“…These specific demands could lead to the development of asymmetric adaptations between legs. The results in the present investigation were similar to other studies (Ceroni et al, 2012; Meylan et al, 2010), who found significant differences between limbs in unilateral jump capacity. Evidence in the existing literature is, however, equivocal as some previous research (Hewit et al, 2012; Schiltz et al, 2009) demonstrated no significant difference in unilateral vertical jump capacity in healthy athletes.…”

The primary objective of the present study was to evaluate the agreement between the dominant leg (DL) (determined subjectively) and the stronger leg (SL) (determined via a functional test) in a group of basketball and volleyball players. The secondary objective was to calculate lower limb neuromuscular asymmetry when comparing the DL vs the non-dominant leg (NDL) and the SL vs the weaker (WL) leg in the whole group and when differentiating by sex. Seventy-nine male and female volleyball and basketball players (age: 23.7 ± 4.5 years) performed three single-leg vertical countermovement jumps (SLVCJ) on a contact mat. Vertical jump height and an inter-limb asymmetry index (ASI) were determined. Only 32 (40%) of the subjects had a concordance between the perception of their dominant leg and the limb reaching the highest jump height. Using the DL as the discriminating variable, significant (p<0.05) inter-limb differences were found in the total group of players. When comparing between sexes, significant differences (p<0.05) arose in the female group only. With regard to the WL vs. the SL, significant (p<0.05) differences were noted in the whole group and when stratified into males and females. The mean ASI ranged from 9.31% (males) to 12.84% (females) and from 10.49% (males) to 14.26% (females), when comparing the DL vs. the NDL and the SL vs. the WL, respectively. Subjective expression of leg dominance cannot be used as a predictor of limb jump performance. Vertical jump asymmetry of 10-15% exists and this can be considered as a reference value for male and female basketball and volleyball players.

“…Correlation of the indices of all jumps (Table 4) has confi rmed already known facts from our and other authors' research [4,7,8,18,25], and also revealed some not very well-known causal relations. It was found that with the increase of body mass, duration of the takeoff phase becomes longer (r = 0.54, p<0.05) and body movement speed decreases (r = -0.45, p < 0.05).…”

SummaryAn athlete moves as an integral biomechanical system, yet depending on the specifics of a specific sports discipline, the activity of certain body parts is different. The performance of athletes in different track-and-field events and sports is determined by coordinative interaction of the legs, hands and other body parts, thus possible differences in their biodynamic structure and functional abilities may be assessed based on identical indices.Research aim. To determine kinematic and kinetic indices of a single vertical take-off and push-off of 20-23 year old male athletes engaged in track-and-field athletics (sprint and long jump) and sports (handball and basketball).Object of research. Studying the movement of athletes [track-and-field athletics (sprint and long jump) and sports (handball and basketball)] during a single vertical take-off and push-off.Research methods. 1. Tensodynamometry; 2. Mathematical statistics. Data processing carried out using SPSS software (version 13.0).Research results. All kinematic and kinetic indices of a single vertical take-off and push-off of track-andfield athletes are similar to the ones of handball and basketball players, yet (p < 0.05) only the one of relative power (Wr, N/m/s/kg) is reliably better. When comparing the jump flight and height indices of the track-and-field athletes with basketball players, those indices are statistically reliably lower for the track-and-field athletes, yet the relative power of the single vertical take-off and push-off is higher (p < 0.05, p < 0.001). The basketball players' speed of body movement is reliably higher (p < 0.05) than for the handball players. The kinematic and kinetic indices of the single vertical take-off using both legs in all the three groups was reliably better (p < 0.001) when compared to the same indices of the single vertical push-off.The alteration of the quantitative ratio of those indices depends on the sports discipline specifics and reveals the level of individual motor abilities and body movement potential.

A Brief Review of Strength and Ballistic Assessment Methodologies in Sport

et al. 2014

An athletic profile should encompass the physiological, biomechanical, anthropometric and performance measures pertinent to the athlete's sport and discipline. The measurement systems and procedures used to create these profiles are constantly evolving and becoming more precise and practical. This is a review of strength and ballistic assessment methodologies used in sport, a critique of current maximum strength [one-repetition maximum (1RM) and isometric strength] and ballistic performance (bench throw and jump capabilities) assessments for the purpose of informing practitioners and evolving current assessment methodologies. The reliability of the various maximum strength and ballistic assessment methodologies were reported in the form of intra-class correlation coefficients (ICC) and coefficient of variation (%CV). Mean percent differences (Mdiff = [/Xmethod1 - Xmethod2/ / (Xmethod1 + Xmethod2)] x 100) and effect size (ES = [Xmethod2 - Xmethod1] ÷ SDmethod1) calculations were used to assess the magnitude and spread of methodological differences for a given performance measure of the included studies. Studies were grouped and compared according to their respective performance measure and movement pattern. The various measurement systems (e.g., force plates, position transducers, accelerometers, jump mats, optical motion sensors and jump-and-reach apparatuses) and assessment procedures (i.e., warm-up strategies, loading schemes and rest periods) currently used to assess maximum isometric squat and mid-thigh pull strength (ICC > 0.95; CV < 2.0%), 1RM bench press, back squat and clean strength (ICC > 0.91; CV < 4.3%), and ballistic (vertical jump and bench throw) capabilities (ICC > 0.82; CV < 6.5%) were deemed highly reliable. The measurement systems and assessment procedures employed to assess maximum isometric strength [M(Diff) = 2-71%; effect size (ES) = 0.13-4.37], 1RM strength (M(Diff) = 1-58%; ES = 0.01-5.43), vertical jump capabilities (M(Diff) = 2-57%; ES = 0.02-4.67) and bench throw capabilities (M(Diff) = 7-27%; ES = 0.49-2.77) varied greatly, producing trivial to very large effects on these respective measures. Recreational to highly trained athletes produced maximum isometric squat and mid-thigh pull forces of 1,000-4,000 N; and 1RM bench press, back squat and power clean values of 80-180 kg, 100-260 kg and 70-140 kg, respectively. Mean and peak power production across the various loads (body mass to 60% 1RM) were between 300 and 1,500 W during the bench throw and between 1,500 and 9,000 W during the vertical jump. The large variations in maximum strength and power can be attributed to the wide range in physical characteristics between different sports and athletic disciplines, training and chronological age as well as the different measurement systems of the included studies. The reliability and validity outcomes suggest that a number of measurement systems and testing procedures can be implemented to accurately assess maximum strength and ballistic performance in recreational and elite athletes, alik...
