The aim of this study was to investigate the effect of low-intensity exercise training using belt electrode skeletal muscle electrical stimulation on muscle strength and cardiorespiratory fitness in healthy subjects. Nineteen healthy subjects were allocated into control or intervention groups; in both groups the participants kept regular physical activity while the intervention group underwent 30 min B-SES training at 3–4 METs for four weeks. Knee extensor muscle strength and cardiorespiratory endurance during incremental exercise test were measured at baseline and after four weeks for all participants. The relative change of knee extensor muscle strength in the intervention group was significantly higher than control group (p?p?相似文献   

Response of brain-derived neurotrophic factor to combining cognitive and physical exercise

Purpose: Brain-derived neurotrophic factor (BDNF) is well known for its potential to promote brain plasticity. It has been proposed that combining cognitive and physical exercise (CCPE) may have the potential to generate more synergistic benefits in cognitive function than either cognitive exercise (CE) or physical exercise (PE) alone. The purpose of this study was to examine acute responses of peripheral BDNF levels and cognitive performance to CE, PE, and CCPE.

Methods: Thirteen healthy adult men participated in four experimental sessions; a 30-min CE, a 30-min cycling PE at an intensity of 60% peak oxygen uptake, a 30-min CCPE at the same intensity as PE, and a 30-min session of complete rest. Plasma BDNF levels and cognitive performance were measured before and after each session.

Results: Both PE and CCPE significantly increased plasma BDNF levels (p?p?≥?.05), and there was no significant difference in peripheral BDNF levels between PE and CCPE (p?≥?.05). No session induced a significant change in cognitive performance (p?≥?.05).

Conclusions: Our study suggests that CE and PE have different responses of peripheral BDNF levels and that CCPE had no additional or synergistic effect on peripheral BDNF levels compared with PE alone. This study offers further insights into the potential mechanisms underlying the respective roles of CE, PE, and CCPE for peripheral BDNF levels and cognitive performance.  相似文献   

Higher reliability and closer relationship between open-field test measures on aggregation data     

Toshiaki Tachibana 《Learning & behavior》1985,13(4):345-348

Eighty male rats were tested in an open field. Correlation coefficients between aggregated test days were larger than those between nonaggregated test days, indicating that aggregation across days can enhance the reliability of scores in the open-field test. Also, absolute values of correlation coefficients among the seven open-field test measures based on the aggregated data were generally larger than those based on nonaggregated data, indicating that the correlation among measures may be closer than previously assumed on the basis of nonaggregated data. Issues concerning appropriate aggregation and limitations of aggregation are discussed. The technique of aggregation is recommended as a routine procedure in the analysis of open-field test results, because of the enhanced reliability obtained.  相似文献   

Job search motivation of part-time or unemployed Japanese college graduates

We clarify how individuals actively interact with socio-cultural contexts to attain regular employment in Japan. Based on a large sample (N = 3,512) of part-time employed and unemployed college graduates (23–39 years old), we found that: Career decision making self-efficacy predicted job search; a lack of both hope and fulfillment motivated job search, while having hope promoted it; wishing for perfect vocation and being free from both inclination towards personal interests and passivity motivated job search. Clients’ desire for “a perfect vocation,” should not necessarily be considered as a career barrier but, perhaps, rather as an asset for motivating job search. Counselors should seek to better understand the influence of clients’ socio-cultural contexts on their career attitudes.  相似文献   

The open-field test: An approach from multivariate analysis     

Toshiaki Tachibana 《Learning & behavior》1980,8(3):465-467

The validity of open-field test measures was assessed by simple and multiple regression analysis, taking the difference in experience of a novel situation as the external criterion. Ambulation in the first 1 min, rearing, latency to urination, and urination score were valid indexes of a new operational concept presented in this study, and they were also reliable. The weighting coefficients were obtained for the reduction of multiple measure scores to a single score that represents the concept.  相似文献
