“…Similar absolute reliability results, although slightly higher, have been reported in previous studies using the same population (recreational athletes) (Li et al, 1996;Dauty & Rochcongar, 2001;Dervisevic et al, 2006;Maffiuletti et al, 2007;Sole et al, 2007;Impellizzeri et al, 2008) but using a different body testing position (seated). For example, Impellizzeri et al (2008) reported within-subject variation expressed throughout standard error of measure (SEM, 68% likely) of 5Á2% for concentric knee flexion PT measured at 180°s À1 , whereas the results of the current study have shown a within-subject variation of 12Á3% for the same isokinetic index.…”

“…Surprisingly, although several studies have examined the absolute reliability of the most common isokinetic parameters under knee flexion and extension muscle actions (McCleary & Andersen, 1992;Li et al, 1996;Pincivero et al, 1997;Dauty & Rochcongar, 2001;Lund et al, 2005;Dervisevic et al, 2006;Maffiuletti et al, 2007;Sole et al, 2007;Impellizzeri et al, 2008), none of them have determined the absolute reliability of PT, APT, PW and TW isokinetic parameters using a prone position during the isokinetic testing protocol. Therefore, the main purpose of this study was to determine the absolute reliability of PT, APT, PW and TW for isokinetic concentric and eccentric knee extension and flexion measured in a prone position at 60, 180 and 240°s À1 in recreational athletes.…”

The main purpose of this study was to determine the absolute and relative reliability of isokinetic peak torque (PT), angle of peak torque (APT), average power (PW) and total work (TW) for knee flexion and extension during concentric and eccentric actions measured in a prone position at 60, 180 and 240° s(-1). A total of 50 recreational athletes completed the study. PT, APT, PW and TW for concentric and eccentric knee extension and flexion were recorded at three different angular velocities (60, 180 and 240° s(-1)) on three different occasions with a 72- to 96-h rest interval between consecutive testing sessions. Absolute reliability was examined through typical percentage error (CV(TE)), percentage change in the mean (ChM) and relative reliability with intraclass correlations (ICC(3,1)). For both the knee extensor and flexor muscle groups, all strength data (except APT during knee flexion movements) demonstrated moderate absolute reliability (ChM < 3%; ICCs > 0·70; and CV(TE) < 20%) independent of the knee movement (flexion and extension), type of muscle action (concentric and eccentric) and angular velocity (60, 180 and 240° s(-1)). Therefore, the current study suggests that the CV(TE) values reported for PT (8-20%), APT (8-18%) (only during knee extension movements), PW (14-20%) and TW (12-28%) may be acceptable to detect the large changes usually observed after rehabilitation programmes, but not acceptable to examine the effect of preventative training programmes in healthy individuals.

“…Briefly, a Biodex System-4 isokinetic dynamometer (Biodex Corp., Shirley, NY, USA) and its respective manufacture software were used to determine isokinetic concentric and eccentric torques during knee extension and flexion actions. Only the dominant leg was tested, as no meaningful differences between legs have been previously reported for sedentary and recreationally active adults [33, 34]. The dynamometer was calibrated according to the manufacturer’s instructions immediately before each test session and verified immediately after to ensure that no changes occurred in sensitivity.…”

Acute Effects of Three Neuromuscular Warm-Up Strategies on Several Physical Performance Measures in Football Players

No studies have analysed the acute effects of the FIFA 11+ and Harmoknee warm-up programmes on major physical performance measures. The aim of this study was to analyse the acute (post-exercise) effects of the FIFA 11+, Harmoknee and dynamic warm-up routines on several physical performance measures in amateur football players. A randomized, crossover and counterbalanced study design was used to address the purpose of this study. A total of sixteen amateur football players completed the following protocols in a randomized order on separate days: a) FIFA 11+; b) Harmoknee; and c) dynamic warm-up (DWU). In each experimental session, 19 physical performance measures (joint range of motion, hamstring to quadriceps [H/Q] strength ratios, dynamic postural control, 10 and 20 m sprint times, jump height and reactive strength index) were assessed. Measures were compared via a magnitude-based inference analysis. The results of this study showed no main effects between paired comparisons (FIFA 11+ vs. DWU, Harmoknee vs. DWU and Harmoknee vs. FIFA 11+) for joint range of motions, dynamic postural control, H/Q ratios, jumping height and reactive strength index measures. However, significant main effects (likely effects with a probability of >75–99%) were found for 10 (1.7%) and 20 (2.4%) m sprint times, demonstrating that both the FIFA 11+ and Harmoknee resulted in slower sprint times in comparison with the DWU. Therefore, neither the FIFA 11+ nor the Harmoknee routines appear to be preferable to dynamic warm-up routines currently performed by most football players prior to training sessions and matches.

“…The application of this ÔfullÕ RoM (FRoM) testing is by no means unique. Recent studies comprising trunk (6), knee (3,4,13) and shoulder (8) muscles have indicated that the use of a much shorter range of joint motion (SRoM) could yield similar findings while preserving subject safety and comfort. Specifically in studies relating to knee flexion and extension strength, an FRoM of 90°was split into 3 short subranges of motion: 0-30°, 30-60°, and 60-90°of flexion.…”

“…The SRoMbased strength scores, particularly those derived from the 30-60°(middle) sector were strongly correlated (r . 0.9) with their FRoM counterparts while evidencing clinically acceptable reproducibility under both concentric and eccentric conditions (4,13). Hence, under the prescribed conditions, SRoM may effectively replace FRoM as the testing technique in normal subjects.…”

The purpose of this study was to compare the utility of measuring wrist flexors and extensors strength derived from 'full' range of motion (FRoM): 60 degrees of flexion to 30 degrees of extension, and 3 equally spaced short ranges of motion: SRoM1, 60-30 degrees and SroM2, 30-0 degrees of flexion and SRoM3, 0-30 degrees of wrist extension. Fifteen apparently healthy subjects and 8 patients suffering from unilateral carpal tunnel syndrome (CTS) participated in the study. In all participants, SRoM1 findings closely resembled those obtained from FRoM. In the patient groups, the muscular strength of the uninvolved side was not different from that of the healthy subjects. On the other hand, based on a bilateral comparison (involved vs. uninvolved hand), the mean total weakness (in concentric and eccentric modes) was significantly higher in flexion (56.4 +/- 17.3%) than in extension (39.8 +/- 15.5%) but highly symmetrical between FRoM and SRoM1. Although supporting the interchangeable use of FRoM and SRoM isokinetic testing, this study highlights a hitherto unreported dynamic weakness of the wrist extension-flexion apparatus that may partly account for the general reduction in hand function reported by patients with CTS.
