background: the aim of this study was to investigate muscle damage indicators and electromyography activities of quadriceps muscles at 25° of hip flexion in untrained healthy females after an eccentric exercise induced muscle fiber damage.   methods : a total of 14 healthy females participated in this pre-experimental study. the subjects performed maximal eccentric quadriceps contractions at 25...

Let G be a strongly connected digraph, and dG(vi,vj) denote the distance from vertex vi to vj defined as length of shortest directed path in G. The sum between vertices is sdG(vi,vj)=dG(vi,vj)+dG(vj,vi). matrix n×n SD(G)=(sdG(vi,vj))vi,vj∈V(G). For vi∈V(G), transmission G, denoted by STG(vi) or STi, row SD(G) corresponding vi. ST(G)=diag(ST1,ST2,…,STn) diagonal with transmissions zeroes elsewhe...

This study compares the changes in pathway and center of gravity (COG) on the calcaneus of non-involved and involved sides according to eccentric and concentric strengthening in patients with unilateral Achilles tendinopathy. The goal was to define the biomechanical changes according to eccentric strengthening for the development of clinical guidelines. Eighteen patients with Achilles tendinopa...

introduction: strength training has an important role in the exercise programs of normal individuals and athletes and it also has numerous benefits on the health of human body and spirit. one of the types of these exercise is eccentric resistance exercise which is associated with negative physiological changes. thus: this study examined the effects of a single bout of eccentric resistance exerc...

The forgotten topological index of a graph G is defined as the sum cube degrees its vertices. In this paper we establish eccentric complement line graphs and it denoted by . These are (v).e(v), where (edge vertex degree) some upper lower bounds for them.

The Pure Distance Law predicts grouping by proximity in dot lattices that can be organised in four ways by grouping dots along parallel lines. It specifies a quantitative relationship between the relative probability of perceiving an organisation and the relative distance between the grouped dots. The current study was set up to investigate whether this principle holds both for centrally and fo...

The role of mesons, particularly the pion, in the structure of nucleons is reviewed and investigated. Since quark-antiquark pairs are likely to " transform " into mesons at large distances, mesons are expected to contribute to nucleon structure. Their effects on the Gottfried sum rule, on the strangeness content of the nucleon, and on the spin of the nucleon are discussed.

The consensus string problem is finding a representative string (consensus) of a given set S of strings. In this paper we deal with the consensus string problems optimizing both distance sum and radius, where the distance sum is the sum of (Hamming) distances from the strings in S to the consensus and the radius is the longest (Hamming) distance from the strings in S to the consensus. Although ...
