Visual search has been considered one of the most important aspects within the process of decision-making in soccer (Williams and Davids, 1998). Literature shows that there are differences on visual search between different competitive levels but in relation to different age groups further investigation is still necessary. The sample comprised 51 youth soccer players. The instrument used to collect and analyse data was the Mobile Eye Tracking – XG (Applied Science Laboratories, Bedford, MA, EUA). This system is used to verify gaze behaviour through visual focus. Players were grouped according to their age group : U-13 (17), U-15 (17), U-17 (17). Video stimuli were the same as that employed by Mangas (1999). Visual search stimuli were grouped in five categories: “player in possession of the ball”; “ball”; “teammates”; “opponent”; “space”. The number of fixations made by players, in each stimuli category was analysed. Data distribution was verified through Shapiro-Wilk's test. One-way ANOVA was performed to compare mean values between the three groups. Results displayed significant differences in one of the categories. The “space” category displayed significant differences between U-13 (74.35±12.41), U-15 (58.78±14.22) and U-17 (61.88±16.44). No other significant differences were found in other categories. These findings are related to the specific sports development phase of each age group. The U-13 was the category that employed most of the visual search related with “space” unlike the U-15 and U-17 age groups. These differences might be related to the specific knowledge of soccer, which is usually lower in younger players. These findings are important for coaches and researchers to understand how visual search strategy change according to the age group.

Aim: The study aimed to verify the effect of carbohydrate (CHO) mouth rinse on time to exhaustion, energy systems contribution and rating of perceived exertion (RPE) during a high-intensity exercise. Methods: Fourteen men performed an incremental exercise test to determine their maximal oxygen uptake and peak power output (PPO) and two time-to-exhaustion tests at 110% of PPO. Participants rinsed their mouth with 25ml of 6.4% of CHO or placebo (PLA) solution immediately before the time-to-exhaustion test, using a crossover design. The contribution of the energy systems was calculated using the free software GEDAE-LaB®. Results: Time to exhaustion was similar between the conditions (CHO:174.3±42.8s; PLA:166.7±26.3s; p=0.33). In addition, there was no difference between the CHO and PLA condition for aerobic (CHO:135.1±41.2kJ and PLA:129.8±35.3kJ, p=0.34), anaerobic lactic (CHO:57.6±17.1kJ and PLA:53.4±15.1kJ, p=0.10), and anaerobic alactic (CHO:10.4±8.4kJ and PLA:13.2±9.2kJ, p=0.37) contribution. Consequently, total energy expenditure was similar between conditions (CHO:203.2±46.4kJ and PLA:196.5±45.2kJ, p=0.15). However, CHO mouth rinse reduced the RPE at the moment of exhaustion (CHO:18.2±1.0units and PLA:19.1±1.1units; p=0.02). Conclusion: CHO mouth rinse neither increased time to exhaustion nor altered energy systems contribution during a high-intensity exercise, but reduced the perceived effort at the exhaustion.

— Aim: The aim of the study was to analyze the lifelong content of learning of coaches. Methods: Eight coaches inserted in an Elite Football Club participated. Rappaport Time Line and semi-structured interviews were used to obtain the data. The coaches’ learning was organized according to the theory of Lifelong Learning. 1-4 Results: The coaches presented in their personal experiences, with their families and as athletes, content of learning such as “leadership development” and “formation of values”. In professional experiences, such as in academic training, coach assistants and even coaching, they are also reported as essential in obtaining content of learning (general and specific knowledge, training methods, leadership development, self-control). Finally, the reflexive process is considered by most coaches as a potentiator of learning, with interference on the “coach-athlete relationship”, “activity adjustment,” among other content of learning. Conclusion: The content learned throughout the life were defined in certain episodes for presenting different meanings in the life of the coaches, in which they related to a new experience according to their biographies. Therefore, the various episodes offer coaches new experiences, in which they can incorporate, reinforce or renew the content about the coaching process and are responsible for the development of the coach. there I came to understand that these games are interconnected, zonal marking in handball, the transitions that basketball requires, the fast decision making in futsal and I searched to associate a lot of what we learn with football.”

— Aims: The purpose of this study was to investigate the effects of the combination of constant and variable practice when both, motor program and parameters on absolute and relative dimensions of a task, are manipulated. Method: Twenty undergraduate students, aged between 19 and 24 years, participated in this study. Two groups practiced the task of pressing four keys of a numeric keyboard with total and relative times specified under constant conditions in the first part of the acquisition phase and under block conditions in the second part when one group varied parameters and another varied motor programs. Results: Both groups improved parameters and motor program measures during the acquisition phase. In the retention test, the parameters variation resulted in higher accuracy on motor program measure than variation of motor programs. Conclusion: Both combinations improve parameters and motor program accuracy. Moreover, the maintenance of GMP during the variation phase contributes to strengthening it.

