[Purpose] The purpose of the present study is to examine the effects of abductor hallucis and gluteus maximus strengthening exercises on pronated feet. [Subjects and Methods] The present study was conducted with 18 adults without no history of surgery on the foot or ankle. One group performed both gluteus maximus strengthening exercises and abductor hallucis strengthening exercises, while the other group performed only abductor hallucis strengthening exercises five times per week for four weeks. [Results] The group that performed both gluteus maximus and abductor hallucis strengthening exercises showed smaller values in the height of navicular drop than the group that performed only abductor hallucis strengthening exercises. The muscle activity of the gluteus maximus and the vastus medialis increased during heel-strike in the group that added gluteus maximus exercises, and the muscle activity of the abductor hallucis significantly increased in both groups. [Conclusion] Given the results of the present study, it can be suggested that strengthening the gluteus maximus while also performing exercises to correct the pronated foot is an effective method for achieving normal gait.

Background: There are few data on the interaction between temperature and snow and rain precipitation, although they could interact in their effects on road traffic injuries.Methods: The integrated database of the Korea Road Traffic Authority was used to calculate the daily frequency of road traffic injuries in Seoul. Weather data included rain and snow precipitation, temperature, pressure, and fog from May 2007 to December 2011. Precipitation of rain and snow were divided into nine and six temperature range categories, respectively. The interactive effects of temperature and rain and snow precipitation on road traffic injuries were analyzed using a generalized additive model with a Poisson distribution.Results: The risk of road traffic injuries during snow increased when the temperature was below freezing. Road traffic injuries increased by 6.6% when it was snowing and above 0°C, whereas they increased by 15% when it was snowing and at or below 0°C. In terms of heavy rain precipitation, moderate temperatures were related to an increased prevalence of injuries. When the temperature was 0–20°C, we found a 12% increase in road traffic injuries, whereas it increased by 8.5% and 6.8% when it was <0°C and >20°C, respectively. The interactive effect was consistent across the traffic accident subtypes.Conclusions: The effect of adverse weather conditions on road traffic injuries differed depending on the temperature. More road traffic injuries were related to rain precipitation when the temperature was moderate and to snow when it was below freezing.

It is currently accepted that the consumption of fruit-derived antioxidants such as vitamin C, carotenoids, and flavonoids provides a preventive effect against cardiovascular disease. The purpose of the present study was to investigate potential cardiovascular protective properties of aqueous and 70% ethanol extracts from kiwifruit by analyzing the antioxidative, antihypertensive, hypocholesterolemic, and fibrinolytic activities in vitro. Aqueous and 70% ethanol extracts at 50 mg/ml showed DPPH-radical scavenging activities of 72.31% and 70.75%, respectively. Total antioxidant activity in linoleic acid emulsion was 85—88% at 10 mg/ml and 96—98% at 50 mg/ml of kiwifruit extract. Inhibitory activities against angiogensin I-converting enzyme of kiwifruit extracts were 21—26% at 10 mg/ml and 46—49% at 50 mg/ml, and inhibitory activities on HMG-CoA reductase were 13—14% at 10 mg/ml and 19—30% at 50 mg/ml. Fibrinolytic activity of kiwifruit was also observed at a high concentration of 100 mg/ml in both aqueous and 70% EtOH extracts. Based on our results, kiwifruit have potential cardiovascular protective properties in vitro.
