“…The last two minutes of oxygen data for each trial were taken as the steady state and averaged at 10-second intervals for analysis. [21] The Borg scale is a 15-grade scale for rating perceived exertion that ranges from 6 (no exertion) to 20 (maximal exertion). It was applied at every two minutes of each walking trial in both groups.…”

Amaç: Bu çalışmada intermitan klodikasyon (İK) olan ve sağlıklı bireylerin tercih ettikleri yürüme hızı, yürüme oksijen maliyeti açısından görülen farklar ve aralarındaki ilişki araştırıldı ve İK anketi, klodikasyon ağrı skalası ve Borg skorları karşılaştırıldı. Ça lış ma pla nı: Çalışmamıza 12 sağlıklı birey (grup 1) ve İK'li periferik damar hastalığı (PDH) olan 12 hasta (grup 2) katıldı, bir sağlıklı birey ve üç İK'li hasta dış-lanma kriterleri nedeniyle çalışmadan çıkarıldı ve kalan 20 katılımcı değerlendirildi (grup 1 n=11, grup 2 n=9). Katılımcılar, indirekt kalorimetri yöntemi ile yürüme oksijen maliyeti ölçümü için önceden belirlenen hızlarda koşu bandında yürütüldü. İntermitan klodikasyon anketi test öncesi uygulandı. Bul gu lar: Grup 1'in ortalama yürüme hızı 77.8±11.4 m/dk., grup 2'nin 67.2±10.5 m/dk idi (p<0.05). Sağlıklı bireylerin ortalama yürüme oksijen maliyetleri 0.14±0.02 mL/kg/m, hasta grupta ise 0.18±0.04 mL/kg/m idi (p<0.05). Grup 2'de İK anket skoru ile oksijen maliyeti, tercih edilen yürüme hızı, klodikasyon ağrı skalası skoru ve Borg skoru arasında ilişki yoktu. Yürüme oksijen maliyeti ile maksimum yürüme mesafesi (MYM) arasında anlamlı ilişki vardı (p<0.05). Klodikasyon mesafesinin, Borg skoru ve klodikasyon ağrı skalası skoru ile anlamlı ilişkisi vardı. So nuç:Periferik damar hastalığı olan hastalarda, yürüme-nin metabolik etkinliği ve tercih edilen yürüme hızı azalabilir. Bu çalışma yürüme oksijen maliyetinin, tercih edilen yürüme hızının, Borg skorunun, klodikasyon mesafesinin ve MYM'nin, İK'li hastaların hareket kısıtlılığını izlemek için kullanılabilecek objektif parametreler olduğunu gös-termektedir.Anah tar söz cük ler: İntermitan klodikasyon; anketler; koşu bandı testi. Background:We aimed to determine the differences in the preferred walking speed, oxygen cost of walking and their correlations, comparing the intermittent claudication (IC) questionnaire, claudication pain scale and Borg scores in the patients with IC and the healthy subjects. Methods: Twelve healthy subjects (group 1) and 12 patients with IC (group 2) participated in our study, one healthy control subject and three patients with IC were excluded from the study because of exclusion criteria, and remain 20 participants were evaluated (n=11 in group 1, n=9 in group 2). The participants walked on a treadmill at pre-determined speeds for the measurements of oxygen cost of walking by indirect calorimetry method. The IC questionnaire was administered prior to the test. Results: The mean walking speed in group 1 was 77.8±11.4 m/min and 67.2±10.5 m/min in group 2 (p<0.05). The mean oxygen cost of the walking trial in healthy subjects was 0.14±0.02 mL/kg/m and 0.18±0.04 mL/kg/m in the patient group (p<0.05). In group 2, there was no correlation between the IC questionnaire score and oxygen cost, preferred walking speed, claudication pain scale score, and Borg score. The oxygen cost of walking was significantly correlated with the maximal walking distance (MWD) (p<0.05). There was a significant correlation between the initia...

