Simulation of a dynamic vertical jump

Robotica, 2001
The aim of this paper is to propose a bipedal structure able to follow high acceleration movements. The vertical jump of a human has been chosen as input (coming from experiments) to validate the controller design as it is one of the most complex motion.

The effects of drop vertical jump technique on landing and jumping kinetics and jump performance

Journal of Electromyography and Kinesiology, 2021
The drop vertical jump is a popular plyometric exercise. Two distinct techniques are commonly used to initiate the drop vertical jump. With the 'step-off' technique, athletes step off a raised platform with their dominant limb, while their non-dominant limb remains on the platform.

Performing the vertical jump: Movement adaptations for submaximal jumping

Human Movement Science, 2004
The purpose of this study was to gain insight into the kinematics and kinetics of the vertical jump when jumping for different heights and to investigate movement effectiveness as a criterion for movement control in submaximal jumping. In order to jump high a countermovement is used and large body segments are rotated, both of which consume energy ...

Association between traditional standing vertical jumps and a soccer‐specific vertical jump

European Journal of Sport Science, 2012
AbstractThe present study aimed to determine the relationships between a soccer‐specific vertical jump (ssVJ) test, that included common elements of a soccer VJ (e.g. run‐up and intention to head), and three traditional VJ tests using elite soccer players.

Vertical Jump and Power

Strength & Conditioning Journal, 2012
SUMMARYPOWER AND JUMPING ABILITY CORRELATE WITH SPORT PERFORMANCE. IMPROVING MAXIMAL FORCE AND/OR VELOCITY INCREASES POWER PRODUCTION, AND THEREFORE THEORETICALLY ENHANCES GAME PLAY. COACHES AND RESEARCHERS ALIKE ACKNOWLEDGE THAT BOTH JUMPING SPECIFIC (E.G., PLYOMETRICS) AND NONJUMPING ACTIVITIES ...

Tests of Vertical Jump

Strength & Conditioning Journal, 2012
SUMMARYTHE AIM OF THIS ARTICLE IS TO ADAPT 2 VERTICAL JUMP TESTS OF LARGE COORDINATIVE COMPLEXITY AND LARGE DEMAND FOR THE NEUROMUSCULAR SYSTEM AND PROPOSE STANDARD PROTOCOLS THAT PERMIT THE COMPARISON OF RECORDED DATA FROM DIFFERENT STUDIES.

Coordination of segments in the vertical jump

Medicine & Science in Sports & Exercise, 1986
Three general patterns of segmental coordination (i.e., sequential [SEQ], simultaneous [SIM], and modified simultaneous [MSIM]) have been hypothesized for jumping. The purposes of this study were to describe the pattern of segmental coordination used in vertical jumping and to determine if skilled jumpers displayed distinguishing patterns of ...

Effects of Isometric Training on Vertical Jumping

Research Quarterly. American Association for Health, Physical Education and Recreation, 1964
Abstract Sixty-three college men were divided into two equated groups on the basis of their initial ability to exert isometric force upward against shoulder pads of a specially constructed device. Measurements were made and the apparatus adjusted to fit each subject so that the knees were flexed to the angle at which a vertical jump is usually ...

The effects of arms and countermovement on vertical jumping

Medicine & Science in Sports & Exercise, 1990
Countermovement and arm-swing characterize most jumping. For determination of their effects and interaction, 18 males jumped for maximal height from a force platform in all four combinations of arm-swing/no-arm-swing and countermovement/no-countermovement. For all jumps, vertical velocity peaked 0.03 s before and dropped 6-7% by takeoff.

Contributive Components in the Vertical Jump

Research Quarterly. American Association for Health, Physical Education and Recreation, 1968
Abstract The degree of contribution to performance of the vertical jump by leg components plantar flexors, knee extensors, and hip extensors was determined experimentally and tested by analysis of covariance. One control and four experimental groups from 100 college men at Brigham Young University were randomly assigned to varying muscle strengthening ...
