Purpose The purpose of this study was to investigate the changes of gait patterns and muscle activations according to dual tasks during stair ascending. Methods Twelve sedentary young male adults(Age: 27.0±1.8 yrs, Weight: 65.8±9.9 kg) without any lower extremity injuries participated in the study. Participants performed stair walking up 7 floors and their ascending motion on each floor was analyzed according to dual tasks. A wireless electromyography (EMG) were attached on the Rectus Femoris(RF), Biceps Femoris(BF), Gastrocnemius(GN), Tibialis Anterior(TA) muscle to calculate integrated EMG(iEMG) and co-contraction index(CI). Chest and left heel accelerometer signal were recorded by wireless accelerometer and those were used to calculate approximate entropy(ApEn) for analyzing gait pattern. All analyses were performed with SPSS 21.0 and for repeated measured ANOVA and Post-hoc was LSD. Results The results of this study indicated that dual task appeared to increase their time, CI and there were a statistically significant difference in most muscle on each floors compared to the non dual tasks. Also, ApEn were a statistically significant difference in only left and right direction than non dual task. Subjects showed more irregular pattern and instability muscle activation response during dual tasks. Conclusion Because there are many dangers often use of stairs in everyday life, in the future, we have to make a lot of efforts to prevent fall.

The recent increases in international efforts for designing and implementing initiatives and programs about 'development though sport' have accompanied the remarkable growth of the 'sport for development and peace'(SDP) sector. This global prevalence of SDP and the resulting augmentation of its social significance have rendered a growing scholarly attention to SDP in the sociology of sport. Moreover, a grounding rationale for SDP initiatives to enhance positive individual and social changes through sport has also offered an interesting research area for the sociology of sport. This paper aims to review sport sociology literature about SDP. Major findings include a set of descriptive reports about the institutionalization of SDP and critical/reflective approaches to SDP's outcomes and limitations. It is noted that the institutionalization of SDP consists of ideological and policy endeavors, SDP organizations and institutions, and classifications of SDP project types. Despite of positive outcomes resulted from SDP programs, it has been highlighted that the ongoing issues and limitations of SDP include ambiguities of development concept, the Global North hegemony, unilateral top-down program management, and the inherent complexity and lack of program monitoring/evaluation.
In sport context, the motivational climate created by significant others (e.g., coachs and peers) has been influences on the athletic-student's motivation, engagement, performance, and skill development. Collective efficacy is important for team performance because it influences a group's task choice, effort expenditure, persistence in the face of failure, and resistance to discouragement. This study was to examine the influence of peer motivational climate (i.e., task-involving and ego-involving motivational climate) and coach autonomous support for basic psychological need satisfaction and collective efficacy. In the study, participants were 289 athletic-students' of team sports. In the study then, questionnaire was assessed using by the correlation and path analysis. The results showed that task-involving motivational climate significantly predicted of collective efficacy, while ego-involving motivational climate were negatively predict to the collective efficacy. The results suggest the importance of considering peer influence in addition to coach influence when examining motivational climate in team sport.
