Abstract
We evaluated whole body reaction time and one leg with eye closed balance in elderly Japanese. A total of 2059 elderly Japanese (730 men and 1329 women), aged 60 - 79 years, were enrolled in the cross-sectional investigation study. Anthropometric parameters, whole body reaction time and one leg with eye closed balance were measured. Whole body reaction time was significantly higher and one leg with eye closed balance was significantly lower in 70’s than those in 60’s in both sexes. Two hundred twenty seven men (31.1%) and 533 women (40.1%) were having no medications. In men, whole body reaction time was significantly higher and one leg with eye closed balance was significantly lower in subjects with medications than those in subjects without in 60’s. However, significant differences of whole body reaction time and one leg with eye closed balance between subjects with and without medications in men with 70’s and women with 60’s and 70’s were not noted. This standard mean value may provide a useful reference database for evaluating whole body reaction time and one leg with eye closed balance in Japanese elderly subjects.
Highlights
Rate of elderly subjects in Japan are dramatically increased and has become public health challenge in Japan
We evaluated whole body reaction time and one leg with eye closed balance in elderly Japanese
For preventing life-style related diseases, the level of maximal oxygen uptake and muscle strength was recommended in exercise and physical activity reference quantity for health promotion 2006 (EPARQ2006) by ministry of health, labor and welfare of Japan
Summary
Rate of elderly subjects (over 65 years) in Japan are dramatically increased and has become public health challenge in Japan. Lower and declining muscle strength was associated with increased mortality, independent of physical activity and muscle mass [5]. In elderly subjects without medications, this standard mean value in 60’s and 70’s may provide a useful database for evaluating anthropometric parameters and physical fitness [6]. According to other physical fitness i.e. agility and balance, there are few studies that focused on reductions in mortality or the prevention of lifestyle-related diseases, and the optimal level was not defined. Evaluation of agility i.e. whole body reaction time and balance i.e. one leg with eye closed balance still remains to be investigated in elderly Japanese without medications. We evaluated whole body reaction time and one leg with eye closed balance in elderly Japanese and compared those parameters between subjects with and without medications
