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.

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.

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.

The field events in the sport of track and field athletics include a wide range of very different disciplines. They can be divided into the jumping events (long jump, triple jump, high jump, and pole vault) and the throwing events (javelin, shot putt, hammer, and discus). In modern track and field athletics, all disciplines are performed by both sexes. Injuries relate to the training methods and the specific technical features of each event....

Abstract Introduction. The main purpose of this study was to evaluate the effect of a training programme aimed to enhance toe-toboard consistency on footfall variability and performance in the long jump. Material and methods. The study involved 36 male physical education students. The experimental group participated in a 12-week training programme, whereas the control group was limited to taking part in the classes held at university. All participants performed 6 long jump trials during two testing sessions. The kinematic parameters were assessed using the Optojump Next device and were further analysed to determine the variability of footfall placement during the approach run. Results. The analysis revealed a significant (p < 0.01) decrease in footfall variability in the experimental group between the pre-test and post-test. After the completion of the training programme, the participants significantly (p < 0.05) improved their take-off accuracy. Additionally, they significantly (p < 0.05) increased their velocity in the last five steps before take-off and the effective distance of the jump (p < 0.001). Conclusions. The results of this study indicate that through specific training, it is possible to improve the consistency of the steps in the acceleration phase of the approach run in the long jump. Moreover, decreasing footfall variability helps achieve a more stable step pattern which may be beneficial for greater accuracy at the take-off board and makes it possible to increase step velocity at the final stage of the approach run.

The Relationship

The aim of this research was to determine the relationship between pole vault warmup and competition performance in a sample of 16 collegiate vaulters over 60 observations. Pole vault athletes are given time to warm up in the same area that the competition will take place. This prompted investigation into whether better warmup performance could indicate better familiarity with the performance environment, and whether this could translate to the competition. The number of warmup vaults taken was also considered. Participants were observed during multiple warmup periods and data was collected on warmup performance. The findings indicate a significant correlation between instances in which participants displayed their best warmup scores and their best competition performances, likewise with their worst. Also, participants who took more warmup vaults performed significantly better on average. Athletes and coaches should consider implementing warmup practices that emphasize familiarizing oneself with their performance environment.

This study aimed to assess the diet quality of Brazilian Paralympic track-and-field team sprinters and its variation between days. All sprinters (n = 28) were invited, and 20 (13 men and seven women) accepted the invitation consisting of 13 athletes with visual impairment, four with cerebral palsy, and three with limb deficiency. The dietary intake was recorded by photographic register on four consecutive days, and diet quality was determined using a revised version of the Healthy Eating Index for the Brazilian population. Physical activity was assessed using an accelerometer, and metabolic unit information was used to classify exercise intensity. Variance Analysis Model and Bonferroni multiple comparisons were used to assess relationships between variables. The correlations between variables used Pearson linear correlation coefficient. The results show that revised version of the Healthy Eating Index score was classified as “needs to be modified” for all athletes. The maximum score for the components “Whole fruits,” “Total vegetables,” and “Dark green and orange vegetables and legumes” was achieved by 23.1% and 14.3%, 7.7% and 14.3%, and 46.2% and 57.8% of male and female athletes, respectively. Only 38.5% of the male athletes achieved the maximum score for the “Total cereal” component. Female athletes achieved higher scores than male athletes for the “Milk and dairy products” component (p = .03). Intake of whole grain cereals, dairy products, vegetables, and whole fruits needs modifications to improve adequate intake of vitamins and antioxidants, highlighting the need of continuous actions of nutrition education for this population.

The validity and reliability of the Optojump system were investigated for jumping height and flight time in vertical jump tests. Conversely, the purpose of the present study was to investigate the validity and reliability of the Optojump system for measuring contact time and lateral displacement in change of direction and lateral jump tests. Thirty basketball collegiate athletes were tested on two 10 m sprints with a 60° (COD60) or 180° (COD180) change of direction, lateral controlled (CLRJ) and maximal (MLRJ) rebound jump, and lateral countermovement (LCMJ) and squat (LSJ) jump with the concomitant use of two force plates and the Optojump system for the measurement of contact time in COD60, COD180, CLRJ, MLRJ, and lateral jumping distance in all the lateral jump tests. Almost perfect coefficients (r ≥ 0.95) emerged for contact time in COD60, COD180, CLRJ, MLRJ, although a systematic bias was found for COD60 (−0.01 s). Good-to-excellent reliability was found for almost all the measurements of contact time and lateral jumping distance for change of direction and lateral jump tests. Therefore, the use of Optojump system for testing change of direction and lateral jumping abilities should be executed with caution, avoiding misinterpretation of data.