“…Unfortunately, no research is available regarding to the energy expenditure of walking or economical walking speed among female athletes, but according to Dal et al (2010) that presents walking at a speed of 71.15 ± 13.85 m.min -1 (~2.7 mph) was the economical speed for both genders, it seems that female athlete walked more efficiently at that speed. Even though female athlete participants in this study expended higher energy at the speed of 3.5mph, they particularly expended less energy during walking at the speed of 3.0mph compared with the energy cost of walking for similar speeds reported in other studies (Thomas et al, 2009;Minetti et al, 2001).…”

“…As long as people naturally walk in the manner that conserves energy at speed of 1.2 to 1.5 m.s -1 (Dal et al 2010;Alexander, 2002), it can be promising to find if there is any significant difference in energy cost of walking for athletes and non-athletes, as active and non-active people respectively. In particular, there is no study reported to investigate the energy expenditure of walking among athletes and non-athletes.…”

This study aimed to determine, if there is a difference in energy expenditure during walking among athletes and non-athletes at two different speeds of walking. Ninety five healthy female students (47 athletes and 48 non-athletes) with a mean age of 22.4 (±1.6) years purposively participated in this study. Medical and sport participation history of the subjects was acquired through a questionnaire. Two experimental tests including anthropometric measurements,V O , and walking tests on treadmill at speeds of 3.00 and 3.5 mph were conducted. Results showed no difference in weight, height, body mass index, and leg length between both groups. The non-athletes expended a greater amount of energy than athletes (3.78±.1 and 2.95±.6 kcal.min -1 , respectively) at both speeds of 3.00mph and 3.5mph (4.89±1 and 3.94±.7 kcal.min -1 ). Based on energy requirements for walking at similar weights and speeds by ACSM's guideline, the female athletes walked at a slow, moderate and brisk pace. Most of the female non-athletes walked at a moderate, brisk and very brisk pace. This study revealed that regular exercise could improve walking efficiency, and the energy expenditure of walking would play an important role in the information processing for total energy requirement that progressively affects weight management and health.

ÖZAmaç: Bu çalışmada, kol salınımı kısıtlanmasının tercih edilen yürüme hızı, yürüme sırasında harcanan oksijen miktarı ve vücut kütle merkezi dikey yer değişimi üzerine etkileri araştırıldı. Gereç ve yöntemler:Çalışmaya Şubat 2011 -Nisan 2011 tarihleri arasında yaşları 18-30 yıl arasında değişen 52 sağlıklı erkek gönüllü katıldı ve beş farklı yürüme modeli kullanıldı. Her yürüme modeli için bireylerin zeminde tercih edilen yürüme hızları belirlendi. Bireyler bu hız ile koşu bandında yedi dakika yürütülerek oksijen tüketimleri kaydedildi. Birinci sakral vertebraya işaretleyici yerleştirildi ve iki kızıl ötesi kamera ile yürüme sırasında vücut kütle merkezi dikey yer değişimini belirlemek için kayıt yapıldı. Sonuç: Kol salınımının dengeyi sağlamada yardımcı olduğu, ancak, her iki kol salınımının kısıtlandığı durumlarda biyomekanik sistemlerin bu değişikliği kompanse edemediği için vücut kütle merkezi dikey yer değişimini ve yürümenin oksijen maliyetini artırdığı kanısındayız. Denge sorunu yaşayan bireylerde günlük kazaların önlemesi konusunda bulgularımızın yardımcı olabileceğini düşünmekteyiz.Anahtar sözcükler: Denge; yürüme; oksijen tüketimi; hız; üst ekstremite. ABSTRACTObjectives: This study aims to investigate the effects of arm swing restrain on preferred walking speed, amount of oxygen spent during walking and vertical displacement of the center of mass. Materials and methods:Between February 2011 and April 2011, a total of 52 healthy male volunteers, in the age range of 18 to 30, participated in the study and five different walking models were used. Individuals' preferred walking speeds on the ground were determined for each model. Their oxygen expenditures were recorded while individuals walked on the treadmill at this speed for seven minutes. We placed a marker on the first sacral vertebrae and used two infrared cameras to determine the changes in vertical displacement of the center of mass during walking. Results:We found a significant difference (F(3.734, 204) = 5.606, p<0.05) between normal (0.158±0.021 mL/kg/m) and at side restraint (0.166±022 mL/kg/m) and at front restraint (0.166±023 mL/kg/m) models in oxygen cost. We also found a significant difference (F(3.461, 204) = 5.144, p<0.05) between normal (3.81±0.94 cm) and at side restraint (4.36±1.05 cm) and at front restraint (4.25±0.93 cm) models in terms of vertical displacement of the center of mass. Preferred walking speed in the normal model (5.06±0.62 km/hr) was significantly higher (F(3.387, 204) = 10.433, p<0.05) than other models (at right restraint; 4.93±0.65 km/hr, at left restraint; 4.92±0.62 km/hr, at side restraint; 4.88±0.61 km/hr, and at front restraint; 4.88±0.56 km/hr). Conclusion:We are of the opinion that arm swing helps providing balance but in the situation of both arm restrain, since biomechanical systems cannot compensate this modification,...
