title: Analysis of the relationship between personality traits and leadership characteristics of handball coaches of school teams in the state of Rio de Janeiro, Brazil

description: Abstract Aim: This study aimed to investigate the relationship between personality traits and leadership characteristics of handball coaches of school teams in the state of Rio de Janeiro, Brazil. Method: The sample was composed of 31 male individuals (41.71 ± 9.61 years) registered as coaches at the Federation of Student Sports of Rio de Janeiro (FEERJ). The data collection instruments were the Eysenck Personality Questionnaire, the Revised Leadership Scale for Sport and a sociodemographic questionnaire. Results: The Pearson correlation test showed a moderate negative correlation between working time as a coach and coach ages and Psychoticism (P); a moderate positive correlation between Extroversion (E) and Positive Feedback (PF) behavior; a moderate positive correlation between Neuroticism (N) and PF; a moderate positive correlation between N and autocratic behavior. The ANOVA revealed that coaches in the infantile category exhibited higher levels of N than those in the juvenile category. The Social Support (SS) given by the coaches of the junior categories presented superior levels to those of the juvenile category. The SS of the coaches of the infantile category showed higher levels than those of the juvenile category. Conclusion: It was concluded that certain personality traits are associated with the leadership characteristics of the investigated coaches.

title: Cardiac autonomic responses during and after a single session of aerobic exercise with and without blood flow restriction

description: Abstract Aim: To verify the on and off heart rate (HR) and HR variability (HRV) kinetics during a high-load aerobic exercise and a low-load aerobic exercise, with and without blood flow restriction (BFR). Methods: Fourteen healthy male subjects performed three randomly assigned experimental sessions: 1) 10 minutes walking at 40% of maximal aerobic speed (MAS) (40LL); 2) 10 minutes walking at 40% of MAS with BFR (40LL+BFR); and 3) 10 minutes running at 70% of MAS (70HL). The HR and HRV measurements were taken at rest, during exercise and the recovery period after constant load sessions. Results: The HR on- and off- kinetics, and HRV on-kinetics were faster in 40LL than in 40LL +BFR and 70HL (p &lt; 0.05). The time constant (τon) of HR on-kinetics was faster in 40LL+BFR than in 70HL (23.4 ± 9.5 s vs 42 ± 9.5 s, respectively, p &lt; 0.01), and was accompanied by faster HRV on-kinetics (12.4 ± 9.6 s vs 20.3 ± 13.7 s, respectively, p &lt; 0.01). Although HR off-kinetics was not different between 40LL+BFR and 70HL, the recovery of time and frequency HRV indices were delayed in 70HL when compared to 40LL and 40LL+BFR (p &lt; 0.05). Conclusions: These findings indicate that 40LL promoted faster cardiac adjustments compared to 40LL+BFR and 70HL sessions. Additionally, 40LL+BFR promoted faster cardiac adjustment and better HRV recovery compared to the 70HL session.

title: Anxiety increases the blood pressure response during exercise

description: Abstract Aim: The hypothesis that higher levels of anxiety promote greater blood pressure (BP) responses during physical exercise is tested. The hypothesis that metaborreflex response is increased in an anxious individual is tested as well. Methods: There were 43 volunteers divided by anxiety level: 12 volunteers with mild, moderate and severe symptoms (anxious-group) and 31 volunteers with a minimum level of anxiety (control-group). Arterial BP, heart rate, and forearm blood flow were measured simultaneously during handgrip exercise and post-exercise ischemia, and forearm vascular resistance (FVR) was calculated. Results: Anxious group present higher systolic, diastolic and mean BP at rest when compared with control group (130±11 vs. 122±12 mmHg, p=0.048; 70±6 vs. 65±8 mmHg, p=0.033; 90±7 vs. 84±9 mmHg, p=0.033, respectively) and higher response of systolic, diastolic and mean BP and FVR during exercise when compared with control group (20±9 vs. 13±7 mmHg, p=0.009; 17±8 vs. 11±6 mmHg, p=0.006; 18±8 vs. 11±6 mmHg, p=0.005; and 0±13 vs. -7±9 units, p=0,003, respectively). During post-exercise ischemia, the anxious group also present higher response of diastolic BP, mean BP and FVR when compared with a control group (11±12 vs. 3±4 mmHg, p=0,001, 10±8 vs. 3±5 mmHg, p=0,002; 9±11 vs. -2± 8 units, p=0,03, respectively). Conclusion: Anxious individuals present higher BP responses during physical exercise when compared with those with minimal anxiety symptoms. This increased response may be explained, in part, by increased peripheral vascular resistance due to the greater metaborreflex response.

title: Exercises with action observation contribute to upper limb recovery in chronic stroke patients: a controlled clinical trial

description: Abstract Aims: To investigate the effects of an exercise program with action observation versus conventional physical therapy on upper limb functionality in chronic stroke subjects. Methods: In this controlled clinical trial, thirty-five stroke patients were divided into two groups, experimental group, comprising eighteen patients that received an exercise program with action observation; and a control group, comprising seventeen patients that received conventional exercise program. Functional recovery was assessed with the Fugl-Meyer Scale, manual dexterity was assessed with the Box and Blocks test, and the functional use of the affected upper limb was assessed with the Reach scale. Evaluations occurred at baseline, after three and six months of intervention. Statistical analyses were performed with the Repeated Measures Analysis of Variance and the Friedman test, under a 5% significance. Results: Both interventions provided benefits to chronic stroke patients. Exercise program with action observation presented better results on motor recovery (p &lt; 0.001) and functional use of the affected limb (p &lt; 0.001) when compared with conventional therapy. Both treatments improved the manual dexterity of the participants (p = 0.002), but in a similar way (p = 0.461). Conclusion: A six-month exercise program with action observation provided benefits on functional recovery and functional use of an affected upper limb in chronic stroke patients. Exercises with action observation demonstrated the potential for improving affected upper limb in chronic stroke patients.