Aims: Maternal low-protein diet induces several impairments on cardiac system. Conversely, moderate exercise has been widely recommended to health improvement due to its effects on heart function. Thus, we investigated whether the moderate physical training is capable to offset the lasting injuries of a maternal protein restriction on the hearts of male adult rats. Methods: Pregnant rats were divided into two groups: Control (C=17% casein) and undernutrition (U=8% casein). Offspring from the undernutrition group, at 60 days of life, were subdivided into undernutrition (U) and undernutrition+exercise (UT) groups. Treadmill exercise was performed: (8 weeks, 5 days/week, 60 min/day at 70% of VO2máx). 48 hours after last exercise session, tissues were collected for morphological and biochemical analysis. Results: Despite the deleterious effect induced by low-protein diet, physical training was able to restore morphological parameters to similar levels to the control group. Additionally, oxidative stress index was also improved in UT group, due to the increase in antioxidant enzymatic defense. In metabolic enzymes, maternal low-protein diet induced a change in metabolism, and moderate physical training improved oxidative metabolism. Conclusion: We demonstrated that moderate physical training can offset the cardiac metabolism in adult rats that were exposed to a maternal low-protein diet.

Aim: the aim was to investigate the influence of a maximal isometric muscle action of the elbow extensors on the contralateral dynamic task of the elbow flexors. Methods: Seventeen recreationally trained men (23.3 ± 4.9 yrs, BMI: 24.8 ± 2.2 Kg/m2) underwent two randomized different testing sessions separated by one week. In the control session (CON) all subjects performed a maximum number of repetitions test (RMs) at 75%1RM using the right elbow flexors. The experimental session (EXP) was similar to the CON; however, all subjects were instructed to perform RMs at 75%1RM by using the right elbow flexors and maintaining the maximal voluntary contraction of the left elbow extensors during the test. RMs, rating of perceived exertion (RPE), and training volume (TV) were measured and compared between sessions. Results: The EXP showed a significant 10.4% increase on the RMs (13.8 vs. 12.5, p < 0.001, d = 0.44) and 12.1% increase in TV (238.0 vs. 212.4 kg, p < 0.001, d = 0.43) than CON. No differences were observed for RPE between sessions. Conclusion: The maximum voluntary contraction of the left elbow extensors increased the RMs of the contralateral elbow flexors, reflecting a higher TV, and no differences in the RPE. Our results suggest that the investigated method may be a viable and practical alternative to increase the acute strength performance of elbow flexors when using submaximal loads.
目的:探讨肘关节伸肌最大等距肌运动对肘关节屈肌对侧动态任务的影响。方法:17名接受休闲训练的男性(23.3±4.9岁，BMI: 24.8±2.2 Kg/m2)随机进行两次不同的测试，间隔一周。在对照组(CON)中，所有受试者使用右肘屈肌进行75%1RM的最大重复次数测试(RMs)。实验阶段(EXP)与CON相似;然而，所有受试者都被指示在测试期间使用右肘屈肌并保持左肘伸肌的最大自愿收缩，以75%1RM进行均方根。测量RMs，感知运动等级(RPE)和训练量(TV)，并在两次训练之间进行比较。结果:与对照组相比，EXP组RMs增加10.4% (13.8 vs. 12.5, p < 0.001, d = 0.44)， TV增加12.1% (238.0 vs. 212.4 kg, p < 0.001, d = 0.43)，两组RPE无显著差异。结论:左肘伸肌的最大自主收缩增加了对侧肘屈肌的RMs，反映了更高的TV，而RPE没有差异。我们的研究结果表明，所研究的方法可能是一种可行的和实用的替代方案，以增加肘关节屈肌在使用次最大负荷时的急性强度性能。

Methods: Observational study with 86 kidney transplant individuals, subjected to evaluation of the Functional Independence Measure (FIM) and Timed Up and Go test (TUG). Results: The mean age of the study population was 43.98 years old, 50% of these individuals were between 5-10 years of transplantation and 50% between 10-15 years. Changes in mobility and balance (TUG) were found in 9.3% of transplant patients, while 2.3% had deficits in functional independence (FIM). The association between TUG and the FIM (χ2= 19.964, p< 0.001) was found in 25% of the 9.3% of individuals who showed changes in TUG. It was found that only 20.9% of kidney transplant between 5-10 years and 14.0% between 11 and 15 years performed regular physical exercises (χ2= 0.727, p= 0.394) and 67.4% presented prevalent complaints on lower limbs musculoskeletal. Conclusion: Although the level of dependence and impairments in mobility and balance found in renal transplants are low, deficits in mobility and balance may lead to changes in the ability to perform their functional activities independently.
