Shaping Bodies Shaping Minds: Selim Sırrı Tarcan and the Origins of Modern Physical Education in Turkey

This article discusses the role of Selim S?rr? Tarcan in the emergence of physical education in Turkey, which was an important component of the modernisation project of the Republic. Selim S?rr? Tarcan was a devoted moderniser who contributed to this process with his works and ideas in the field of physical education, a political project for the creation of strong and healthy citizens of the newly established nation-state. To analyse his contribution, we first establish the longer historical context that allows us to understand the development of modern education as a tool for shaping young generations. Second, we will focus on portions of Selim S?rr? Tarcan's biography for understanding the emergence of modern physical education and conclude by analysing his contributions to develop the archetype of healthy young citizens through modern physical education.     

Effects of load on ground reaction force and lower limb kinematics during concentric squats

The purpose of this study was to examine the effects of external load on vertical ground reaction force, and linear and angular kinematics, during squats. Eight males aged 22.1?±?0.8 years performed maximal concentric squats using loads ranging from 7 to 70% of one-repetition maximum on a force plate while linear barbell velocity and the angular kinematics of the hip, knee and ankle were recorded. Maximum, average and angle-specific values were recorded. The ground reaction force ranged from 1.67?±?0.20 to 3.21?±?0.29 times body weight and increased significantly as external load increased (P?<?0.05). Bar linear velocity ranged from 0.54?±?0.11 to 2.50?±?0.50?m?·?s^?1 and decreased significantly with increasing external load (P?<?0.05). Hip, knee and ankle angles at maximum ground reaction force were affected by external load (P?<?0.05). The force?–?barbell velocity curves were fitted using linear models with coefficients (r ²) ranging from 0.59 to 0.96. The results suggest that maximal force exertion during squat exercises is not achieved at the same position of the lower body as external load is increased. In contrast, joint velocity coordination does not change as load is increased. The force?–?velocity relationship was linear and independent from the set of data used for its determination.

An investigation of the accuracy and reliability of body composition assessed with a handheld electrical impedance myography device

The purpose of this study was to compare the body fat per cent (BF%) assessed with a unique handheld electrical impedance myography (EIM) device, along with other popular methods, to dual-energy X-ray absorptiometry (DXA). Participants included 33 males (aged 24.3?±?4.6 years) and 38 females (aged 25.3?±?8.9 years) who completed 2 visits separated by 24–72?h. The assessments included DXA, bioelectrical impedance analysis (BIA), skinfold measures (SKF), and three separate EIM measurements. No significant differences in BF% (P?>?0.05) were found between all EIM assessments when compared against DXA for both males and females for each visit. All methods showed no significant differences in BF% (P?>?0.05) between days within themselves. Across both days, the standard error of the estimate (SEE) for the EIM measurements ranged from 2.66% to 3.15%, the SEE for BIA was 2.80 and 2.85, and for SKF was 2.90 and 2.82. The 95% limits of agreement ranged from ±5.34% to ±6.38% for EIM measurements and were highest for SKF (±7.42% and ±7.47%). The total error for both days was largest for SKF (5.20% and 5.35%) and lowest for the EIM measurements (2.48–3.24%). This investigation supports use of a handheld EIM device as an accurate and reliable method of estimating BF% compared to DXA in young, apparently healthy individuals with BF% in the range of 10–22% for males and 20–32% in females and suggests this EIM device be considered a viable alternative to other established field measurements in this population.     

乳酸能系统在100m跑中的代谢特征研究

通过对30名不同水平的体育系学生100m跑和不同段落重复跑后的血乳酸测定，发现不同水平受试100m跑后都存在着不同程度的血乳酸堆积，且受试的训练水平对血乳酸值有显影响。不同段落重复跑后的血乳酸值在随跑距延长而逐渐升高的过程中，存在着一个急剧升高的阶段，因此，乳酸能系统在100m跑中发挥着重要的作用。
