    (Federacion Espanola de Docentes de Educacion Fisica, 2024) González-Orb, Marcelo; Vargas Vitoria, Rodrigo; Valderrama Jorge, Flandez; Lobos-Gonzalez, Rodrigo, Manuel
    Descriptive study whose objective is to determine the quality of training of Pedagogy students in Physical Education, in six University entities, based on the domain of seven dimensions associated with the Curricular Bases: Expression, Didactics, Management, Training, Sports, Recreation, Health and First Aid. Material and Method: The population and sample is made up of students in the last year of the degree, N=214, n=133 men and n=81 women. The instrument used, the 70-item Specialty Knowledge Test, with an internal consistency of .778, an average difficulty index of 0.59, an average high discrimination index of 0.39 and a good discrimination coefficient of 0.25, that is, appropriate. Results, statistically significant differences were observed by sex favorable to women in Expression (p=.014) and men in Training (p=.014) and Sports (p=.014). There are no significant differences by sex in Didactics, Recreation Management, Health and First Aid, and in General (p>.05). Conclusions: the training in general terms presents weaknesses in all the dimensions under study, qualifying it as regular. The mastery of the students regarding the Curricular Bases of Physical Education, MINEDUC, are at low levels. There is no correlation between gender and knowledge, although the results are favorable to men, they are not statistically significant with respect to women. The comparative table of dominance between the universities, allows establishing that an entity presents better scores, being far from the ideal, finally the training of the students (as), is located in the regular range, far from the ideal. © Copyright: Federación Española de Asociaciones de Docentes de Educación Física (FEADEF

    Introduction: In tennis, stroke speed is a characteristic factor of the game, so studying specific determinants is very valuable. Objective: To analyze the association between stroke velocity and anthropometric indicators, fat tissue and explosive muscle strength in young female tennis players. Methodology: Cross-sectional and correlational-descriptive study. Twenty-nine female tennis players (16.3±0.7 years) were evaluated. Height, body weight and skin folds were recorded. Body fat percentage (GC) was calculated. In addition, service, forehand and backhand velocity were measured with a speed radar (Pocket Radar®). Explosive muscle strength was determined by medicine ball toss (MBT), horizontal jump (SH) and countermovement jump (CMJ) tests. The study was approved by a competent ethics committee in the area of a Chilean university. Results: The LBM showed a positive association with serve velocity (R2=23%), forehand (R2=17%) and backhand (R2=15%). An increase in LBM distance was positively related to an increase in stroke velocity (β= 0.07; 0.07; 0.06 km/h, respectively). Likewise, service velocity was negatively associated with ∑2 skinfolds (R2=29%), GC (R2=28%) and body weight (R2=29%). Discussion: These results partially coincide with other studies where it has been reported that upper body explosive muscle strength, fat tissue and body weight are components of physical performance that can increase stroke speed. Conclusions: The stroke speed is mostly associated with LBM. On the other hand, the service velocity is negatively related to indicators of adiposity and body weight. © 2025 Federacion Espanola de Docentes de Educacion Fisica. All rights reserved.
