title: Motor learning in post stroke subjects: the effects of practice conditions on the temporal synchronization

description: Abstract AIMS The aim of this study was to investigate the effects of practice schedule on the motor learning of a synchronization timing task in post-stroke subjects. Subjects and METHODS Seventeen post-stroke individuals were assigned to the experimental group and for the control group were selected seventeen healthy individuals. At the acquisition phase, all participants performed 30 trials of a coincident timing task. Nine individuals from each group practiced constantly and eight from each group practiced randomly, with speed changes in the task. Subsequent phases included: 1) immediate transfer test and 2) long term transfer test after 3 days. Data were analyzed in relation to absolute, variable, and constant errors to assess the performance concerning accuracy, consistence, and direction of responses, respectively. RESULTS All groups increased their accuracy through the practice and were able to adapt it in different speeds. The stroke subjects were more variable in their motor responses. There was no effect of the practice schedule on motor learning, regardless the presence or absence of the neurologic damage. CONCLUSION Post stroke individuals were able to learn a synchronizing task and the capacity of adapt their performance after speed perturbation was preserved. There was no effect of the practice schedule on motor learning.

title: Efficacy of neurofunctional versus resistance training in improving gait and quality of life among patients with Parkinson’s disease: a randomized clinical trial

description: Abstract AIMS to compare the efficacy of neurofunctional training versus resistance training in improving gait and quality of life among patients with PD METHODS This randomized controlled trial included 40 participants randomly assigned to two groups through random number table generator: resistance training (RT) (n=19) and neurofunctional training (NT) (n=21). The RT group performed resistance exercises emphasizing the lower limbs and trunk, while the NT group sessions were focused on gait, functional independence and balance training. Trained physical therapists supervised both groups. The training sessions lasted 60 minutes in each group and were performed twice a week, totalizing 24 sessions. The outcomes, gait and quality of life, were measured using video gait analysis and footprint analysis; and PDQL and PDQ-39 questionnaires, respectively RESULTS intra-group comparison revealed all gait variables (stride length, step length, number of steps, time of distance walked, gait speed and cadence) improved after the NT intervention with large effect size, while only stride length improved in the RT group with moderate effect size. The between group analyses means (Δ) shows that all the variables presented statistically significant differences in the NT group. Additionally, both groups showed significant improvements in quality of life. CONCLUSIONS The application of specific neurofunctional training, directed and enriched with sensorial resources, resulted in superior gait performance among individuals with PD when compared to those in the resistance training group; both treatments were efficacious in improving quality of life.

title: Futsal improve body composition and cardiorespiratory fitness in overweight and obese children. A pilot study

description: Abstract Aims: The aim of this study was to verify body composition, cardiorespiratory fitness, and biochemical markers of prepubertal overweight and obese boys to a 16-week futsal training program. Methods: Sixteen boys (age: 7-10 y, body mass index&gt;thanat 95th percentileaccording to Center for Disease Control and Prevention; 35.5±7.4 percent fat) participated to futsal training program. The assessment of body composition was estimated using skinfold thickness, and the following variables were evaluated: total body mass, body mass index, body fat percentage, and lean body mass. Aerobic fitness measurementwas performed by gas exchange analysis in treadmill. In addition, an evaluation of the biochemical profile was conducted: triglycerides, total cholesterol, low density lipoprotein cholesterol, high-density lipoprotein cholesterol, plasma concentrations of glucose, and insulin. The futsal intervention included 60-min sessions performed two times/week. The mean intensity during training was between 57 to 88% of maximal heart rate of the age-predicted. Individual portable heart rate monitor controlled training intensity. Results: Significant increases in total body mass (4%), height (3%), lean body mass (8%), and significant 6%-decrease in body fat percentage was observed. Body mass index remained unchanged. Maximal oxygen uptake was elevated (p&lt;0.018) by 11%. Biochemical markers were not modified after intervention. No association was found between body composition and metabolic variables. The effect size of futsal training on most variables was small (&lt;0.5). Conclusion: Controlled intensity and adherence to this 16-week futsal training program were determinant to enhance body composition, and cardiorespiratory fitness in this group of prepubertal boys.

title: Teaching handball to U-16 and U-18 women’s teams: coaches’ perspective on the long-term

description: Abstract Aims: To identify the teaching approaches preferred by Brazilian coaches in the U-16 and U-18 women’s teams and whether it is possible to apply long-term goals for handball training. Methods: Six experienced coaches were interviewed individually in a semi-structured format. Data were transcribed and analyzed according to the Collective Subject Discourse (CSD) method. Results: Coaches revealed a choice for the situational approach and global-functional approach in U-16 teams. In U-18 teams, coaches’ choices were for the technique and situational approaches. The change of coaches’ choice might be based on players’ specialization, suggested to U-18 teams when coaches highlighted the increased demand for performance. On players’ transition from U-16 to U-18 teams, the coaches showed less preference for the global-functional approach and increasing evidence of the technique approach. Conclusion: Global-functional and situational approaches should be given a prominent position in these teams, especially due to the development of technical-tactical aspects. However, the technical approach was recognized as a central position in U-18 teams, probably related to players’ specialization and technical improvement, although it does not offer a rich environment for the development of players’ decision making.

