  • Purpose: The purpose of this study was to evaluate the effectiveness of three functional performance tests and one-legged hop test and to establish the reference data of the three functional performance tests of the active young Korean men. Materials and methods: We performed five tests on 40 normal subjects such as one-legged hop test (single hop, triple hop) and the three functional performance tests (carioca test, co-contraction test, shuttle run test). The mean age was 28.4 years. The mean score of Tegner activity scale was 6.2 and Lysholm score 98.2 Mean value and standard deviation were obtained. The correlation of age, height and weight with the results, the relationship between FPT and one-legged hop test and the mean difference between dominant and non-dominant limbs were statistically calculated. Results: All data obtained were normally distributed and there were no significant relationship between age, height and weight. The paired t-test of one legged hop test showed no statistical significance between dominant and non-dominant limbs. The results of one legged hop test had strong relationship with functional performance test. Conclusion; The three functional performance tests can be a useful functional test in ACL-insufficient athletes. Our results can be used as normal reference data of the normal active Korean men.

  • Purpose: The goal is to identify the effectiveness of the IKDC subjective score in the clinical outcome study after reconstruction of the anterior cruciate ligament. Materials and Methods: Twenty-four patients after ACL reconstructions using twelve hamstring autografts and twelve Achilles allografts were evaluated. Lysholm knee score, IKDC subjective score, Knee Outcome Survey score and Tegner activity score were evaluated for the subjective outcome value. Static instability tests, Biodex dynamometer and one-legged hop for distance tests were done for the objective outcome value. Three functional performance tests (FPTs) including Carioca test, Shuttle run test and Co-contraction test were performed for deciding the final results. Each scale was compared with FPTs results and Pearson's correlation test was used to test the correlation between the parameters. Results: IKDC subjective score, single hop test, and quadriceps power in low velocity of Biodex dynamometer tests had a positive correlation with the total FPTs results. Conclusion: IKDC subjective score can be an effective test to evaluate the functional status as well as the subjective outcome after ACL reconstruction.

  • The technology of distinguishing human motion states is required in the areas of measuring and analyzing biosignals changing according to physical activities, diagnosing sleep disorder, screening the effect of treatment, examining chronic patients' kinetic state, prescribing exercise therapy, etc. The present study implemented a fuzzy inference system based on fuzzy rules that distinguish human motion states (tying, sitting, walking, and running) by acquiring and processing data of LAA, TAA, L-MAD, and T-MAD using ADXL202AE of Analog Devices embedded in an armband. The membership degree and fuzzy rules in each area of input (LAA, TAA, L-MAD, and T-MAD) and output (tying, sitting, walking, and running) data used here were determined using numeric data obtained from experiment. In the results of analyzing data for simulation generated in order of tying$\rightarrow$walking$\rightarrow$running$\rightarrow$tying, the sorting rate for motion states tying, sitting, walking, and running was 100% for each motion.

  • The aim of study intends to investigate effect of All-out condition on physical balance, agility and power and to provide the base data for the safety of firefighter. The results of the study are as follows. For power estimation, the sargent jump is $41.0{\pm}3.2cm$ before estimation and $42.2{\pm}6.02cm$ after estimation as All-out condition. For static balance estimation, the closed-eyes foot balance is $40.3{\pm}36.8$sec before estimation and $27.5{\pm}27.18$sec after estimation. For dynamic balance estimation, the beam walking is $6.2{\pm}1.22$sec before estimation and $6.4{\pm}1.57$sec after estimation. The results are statistically significant. For agility estimation, the side step is $40.3{\pm}3.40$rep/20sec before estimation and $43.3{\pm}2.50$rep/20sec after estimation. The results are statistically significant. The wholebody reaction time is $0.21{\pm}0.05$sec before estimation and $0.18{\pm}0.02$sec after estimation.