title: Early intervention program by ICF model for babies of 4-18 months frequenting daycare center: protocol for clinical trial

description: Abstract Introduction: A daycare center is a long-term place for infants, which means that early intervention programs should be thought of in this environment. There are still many gaps regarding the best way of stimulation/intervention, duration and description of effects and controlled outcomes. Aim: The objective of this clinical trial is to propose an early physical activity intervention program performed in infants of 4-18 months with risk/delay and with typical development at infant’s daycare. Method: The protocol of this study is indicated for a controlled trial, in a crossover format, to be applied in 4 groups composed by in 4-18 month-old infants who attend daycare: Intervention group 1 Typical, Intervention group 1 Risk/delay, group Intervention 2 Typical, group Intervention 2 Risk/delay, in 4-18 month old infants who attend daycare. The ICF criteria about functions and structure (through evaluation questionnaire) are considered, as well as activities and participation (AIMS, Denver II, and PedsQl™ evaluation), personal characteristics (questionnaire, ABEP and AHEMD-IS) and environmental factors (AHEMD-IS). Conclusion: This original proposal can highlight a low-cost intervention program performed in a daycare environment verifying the infant's NMD in a systematized way using theoretical basis.

title: The effect of different physical therapy procedures in ultramarathons

description: Abstract Aims: To analyze the effects of physical therapy procedures in reducing acute pain in runners. A second aim was to investigate the impact of weather conditions on the number of physical therapy visits during the Ultramarathon Rio24 h. Methods: This retrospective study was performed at the Physical Education Center Admiral Adalberto Nunes (CEFAN). Medical records were analyzed. The participants were athletes that were attended by the Physical therapy team during three editions of the Ultramarathon Rio24 h. The variation in the Visual Analog Scale score (VAS) before and after each treatment were analyzed. After the evaluation procedure, another professional had decided the best procedure for the assessed athlete: massotherapy, cryotherapy by immersion, or stretching. An ANOVA was performed to assess which procedures produce pain reduction immediately after the procedure. Results: A total of 1,995 care services (228 in women) were performed in 602 athletes (84 women). Analyzing the treatments that used only one modality (n = 512 visits), the final pain decreased significantly over the initial pain for the three treatments. It was verified that massotherapy, cryotherapy, and stretching promote significant intragroup differences, with no intergroup differences. The environmental conditions were not associated with the number of visits. Conclusion: Massotherapy, cryotherapy, and stretching are effective treatments for acute pain reduction during ultramarathons. The weather conditions are not associated with the number of physical therapy visits.

title: Impact of a nutrition education program on gymnasts' perceptions and eating practices

description: Abstract Aims: To understand how participating in a Nutrition & Health Education program (NHEP) affected the way rhythm gymnasts and their coaches perceive their food practices. Methods: Qualitative study portraying a case study of a NHEP specifically designed for a rhythm gymnastic team. The NHEP was conducted at the training facilities. Fourteen rhythm gymnasts, consisting of the team that represents a city in the state of São Paulo, Brazil, and their two coaches participated in the study. Athletes and coaches were interviewed about their perceptions and food practices before and after a 9-month NHEP designed specifically for them. Recorded interviews were transcribed verbatim. Two categories emerged from the discourses and were analyzed using the content analysis: “beliefs and feeding practices” and “construction of a positive relationship with food”. Results: Athletes reported changes in their food practices related to the themes discussed with them in the NHEP, such as daily breakfast intake, higher intake of fruits, vegetables, milk products, and wholegrain foods. Conclusion: The NHEP allowed specific demands of the athletes to be identified and addressed, generating awareness and motivation to positive changes in eating practices.

title: Heart rate responses of a master athlete during ultra-endurance swimming

description: Abstract Aim: Swimming races outside swimming pools take place all over the world, but studies focusing on their physiological aspects are scarce. In fact, rules forbid any direct contact with swimmers during sanctioned events. This case report presents heart rate responses of a master athlete during an ultra-endurance open water solo swim and analyzes results based on a prior cardiopulmonary exercise test. Methods: The swimmer performed a cardiopulmonary exercise test on a treadmill, following a ramp protocol, with continuous electrocardiogram recording. The athlete performed a 36 km swimming race with continuous heart rate recording. Description of swimming heart rate accordingly to heart rate training zones and correlation analysis between HR and swim speed was assessed. Results: The athlete swam the 36 km event in 11 hours, 16 minutes and 15 seconds. Most of the swim time was spent in training zone 3 (55%), and only 2% of race time was spent in zone 5. Swimming speed (3.2 ± 0.7 km/h) failed to correlate with HR during the event (r2 = 0.1334, p &gt; 0.05). Conclusion: Although HR did not correlate with swimming speed it successfully indicated exercise intensity during this 36 km event. These results can be used in the preparation and monitoring of other solo long-distance swimmers.