title: Effects of different frequencies of physical training on electron transport chain and oxidative damage in healthy mice

description: Abstract Aims: The present study investigated the effect of different frequencies (three and five times a week) on electron transport chain and oxidative stress after 8 weeks of run training. Methods: Eighteen male mice (CF1, 30-35g) were distributed into the following groups (n=6): untrained (UT); trained three-time per week (T3) and trained five- time per week (T5). All training sessions were at the same intensity and duration (45min/day) in a treadmill for small animals. Forty-eight hours after the last training session, the animals were killed by decapitation and quadriceps (red portion) was removed and stored at -70ºC. Succinate dehydrogenase (SDH), complexes I, II, II-III, IV and hydroperoxides were measured. Results: Training sessions for five times per week were more effective in increasing the mitochondrial respiratory chain enzyme activities (SDH, complexes I, II, II-III, IV) as well as in decreasing the formation hydroperoxides than sessions performed for three times training per week (p&lt;0.05). Conclusion: Our findings clearly showed that a higher the frequency of training session promotes a greater activity of the electron transport chain and consequently reduces the oxidative stress in healthy animals.

title: Exploring the effects of deep-defending vs high-press on footballers’ tactical behaviour, physical and physiological performance: A pilot study

description: Abstract AIMS The aim of this study was to explore the effects of a deep-defending vs high-press defending strategy on footballers’ tactical behaviour, physical and physiological responses, when in numerical difference. METHODS Nineteen elite professional footballers (outfield players) participated in this study, playing an 11vs10 match (simulating an early dismissal) for two halves of 10 minutes on a full-sized regulation pitch. The 11-men team was instructed by the head coach to defend closer to goal in the first half (deep-defending) and then defend higher up the pitch in the second half (high-press). Players’ positional data were used to calculate the distance between team centroids, players’ distance to own and to opponent centroid, teams’ effective playing space (EPS), teams’ length per width ratio, distance covered and player velocity. Heart rate was measured via short-range radio telemetry. RESULTS Relative-phase analysis of teams’ EPS showed 61.6% of anti-phase synchronisation pattern (i.e. the values change in opposite directions) in the deep-defending game. In the high-press game, teams’ centroid distances were closer (% difference in means; ±90% CL, -21.0%; ±9.5%), while players’ distances to own and opponent centroids were 20% more regular. Distance covered (-19.8%; ±2.5%), player velocity (-20.0%; ±2.5%) and heart rates also decreased in the high-press game. CONCLUSION These findings suggest that, adopting a high-press defending strategy can elicit closer centroid distances, more regular movement patterns, decreased synchronisation patterns of EPS, lower distance covered, lower player velocity, and lower heart rates. Coaches may also consider adopting a high-press strategy, when in numerical superiority, to decrease players’ physical and physiological demands.

title: Fat mass is negatively associated with the physiological ability of tissue to consume oxygen

description: Abstract Aims: To describe the relationship between variables related to body composition and peak oxygen uptake ( V ˙ O 2peak) and to verify whether fat mass can affect these relationships. Methods: Eighty participants underwent cardiopulmonary exercise testing to measure V ˙ O 2peak and a body composition assessment to measure fat mass, fat free mass (FFM), and total body mass (BM). Results: There were significant relationships between V ˙ O 2peak relative to FFM (fat free mass) (mL/kgFFM/min) and absolute fat mass (kg) (r=-0.50, p&lt;0.001) and relative fat mass (%) (r=-0.56, p&lt;0.001). Absolute V ˙ O 2peak (L/min) had a high positive relationship with FFM (r=0.83, p&lt;0.0001); the relationship between V ˙ O 2peak (L/min) and FFM remained high and positive even when accounting for absolute fat mass (kg) (r=0.83, p&lt;0.001). V ˙ O 2peak relative to total body mass (mL/kgBM/min) showed a high negative relationship with relative fat mass (%) (r=-0.89, p&lt;0.001) and a positive relationship with fat free mass (kg) (r=0.57, p&lt;0.001), which did not change when accounting for fat mass (kg) (r=0.56, p&lt;0.001). Conclusion: These data indicate that the physiological ability of tissue to consume oxygen ( V ˙ O 2peak in mL/kgFFM/min) is negatively associated with fat mass. Moreover, the individual’s cardiorespiratory capacity to transport oxygen for working muscles ( V ˙ O 2peak in L/min) is strongly related to absolute FFM, and this association is not affected by fat mass. Finally, a better body mass composition (high FFM and low fat mass) is important for aerobic physical fitness ( V ˙ O 2peak in mL/kgBM/min) and improved physiological ability of tissue to consume oxygen ( V ˙ O 2peak in mL/kgFFM/min).

title: Bench press exercise performed as conditioning activity improves shot put performance in untrained subjects

description: Abstract Aims: The aim of the present study was to evaluate the effect of bench press exercise performed as conditioning activity on the shot put performance in untrained subjects. Methods: Twelve healthy men (26 ± 6 years; 1.8 ± 0.1 m; 73.5 ± 10.4 kg; 13.2 ± 5.2% body fat), with no experience in shot put, were randomly assigned into two conditions: 1) Control: subjects performed six shot put attempts, and 2) Bench press exercise: subjects performed six shot put attempts 7 min post 2 sets of 5 repetitions maximum (RM) of bench press exercise. A metal ball of 4 kg was used for shot put attempts, and subjects were instructed to perform each shot put according to the static shot put technique. Results: Shot put performance was greater after bench press condition when compared with control condition (8.2 ± 1.2 m vs. 7.8 ± 0.8 m, respectively, p &lt; 0.05). In addition, eight out of 12 volunteers positively responded to the conditioning activity. Conclusion: The results suggest that bench press exercise performed as a conditioning activity improves shot put performance in untrained subjects. Moreover, the conditioning activity should be individually set.
