title: CARDIAC AUTONOMIC ALTERATIONS IN DIFFERENT TACTICAL PROFILES OF BRAZILIAN JIU JITSU

description: ABSTRACT Introduction Brazilian Jiu Jitsu (BJJ) is an individual sport, characterized by intermittent body movements aimed at the submission (defeat) of the opponent. The sport involves two tactical profiles of fighters: the guard (GG) and the passer (PG), which present potential differences in relation to anthropometric patterns and cardiac autonomic modulation. Objectives To evaluate the effects of different BJJ fighting styles on cardiac autonomic modulation. Methods Twelve PG-style athletes and 12 GG-style athletes, both male, with mean ages of 30.4 ± 1.9 and 30.6 ± 1.3 years, respectively, participated in the study. The following measurements were taken at rest: anthropometric profile, body composition and hemodynamic parameters (blood pressure [BP], basal heart rate [HR] and heart rate variability [HRV], the latter through linear and nonlinear analysis). Results The PG fighters had higher waist and hip circumference diameters compared to the GG fighters (p &lt;0.05). There were no differences regarding baseline hemodynamic parameters of HR and BP. Total HRV as well as parasympathetic modulation indices in both the time and frequency domains were significantly lower in the GG fighters than in the PG fighters (p &lt;0.05). In contrast, the sympathovagal modulation markers in the frequency domain, and the sympathovagal index, were higher in GG than in PG (p &lt;0.05). The SD1 index of nonlinear analysis was lower in the GG fighters than in the PG (p &lt;0.05). Conclusion In general, guardian style fighters have lower vagal modulation and cardiac sympathetic hyperactivity at rest, compared to passing fighters. Level of evidence IV; Case series.

title: ANTHROPOMETRIC VALUES OF SPANISH BEACH VOLLEYBALL PLAYERS IN RELATION TO SPORTS PERFORMANCE LEVEL

description: ABSTRACT Introduction Since its debut at the 1996 Atlanta Olympics, beach volleyball has grown on the international sports scene. An extensive collection of data from several countries and levels of competition will provide a database that can be used to characterize beach volleyball players and define references for training stages. Objective The purpose of this study was to describe and compare the anthropometric profiles of Spanish male and female beach volleyball players at different levels of competition in relation to sports performance. Methods The sample comprised 150 players participating in the 2011 Spanish Beach Volleyball Championships (Under 19, Under 21, and Senior categories). Using the ranking provided by the Royal Spanish Volleyball Federation, the subjects were distributed by performance level (level 1: players ranked first to fourth; level 2: players ranked fifth to ninth; and level 3: players ranked tenth to seventeenth). The study comprised a group of male players, with 18 level 1 ( M1 ), 39 level 2 ( M2 ), and 22 level 3 players ( M3 ), and a group of female players, with 18 level 1 ( F1 ), 41 level 2 ( F2 ), and 12 level 3 players ( F3 ). Results The top level male sample ( M1 ) had a significantly lower average age (19.33 years) than the men’s international elite players (30 years). The top Spanish players of both genders had much lower values for height and body weight than the international elite players. Conclusions Height and fat component are responsible for the differences between top and lower level beach volleyball players, for both men and women. Moreover, as the level of performance increases, players are taller and have a lower fat component. In view of the data observed in this study, the talent selection process in Spanish beach volleyball should aim to select taller individuals than at present.

title: CARDIORESPIRATORY RESPONSES TO ISOKINETIC EXERCISE IN PATIENTS WITH CORONARY ARTERY DISEASE

description: ABSTRACT Introduction Exercise training using an isokinetic dynamometer is an alternative for improving muscle strength in patients with coronary artery disease (CAD). Few studies have shown metabolic and cardiorespiratory responses to submaximal isokinetic exercises in patients in cardiac rehabilitation programs. Objective To describe cardiorespiratory responses at two intensities of isokinetic exercise. Additionally, we compared the cardiorespiratory responses of isokinetic exercise with data from the incremental cardiopulmonary exercise test (CPET). Methods Eight individuals with CAD (61.7 ± 6.6 years) performed the following tests: 1) CPET on a treadmill; 2) Peak torque test (five repetitions) and fatigue resistance test (20 repetitions) of knee flexion-extension at angular speeds of 120°/s and 180°/s; 3) Two sets of 20 repetitions were performed at 30–40% (low-intensity, LI) and 50–60% (moderate-intensity, MI) of peak torque at angular speeds of 120°/s and 180°/s, using an isokinetic dynamometer. During the exercises, the individuals were connected to an expired gases analyzer with simultaneous monitoring of the electrocardiogram trace, heart rate (HR), oxygen consumption (VO2), carbon dioxide production, and minute ventilation (VE). The differences (∆) between the peak measurements during exercises and the baseline values were calculated. Results Both LI and MI produced cardiorespiratory responses below the anaerobic threshold (82.8 ± 8.1% of HRmax and 74.4 ± 9.6% of VO2peak) compared to the CPET data ( P &lt; 0.01). MI showed higher ∆ HR (9.8 ± 5.5 vs. 6.3 ± 4.6 bpm; P = 0.01), ∆ rate pressure product (3015 ± 2286 vs. 1957 ± 1932 mmHg·bpm; P = 0.01), and ∆VE (10.2 ± 6.2 vs. 6.9 ± 7 L·min-1; P = 0.03) than LI at the angular velocity of 180°/s. Conclusion These results suggest that this isokinetic exercise protocol may be used as a strategy for cardiac rehabilitation programs in patients with CAD. Level of evidence IV; Case series.

