“…Further statistical analysis have shown extremely high level of reliability of the given contractile characteristic RFDmax of hand grip in all of the tested age groups on ICC level from 0.903 to 0.971 for non-dominant hand, and from 0.948 to 0.964 for dominant hand ( Table 3). As in the case of F max these results are in con rmation with the early established standards in relation to the reliability of methods for testing the explosive hand grip force where the ICC levels from 0.870 to 0.930 (Demura et al, 2003;Jenkins et al, 2014) i.e. in accordance with the high reliability of the standard tests of force of the other muscular groups leveled from 0.808 to 0.945 Cronbach's Alpha for the standard leg thrist (Ivanovic and Dopsaj, 2013).…”

“…Даље статистичке анализе су показале изузетно висок ниво поу-зданости испољавања дате контрактилне карак-теристике RFD max стиска шаке код свих тестира-них узрасних група и то на нивоу ICC од 0.903 до 0.971 за недоминантну руку, односно од 0.948 до 0.964 ICC за доминантну руку (Табела 3). Као и у случају F max и ови резултати су у сагласности са претходно утврђеним стандардима у односу на поузданост методе за тестирање испољавања ек-сплозивне јачине стиска шаке где је ICC на нивоу 0.870-0.930 (Demura et al, 2003;Jenkins et al, 2014), односно у складу са високом поузданошћу стан-дардних тестова јачине и код осталих мишићних група на нивоу од 0.808-0.945 Cronbach's Alpha за стандардни потисак ногама (Ivanovic and Dopsaj, 2013). На основу досадашњих истраживања, али и добијених резултата овог истраживања, показа-ло се да је примена изометријског тестирања, а у односу на мерење максималне експлозивне јачи-не код теста "стиска шаке" поуздан и у функцији различитог узраста испитаника код мушкараца.…”

ABSTRACTe aim of the research is to determine the reliability of testing various contractile functions of a male hand based on motoric and functional dominance and age. e examinee takes a seat with their arm extended or mildly exed in a mildly abducted position. For the measuring purposes, dynamometric probe with isometric straining conditions xed to a special construction was used. e "Isometrics" (ver. 3.1.1) was used and frequency of data selection was realized on the level of 500 Hz. e sample includes 269 male examinees aged from 14.0 to 69.9. e results of descriptive statistics have shown that in relation to the tested sample for the non-dominant hand, values for maximum force (F max ) range from 462.8 to 529.0 N, for explosive force (RFD max ) the range is from 1621.6 to 1972.8 N/s and for muscular force impulse (I mp F 50%max ) from 8203.9 to 15552.3 Ns, while F max values the dominant hand ranges from 478.1 to 566.2 N, for RFDmax it ranges from 1742.6 to 2119.0 N/s and for I mp F 50%max 9516.7 to 16845.1 Ns. e results have shown that it is reliable to measure all three examined contractile hand characteristics where by ICC ranges from 0.938 to 0.977 for F max , from 0.903 to 0.971 for RFD max and from 0.747 to 0.943 for I mp F 50%max . e second try as the better result should be considered the representational value for F max and RFD max variables, regardless of the hand dominance or age group. While for the variable I mp F 50%max , in the age groups from 35.0 to 49.9 and from 50.0 to 69.9, the rst tested try for both hands should be considered, in 14.0 to 19.9 years group the second try should be taken into consideration, and in 20.0 to 34.9 age range, the better result of the non-dominant hand is the rst try, and of the dominant is the second try.

SummaryBackground: Lower extremity muscle mass, strength, power, and physical performance are critical determinants of independent functioning in later life. Isokinetic dynamometers are becoming very common in assessing different features of muscle strength, in both research and clinical practice; however, reliability studies are still needed to support the extended use of those devices. Objective: The purpose of this study is to assess the test-retest reliability of knee and ankle isokinetic and isometric strength testing protocols in a sample of older healthy subjects, using a new and untested isokinetic multi-joint evaluation system. Methods: Sixteen male and fourteen female older adults (mean age 65.2 ± 4.6 years) were assessed in two testing sessions. Each participant performed a randomized testing procedure that includes different isometric and isokinetic tests for knee and ankle joints. Results: All participants concluded the trial safety and no subject reported any discomfort throughout the overall assessment. Coefficients of correlation between measures were calculated showing moderate to strong effects among all testretest assessments and paired-sample t test showed only one significant difference (p<0.05) in the maximal isokinetic bilateral knee flexion torque.

“…Although research has demonstrated lower levels of CRP among individuals with greater muscular strength [10], no study to our knowledge has investigated the relationship between muscular strength and CRP across different body mass index (BMI) levels. Furthermore, the majority of studies have used grip strength when examining the relationship between muscular strength and health outcomes; however, there has been conflicting evidence regarding the functional importance of this measurement [18]. Specifically, it has been suggested that grip strength may not serve as a surrogate for balance or dynamic assessment of lower body strength [18].…”
