The aim of this study was to characterize the backstroke swimming technique of 11-13 year-old swimmers when performing at very high intensity. A sample of 114 swimmers was divided into four groups regarding maturational and gender effect, who performed 25- m backstroke swimming at 50-m pace. Using two underwater cameras the general biomechanical parameters (speed, stroke rate, stroke length and...

We have isolated and sequenced a full-length cDNA clone encoding the 78,000 Mr intermediate chain (IC78) of the Chlamydomonas outer arm dynein. This protein previously was shown to be located at the base of the solubilized dynein particle and to interact with alpha tubulin in situ, suggesting that it may be involved in binding the outer arm to the doublet microtubule. The sequence predicts a po...

OBJECTIVES This study sought to assess the impact of intravascular ultrasound (IVUS) guidance on clinical outcomes following drug-eluting stent implantation when treating long lesions. BACKGROUND The role of IVUS guidance when treating long lesions has been tested during bare-metal stent, but not during drug-eluting stent, implantation. METHODS A total of 543 patients treated with stents ≥ ...

Background. Accuracy in archery is the ability to achieve (point) against target or Target Face when arrows are out of bow using a high level consentration carrying series shooting techniques. Based on many numbers arrow athletes who won championship by balancing their body balance and maintaining stamina.Purpose. To understand possibility any potencies some overviews sleeve length, arm muscle ...

AIM To study the relationship between age-related maculopathy (ARM) and exposure to sunlight using an objective method. METHODS In a case-control study of Japanese men aged > or = 50 years (67 controls without ophthalmic disease and 148 with ARM), those with ARM were separated into groups of early (n = 75) and late (n = 73) ARM. Facial wrinkle length and area of hyperpigmentation, which are c...

Background: When actual measurement of stature cannot be done, other surrogate parameters can be used to predict stature. Stature in clinical medicine and in the field of scientific research can be easily estimated using various anthropometric parameters like arm span, knee height, foot length and breadth etc. Arm span has been proven to be one of the most reliable predictors. Thus this study w...

Maximum Speed is mainly depends on stride frequency, length, lower limb arm leg build of the body, explosive strength etc. The main aim present study was to find out effects length and maximum speed. Fifteen college girls 19 25 years age were considered as subjects. speed performance measured through standard process. It observed from that highly negatively significantly correlated with frequen...

In this study, the force-length characteristics of the in vivo medial (GM) and lateral (GL) heads of the human gastrocnemius muscle were estimated from measurements in eight healthy male subjects. This involved: 1) dynamometry-based measurements of the moment generated during maximal isometric plantar flexion; 2) ultrasound-based measurements of fascicular length and pennation angle; and 3) ult...

BACKGROUND The deltoid muscle (DM) plays an essential role in retaining the stability and correct function of the upper limb. The aims of the study were to perform a detailed morphological analysis of the DM including its innervation, structure, attachments and relationship with adjacent structures. MATERIALS AND METHODS The study was carried out on 17 formalin-fixed cadavericupper limbs. Aft...
