Kinematic Factors Associated with Hitting Hurdles During the Initial Phase of a 110-m Hurdle Race.

This study aimed to clarify the kinematic factors for the cause and effect of hitting hurdles during the initial phase of a 110-m hurdle run. Nine experienced male hurdlers participated in this study (body height: 1.74 ± 0.04 m, body mass: 67.4 ± 5.9 kg, age: 20.2 ± 1.4 years, personal best: 15.21 ± 0.47 s, seasonal best: 15.33 ± 0.55 s). Hurdlers undertook 12 trials of the initial phase of hurdling from the start to the second hurdle landing. Dual-sided sagittal plane motion was obtained from images from two high-speed cameras operating at 120 Hz. One ‘hit’ trial which had the largest horizontal displacement of markers fixed on the hurdle and one ‘non-hit’ trial which had the fastest time of hurdle clearance were extracted for each participant. Kinematic variables were compared between the two trials. Significantly lower height of the whole-body centre of mass at the take-off was found as a possible cause of hitting hurdles, caused by insufficient swing-up of the lead leg thigh. In contrast to conventional understanding, take-off velocity, take-off distance and the take-off angle were comparable between the ‘hit’ trial and ‘non-hit’ trial. Regarding the effect of hitting hurdles, it was observed that running velocity during hurdling was not substantially reduced. However, several characteristic movements were identified that might induce inefficient motion to re-accelerate running velocity during the following landing steps.

Effect of body composition, anthropometric characteristics and lower body strength on the performance level of 110 m national hurdle athletes in Sri Lanka

Background: Many scholars have been identified that there is a relationship between body composition, anthropometric characteristics, lower body strength, and performance in several sports. In Sri Lanka, there is no proper mechanism to select 110m hurdle athletes based on body composition and anthropometric characteristics. Purpose: The main purpose of this study was to identify the relationship between body compositions, anthropometric characteristics, and lower body strength, and the performance of 110 meters hurdles national-level athletes in Sri Lanka. Methods: Using the census sampling method twenty-eight national-level male athletes were selected as the sample. Body composition measures are measured as height, weight, overall fat, visceral fat, subcutaneous fat, BMI, total muscle, trunk fat, trunk muscle, leg fat, leg muscle, arm fat, arm muscle. Leg length, feet length, trunk length, arm length, thigh circumference, and calf circumference were used to evaluate the anthropometric characteristic, and standing long jump was evaluated by the lower body strength. To analyze the data SPSS statistical software was used with descriptive statistics and paired samples t-test was used to determine the differences. Results: Positive correlations were found between performance and visceral fat, trunk fat, leg fat, arm fat. There was a negative correlation between performance and body height, total muscle, trunk muscle, leg muscle, arm muscle, feet length, trunk length, lower body strength. There were no significant correlations between performance and training age, weight, overall fat, subcutaneous fat, BMI, leg length, arm length, thigh circumference, and calf circumference (p > 0.05). Conclusion: Lower body strength, leg muscle, trunk muscle, and arm muscle and trunk length significantly influence the performance of national-level 110 meters athletes in Sri Lanka. Further, it can also be concluded that athletes who developed well in the leg, arm, and trunk muscles have a higher performance. And also athletes who have minimum fat in the arm, leg, and trunk reached the highest level of performance. Therefore, it can be concluded that players with higher lower body strength tend to stay in top performance

The Impact Of Short Run Distances To The Final Results Of The Decathlon At The 2019 Athletic World Championships

