title: Validation of predictive equations for basal metabolic rate in eutrophic and obese subjects

description: Prediction equations for basal metabolic rate (BMR) continue to be the most common clinical tool for diet prescription; however, the values estimated may differ from those measured by indirect calorimetry (IC), especially in obese subjects. The objective of this study was to determine the BMR of obese and eutrophic subjects by IC, and to compare the results obtained with those estimated by prediction equations in order to identify whether differences exist between predicted values and those measured by IC. Forty men aged 18 to 30 years were evaluated; of these, 20 were grade 1 obese and 20 were eutrophic. The agreement between the prediction equations and IC was evaluated using Bland-Altman (1986) plots. The results showed a variation between the prediction equations and IC of -19.6% to -91% in obese subjects and of 4.2% to 4.4% in eutrophic subjects. In both groups, the Mifflin-St. Jeor equation (1990) was the most accurate, with a difference of -9.1% compared to IC in obese subjects and of 0.9% in eutrophic subjects. This study indicates the Mifflin-St. Jeor equation to be the most adequate to estimate BMR. However, it is important to measure the BMR of obese subjects more accurately and safely in order to establish the best intervention based on physical exercise and healthy eating

title: Relative age effect on anthropometry, biological maturation and performance of young soccer players

description: Abstract The study examined the presence of the relative age effect (RAE) and association between birth quartile and anthropometry, biological maturation and physical and technical performance of young Brazilian soccer players. The sample included 119 male players, 74 of U-15 category and 45 of U-17 category, which were divided into quartiles according to the birth year. Biological maturation was assessed using the method of skeletal age of Fels. Anthropometric measurements included body weight, stature and subcutaneous adiposity. Physical fitness assessment included strength tests in the lower limbs, speed, aerobic endurance and anaerobic power. Technical skills included ball control, dribbling and kicking accuracy. Overall, 65.5% of soccer players were born on the first half of the year (c2= 8.069, p = 0.04); however, in the analysis by category, there was no significant difference in the distribution of birth dates for quartile when compared with the reference population (U-15: c2=6.322, p=0.10; U-17: c2=2.339, p=0.50). MANCOVA revealed no significant differences between anthropometry, biological maturation and physical and technical performance in both competitive categories. These results suggest that there is a higher proportion of young Brazilian soccer born on the first months of the year, but that RAE does not necessarily constitute an advantage under the anthropometric, physical and technical standpoint. The process of biological maturation of individuals should be considered by coaches in the selection of athletes.

title: Effect of the number of sets on acute cardiovascular responses during stretching exercise

description: Abstract Few studies have investigated the effects of manipulating variables of stretching exercise prescription on acute cardiovascular responses. The objective of this study was to compare the acute responses of heart rate, blood pressure and double product before, during and after four sets of passive static stretching during unilateral hip flexion. The sample consisted of 16 adult men aged 18 to 27 years (22±2.8 years) with no experience in flexibility training. The cardiovascular variables were measured by photoplethysmography with continuous recording for 5 minutes at rest, during exercise and 10 minutes after stretching. A difference was observed in all variables (p&lt;0.05) when resting and post-exercise values were compared to exercise values. There was only an increase in blood pressure values between sets. Systolic blood pressure was increased in the third set compared to the first [set 1 = 136 mmHg (±9.4); set 3 = 145 mmHg (±9.7)] and diastolic blood pressure was increased in the second set compared to the first [set 1 = 79 mmHg (±6.7); set 2 = 84 mmHg (±9.1)]. Hypotension was not observed post-exercise. It was concluded that the stretching sets have a cumulative effect on systolic and diastolic blood pressure responses, but not on heart rate. However, the stretching protocol produced no hypotensive effect after exercise.

title: What is the intensity of exercise sessions of a physical exercise program for older adults?

description: Abstract The objectives of this study were to describe and determine the intensity of sessions of a physical exercise program (PEP) for older adults developed within the primary healthcare network of Florianópolis, and to compare the intensity of the sessions between groups using three cutoffs. Eight sessions involving 31 older adults divided into groups I and group II were analyzed. The total time spent during the sessions was considered. Intensity was measured with a triaxial accelerometer and classified according to three different cutoffs. Sociodemographic data, perceived health status, functional fitness, nutritional status and physical activity level at the beginning of the program were also evaluated. The majority of older adults was insufficiently active, was overweight, had low functional fitness, and reported that their health status did not impair physical activity. The mean time spent in moderate physical activity ranged from 1.4 and 16.3 min in group I and from 6.6 and 23.2 min in group II, with the difference being significant. The mean time spent in sedentary activities was 18.7 and 20.5 min for groups I and II, respectively. The findings suggest that the PEP sessions mainly consisted of light or sedentary activities and that the short time spent in more intense activities might be related to the characteristics of the group and to the teaching method adopted by the professionals.

