“…Compared to past research (Panoutsakopoulos et al, 2017), the flight to support time ratio at the penultimate step recorded at the present study was of similar magnitude as in male long jumpers. The temporal parameters of the last steps of the approach are suggested to characterise the effectiveness of the jumper's technique in the preparation for take-off (Hay and Nohara, 1990;Shimizu et al, 2011).…”

“…The values of parameters identifying the technique elements at take-off (i.e., knee extension angle) are suggested to be similar between men and women (Linthorne, 2008;Panoutsakopoulos and Kollias, 2009). On the opposite, female long jumpers were found to perform with lower take-off velocities compared to males (Akl, 2014;Hay and Miller, 1985;Nemtsev et al, 2016;Panoutsakopoulos et al, 2017). Another gender difference is the fact that female long jumpers rely primarily on a higher vertical take-off velocity rather than attaining a higher horizontal take-off velocity (Letzelter, 2011).…”

“…The current knowledge about the long jump is acquired from biomechanical analyses conducted in major international competitions (Arampatzis and Brüggemann, 1999;Mendoza and Nixdorf, 2011;Panoutsakopoulos et al, 2017;Tucker et al, 2018). The relationship among those parameters and long jump performance is mainly examined with correlation analysis (Hay and Miller, 1985;Luhtanen and Komi, 1979), regression analysis (Graham-Smith and Lees, 2005;Letzelter, 2011;Nemtsev et al, 2018) and factor analysis (i.e., Principal Components Analysis, Campos et al, 2013b;.…”

Aim of the study was to provide evidence concerning the biomechanical parameters of contemporary Women's long jump in indoor competition. The final six steps and the take-off of 11 jumps (6.88 ± 0.23 m) were recorded (panning camera; sampling frequency: 300 fps) in an indoor competition. The examined parameters were a) the step parameters, the percentage distribution of adjustment (ADJ%) and the inter-limb symmetry angle (θSYM) in the late approach, b) the joint angles and the take-off parameters. Pearson's correlation analysis revealed that approach velocity (9.8 ± 0.3 m/s) was significantly correlated (r = .86, p = .001) with effective distance (6.96 ± 0.23 m). The largest ADJ% (57.6 %) was executed at the penultimate step which was 12.2 ± 2.8 % larger than the last step. An inter-limb difference was revealed for step frequency (t10 = 6.965, p < .001) due to the large asymmetry observed (θSYM = 5.54 deg). The knee angle of the push-off leg at take-off was 171.2 ± 4.7deg. Resultant velocity (8.3 ± 0.4 m/s), height (1.15 ± 0.05 m) and angle (20.7 ± 2.3 deg) of take-off significantly predicted effective distance (F3,7 = 12.671, p = .003, R 2 = .844). The present findings are in reasonable agreement with previous research. Future studies should examine the possible reliance and asymmetry for the step parameters in the final approach.

“…An insuperable constrain for IIJ athletes seems to be the attainment of high velocity while negotiating the target. Although there is evidence that suggests that the physical qualities of II athletes are similar to those of active individuals without II (Van de Vliet et al, 2006), the examined IIJ failed to achieve velocities similar to those of elite male jumpers without II during the approach run (Panoutsakopoulos et al, 2017).…”

“…The rationale for not selecting male long jumpers without II was because male athletes achieving similar jumping distances (approximately 6.50 m) are considered to be of lowperformance level. On the other hand, female long jumpers performing over 6 m are classified as high-level athletes that are considered to master the technical requirements of the event and attain approach velocities comparable to those of elite male T20 long jumpers (see Panoutsakopoulos et al, 2017). Furthermore, to the best of our knowledge, there is no evidence in the literature to suggest differences in visual control and perception ability between males and females in the long jump.…”

Long jump has been extensively used in the investigation of perceptionaction coupling. The restraints imposed by the tasks nested at the take-off board compel skilled long jumpers to adjust the length of the final 4-5 steps of the run-up based on visual input informing about time-to-arrival. This exploratory study examined the visual regulation parameters in athletes with intellectual impairment (II) during the approach of the long jump. The approach run of 10 elite level T20 Class long jumpers (IIJ) and 10 international level long jumpers without II (NIJ) was recorded during competition. An initial ascending variability of foot placement was observed for both groups, followed by a descending one in the late phase of the approach. The parameters associated with the onset of visual control for IIJ were found to be not statistically significantly different to those of NIJ. The mean maximum toe-board distance variability was 0.38 m and 0.27 m for IIJ and NIJ, respectively. The onset of regulation commenced at the fifth-and third-to-last step for IIJ and NIJ, respectively. The finding that IIJ adjust the last steps of the run-up with sufficient accuracy suggests the presence of visual control. This information can be used to optimize long jump approach run training for athletes with II.

The aim of the study was to examine the inter-limb asymmetry in force application in a 1-s maximum isometric leg press test (ISOM) and vertical jump tests without an arm swing (VJ)of male long jumpers. Nine experienced jumpers (age: 18–30 y, LJ personal best: 6.50–8.05 m) were examined. Participants performed: (a) bilateral VJs from the squatting position (SQJ) and with a countermovement (CMJ), (b) unilateral CMJ from the take-off (TOL) and swing (SWL) leg used in the LJ take-off, and c) bilateral 1-s ISOM tests. Data were collected for each lower limb with separate force dynamometers (sampling frequency: VJs = 1 kHz, ISOM = 500 Hz). The inter-limb asymmetry of the peak applied force was evaluated using the symmetry angle. The paired samples T-test revealed non-significant (p > 0.05) inter-limb differences for the force output in the bilateral jump tests, in the unilateral jump tests, and in the ISOM. In conclusion, despite the fact that a powerful unilateral take-off is required for the optimization of long jump performance, no asymmetry was found in the examined tests, suggesting that the dominant/take-off leg was not stronger than the contra-lateral leg. This is possibly due to the intensive execution of other bilateral tasks involved, like the approach run.
