The aim of this study was to investigate the effect of two different endurance training protocols based on discontinuous methodology (intermittent and interval), on the VO2Peak of Antioquia's top Judo athletes. To do this, 21 judokas of Antioquia’s judo team, belonging to the category of Major (20.43±4.18 years) were randomized into two experimental groups and a control group. Both experimental groups were trained in endurance for 4 weeks with 4 weekly stimuli, one of the experimental groups was trained based on the interval training method, and the other was trained based on the intermittent method. Meanwhile, the control group made no endurance training. No significant differences between pretest and posttest of both experimental groups, (intermittent and interval training protocols), nor in the control group were found (p> 0.05). It was concluded that the endurance training protocols based on discontinuous methodology, produced no significant difference in VO2Peak of Antioquia's top Judo athletes.

The aims of this study were on the one hand, to describe the performance in a laboratory cardiovascular test and in a repeated sprint ability (RSA) test, and on the other, to analyze the association between the results obtained in both test. Twelve high-standard soccer referees (1st, 2nd y 2nd B Divisions, 28,8±5,1 years, 73,2±6,6 kg, 1,8±0,1 m and 22,82±1,38 kg·m-2) participated in this study. Soccer referees obtained 59,50±4,56 ml·kg-1·min-1 of maximum oxygen consumption (VO2max). Mean time (RSAMedia) spent to perform the repeated sprints in 15 and 30 m distances was 2,54±0,09 s and 4,43±0,14 s, and total time (RSATotal) was 15,26±0,53 s and 26,60±0,82 s, respectively. Fatigue indexes (RSASdec and RSACambio) in 15 and 30 m distances were 2,25±1,05% and 3,33±1,59%, and 3,45±2,92% y 6,31±4,63%, respectively. Positive associations were found between cardiovascular variables and RSA time variables. On the other side, oxygen consumption at ventilatory threshold 1 (VT1) and ventilatory threshold 1 (VT2) and fatigue index (RSASdec) correlated negatively. Despite a higher cardiovascular capacity in soccer referees may generate a negative effect on the time spent in RSA, it also minimize the fatigue during repeated sprints. Physical trainers should focus the training of soccer referees on the cardiovascular capacity and they should implement acceleration specific training.

Objective: To determine the effect of a fitness program in the posture of instrumentalists from the University of Cauca, applied during 2015. Method: A descriptive longitudinal quasi-experimental study was conducted in 9 members of the Wind Ensemble of Metal Music program; The information was collected through a tab that were reported sociodemographic characteristics, lifestyle and muscle strength; with Kinovea program, the position of the upper quadrant was evaluated; and then a fitness program was applied; after the implementation of the program, the position of the upper quadrant and muscle strength was revalued. Results: With the application of fitness program, 100% of participants showed a reduction in deviation angles upper quadrant, mainly skull and vertebral angle in the alignment of the cervical-thoracic spine in the side view. Conclusion: With the application of fitness program, a positive clinical change manifested in decreasing degrees of alteration in postural angles of the upper quadrant evidence.

Using observational methodology as a means, we have analyzed three actions ball stopped very common in football such as corner kicks and free kicks direct and indirect, to develop and generalize an observation tool. The data recording was made on UD Almeria matches of the 2006-2007 season in the 2nd national division. For this we used a nomothetical design monitoring and has been made intermittent recording coded data as multiple events, then making an analysis of the quality of data to ensure the reliability of the register, where data were subjected to analysis variance components and generalizability analysis. In conclusion we can highlight the confirmation of the reliability and generalizability of the observation tool constructed and the absence of significant differences in the overall behavior of the teams observed in the corners and direct and indirect free kicks

This research has been developed in the class of classical dance technique Conservatory of Dance, an environment where discipline, rigor and meticulousness coexist with creativity, expression and sensitivity. The main objective of the study is to analyze the methodological, didactic and pedagogical differences, using a methodology of joint research between the given class with recorded music (CD) and class with teacher accompanist dance since the work of the latter continues necessitating despite today's digital media. Two classes in which the only difference was the music stand was analyzed by video recording, observation sheets and questionnaires. significant differences between the two sessions, such as an average of 38 seconds to search for the needed music for each variation with CD versus six seconds recorded in the session with pianist or found greater number of journeys to the sound source by the teacher in the case of CD in addition to motivational aspects, and emotional differentiated and methodological proving more effective and productive use of live music versus recorded music.
