- New technologies to the study the golf puttingPublication . Fernandes, Orlando; Dias, Gonçalo; Couceiro, Micael; Manuel Clemente, Filipe; M. L. Martins, Fernando; Luz, Miguel; Mendes, RuiThe technology evolution, especially in the last decade, allowed major advances in golf putting analysis. This scientific advance benefited from multidisciplinary interaction, such as: biomechanics, engineering, mathematics and motor control. Utilizing digital cameras along automatic tracking techniques, it is possible to obtain valuable and accurate information about the putting gesture and/or ball trajectory. This can provide relevant feedback to athletes and coaches. In this work, we present several golf putting studies conducted on laboratorial environment. We believe that this work may contribute to a deeper analysis of human motor behavior and performance, not limited to this motor skill, but that can be applied to other motor patterns.

- Technical performance and aerobic fitness in padel amateurs players with different practice levelsPublication . Mendes, Pedro Cabral; Gomes, Ricardo; Furtado, Guilherme Estáquio; Amoroso, José; Lemos, Samuel; Dias, Gonçalo; Mendes, Rui. The aim of this study is to compare the precision of low and high-level padel players in a closed task and its relationships with the heart rate responses to the exercise. A sample of 49 male players of two practice levels (age, 36.73±1.50) was selected to participate in this study. Technical performance was analysed through the Groundstroke Padel Accuracy Test (GPA) and heart rate during and after the task was monitored. There were no statistically significant differences in the GPA test, but even so the results showed a heart rate recovery at 60 and 120 sec were significantly higher for the high-level group [HRR1, U = 189, p = 0,026, d = 0,32 (moderate effect); HRR2, U = 186,50, p = 0,023 d = 0,32 (moderate effect)]. We conclude that it would be relevant to measure other product variables in order to make this field test (GPA) even more effective in the evaluation the real technical level of padel players. Additionally, high-level players recuperate faster after the effort, which appear to indicate that they may be better aerobically prepared.
- Team’s performance on FIFA U17 World Cup 2011 : study based on notational analysisPublication . Manuel Clemente, Filipe; Couceiro, Micael; M. L. Martins, Fernando; Mendes, RuiThe main objective of the notational analysis of the game includes optimizing feedback to the performer and coach to improve performance (Liebermann, Katz, Hughes, Bartlett, McClements & Franks, 2002). The main objective of this work was to analyze the profile of the teams that competed on FIFA U-17 World Cup at 2011, most exactly, trying understanding the offensive profile of the most successful teams. In this way we applied the test of correlation to verify if the goals for average are related to number of matches (i.e., more successful teams). There is statistical evidence to assert that the pairs (wins and goals) are positively moderating related (p = 0.001). In fact it appears that there is a directly intimacy between pairs (since the linear correlation coefficient r (24) = 0.774), i.e., how much more goals for average, more wins happens. Through the analysis of dependent variables is possible to say that teams who wins more games, have a superior mean of goals per match but, in the case of goals against, the teams that achieve the higher level in competition have higher mean of the goals against. However are the teams that play more matches that show higher level of goals for average.
- Young people, drug use and drugged-drivingPublication . Silva, Fátima Pereira da; Mendes, Rui; Girão, Patrícia; Francisco, MarianaAccording to World Health Organization (WHO) road traffic injuries are a leading cause of death globally, leading to the death of 1.2 million people each year. Data from National Authority for Road Safety (ANSR-Portugal) points to age group between 18 and 24 years old as the most vulnerable facing road dangers. In the last 10 years 15% of fatalities, 18% of serious injuries and minor injuries happened in this age group. It is also in this younger group that most accidents occur during weekend nights compared to the other days of the week. This article aims to present the results of a preliminary study about drug use and drugged-driving, through the application of the DDYP-Scale Questionnaire to 140 young people. For data analysis, descriptive and inferential statistical analyses were applied. Results presented here, although somewhat different from American and European studies, indicate a clear tendency to the recreational use of marijuana and drugged-driving, among younger populations.
