Type Of Injury

Background: Athletes participating in track and field jumping events (long jump, triple jump, high jump, and pole vault) are exposed to ground-reaction forces on the takeoff leg that are several times their body weight. This can cause injuries specific to such activities. Purpose: To determine the incidence of injuries in collegiate jumpers using the guidelines set forth by a 2014 consensus statement on injury surveillance during track and field events. Study Design: Descriptive epidemiology study. Methods: A total of 51 jumpers between April 2016 and March 2017 and 54 jumpers between April 2017 and March 2018 participated in this study. All athletes were from a single college in Japan. Baseline information on athletes participating in the long jump, triple jump, high jump, and pole vault was collected at study enrollment. Practice and competition exposures were reported by the team trainer. Injury incidence was calculated as the number of injuries per 1000 athlete-exposures (AEs). Results: A total of 147 injuries were reported among 16,998 exposures (8.65 injuries per 1000 AEs). The most common injury locations were the posterior thigh and lateral ankle (17.0%), followed by the posterior foot or toe (12.9%); the most frequent type of injury was strain/muscle rupture/tear (21.1%). The most common injury for long jumpers was ankle sprain (23.3%); for high jumpers, flexor hallucis longus tendinosis (15.8%); and for pole vaulters, hamstring strain (13.2%). Conclusion: The overall characteristics are different for each event; therefore, injuries for each event need to be investigated.

Purpose: To describe and identify individual trends and changes in training load, neuromuscular readiness, and perceptual fatigue measures in 2 youth elite long jumpers, finalists at the European Athletics U18 (Under 18) Championships (athlete A, female, age 16.5 y, long-jump record 6.25 m; athlete B, male, age 16.0 y, long-jump record 7.28 m). Methods: Data were collected from both training sessions and athletics competitions during a 16-week period, divided into a preparation (weeks 1–8) and a competitive phase (weeks 9–16). Training load was computed through training diaries (training time, sprint, jumping, and weights volume). The countermovement jump and the 10-to-5 repeated-jump test were executed on a weekly basis to assess neuromuscular readiness, and perceptual fatigue measures were collected through a wellness questionnaire. Statistical analysis was conducted using a magnitude-based decisions approach. Results: The results highlighted a decrease in training load during the competitive period with moderate to large differences for training time, sprint, and jump volume. Moreover, data showed an upward trend and very likely higher scores in vertical-jump performance across the competitive phase together with a very likely lower perceptual fatigue. Conclusions: This scenario seemed to be favorable to achieve competition performance very close to the personal record during the competitive season. This study provided an example of application of a comprehensive monitoring system with young athletes involved in track-and-field jumping events.

Abstract Introduction. The aim of this study was to examine the changes in selected kinematics in the long jump, triple jump, and pole vault to highlight the unique movement pattern characteristics in the approach runs utilised in these events. Material and methods. Data were collected during 1 international and 2 national competitions from 36 male athletes (12 in each event) using an Optojump Next system. Results. This study showed the long jumpers achieved the highest mean step velocity, with the pole vaulters showing the lowest velocity. The velocity of the last step before the take-off was greater (p < 0.05) than the velocity of the penultimate step in all groups of athletes. The length of the last step before the take-off was greater (p < 0.01) than the length of the penultimate step in long jump and pole vault athletes compared to the triple jumpers. The long jumpers demonstrated less contact time (p < 0.01) than the pole vaulters. The contact time of the take-off leg was shorter (p < 0.01) compared to that of the non-take-off leg in pole vaulters. The pole vaulters demonstrated less flight time (p < 0.05) compared to the triple jumpers. Lastly, the flight time during the last step before the take-off was shorter (p < 0.01) than the flight time during the penultimate step in all groups. Conclusions. These findings revealed that each of the track and field jumping events required a distinctive approach run. Therefore, training workouts need to be designed specifically to train the unique gait pattern of the long jump, triple jump, and pole vault.

Purpose:To examine the acute effects of a conditioning plyometric exercise on long-jump performance during a simulated long-jump competition.Methods:Eight national-level track and field decathletes performed 6 long-jump attempts with a full approach run separated by 10-min recoveries. In the experimental condition subjects performed 3 rebound vertical jumps with maximal effort 3 min before the last 5 attempts, while the 1st attempt served as baseline. In the control condition the participants performed 6 long jumps without executing the conditioning exercise.Results:Compared with baseline, long-jump performance progressively increased only in the experimental condition, from 3.0%, or 17.5 cm, in the 3rd attempt (P = .046, d = 0.56), to 4.8%, or 28.2 cm, in the 6th attempt (P = .0001, d = 0.84). The improvement in long-jump performance was due to a gradual increase in vertical takeoff velocity from the 3rd (by 8.7%, P = .0001, d = 1.82) to the 6th jump (by 17.7%, P = .0001, d = 4.38). Horizontal-approach velocity, takeoff duration, and horizontal velocity at takeoff were similar at all long-jump attempts in both conditions (P = .80, P = .36, and P = .15, respectively).Conclusions:Long-jump performance progressively improved during a simulated competition when a plyometric conditioning exercise was executed 3 min before each attempt. This improvement was due to a progressive increase in vertical velocity of takeoff, while there was no effect on the horizontal velocity.

