This study investigated the relationship between the level of maximal oxygen uptake (VO2max) and the function of autonomic nervous system (ANS) in 30 young male adults. The function of ANS was measured by heart rate variability (HRV) and the post-exercise heart rate recovery (HRR). The results showed that there was a significant relationship between VO2max and HRV, but not between VO2max and HRR. Furthermore, the group of higher VO2max showed higher SDNN, RMSSD, TPlog, VLFlog, LFlog, HFlog level and lower physical stress index than those of the group of lower VO2max. In conclusion, there is a significant relationship between VO2max and the function of ANS measured by HRV in young male adults and it seems that the aerobic capacity measued by VO2max might affect HRV positively.

This study investigated the relationship between physical fitness(PF) and autonomic activity measured by heart rate variability in 46 women(30.8-58.4 years). PF included both of health and exercise function related ones. The results showed significantly positive correlation between muscular endurance(ME) and parasympathetic activity(RMSSD and logarithmic high frequency level(HFlog). Response time(RT) also showed significantly negative relationship with RMSSD, HFlog, and logarithmic total power. As a result of comparison of PF among 4 groups distributed by HFlog, the group with 50-75 percentile level of HFlog showed significantly superior ME and RT than 0-25 percentile group. In conclusion, ME and RT were related to parasympathetic activity in adult women and these PF factors are most superior in women with optimally not excessively activated parasympathetic system.

Objective: Lectins are cell-agglutinating and sugar specific proteins or glycoproteins of non-immune origin that precipitate glycoconjugates having saccharides of appropriate complementarity. Because of these properties, plant lectins have been used to help characterize the carbohydrate moieties of glycoproteins in the zona pellucida (ZP) of several mammalian species including pigs. Treatment of oocytes with various lectins blocks sperm binding to the ZP in various mammalian species. This study was undertaken to examine the distribution of sugar residues in the ZP of pig oocytes matured in vitro and the ability of spermatozoa to bind to ZP and in vitro penetration in oocytes treated with fluorescein isothiocyanate (FITC)-labelled lectins. Materials and Methods: The lectins of Banderiaea simplicifolia (BS-II, bind to $\beta$-D-N-acetylglucosamine), Canavalin ensiformis (Con A, bind to $\alpha$-D-Mannose), Lens culinaris (LCA, bind to a-D-Mannose), Ricinus communis (RCA-I, bind to $\beta$-D-Galactose) and Ulex europaeus (UEA-I, bind to $\alpha$-L-Fucose) were examined for spermatozoa penetration, binding capacity to ZP and distribution of lectins. Results: The penetration rates were significantry (p<0.05) higher in control oocytes (63%) than those treated with all lectins, but penetration rates ($40{\sim}49%$) were simililar in group treated with lectins. The incidence of monospermy was similar in oocytes untreated and UEA-I, but it was higher in oocytes treated with BS-II, Con A, RCA-I and LCA. The porcine oocytes cultured for 48 h in TC-199 medium were freed from cumulus cells and treated for 30 min with fluorescein isothiocyanate-labelled lectins. When examined under fluorescein illumination, higher (p<0.001) proportions of oocytes showed fluorescein of zona pellucida after treatment with Con A (93%), LCA (93%) and RCA-I (100%) than BS-II (37%) and UEA-I (50%). All of the oocytes treated with RCA-I exhibited strong fluorescein in the outer region of the zona pellucida while those treated with LCA exhibited strong fluorescein throughout the zona pellucida. BS-II bounded mainly to the outer region and UEA-I bounded mainly to the inner region of the zona pellucida, with either strong or weak fluorescein. At 120 min after insemination in vitro, fewer spermatozoa were bound to the zona pellucida of the oocytes treated with BS-II, Con-A and RCA-I. Of the lectins, Con A most inhibited sperm binding. Conclusions: These results suggest that $\beta$-D-Galactose residues in the porcine zona pellucida may act as primary sperm receptors and inducers of the sperm acrosome reaction and these sugar residues may be involved in the block to polyspermy.

The purpose of this study is to investigate the effect of yoga exercise program on fall-related physical fitness in elderly women. Subjects for study were 15 elderly women with an age range of 75 to 89 years. Balance(OLS, TUG), flexibility(hip joint ROM, ankle ROM), lower strength(knee extensor/flexor strength, CST were investigated before and mid(after 3 months) and after 9 months yoga exercise program(60min/day, 2 day/week, for 9 months). All data were analyzed by ANOVA with repeated measures of SPSS. The results showed that significant increase were found for OLS(p<.01, p<.001), hip joint(p<.001, p<.05), ankle ROM(p<.001, p<.01), knee extensor(p<.05, p<.001), knee flexor(p<.001, p<.001), CST(p<.001) after 9 months yoga training. But there was no significant difference after 3 months yoga training in all variables except CST. Therefore, we recommend that a yoga exercise program in elderly women is a useful intervention to falls-related physical fitness, but further long-term program is required.

This study investigated the effect of fear of falling(FOF) on physical activity(PA) pattern in Korean female older adults. The subjects were 94 Korean females aged 65-79. PA was measured by accelerometer and FOF by Korean Survey of Activities and Fear of Falling in the Elderly. Most of PA variables except time spent on low and vigorous PA showed significant correlation with FOF. However, there was significant difference between lower and higher FOF groups in only one PA variable, time spent on moderate PA(modPA), with subjects’ age defined as covariate. In this result, modPA of higher FOF group was lower than that of lower FOF group. A multiple regression analysis with the subjects’ age included as correction factor also showed that FOF significantly affect modPA. This study concludes that FOF influences moderate PA level negatively with no effects on light and vigorous PA in Korean female older adults.
