Ergometers have been developed as off-season or dryland training tools for sports such as rowing and cross-country skiing. These ergometers have recently been staples in the training methods for functional fitness athletes. Purpose: To examine the relationship between athlete strength and power with rowing ergometer and ski ergometer performance. Methods: Eight healthy college-aged participants, age 18-26 years volunteered to go through a series of strength and ergometric exercises while being assessed with a metabolic cart to measure gas exchange. The three strength measures were a maximal effort on bench press, back squat, and deadlift. A watt bike was also used to assess lower body power output. All strength tests were performed following the National Strength and Conditioning Association protocols. The ergometric performances on ski ergometer and rower were performed both using the Concept2 model with the damper settings at 10. Results: A significant relationship exists between strength and ergometer performance at both sprint and mid-distances. Conclusions: Athlete strength is a significant contributor to ski ergometer and rowing ergometer performance at 100-meter and 2000-meter performances. When considering training protocols for rowing and cross-country skiing, athletes and coaches should invest in addressing strength as a meaningful portion of the training effort.
Contribution/ Originality
The paper's primary contribution is finding the relationship athlete strength and power have with ergometer performance.

The aim of this study is to develop a scale that demonstrates the transfer score of a football player, with the help of metrics generated through network science. Six matches played Turkish National Football Team in the 2014 World Cup Qualifiers were analyzed with e-analysis soccer program. To obtain the network of the matches and the measurements of networks we used the open-source program Gephi. By taking into consideration the correlations between 11 network metrics, factor analysis was performed, and factor loadings were obtained. To determine the transfer score, as a measure of centralization: degree, weighted-degree and betweenness-centrality, and as a measure of contravention: eccentricity, 4 variables were defined. As a result of factor analysis, three variables were combined into a single component. The variance explanation value was found to be 90.611%, the internal consistency criterion was 0.66 and the transfer score value was calculated using the squares of factor loadings. The scale we developed will be able to determine the transfer value of a player, as well as the changes in the player's performance over time.
Contribution/ Originality
This study contributes in the existing literature with a new scale that can be used as a support tool in the existing transfer system. With the development of such scale, the transfer score of soccer players will be determined and the change of their performance over time could be observed.

The purpose of this research was to examine the effect of an intervention designed to improve functional movement as determined by Functional Movement Screen ™ (FMS) composite scores, one mile run time, standing isometric hip extension strength, agility T-Test time, and vertical jump in recreational runners (N=12, 7 males and 5 females; Mean Age = 49.08±15.87 yrs.; and mean weekly run volume = 15.96±21.21 miles), while normal running training load was maintained. We employed a two group (Control and Treatment) randomized experimental design. The treatment group (n=6) completed a 6 week intervention using the standard corrective methodology advocated by the FMS organization in combination with their normal run training, while the control group (n=6) continued their normal run training without additional intervention. We found a significant interaction between group and pre/post measure with a large effect sizes demonstrating improvement in the treatment group for the both the 1 mile run time (F = 5.45, p=0.042, Np2= 0.353) and the FMS composite score (F = 10.55, p=0.009, Np2= 0.513). There were no other significant interactions or meaningful effect sizes for any other dependent variable. This study supports the concept that a 6 week standard FMS intervention can result in concurrent improvements in both FMS composite score and 1 mile running performance without a concurrent change in running training load, isometric hip extension strength, vertical jump performance or t-shuttle times, in recreational runners.
Contribution/ Originality
This study contributes in the existing literature by being the first to examine the effect of a corrective intervention for functional movement ability on both FMS score and athletic performance (1-mile run, t-shuttle, vertical jump, hip extension strength) concurrently, while simultaneously controlling for training, in recreational runners.
