Bu çalışmanın amacı, serbest ağırlık ve Smith makine barbell bench press egzersizindeki doğrudan ölçülen bir tekrarlı maksimum (1TM) ile yük-hız ilişkisinden elde edilen 1TM minimal hız eşiği (1TMMHE) sıfır hızdaki yük (1 TMSHY) tahmin yöntemleri arasındaki ilişkileri farklılıkları belirlemektir. Çalışmaya, en az 5 yıl direnç antrenmanı geçmişine sahip rekreasyonel amaçlı vücut geliştirme branş...

We present for the first time a study of peculiar giant radio galaxy (GRG) J223301+131502 using deep multi-frequency observations from GMRT (323, 612, and 1300 MHz) LOFAR (144 along with optical spectroscopic WHT~4.2m telescope. Our have firmly established its redshift 0.09956 unveiled exceptional jet structure extending more than $\sim$ 200 kpc leading to kink 100 kpc. measure overall size thi...

Megakaryocytes generate platelets by remodeling their cytoplasm first into proplatelets and then into preplatelets, which undergo fission to generate platelets. Although the functions of microtubules and actin during platelet biogenesis have been defined, the role of the spectrin cytoskeleton is unknown. We investigated the function of the spectrin-based membrane skeleton in proplatelet and pla...

CONTEXT Various studies report decreased muscle activation in the concavity of the curve in patients with scoliosis. Such decreased muscle-performance capacity could lead to sustained postural deficits. OBJECTIVE To investigate whether specific asymmetrical sports therapy exercises rather than symmetrical back strengthening can increase EMG amplitudes of paraspinal muscles in the concavity of...

Platelet (PLT) production represents the final stage of megakaryocyte (MK) development. During differentiation, bone marrow MKs extend and release long, branched proPLTs into sinusoidal blood vessels, which undergo repeated abscissions to yield circulating PLTs. Circular-prePLTs are dynamic intermediate structures in this sequence that have the capacity to reversibly convert into barbell-proPLT...

For achieving accurate and safe measurements of the force and power exerted on a load during resistance exercise, the Smith machine has been used instead of free weights. However, because some Smith machines possess counterweights, the equation for the calculation of force and power in this system should be different from the one used for free weights. The purpose of this investigation was to c...

Recent studies indicate that the utilization of the hexagonal barbell jump squat (HBJS) compared with the traditional barbell jump squat may offer a superior method of developing peak power. The notion that a single optimal load may be prescribed in training programs aiming to develop peak power is subject to debate. The purpose of this study was to identify the optimal load corresponding with ...

The aim of this study was to examine the effect of fatigue during one set of 6-RM bench pressing upon the muscle patterning and performance. Fourteen resistance-trained males (age 22.5±2.0 years, stature 1.82±0.07 m, body mass 82.0±7.8 kg) conducted a 6-RM bench press protocol. Barbell kinematics and EMG activity of pectoralis major, deltoid anterior, biceps brachii, triceps brachii, rectus abd...
