“…Velzen et al (2006) investigated the relationship between physical capacity (aerobic capacity, anaerobic capacity, muscle force, flexibility and balance) and walking ability in lower limb amputation and determined a strong positive correlation between walking ability and muscular strength. In addition, a relationship between muscular strength and vertical jump performance (CMJ and SJ) was found by different authors (Çakır et al, 2009; Paasuke et al, 2001; Tsiokanos et al, 2002). Furthermore, Thorland et al (1987) found a significantly strong correlation between isokinetic knee strength and anaerobic power and capacity of female sprinters and middle distance runners.…”

The purpose of the present study was to investigate the relationship between body composition, anaerobic performance and sprint performance of amputee soccer players. Fifteen amputee soccer players participated in this study voluntarily. Subjects’ height, body weight, body mass index, body fat percentage (Jackson and Pollock formula) and somatotype characteristics (Heath-Carter system) were determined. The sprint performance at 10m, 20m and 30m was evaluated, whereas the counter movement jump (CMJ), relative CMJ (RCMJ), squat jump (SJ) and relative SJ (RSJ) tests were used for the determination of anaerobic performance. The results of the Pearson Product Moment correlation analysis indicated that body composition was significantly correlated with CMJ and SJ (p < 0.01), on the other hand, no measure of body composition was significantly related to the other component (p > 0.05). A significant correlation was found between CMJ, RCMJ, SJ, 10 m, 20 m and 30 m sprint performance (p < 0.05); whereas, in contrast, no measure of body composition was significantly related to the 10 m, 20 m and 30 m sprint performance (p > 0.05). In conclusion, the findings of the present study indicated that sprint performance was described as an essential factor in anaerobic performance whereas body composition and somatotype play a determinant role in anaerobic and sprint performance in amputee soccer players.

“…20 Isokinetic strength may serve as a valuable predictor of jumping performance, but the findings of current literature are controversial. 21 For instance, some authors demonstrate moderate to strong relationships between isokinetic knee measures and jumping performance, [22][23][24][25] while others report low or negligible associations. 26,27 However, it is evident that most of the research in this area has focused on non-specific jumps such as squat-jump and CMJ, even those studies that have included well trained, competitive athletes.…”

“…Isokinetic devices are used for training and testing purposes due to their unique contraction conditions [5][6][7][8], rehabilitative and preventive application possibilities [9][10][11][12][13][14] as well as their predictive power in relation to several sport-specific capabilities [15][16][17][18][19]. Reliability rep-resents an important quality criterion of measurement instruments for research and performance diagnostics.…”

BACKGROUND: Although the reliability of isokinetic strength tests of knee flexors (flex) and extensors (ext) has been examined several times, statistical evidence about the influence of internal and external factors is missing. OBJECTIVE: This study aims to examine the impact of familiarisation, muscle group, contraction mode, angular velocity and test parameters on the reproducibility of findings derived from an isokinetic dynamometer (IsoMed 2000). METHODS: Thirty-three male subjects (mean age: 22.3 years) with no prior experience of isokinetic exercise participated in three identical test sessions (T1, T2, T3), each separated by 48-72 h. Peak moment (PM), angle of peak moment (APM) and contractional work (CW) were determined unilaterally (left and right) during maximum concentric (con) and eccentric (ecc) knee flexion (abdominal position) and extension (supine position) at 30, 90 and 150 • /s, respectively. An ANOVA with repeated measures confirmed systematic bias. Reproducibility of consecutive tests (T1-T2, T2-T3) was assessed by calculating the intra-class correlation coefficient (ICC 2,1) (relative reliability) as well as the standard error of measurement (SEM) (absolute reliability). ICC values were averaged according to respective factors (Fisher's z-transformation) and tested for significant differences by Steiger's formulas. RESULTS: PM and CW demonstrated a high absolute reliability (SEM: 4.7-10.5%). Relative reproducibility varied considerably (p 0.05) between muscles (ecc flex > ecc ext), contraction modes (con ext > ecc ext) and test parameters (PM = CW > APM), but did not depend on angular velocity (30 = 90 = 150 • /s). Due to familiarisation the reliability of PM obtained from eccentric knee extensions significantly increased (T2-T3 > T1-T2). CONCLUSIONS: These results improve the development and execution of reliable isokinetic strength testing protocols for unilateral knee flexion and extension together with the interpretation of different test parameters.