Athletic operates on the basis of a particular system of knowledge that has in its contentthe theoretical and methodological foundations of sport training (Rashiti N, Nika F, Bekolli L, Heta G.) 2017. Athletic is one of the types of sports, with complex and applicable character, consisting of large groups, which include different athletic types, with similar characteristics among them; our treatment is athletic decathlon.(Dibra F.)2006. The decathlon is a complexcombined event in athletic consisting of ten track and field events.Olympic men’s decathlons are divided into a two-day competition. The evaluation is done by points.Men’s decathlonconsists of:100m,Long jump,Shot put,High jump, 400m (Day 1); 110m hurdles,Discus throw,Pole vault,Javelin throw,1500m(Day 2).The main purpose of this paper was to verify that from the disciplines of the Decathlon:Long jump,Shot put,High jump, Discus throw,Pole vault,Javelin throw and1500m,as predictor (independent) variables will have an impact on the performance of specific motor tasks, respectively the execution of disciplines pertaining to short-distance running:100m, 110m hurdles and 400mas well as to determine the impact of these short-distance running to the final result of the decathlon knowing that these disciplines in athletics are largely genetically determined.(Misja B.) 2012The sample for the purposes of this paper will include 10 first contestants of decathlons World Championship: September 27 and October 6, 2019 in Doha, Qatar.In this research, after obtaining a statistically significant multiple correlation (R = 0.936) it is necessary to search for the coefficient in the (Beta) column as well as the (t-test) value indicating the influence of each predictor variable (independent) in the dependent or criterion variable 400m.We can emphasize that the test (F-test) is always more valuable if the multiplex correlation is greater, in this case it is significant (Sig = 0.000), because the value of the F-test is 15,347.A statistically significant multiple correlation was obtained (R = 0.958); it is necessary to search for the coefficient in the (Beta) column as well as the (t-test) value indicating the influence of each predictor (independent) variable in the dependent variable or criterion 110 m.In this research, after obtaining a statistically significant multiple correlation (R = 0.958), it is necessary to search for the coefficient in the (Beta) column as well as the (t-test) value indicating the influence of each predictor variable (independent) in the dependent or criterion variable) 100 m.

Performance Analysis of Men's 110-m Hurdles using Rhythmic Units

Objective: This study aimed to create a strategic training method to enhance optimal athletic ability using information from 1H to 10H rhythmic units. Method: Top three world class athletes and three national winners of 110-m hurdle finals from the 2010 Daegu International Athletics Competition and 2017 National Athletics Championship, respectively, were selected. To analyze the kinematic variables, Dartfish 9.0 was used for two-dimensional analysis. Results: Regarding the interval time from the start to the finish line, the national athletes took less time during the pure acceleration phase (start to 1H) than the foreign athletes. The horizontal velocity increase was slower after 1H; the national athletes showed a lack of ability to accelerate at the interval phases. Moreover, the hurdle clearance time between phases was longer in the national athletes than in the foreign athletes and lacked consistency. Conclusion: The national athletes lacked the ability to accelerate at the transition, maximum rhythm, rhythm maintenance, and re-acceleration phases and showed a longer hurdle clearance time. If technical improvements and strategic training methods using rhythmic units are applied for hurdling motions, the national athlete''s hurdling abilities, performance, and consistency could improve.

110m 허들 7보 주법 특성에 관한 연구: A pilot study

The objective of this study was to utilize a new technique to reduce an athlete’s personal record time through the application of the 7-step approach. This approach is often used by elite, world-class hurdlers in men’s 110-m hurdle events. We performed a kinematic analysis of the 7-step approach and the universally accepted 8-step approach on the present Korean record holder in hurdles (13.43 s). Upon analyses, we derived the following conclusions for the 7-step approach: 1) elongated start technique was used at the start; 2) higher stride length and rate in the 7-step approach than in the 8step approach; 3) extended trunk lean angle in the sprint phase and increased angular velocity at takeoff; 4) the point at which the maximum horizontal velocity of the center of mass was; 5) at takeoff, the distance between the foot and the hurdle was greater and the center of mass was closer in the 7-step approach than in the 8step approach; 6) at the peak of flight, the height of the center of mass, horizontal velocity, and size of the trunk lean angle of the upper body were greater in the 7-step approach than in the 8-step approach; and 7) at landing, the distance between the center of mass and the foot was lesser in the 7step approach than in the 8-step approach.

