Background: Encouraging physical activity is an important public health priority worldwide due to its multiple health outcomes, impact on quality of life, and significant savings in hospitalization and healthcare costs among older adults. Recently, physical literacy, a concept to support participation and maintenance of physical activity in older adults, has been introduced.
Aims: The aim of the present study was to determine the validity and reliability of the Persian version of the Perceived Physical Literacy Scale for the elderly.
Methods: The present study was descriptive-correlational. For this purpose, 408 elderly men and women completed the Persian version of the Perceived Physical Literacy Scale for the Elderly. First, the accuracy of the translation of the Persian version of the questionnaire was confirmed using the back-translation method, and then confirmatory factor analysis based on structural equation modeling was used to determine the construct validity of the questionnaire, and Cronbach's alpha coefficient was used to determine internal consistency. Also, for the temporal reliability of the questions, intraclass correlation was used with the test-retest method.
Results: The results showed that the goodness of fit index and adaptive fit index were desirable. The temporal reliability and Cronbach's alpha coefficient for self-efficacy and its dimensions were higher than 0.7 .
Conclusion: Based on the results, the Persian version of the Perceived Physical Literacy Scale for the Elderly has acceptable construct validity and internal and temporal reliability, and it can be used as a valid and reliable tool for assessing the physical literacy of Iranian elderly people.

.Introduction: Exercise has a great effect on health promotion, and recently its effect on improving the nervous system functions and cognitive processes has attracted the attention of many researchers. This study aimed to investigate the effect of internal and external attention during futsal dribbling skill training on the serum level of glial cell-derived neurotrophic factor (GDNF) and cognitive function.Methods: forty-two untrained female students were selected by available sampling and randomly assigned into four Control without training, Control with training, Internal Attention, and External Attention groups. During 15 sessions, the participants of the training groups did the futsal dribbling training according to the dribbling test by making five trials in each session. Forty-eight hours before the pre-test and after the post-test, blood samples were drawn and cognitive function was measured using the Stroop test. GDNF blood factor was measured via the ELISA method. Statistical analysis was conducted at a significance level of P≤0.05.Results: Internal attention during dribbling training had no significant effect on GDNF serum level (P=0.12) and cognitive function (P=0.07). External attention during dribbling training had a significant effect on GDNF serum level (P=0.01) but did not have a significant effect on cognitive function (P=0.16).Conclusion: The type of internal or external attention during futsal dribbling does not make a particular difference in cognitive function and increases the serum level of GDNF. But the effects of external attention on the serum level of GDNF have been significant.