And Task

By analysis of footfall variability in the long jump, triple jump, and pole vault, the present study was designed to highlight gait variability patterns required in varied nested tasks. Twelve male athletes in each event who participated in one international and two national competitions were involved in this study. Twenty five pairs of 1-m Optojump Next system bars were used to evaluate relevant footfall placement. The footfall variability was taken to present the pattern of step regulation and onset of visual regulation. The main results of this study showed that pole vaulters manifested a highly consistent gait pattern, which was different than the pattern which appeared in the horizontal jumps. The results also revealed that the onset of step length adjustments in the horizontal jumps occurred significantly later during the zeroing-in phase of the approach run in comparison to those utilized by the pole vaulters. These findings indicate that locomotor pointing control in the long jump, triple jump, and pole vault produce specific footfall variability patterns due to different task and environmental constraints that need to be taken into account during training and competition settings.

Summary The authors have evaluated the combined track-and-field events performed by the female students of the Faculty of Physical Education and Sport of Comenius University in Bratislava (CU FPES) in the years 2013 – 2017. The combined track-and-field events are an obligatory part of the final Athletics examination in the teacher-training study program. The selected disciplines reflect the first day of the men’s decathlon with the exception of the last one, which is replaced by 800 m. The number of points in the combined event enters into the overall assessment of the subject Didactics of Athletics II together with an oral examination. The authors analysed not only the total number of points in the pentathlon but also in the individual disciplines and their percentage share in the final result. They have discovered that the shot put and high jump are among the most stable disciplines. The greatest variance of the percentage share in the overall number of points was observed in the 100 m dash, 800 m and in the long jump. The performance of a high number of students (almost two-thirds) came below the average performance in the particular year as expressed in points.

While physical performance decline rates accelerate after around the age of 70 years, longitudinal athletic performance trends in athletes older than 95 years are unknown. We hypothesized a further accelerated decline in human performance in athletes who still perform at the age of 100 years. To investigate this, longitudinal data of all athletes with results at or over the age of 100 years were collected from the “World Master Rankings” data base spanning 2006–2019 (138 results from 42 athletes; 5 women, 37 men; maximum 105 years) and compared to previously published longitudinal data from 80- to 96-year-old athletes from Sweden (1,134 results from 374 athletes). Regression statistics were used to compare performance decline rates between disciplines and age groups. On average, the individual decline rate of the centenarian group was 2.53 times as steep (100 m: 8.22x; long jump: 0.82x; shot put: 1.61x; discus throw: 1.04x; javelin throw: 0.98x) as that seen in non-centenarians. The steepest increase in decline was found in the 100-m sprint (t-test: p &lt; 0.05, no sign. difference in the other disciplines). The pooled regression statistics of the centenarians are: 100 m: R = 0.57, p = 0.004; long jump: R = 0.90, p &lt; 0.001; shot put: R = 0.65, p &lt; 0.001; discus throw: R = 0.73, p &lt; 0.001; javelin throw: R = 0.68, p &lt; 0.001. This first longitudinal dataset of performance decline rates of athletes who still compete at 100 years and older in five athletics disciplines shows that there is no performance plateau after the age of 90, but rather a further acceleration of the performance decline.

Background and Study Aim. Athletic jumps are specific cyclically-acyclic movements that despite the good performance of the techniques require from competitors a high level of motor, specific-motor and functional abilities. The aim of this study was to examine the response effect of vertical and horizontal plyometric training on explosive capacity and kinetic variables in long jump athletes. Material and Methods. The participants of this study were twenty professional jumpers (22.5 ± 4.2 years; 178.4 ± 9.8 cm; 70.3 ± 7.6 kg) who were divided into two groups: experimental (plyometric training) and control (standard training). They participated in the last track and field championship in country, moreover, three of them participated in the last Asian games, and one athlete participated in the world track and field championship. The experiments were conducted on June-July 2019 in twenty professional athletes. All tests were performed after a standard warm up protocol. The place of camera was always determined wisely around the jumping field to attain best photography. Organizing and controlling the imaging and motor analysis processes were done by a biomechanics expert. Results. Post training results in experimental group showed more improvement in 30 m sprint, vertical jump, horizontal velocity at take-off, and long jump completion, comparing the control group. Significant between group differences in all variables were detected post training. No significant post training improvements in flight time and take off duration were reported in control group. Conclusion. Vertical and horizontal plyometric training protocol was shown to be more effective in promoting improvement in explosive capacity than kinetic variables.
