Mirkov, DM, Nedeljkovic, A, Kukolj, M, Ugarkovic, D, and Jaric, S. Evaluation of reliability soccer-specific field tests. J Strength Cond Res 22: 1046-1050, 2008-The tests are popular among coaches due to their simplicity, validity, minimal use equipment. Nevertheless, there is a general lack data about reliability, particularly regarding the anaerobic performance. Twenty professional male soccer players performed 3 consecutive trials throwing-in standing-kick performance (the distance...

The aim of this study was to assess the effect a unilateral anterior cruciate ligament reconstruction (ACLR) on maximum voluntary contraction (MVC) and explosive strength both involved limb uninvolved limb. Nineteen male athletes completed standard isometric testing protocol 4 months post-ACLR, while 16 healthy participants served as control group (CG). knee extensors flexors assessed RFD obtained from slope force-time curves over various time intervals. Both muscle groups had significantly...

Employee well-being and affective states are critical factors influencing overall organizational success. This study examined the immediate effects of a sensory-enhanced acute exercise program on employees' characteristics, including emotions, anxiety, work motivation; A total 84 participants, split into an experimental control group, participated in actual study. The group engaged 14-min tailored sensory-rich "smart room" while watched neutral animated documentary. pretest-posttest design...

The purpose of the study was to explore effect maturation on body size–physical performance relationship. Based our previous that evaluated only muscle strength (16), we hypothesized physical tested pubescent subjects would be related size at a higher rate than predicted by standard scaling theory applied pre- and postpubescent subjects. Six age groups highly selected trained junior soccer players (N = 478; 12–17 years) presumably including prepubescent, pubescent, were evaluated. They using...

To explore the effects of training against mechanically different types loads on muscle force (F), velocity (V), and power (P) outputs.Subjects practiced maximum bench throws over 8 wk a bar predominantly loaded by approximately constant external (weight), weight plates (weight plus inertia), or whose was compensated pulling upward (inertia). Instead typically applied single trial performed selected load, pretest posttest consisted same task ranging from 30% to 79% subject's strength adding...

Abstract Single outcomes of standard isokinetic dynamometry tests do not discern between various muscle mechanical capacities. In this study, we aimed to (1) evaluate the shape and strength force-velocity relationship knee extensors, as observed in conducted at a wide range angular velocities, (2) explore concurrent validity simple 2-velocity method. Thirteen physically active females were tested for both peak averaged extensor concentric force exerted velocities 30°–240°/s recorded 90°–170°...

Abstract This study aimed (I) to investigate the impact of number stimulus‐responses alternatives on reaction time (RT) under quasi‐realistic fencing situations, and (II) elucidate whether regression slope based RT could distinguish between beginners experienced fencers. Ten (7 men) 10 (6 fencers participated in study. A video‐based method was used present four typical movement techniques (i.e. “stimulus”) after which participants had perform an offensive (high or low attack) defensive...

The effect of body size on the output tests directly assessed muscle power has been mainly ignored in applied research. We hypothesized that would reveal a positive relationship with closely line theoretical predictions, as well strength studied could justify standardized normalization procedures routine testing. Male physical education students (n = 111) were evaluated 10 standard direct assessment output. A allometric P Sb was to assess between tested and selected indices S (b exponent;...

AbstractThe aim of the study was to evaluate a novel Video-based method for testing reaction time (RT) in specific sport situations. The participants were elite karate kumite competitors and beginners. Two realistic responses (upper lower blocks) under conditions known advance (Simple RT condition) or unknown (Choice stimuli (video recordings either kick punch presented front subject) recorded by 3D motion analysis system. tested proved be highly reliable both groups, responses, conditions,...

J Strength Cond Res 25(6): 1605-1615, 2011—Although regularly used, the standard strength (SST) is known to have several shortcomings, such being based only on sustained forces, relatively large number trials that expose tested rapid fatigue. The purpose this study was evaluate alternating (ACMCs) function through its comparison with SST. Twenty-four participants...

The present study explored the method of testing muscle mechanical properties through linear force-velocity (F-V) relationships obtained from loaded vertical jumps. Specifically, we hypothesised that F-V relationship parameters depicting force, power, and velocity tested muscles will differ among individuals different physical fitness. Strength trained, physically active, sedentary male participants (N = 10 + 10; age 20-29 years) were on maximum countermovement squat jumps where manipulation...

The aim of the present study was to determine if an inertial measurement unit placed on metatarsal part foot can provide valid and reliable data for accurate estimate vertical jump height. Thirteen female volleyball players participated in study. All were members Republic Serbia national team. Measurement height performed two exemplary jumping tasks, squat counter-movement jump. Vertical estimation using flight time method both devices. presented results support a high level concurrent...

Introduction. Maximal strength ratios such as the limb symmetry index (LSI) and hamstring-to-quadriceps ratio (HQ) may be considered main outcome measures in monitoring of recovery after anterior cruciate ligament (ACL) reconstruction. Although explosive is much more important than maximal strength, it generally disregarded follow-up muscle function recovery. Objective. The purpose this study was to compare between (Fmax) (rate force development - RFD) individuals with ACL Methods. Fifteen...

The ability to change swimming styles and body positions, involving continuous shifting from horizontal vertical posture performing jumps, as well technical skills play a fundamental role in water polo performance. To face with these demands, the coaching staff of elite sub-elite clubs might adopt variety training methods, also based on their specific philosophies. This point has led an enlargement staff, higher head coaches’ responsibilities, who may interpret professional activity...
