The purpose of this study was to investigate the predictors contributing to be in the first three places with right arm in women armwrestling. Thirty-one female senior armwrestlers competed in Turkish National Championship voluntarily participated in this study. The data were collected from six different weight classes. Handgrip strength, auditory reaction time, forearm length, and forearm circumference were determined as the predictors. All the measurements were taken after weigh-ins had been done and before the first day of national championship competition. Logistic regression analysis was conducted to predict whether a competitor in women armwrestling would be in the first three places with right arm, to be a winner or non-winner. Relative handgrip strength and forearm length were found significant predictors (p < .05). This result suggests that strength can be viewed as the main predictor in right arm ranking for women competitors; however, in order to apply different techniques during the match, forearm length also found to be an effective factor to be a winner. Thus, this anthropometric measurement can be used for the talent identification for women armwrestlers.

The aim of this study was to investigate the effects of different types of feedback on learning soccer “head kick” of female adolescent. Novices performed head kick during two practice days [one week apart) for two weeks using either internal or external preference attentional focusing instructions. There was also a preference group who choosen their feedback type themselves. Internal focus feedback related with body movements, whereas external focus feedback related with movement effects. The subjects (N=64) were randomly assigned to three groups internal focus feedback group (IFF) (N=15), external focus feedback group (EFF) (N=15) and preference group (PF) (N=34). To promote learning two skill acquisition days for two weeks and one retention day was applied at initial day of third week. Technique of the skill was measured in acquisition days and targeting was measured in retention day. In technique measuring part, EFF group was significantly more accurate than IFF group, PF group was better than those two groups (PF>EFF>IFF). Similar to acquisition phase, EFF group was significantly more successfull than IFF group, PF group was better than those two groups (PF>EFF>IFF )in retention phase. Acquisition and retention phase results indicated significance main effect for attentional focus feedback groups. This study results’ indicated that external focus feedback was more effective than internal focus feedback in terms of acquisition and retention of learning soccer head kick for students with limited amount of knowledge about this skill. This study also indicated that not only the source of attention but also control over to source of attention of preference was an important factor in the amount of retention.