title: Functional fitness in older women from southern brazil: normative scores and comparison with different countries

description: Abstract Functional fitness loss during aging may compromise the quality of life and independence of older subjects. It is important to evaluate and diagnose the functional fitness of the elderly population. This study proposed normative functional fitness scores for a sample of elderly women from southern Brazil and compared values to their counterparts in the US, Extremadura (Spain), Taiwan (China) and Spain. The study sample consisted of 1,783 older women aged 60.0 to 84.9 years (mean 68.7 years; standard deviation 6.3 years) who performed the proposed motor tests of the "Senior Fitness Test" for functional fitness in older women. The percentile values specific to each age group were calculated based on the seven functional fitness components: body mass index, 6-minute walk, arm curl, 30-s chair stand, chair sit-and-reach, backscratch, and 8-feet up-and-go. The non-parametric binomial test compared the 50th percentile value of Brazilian older women with those from other countries. Older women´s performance in the functional capacity tests decreased across age groups. The mean BMI varied among age groups from 29.11 to 26.76 kg/m2, 6-minute walk from 572.94 to 486.95 m, arm curl from 17.51 to 15.11 repetitions, 30-schair stand from 15.62 to 14.30 repetitions, chair sit-and-reach from 1.01 to - 0.47 cm, back scratch from -4.92 to -10.52 cm and 8-feet up-and-go from 5.96 to 6.83 sec. Functional fitness scores among older women in different countries differed significantly. However, the direction and magnitude of differences were specific to the functional fitness component. Significant differences were observed in the normative scores, suggesting that the use of international normative scores in Brazilian older women may underestimate or overestimate potential functional limitations.

title: Biomechanical analysis of the contact phase in drop jumps performed in water and on dry land

description: Abstract Plyometric training in the aquatic environment has been used as way of reducing loads through the action of buoyancy. However, little is known about the biomechanical characteristics of plyometric exercises in water, which can assist in the prescription of training in this environment. This study aimed to analyze the vertical component of the ground reaction force and contact duration of drop jumps (DJ) performed on land and at hip level water immersion. Participants were 22 male athletes (19.1 ± 3.7 years), who performed three maximum DJs in water and on dry land. Peak force and duration of braking and propulsion sub-phases of the DJ contact were analyzed with the use of two underwater force platforms, a 2-D waterproofed electrogoniometer, acquisition systems ADS2000-IP and TeleMyo 2400TG2, and a signal synchronizer. The effect of immersion was investigated through comparison tests for dependent samples (p &lt;0.05). In water, the following results were observed: (a) reduction of 41.8% (p &lt;0.001, d = 2.24) and 23.8% (p &lt;0.001, d = 1.50) of peak forces during braking and propulsion sub-phases respectively; and (b) increase of 41.8% in the braking (p &lt;0.001, d = 1.41) and 12.3% in the propulsion contact times (p = 0.006, d = 0.75). The aquatic environment can be an alternative when one aims to reduce the load during the DJ contact; however, the longer duration increasing of contact sub-phases in water at hip immersion may compromise the proper functioning of the stretch-shortening cycle in water.

title: Leisure-time physical activity and associated factors among adolescents of Pernambuco, Brazil: From 2006 to 2011

description: Abstract Leisure-time physical activity (LTPA) has important implications in promoting physical activity among young people. The present study aimed to analyze variations occurred in the 2006-2011 period in LTPA and associated factors among high school boys and girls in the state of Pernambuco, Northeastern Brazil. A cross-sectional school-based and statewide survey was conducted in 2006 (n = 4,207) and 2011 (n = 6,264), and samples of adolescents (14-19 years) were compared. Data were collected through a questionnaire. The practice of LTPA was obtained by the question “Do you perform regularly, some kind of physical activity in your free time?” Poisson regression was used (confidence interval (CI) 95%) in crude and adjusted analyses stratified by gender. From 2006 to 2011, there was stability in the proportion of adolescents practicing LTPA both among boys (77.5% versus 78.9%) and girls (51.2%, versus 54.0%). The weekly frequency of physical education classes was directly associated with LTPA both in girls and boys, regardless of the survey year. Age, marital status, grade and computer use were significantly associated with LTPA, but there were distinctions between genders and surveys. In conclusion, there was a temporal variation between 2006 and 2011, but the reduction or increment in LTPA practice varied according to stratification of subgroups of adolescents. In general, physical education class was a factor that remained associated with LTPA in the investigated period.

title: The influence of technical skills on decision making of novice volleyball players

description: Abstract The aim of this study was to verify the influence of the technical skills level on the decision making of novice volleyball players on service, reception and set actions. The sample was composed of 80 novice athletes of school volleyball teams of both sexes. Based on the results from the Volleyball Skills Test Battery, the sample was divided into three groups: low, intermediate and high technical level, by means of One-Way ANOVA. The intermediate group was excluded from further analyses. Decision making was assessed with the Game Performance Assessment Instrument (GPAI). For data analysis purposes, the independent student-t test was used, adopting significance level of p≤0.05. The results showed that players with low skill level in service and set actions also had lower performance on the decision-making test when compared to players with high technical level. On the other hand, in the reception action, no differences were found among groups. It was therefore concluded that the technical level seems to influence the decision making in service and set actions in novice volleyball players.

title: Tactic determinants of game practiced by middle attacker in men’s volleyball

description: Abstract Among volleyball skills, spike is responsible for the highest number of scores, and the first tempo of attack is related to the higher incidence of score a point, by hindering the defensive opponent’s action. However, most of the studies show general results and do not specify the conditions and constraints of each attack zone. Thus, the aim of this study was analyzing the offensive game (complex I) performed by the middle attacker at the 2014/2015 National men’s Brazilian Championship (Superliga). The sample was composed by 142 games of 12 teams, totaling 5350 receptions, setting and spikes actions. The results showed that the middle spikes occurred mostly after receptions A and B, being the most frequent attack scoring point as well as the most powerful one. Moreover, the relationship between the reception effect and setting effect was observed, showing that the best receptions influenced the setting type and the attack effect. Therefore, the middle attack had effective effect in the winning score, since it decreased the chances of opponent’s defense, due to the reduced time to defensive organization. Finally, the situational constraints delimited the middle attacker actions. Based on the above, we suggest that future studies should restrict the analysis conditions and situational constraints of each specific game situation.
