-18%). Indeed, according to [PERSON] et al. [4], these two types of throws generate an increase in the horizontal velocity of the player while creating difficulty for the opponent. A biomechanical analysis of the kinematics of jump throws [5] could provide information on the ball's velocity, the maximal internal rotation of the trunk, and the trunk's flexion, as well as the angular velocity of the ball during shoulder rotation. The description and analysis of the upper limb's function in different types of throwing can be assisted by studies using the principles of biomechanics [6]. According to [PERSON] [7], for a throw to be more likely to succeed, the ball must achieve maximum velocity and accuracy. This is why, due to the greater ease of measurement, a large proportion of studies concerning the optimization of handball throws view the velocity of the ball as a performance parameter [8, 9, 10]. The type of throw has a direct influence on the velocity of the ball, as shown by several studies, such as [PERSON] [5], which highlighted the fact that the velocity of the ball on release is higher for an over-shoulder throw than for a hip throw. This explains why the latter form is less used in the game (constituting 38% of all throws, according to [PERSON] [7]). Because of their greater efficiency (measured by the ball's velocity at release) and more frequent use in play [4], it is interesting to focus on the differences and similarities in the biomechanical parameters of the standing throw and the jump throw. Numerous studies have already demonstrated the important correlation between the ball's velocity at release and the velocity of the internal rotation of the upper arm, such as [8, 11, 12]. [PERSON] et al. [8] suggested that working on the angular velocity of the internal rotation of the shoulder could improve the ball's velocity, and [11] confirmed this by revealing a significant relationship between the time taken to reach the maximum angular velocity of the shoulder and the elbow at the moment of the ball's release. This importance of timing was also supported by [13,14]. However, as pointed out by [15], the number of articles measuring and comparing the kinematic parameters between standing and jump throws is small compared to those studying a single type of throw. Additionally, these comparative studies, such as [9], have not focused exclusively on a kinematic study of the shoulder; rather, they consider the entire range of the upper limbs. Game performance is based on ball speed and coordination. This research hypothesis is based on the relationship between trunk rotation (torsion), exo/endorotation (external/internal rotation), and wrist velocity. This relationship could influence wrist velocity,depending on the type of throw. It is assumed that there are biomechanical differences between two types of throwing concerning the relationship between the angular velocity of the trunk torsion, the angular velocity of the arm rotation, and wrist velocity. The objectives of this research were to develop an algorithm for analyses of handball throwing based on two phases of throwing; to evaluate the role of trunk rotations in the throwing velocity; and to analyze the kinematic parameters of the upper limb angular velocity of the trunk rotation, the angular velocity of the arm rotation, and wrist velocity in two types of throwing: standing throws without a run-up and jump throws. We expected to find differences in timing (due to the presence or absence of ground support causing compensation in the arm's movements) and angular velocity.
