One of the ways of the growth and development of each society is to provide an appropriate context and create equal opportunities for different sectors in access to urban amenities. With the arrival of the aging period, there are significant changes in the physiological and psychosocial characteristics of humans. These changes force elderly people to understand the physical environment differently from the younger ones and respond differently. Elderly people have a lot of leisure time due to their age and reduced activity, and their use of urban spaces is more than other segments of society. With increasing numbers of elderly people, international organizations have called for special attention to this age group. Thus, many physical means, with the help of advanced day-to-day knowledge, and psychologically, should be provided by establishing social and family relationships that are appropriate for the elderly. This research has been carried out in order to achieve and introduce indicators and standards for environmental suitability and improvement of urban spaces.
The method of research is based on library and field studies to identify, collect and study various sources of open and urban spaces and physical and mental conditions of the elderly. Examining barriers and constraints Helps to designers, planners and city managers in search of factors for creating and solving such problems in future plans.

Optimal performance of paddlers depends on the combination of anthropometrical, physiological, biomechanical and psychological factors.

The aim of this study was to investigate the relationship between physiological characteristics and performance of the Iranian Female National Kayak Paddlers’ Team.

In this study, all members of the Iranian women's national kayak team (aged 16.8 ± 2.4 yr., height 171.6 ± 3.5 cm, body mass 62.73 ± 5.51 kg, fat mass 17.05 ± 3.76 % and body mass index 21.34 ± 09 kg/m2) were examined and recruited as subjects. Physiological characteristics included maximal aerobic power, lactate threshold, maximal heart rate, anaerobic peak power, anaerobic mean power, fatigue index and performance index was 500m paddler in flat water. The normality of distribution of the variables was analyzed by Kolmogorov-Smirnov test. To determine the relationship between physiological characteristics and exercise performance was used Pearson’s Correlation of Coefficient Test.

The results showed that between 500m performance of Iranian Female National Kayak Paddlers’ Team and absolute anaerobic peak power (r= -0.72; P= 0.02), absolute anaerobicmean power (r= -0.72; P= 0.02), and relative anaerobic mean power (r= -0.66; P= 0.04) there was statistical significant relation.

Therefore, according to the results of this study we can suggested that kayak paddlers not only need a high body dimensions but the anaerobic system contribution is also veryimportant for successful exercise performance.

Creatine and Glutamine are supplements that involve in protein metabolism. The present study examined the effects of creatine and creatine-glutamine supplementation on the physiological and anthropometric characteristics of the elite wrestlers. For this reason, 36 wrestlers volunteered in Mazandaran province. They were divided in three homogeneous groups including creatine group as the experiment group 1 (n=12), creatine-glutamine group as the experiment group 2 (n=12) and placebo group as the control group (n=12). In a pretest-posttest design,  strength, peak power, average power, total work performed) were measured. For data analysis, Kolmogorov- Smirnov test, Repeated Measure and one-way ANOVA were used (p<0.05) to measure examine the distribution of normalized samples and compare the mean difference between groups respectively used. The Results showed that there were not significant differences in weight, BMI, body fat percentage, peak power, average power and total work performed between both experiment groups and control group. But There was a significant difference in maximal strength between both experimental groups and control group (p=0.040) but it was not significant difference between the experiment groups (p=0.60). It was concluded that creatine supplement and creatineglutamine supplement influences maximal strength and it is suggested to be used by the athletes.
