The aim of this study was to investigate the effect of a sort-term walking exercise on some lung function parameters (such as forced vital capacity (FVC) and maximal voluntary ventilation (MVV)) in obese children. Total of 23 subjects who have BMI (body mass index) > 25 kg/m2 and age ranged from 12 to 14 years participated in this study. Subjects were randomly divided into two groups as intervention (n = 12) and control group (n = 11). Anthropometric features of subjects were shown in Table 1. For this study, lung function parameters were measured by using a spirometer. In this research, throughout 6 weeks, participants followed a closely supervised walking program consisted of 45-min sessions five times in each week with an intensity of 60% of heart rate reserve. SPSS was used for statistical analyses (SPSS Inc., Chicago, IL). T tests were utilised to compare before and after the changes between groups. Table 2 shows that there were significant increases in FVC and maximum MVV (p < 0.05) in intervention group. Although before the study the mean baseline FVC was 2.99 ± 0, 50 litres (L), this value changed to 3,09 ± 0,51(L) after the 6-week walking period. Further, MVV values of post-training period were significantly higher than that of pre-training period (111.73 ± 21.99 vs. 115.21 ± 18.99; Pre-training vs. Post-training. p < 0.05). Control group had no significant change in all outcomes from pretest to posttest (p > 0.05). All in all, short-term walking program had a significant positive effect on FVC and MVV lung functions. This research was designed to specify the effect of walking on respiratory system. The result of this study indicated that a short-term moderate intensity walking exercise may enhance changes in obese children’s respiratory system.

Impact of Social-Ecologic Intervention on Physical Activity Knowledge and Behaviors of Rural Students CENGİZ, CEVDET; İnce, Mustafa Levent (Human Kinetics, 2014-11-01) Background: The purpose of the study was to determine the effects of a social-ecologic intervention on health-related fitness (HRF) knowledge and behaviors of students (n = 62) living in rural areas. Methods: A prepost test control group design was constructed. In addition, qualitative data were collected by focus group discussions in the experimental group. Physical activity environment of a middle school was changed based on the social-ecologic model (SEM) with a focus on intrapersonal, interpersonal, com...
A Multivariate Approach to Assessing Anaerobic Power Following a Plyometric Training Program Koçak, Mehmet Settar (Ovid Technologies (Wolters Kluwer Health), 1997-01-01) This study used a multivariate approach to assess anaerobic power in 20 athletes and 20 nonathletes undergoing 6 weeks of plyometric training, and 20 controls. A 3 x 2 mixed model MANOVA was done to analyze the pre-and posttest scores of vertical jump, 50-m dash, and Margaria-Kalamen stairclimbing test. The Group x Test interaction was significant (p < 0.001). Both groups that underwent plyometric training improved significantly (p < 0.01) on all tests of anaerobic power. Of the dependent measures, the Marg...
Master Plans for Pedestrian and Bicycle Transportation: Community Characteristics Severcan, Yücel Can; Levinger, David; Perry, Cynthia; Carter, Louise; Eyler, Amy; Aytur, Semra; Cradock, Angie L. I.; Evenson, Kelly R.; Heinrich, Katie; Kerr, Jacqueline; Litt, Jill; Severcan, Yucel; Voorhees, Carolyn (Human Kinetics, 2010-03-01) Background: Recent research demonstrates the importance of targeting the built environment to support individual physical activity, particularly for people experiencing health disparities. Master plans to promote biking and/or pedestrians (BPMPs) are a potential method for environmental change. This descriptive study aims to provide a snapshot of plan attributes and better understand demographic, social and transportation characteristics of communities with BPMPs. Methods: We collected a census sample of BP...
Effects of eccentric hamstring strength training on lower extremity strength of 10-12 year old male basketball players Tansel, Rıfat Baran; SALCI, YAŞAR; Yıldırım, Ahmet; Koçak, Mehmet Settar; Korkusuz, Feza (IOS Press, 2008-01-01) Objective: To investigate the effects of eccentric hamstring training on strength measures and vertical jumping performance.
Evaluation of body composition using three different methods compared to dual-energy X-ray absorptiometry Duz, Serkan; Koçak, Mehmet Settar; Korkusuz, Feza (Informa UK Limited, 2009-01-01) In this study, we compared the simple methods of skinfolds, ultrasound, and bioelectrical impedance analysis (BIA) against the standard of dual-energy X-ray absorptiometry (DEXA) in the assessment of body fat in normoactive Turkish male and female university students. We wished to develop new regression equations to more accurately predict percent body fat from skinfolds and ultrasound for this group of individuals. One hundred and four male (age 22.22.5 years; height 1.770.06 m; mass 74.910.4 kg) and one h...
