In this paper, we consider the soliton cellular automaton introduced in [21] with a random initial configuration. We give multiple constructions of a Young diagram describing various statistics of the system in terms of familiar objects like birth-and-death chains and Galton-Watson forests. Using these ideas, we establish limit theorems showing that if the first n boxes are occupied independent...

Background. This study aimed to analyze core muscle fatigue effects on the kinematic parameters change during volleyball jump serve. Methods. The participants were sixteen experienced male volleyball players with average age, height, and body weight of 24.6 ± 1.8 years, 1.85 ± 1.6 m, and 79.5 ± 3.5 kg, respectively. This study utilized two high-resolution video cameras, a drone video, a lactat...

We use a large single particle tracking data set to analyze the short time and small spatial scale motion of quantum dots labeling proteins in cell membranes. Our analysis focuses on the jumps which are the changes in the position of the quantum dots between frames in a movie of their motion. Previously we have shown that the directions of the jumps are uniformly distributed and the jump length...

abstract in this study, the effect of suspended load transport on the characteristics of submerged hydraulic jump (shj) in a rectangular channel was investigated experimentally. sediment concentration and jet froude numbers in the range of 0.424%-16.15% and 1.93-4.96, respectively, were considered. tow grain size 0.15 and 0.03 mm were used in the experiments. characteristics of submerged hydrau...

BACKGROUND Double-leg forward or drop-jump landing activities are typically used to screen for high-risk movement strategies and to determine the success of neuromuscular injury prevention programs. However, research suggests that these tasks that occur primarily in the sagittal plane may not adequately represent the lower extremity biomechanics that occur during unilateral foot contact or non-...

High-impact exercise has been considered an important method for treating bone loss in osteopenic experimental models. In this study, we investigated the effects of osteopenia caused by inactivity in femora and tibiae of rats subjected to jump training using the rat tail suspension model. Eight-week-old female Wistar rats were divided into five groups (n=10 each group): jump training for 2 week...

PURPOSE Running at high speed and sudden change in direction or activity stresses the knee. Surprisingly, not many studies have investigated the effects of sprinting on knee's kinetics and kinematics of soccer players. Hence, this study is aimed to investigate indices of injury risk factors of jumping-landing maneuvers performed immediately after sprinting in male soccer players. METHODS Twen...

this study aimed at investigating the effect of bcaas consumption on wrestlers' creatine kinase (ck) activity in a three-month depth jump exercise. for this purpose, 22 male wrestlers from zanjan province (age 21.54±3.52 yr, weight 66.18±3.76 kg, height 168.36±2.41 cm, bmi 23.34±1.97 kg/m2) were randomly selected and divided into two groups. during the mentioned period, both groups had the...

This study aims to analyze: (1) The differences in the influence of squat jump style on participants athletics extracurricular who undergo alternate leg bound plyometric training and double training. (2) interaction between lower limb power style. (3) results for with high power. (4) low research method used is a quasi-experimental design 2x2 treatment by level factor design. sample size was 40...

there is a substantial evidence that plyometric training significantly increases muscular strength and vertical jump. due to the vigorous nature of this type of training, however, there is a risk of incurring musculoskeletal injuries. therefore, conducting plyometric exercise programs in an aquatic environment might lead to significant improvements in vertical jump with possibly a lower risk of...
