In this review we summarized literatures about biomechanical researches in kayaking. Biomechanical methods provide data on a number of analytical techniques and kayak moving posture for coaches and athletes. 3-D kinematic analysis, on-water dynamic analysis and surface electromyography measurement are the most common methods through which we can assess and describe effects of paddling technique...

The present study examined the effect of the geometric parameters of the Rockfill dams on the 2D static analysis of slope stability. In this regard, several numerical models analyzed for eight heights, three slopes of upstream and downstream, three vertical and skewed core thicknesses and four different impounding time stages namely, "End of Construction", "Full Reservoir", "Half Full Reservoir...

The most commonly used method for training feature weights in statistical machine translation (SMT) systems is Och’s minimum error rate training (MERT) procedure. A well-known problemwith Och’s procedure is that it tends to be sensitive to small changes in the system, particularly when the number of features is large. In this paper, we quantify the stability of Och’s procedure by supplying diff...

OBJECTIVE To identify the effect of a novel augmented core stabilization exercise technique on physical function, pain and core stability in patients with chronic low back pain. DESIGN A block randomized controlled trial with two groups. SETTING A sports rehabilitation clinic. PARTICIPANTS Forty patients with low back pain (20 experimental, mean (SD) age 50.35 (9.26) years and 20 control,...

BACKGROUND Overhead athletes often suffer injury to the glenohumeral joint secondary to inherent instability. However, little is known about the relationship between core stability and shoulder dysfunction among athletes. PURPOSE The purpose of this study was to analyze the difference between healthy athletes and those with shoulder dysfunction in regard to core stability measures. Secondary ...

We describe an open-source implementation of the Margin Infused Relaxed Algorithm (MIRA) for statistical machine translation (SMT). The implementation is part of the Moses toolkit and can be used as an alternative to standard minimum error rate training (MERT). A description of the implementation and its usage on core feature sets as well as large, sparse feature sets is given and we report exp...

This article is intended to provide an understanding of the importance of core musculature to runners and to offer exercises that will help them achieve desired mobility, stability, muscular balance, and neuromuscular control. Please see Table 1 for an example of how to incorporate these exercises into a periodized training program. It is highly recommended, however, that athletes consult a ski...
