With the development of technology, new services in the field of forensics are also being developed. In practice, there is a great need for objective human comparison between different video recordings. For this reason, we have developed a new forensic kinematic motion comparison service. This is based on a relative 2D kinematic analysis of the per...

The purpose of this report is to provide additional analysis and commentary on the men’s 100 m world record of 9.58 s, set by Usain Bolt in the 2009 Berlin World Championships in Athletics. In addition, the entire race underwent a unique kinematic analysis, particularly emphasizing the maximum running velocity and its related factors. It was possib...

The objectives of this study were to investigate the reliability, validity, and usefulness of the 30–15 intermittent fitness test (30–15 IFT ) in soldiers. The 34 infantry members of the Slovenian armed forces were recruited as participants. Participants performed the continuous incremental treadmill test (TR), a 2-mile run (2 MR ) test, and two 30...

The industrial development of technology, with appropriate adaptation, enables us to discover possibilities in sport training control. Therefore, we have developed a new approach to linear running analysis. This study aims to determine the measurement possibilities using an LDM301A laser system in obtaining basic kinematic parameters. The second go...

Findings of the studies on the relationship between isometric handgrip contraction and changes in cerebral blood flow (CBF) are contradictory. The aim of the study was to evaluate CBF changes during one minute of a maximal handgrip isometric contraction. Our main hypothesis was that the maximal handgrip test will cause a decrease in CBF related to...

The purpose of the study was to compare the biomechanical parameters of the hurdle clearance technique of the fifth hurdle in the 110 m hurdle race of Colin Jackson of Great Britain (12.91 s world record was set in 1994) and Dayron Robles of Cuba (12.87 s world record was set in 2008), two world record holders. Despite the athletes having performed...

Purpose: The purpose of research was to determine important kinematic variables, which determine result in shot put of international level athlete. Athlete used rotational technique of shot put, which is very demanding from movement coordination point of view. Methods: With MVN Xsens dress with 17 accelerometers (data acquisition 120 Hz) we measure...

This study investigated the maximal sprint velocity kinematics of the fastest 100 m sprinter, Usain Bolt. Two high-speed video cameras recorded kinematics from 60 to 90 m during the men 100 m final at the IAAF World Challenge Zagreb 2011, Croatia. Despite a relatively slow reaction time (194 ms), Bolt won in 9.85 s (mean velocity: 10.15 m/s). His f...

Development and recognition of new gymnastics element is subjected to the evaluation of difficulty and structural complexity of the skill. The authority over the procedure lies with the Technical Committee of International Gymnastics Federation (FIG TC) and thus the classification of an element is a result of the subjective perception of its member...

V študiji smo analizirali tehniko sprinta najhitrejšega tekača na tem planetu, dvakratnega svetovnega rekorderja in dvakratnega olimpijskegazmagovalca v teku na 100 m U. Bolta. Na osnovi 2-D kinematične analize, ki smo ju izvedli na mednarodnem tekmi IAAF World Chalange - Zagreb 2011, Hrvaška, smo proučevali biomehaniko sprinterskega koraka v pogoj...

Usain Bolt is one of the greatest athletes in the history of the ''queen of sports''. He has won six golden Olympic medals and is the world record holder in the 100-metre sprint (9.58 sec), 200-metre sprint (19.19 sec) and 4x100-metre relay (36.84 sec). The ''fastest man alive'', the ''man from another galaxy'', the ''Lightning Bolt'' are but a few...

The study aimed to establish the modalities of the rotational shot put technique of two elite shot putters with substantially different constitutional characteristics. A biomechanical analysis of the technique was carried out using the APAS 3-D kinematic system, whereby a 15-segment model of shot putters was defined by 18 reference points. To enabl...

The aim of our research was to study the relationships between performance variables in a support backward swing (SBS), which was used as a progressive step in the learning procedure for a 1 1/4 straddle-piked front somersault and the swing prior to a 1 1/4 straddle-piked front somersault from support to bent arm support on the parallel bars (5/4S)...

The aim of our research was to study the relationships between performance variables in a support backward swing (SBS), which was used as a progressive step in the learning procedure for a 1#fr1/4> straddle‐piked front somersault and the swing prior to a 1#fr1/4> straddle‐piked front somersault from support to bent arm support on the parallel bars...

The study aimed at identifying the kinematic and dynamic variables of the sprinting stride which most affect maximal sprinting velocity of the centre of gravity (CG) on a 5 m distance. The study was conducted on 7 female elite sprinters subjected twice to a laboratory 5 m run with a flying start (40 m approach). A tensometric platform installed in...