국가대표 육상 선수의 성장과정에 관한 내러티브 탐구 : 아시안게임 출전 과정을 중심으로

The The purpose of this study was to explore various educational meanings and values which national track-and-field athletes(110m Hurdle)acquired in their growth process and participation in Asian Games. For this purpose, this study conducted a narrative research, a type of qualitative research, on national athletes who participated in, and won medals in, the Asian Games. Domain analysis and classification analysis were conducted on the data collected through in-depth interviews and documents. In addition, veracity and ethicality of the study was obtained during the process of data collection and analysis. Results of analysis and interpretation of the collected data in this study are as follows. First, although there were many stories and conflicts in the stage in which athletes began their lives as athletes, they could achieve their goals when they kept working hard based on strong willpower. Second, in their growth process, athletes faced motives to grow themselves and the confidence obtained in such experiences worked as an important factor in their athletic performances. Third, it was necessary for them to experience training system of advanced countries to enhance their performance and the trust between the coaches and athletes was an important factor in the process of athletes’ growth. Fourth, athletes’ physical and mental state in important games became the very key to victory while psychological pressure caused by the lack of experience led to defeats in the games.Although defeats may bring enormous pain to the athletes and disappointment toward the athletes themselves, they worked as a motive and opportunity for the athletes to grow into more mature athletes. Fifth, loving their work was a true happiness. Professional consciousness as athletes and self-confidence functioned as a great motivation for them to live as athletes.

Effects Of Altitude On Performance Of Elite Track-and-field Athletes

Lower density and oxygen content of air at higher altitudes affects competitive performance of athletes in some sports, which has resulted in track-and-field performances at venues above 1000 m classified as “altitude” performances. PURPOSE: Here we quantify the effects of altitude on track-and-field athletes to determine whether such designation is appropriate. METHODS: Lifetime track-and-field performances of athletes placed in the top 16 in at least one major international competition between 2000 and 2009 were downloaded from the database at tilastopaja.org. There were 132,104 performances of 1889 athletes at 794 venues. Performances were log-transformed and analyzed using a mixed linear model with fixed effects for 6 levels of altitude and random quadratic effects to adjust for athlete’s age. RESULTS: Men’s and women’s sprint events (100-400 m) showed marginal improvements of ∼0.2% at altitudes of 500-999 m, and above 1500 m all but the 100-and 110-m hurdles showed substantial improvements of 0.3-0.7%. Some middle- and long-distance events (800-10,000 m) showed marginal impairments at altitudes above 150 m, but above 1000 m the impairments increased dramatically to ∼2-4% for events >800 m. There was no consistent trend in the effects of altitude on field events up to 1000 m; above 1000 m hammer throw showed a marginal improvement of ∼1%, discus was impaired by 1-2%, and women’s high jump was impaired by ∼1.5%. Above 1500 m, pole vault, triple jump and long jump showed marginal improvements of ∼1%. CONCLUSIONS: The findings in sprinting and some field events generally support the 1000-m threshold for altitude designation, but there is no need for such designation for middle- and long-distance running, high jump, shot-put, discus and javelin.

Skeletal muscle signature of a champion sprint runner.

We had the unique opportunity to study the skeletal muscle characteristics, at the single fiber level, of a world champion sprint runner who is the current indoor world record holder in the 60-m hurdles (7.30 s) and former world record holder in 110-m hurdles (12.91 s). Muscle biopsies were obtained from the vastus lateralis at rest and 4 h after a high-intensity exercise challenge (4 × 7 repetitions of resistance exercise). Single muscle fiber analyses were conducted for fiber type distribution (myosin heavy chain, MHC), fiber size, contractile function (strength, speed, and power) and mRNA expression (before and after the exercise bout). The world-class sprinter's leg muscle had a high abundance (24%) of the pure MHC IIx muscle fibers with a total fast-twitch fiber population of 71%. Power output of the MHC IIx fibers (35.1 ± 1.4 W/l) was 2-fold higher than MHC IIa fibers (17.1 ± 0.5 W/l) and 14-fold greater than MHC I fibers (2.5 ± 0.1 W/l). Additionally, the MHC IIx fibers were highly responsive to intense exercise at the transcriptional level for genes involved with muscle growth and remodeling (Fn14 and myostatin). To our knowledge, the abundance of pure MHC IIx muscle fibers is the highest observed in an elite sprinter. Further, the power output of the MHC IIa and MHC IIx muscle fibers was greater than any human values reported to date. These data provide a myocellular basis for the high level of sprinting success achieved by this individual.

Effects of altitude on performance of elite track-and-field athletes.