- Network analysis in basketball : inspecting the prominent players using centrality metricsPublication . Manuel Clemente, Filipe; M. L. Martins, Fernando; Kalamaras, Dimitris; Mendes, RuiThe aim of this study was to analyse the team-members cooperation in basketball by using centrality metrics of network. Different ages were compared in this study. Forty players (10 players of under-14; 10 players of under16; 10 players of under-18 and 10 players in amateurs with more than 20 years) voluntarily participated in this study. A total of 326 units of attack were generated based on the team-members interactions and then converted in final graphs. The one-way ANOVA for the factor tactical position found statistical differences in the dependent variables of %DCentrality (F(4,15) = 13.622; p-value = 0.001; n2 = 0.784; Large Effect Size) and %DPrestige (F(4,15) = 20.590; p-value = 0.001; n2 = 0.846; Large Effect Size). In conclusion this study showed that point guard was the prominent position during the attacking organization and that social network analysis it is a useful approach to identify the patterns of interactions in the game of basketball.
- Weekly physical activity patterns of university students : are athletes more active than non‑athletes?Publication . Manuel Clemente, Filipe; Nikolaidis, Pantelis Theodoros; M. L. Martins, Fernando; Mendes, RuiThe aim of the present study was to compare weekly physical activity (PA) and obesity-related markers in athlete and non-athlete university students. One hundred and twenty-six university students (53 males, 20.46 ± 2.04 years old, and 73 females, 19.69 ± 1.32 years old) participated in this study. Participants were fitted with a tri-axial accelerometer (ActiGraph wGT3X-BT, Shalimar, FL, USA) to assess the daily PA. Anthropometric measures of height, weight, BMI and %fat mass were determined with a stadiometer and an electronic scale. The comparison indicated that male and female athletes had a significant lower percentage of body fat than did non-athletes (p value = 0.001; ES = 0.043). Athletes spent significantly more time in light PA than did non-athletes (p value = 0.003; ES = 0.024). Female athletes spent significantly less time in sedentary mode than did non-athletes (p value = 0.040; ES = 0.008). On the other hand, female athletes spent significantly more time in light PA (p value = 0.003; ES = 0.017) and vigorous PA (p value = 0.001; ES = 0.086) than did non-athletes. Despite some statistical differences with minimal effect size, the results of this study suggested proximity between PA levels of athletes and non-athletes, mainly in the case of sedentary behaviour. No significant effects were found in the variances of PA tested in this study.
- Inspecting the performance of neutral players in different small-sided gamesPublication . Manuel Clemente, Filipe; M. L. Martins, Fernando; Mendes, Rui; Campos, FranciscoThe aim of this study was to inspect the effects of format and task conditions on neutral players' heart rate responses and time-motion characteristics. Four formats of play using neutral players and three task conditions were inspected. Moreover, the factor repetition (3 games per each SSG) was also analysed. Ten male amateur soccer players (26.36 ± 5.33 years old, 8 ± 3.2 years of practice, 66.18 ± 10.16 bpm at rest) participated in this study. The repeated measured revealed that no differences were found between repetitions (Pillai's Trace = .075; F 8, 100 = 1.007; p-value = .436; = .075; Power = .445; small effect size). In the game 1 significant interaction effects between the two factors on heart rate responses and time-motion profiles were observed (Pillai's Trace = 0.699; F 24,428 = 3.774; p-value = .001; = .175; Power = 1.000; moderate effect size). In the game 2 , significant interaction effects between the two factors on heart rate responses and time-motion profiles were observed (Pillai's Trace = .712; F 24,428 = 3.860; p-value = .001; = .178; Power = 1.000; moderate effect size). Finally, in the game 3 significant interaction effects between the two factors on heart rate responses and time-motion profiles were observed (Pillai's Trace = .729; F 24,428 = 3.972; p-value = .001; = .182; Power = 1.000; moderate effect size). Briefly, it was possible to conclude that the biggest formats statistically increased the heart rate responses and time-motion characteristics of neutral players. It was also possible to observe that the mean values of heart rate responses found in neutral players throughout small-sided games were appropriated to very light or recovery workouts.
