The Effect of an 8-Week Rope Skipping Intervention on Standing Long Jump Performance

Abstract

The purpose of this study was to explore the utility of an 8-week rope skipping intervention in enhancing standing long jump performance was assessed by means of specific kinematic parameters acquired by 3-D space photography. The fifteen male college students from the physical education institute were randomly recruited as the research subjects. Participants first completed a standing long jump test without rope skipping intervention. Participants subsequently took part in a second standing long jump test after rope skipping training. Two high-speed digital cameras with 100 Hz sampling rate were synchronized to capture the movement. The captured images were processed using motion analysis suite, and the markers attached to joints on images were optical auto capture. Based on the results, the velocity of the center of gravity at take-off and landing were significantly improved. In addition, the study confirmed the requirement for forward tilt of the hip joint at landing to increase the velocity of the center of gravity and hence long jump distance. The detailed kinematic analysis described here provided further evidence of the benefits of integrating non-specialized and specialized training activities to enhance athletic performance and offers a contribution to movement theory and practice.

The Effects of Regional Muscle Strength and Mass on Standing Long Jump Performance

“…The dependence of the SLJ distance on the speed and angle of movement of the center of gravity has been previously reported [17]. We need to increase the speed of movement at the center of gravity and keep the hip joint anteriorly tilted during takeoff, while the thighs should be pulled in during landing [18]. Ashby et al used optimal control simulations to show that arm swinging during SLJ generates greater work in the upper extremity muscles and effectively transfers energy to the lower extremities [11].…”

“…This does not mean that lower limb muscle strength is unaffected in SLJ. In SLJ, adjustments in movement and technical skills influence the final performance results [18]. The adjustment aspect may have influenced the selection of trunk and upper limb strength as the optimal models in this study.…”

Evaluación y prescripción del salto vertical y horizontal en futbolistas. Revisión narrativa (Assessment and prescription of vertical and horizontal jumping in soccer players. Narrative review)

“…El salto horizontal es utilizado para medir la fuerza explosiva de las extremidades inferiores en la aplicación de fuerza horizontal (Maulder & Cronin, 2005). Se divide en tres fases: (1) despegue; momento en el que los pies dejan de tocar el suelo: (2) fase de vuelo; desde el instante en que los pies dejan el suelo hasta que los pies aterrizan en el suelo: (3) aterrizaje; el instante en que los pies aterrizan en el suelo (Chen & Wu, 2022) La mayor optimización del rendimiento se obtiene cuando los participantes coordinan la fuerza de los músculos de las extremidades inferiores y de la cadera junto con un movimiento de balanceo de las extremidades superiores (Chen & Wu, 2022). Existiendo una interrelación entre el ángulo de la articulación, el centro de gravedad y la velocidad del centro de gravedad en el despegue y durante la fase de vuelo (Mackala, Stodoka, Siemienski, & Coh, 2013).…”

Analysis and System Construction of ALSTM-LSTM Model-based Sports Jumping Rope Movement

“…The LSTM network fuses static and dynamic features when classifying action recognition. Changes in different nodes can have an impact on action pose recognition, and degree discrimination of node importance can effectively highlight the information data of valid actions, so the study introduces an attention mechanism for weighting [26][27][28]. The attention mechanism assigns different weight values to different input feature sequences to show the difference in their attention, which can effectively improve the LSTM network to treat different feature states the same, ignoring the multi-dimensionality and hierarchy of features.…”