Lower barometric air pressure at altitude can affect competitive performance of athletes in some sports. Reported here are the effects of various altitudes on elite track-and-field athletes' performance. Lifetime track-and-field performances of athletes placed in the top 16 in at least 1 major international competition between 2000 and 2009 were downloaded from the database at tilastopaja.org. There were 132,104 performances of 1889 athletes at 794 venues. Performances were log-transformed and analyzed using a mixed linear model with fixed effects for 6 levels of altitude and random quadratic effects to adjust for athlete age. Men's and women's sprint events (100-400 m) showed marginal improvements of ~0.2% at altitudes of 500-999 m, and above 1500 m all but the 100- and 110-m hurdles showed substantial improvements of 0.3-0.7%. Some middle- and long-distance events (800-10,000 m) showed marginal impairments at altitudes above 150 m, but above 1000 m the impairments increased dramatically to ~2-4% for events >800 m. There was no consistent trend in the effects of altitude on field events up to 1000 m; above 1000 m, hammer throw showed a marginal improvement of ~1% and discus was impaired by 1-2%. Above 1500 m, triple jump and long jump showed marginal improvements of ~1%. In middle-and long-distance runners, altitudes as low as 150 to 299 m can impair performance. Higher altitudes (≥1000 m) are generally required before decreases in discus performance or enhancements in sprinting, triple and long jump, or hammer throw are seen.

110 m 허들경기의 제 1허들에 대한 우수선수와 비우수선수의 운동역학적 요인 비교

The purpose of this study was to provide a fundamental information for enhancing 110m hurdlers' perfor- mance through conducting comparative biomechanical analysis between Skilled Group(SG) and Less- Skilled Group(LSG) those who are not in the first section of 110m hurdles. To persue the purpose of this study, total of 10 hurdlers participated. Then they were divided into two groups; SG: five hurdlers who have won awards with 14-second range at 2010 national track and field event, and LSG: five hudlers who did not win any awards with 15-second range. Three-dimensional motion analysis with 12 infrared cameras(Oqus 300, Qualisys) and 1 force plate(Type 9286AA, Kistler) was performed. From this study following conclu- sions were obtained. 1) For the overall runtime, SG revealed faster elapsed time than that of LSG. 2) At E4, LSG showed greater trunk angle than that of SG. 3) At E3 LSG revealed higher angular velocities than that of SG. 4) No significant differences was found for AP GRF between groups but LSG showed greater VGRF than that of SG.

Start reaction time and performance at the sprint events in World Athletic Championships

The aim of this study was to determine the relationship between the start reaction time and the performance in men sprinters who participated at the World Indoor Athletics Championships. This study’s sample was 161 athletes (n=161) who participated in the final races of 100m (n=52), 200m (n=55) and 110m hurdles (n=54) in Athens 1997, Seville 1999, Edmonton 2001, Paris 2003, Helsinki 2005, Osaka 2007 and Berlin 2009 IAAF World Athletics Championships. The evaluation of start reaction time as well as the sprinters’ performance was based on the official published reports of International Association of Athletics Federations (IAAF). The MANOVA showed that significant differences between athletes’ start reaction time were identified only in 110m hurdles sprint event [F(6.43)=4.70], p<0.001. The post hoc comparisons reported that the start reaction time (125ms) in the 110m hurdles final in Athens 1997 was the best recorded in all sprint final races during the evaluated Championships from 1997 and on. Because the start reaction times in all final sprint races were recorded better in Athens 1997 than after the Paris 2003 Championships leads to the conclusion that the new IAAF false start rule has a negative effect in top-level athletes’ start reaction time.

2011 대구세계육상선수권대회 110m 허들 선수의 허들링 기술 동작의 운동학적 분석

The purpose of this study was to evaluate the kinematic characteristics of and hurdle clearances during the final of the 110-m hurdles at the IAAF World Championships, Daegu 2011. To this end, the hurdling motions of the top 4 ranked male hurdlers in the competition were analyzed. A total of 12 cameras were used to record their motions, with a sampling frequency of 120 Hz. The cameras were calibrated using control objects that covered all of the lanes (1st~8th lanes). After analyzing all the data, we arrived at the following results. In the take-off phase, all athletes revealed similar take-off times (CT), and similar distances from the take-off to hurdleto (L1) and hurdle to landing (L2). In particular, Turner, ranked , had an inconsistent L2 and may need further training to correct it. In the flight phase, Richardson, ranked , showed the longest flight distance, whereas Xiang, who was ranked , showed the highest CG height from the hurdle. For the step patterns, to increase the pitch frequency, Richardson and Xiang used shorter 3-step lengths than Turner and Oliver.