title: PREVALENCE AND FACTORS ASSOCIATED WITH INJURIES IN RECREATIONAL RUNNERS: A CROSS-SECTIONAL STUDY

description: ABSTRACT Introduction The increased number of people who choose running as a form of exercise has been associated with a higher prevalence of musculoskeletal injuries. Objectives To determine the prevalence and the factors that could be correlated with injuries among amateur runners in Recife, in the State of Pernambuco (PE), Brazil. Methods An observational, cross-sectional study, in which 300 (three hundred) amateur runners answered a social demographic questionnaire, as well as questions about training characteristics, footstrike and landing pattern, and history of running injuries. The data were analyzed by descriptive statistics, the student-t test to compare means, and the Chi-squared to compare prevalences. Results The prevalence of injuries amongst runners in Recife-PE was 58.5% (n= 175), the knee being the most commonly injured site (37.3%). In both groups - runners with and without injuries – there was a higher number of male runners, with 72.4% and 72.6% respectively. There was no difference in relation to the weekly frequency of running between the groups (p&lt;0.63). However, runners with a history of injuries ran around 7 kmh a week more than the runners without injuries (p&lt;0.03). A neutral footstrike (F=0.87; p=0.99) and hindfoot landing (F=4.13; p=0.90) were the most reported running patterns in both groups. It was found that wear was the main criterion used for changing running shoes in both groups (F = 8.35, p = 0.4). Conclusion There was a high prevalence of musculoskeletal injuries among amateur runners in Recife-PE. Among the factors associated with the injuries, one variable was significant: a higher weekly volume of training. Level of evidence II; Study type: Cross-sectional study.

title: INFLUENCE OF THE RELATIVE AGE EFFECT ON HEIGHT, MOTOR PERFORMANCE AND TECHNICAL ELEMENTS OF OLYMPIC VOLLEYBALL ATHLETES

description: ABSTRACT Introduction The Relative Age Effect (RAE) refers to the chronological age difference that occurs between athletes of the same age category, which can benefit individuals born in the first two quartiles of the year. This phenomenon is commonly studied in team sports, yet the results are still inconsistent, especially in volleyball. Objective This study analyzed the distribution of the number of births per quartile of Olympic volleyball athletes and whether this would influence anthropometric/motor variables and technical elements. Methods The sample consisted of 116 male athletes who scored during the Rio 2016 Olympics. For data analysis, we identified each athlete’s quartile as well as data on height, attack and defensive (or block) range, and respective scores during the games. The Chi-square test was then used to verify interquartile distribution. To assess the normality of the other variables, we conducted the Kolmogorov-Smirnov test. Once accepted, one-way ANOVA was performed with the Bonferroni post-hoc test to verify significance between quartiles. A significance level of p≤0.05 was adopted. Results There was no significant difference in the distribution of athletes between quartiles (p = 0.74). When comparing the other variables in terms of the athletes’ trimester of birth, we did not observe any significant difference between height (p = 0.79), attack (p=0.59) and defensive range (p=0.07), and in the scores for serving, attacking and blocking between quartiles either. Conclusion The Relative Age Effect was not observed in Olympic volleyball athletes, therefore this phenomenon is not related to the athletes’ performance. This shows that other possible variables may influence the development of these athletes, discarding the relative age phenomenon. Level of Evidence III; Retrospective and Comparative Study.

title: ELECTROLYTE CHANGES RELATED TO MUSCLE PAIN AFTER RESISTANCE EXERCISES

description: ABSTRACT Introduction Resistance exercises (RE) performed at high intensity cause an inflammatory response and electrolyte abnormalities in blood plasma. Objectives To study the plasma electrolyte changes resulting from a high-intensity session of RE in untrained volunteers, and to correlate these with delayed onset muscle soreness (DOMS). Methods Twenty volunteers, aged 26.9 (±4.4) years, underwent an RE session. The workout (leg extension, squat and leg press) consisted of four sets of 10 maximum repetitions. Electrolytes (Na+, K+, Ca2+ e Mg2+) were evaluated before the training (baseline), immediately (0 min), and 30 minutes after the RE. The DOMS was assessed 24 hours after the sessions. Results The Na+ increased immediately after the RE and returned to normal after 30 min (p&lt;0.001). After 30 min, K+ increased compared to baseline levels and immediately after the RE (p&lt;0.001). Ca2+ and Mg2+ levels did not change throughout the study. Changes in Na+ and K+ levels were correlated immediately (r=-0.511; p=0.021) and 30 min (r=-0.455; p=0.049) after RE. Plasma concentrations of Na+ 0 min were correlated (r=-0.520; p=0.018) with the DOMS. Conclusion High-intensity RE in untrained volunteers leads to changes in plasma concentrations of Na+ and K+. Na+ concentrations immediately after RE were related to DOMS; individuals that presented smaller alterations in this electrolyte reported more muscular pain. Level of evidence II; Diagnostic Studies - Development of diagnostic criteria on consecutive patients (with universally applied reference “gold” standard).
