Fitness Levels

Limited data are available on whether different physical fitness levels are associated with injury severity in contemporary dancers. The aim of this study was to investigate this association in female dancers. Five professional contemporary dancers and 11 dance students in pre-professional training volunteered (n = 16). All participants underwent selected fitness assessments (anthropometry, flexibility, muscular power and endurance, aerobic capacity) and completed a seven-item recall questionnaire about their last 12-month injury history. Pearson's coefficients detected significant negative correlations between the total number of days off due to injuries and standing vertical jump (r = –0.66; p = 0.014). Backward regression analysis also revealed that days off due to injuries was best predicted from standing vertical jump performance (p = 0.014). Results suggest that a reduced level of lower body muscular power is associated with increased severity of injuries in female contemporary dancers. More research using appropriate methodological designs, such as sample size calculations and randomization and the use of contemporary dance movements only, is needed to investigate the effects of physical fitness levels on injury severity in contemporary dance.

High Flexibility

This study aimed to assess the effect of high and low levels of flexibility on key performance indicators of volleyball performance. Eighty-four volleyball players (n=84; mean±SD; decimal age: 16.57±1.51; height (cm): 176.23±8.77; body mass (kg): 66.14±11.79) were selected for the study. The design of the study was cross-sectional and to measure selected variables i.e. agility, lower body muscular power, and acceleration speed; 6×10 m shuttle run, countermovement jump (with arm swing) test and 20 m sprint test (standing start) were used. To measure the flexibility level of the players, sit and reach test was used. Shapiro-Wilk normality test was conducted to check the distribution of data and the Levine test was applied to check homogeneity of the variance in data. Participants were divided into two groups i.e. High Flexibility Group (HFG) and Low Flexibility Group (LFG) using k-means cluster analysis and independent t-test was applied to find the differences between HFG and LFG. The level of significance was set at p < 0.05. Results showed statistically significant difference between HFG and LFG in agility, acceleration speed and lower body muscular power and, based on the results, it was concluded coaches should include flexibility training in the regular training programme. The results obtained supported the rationale that baseline flexibility may influence the performance of volleyball players. <p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0778/a.php" alt="Hit counter" /></p>

Practice Time

Padel is widely practiced racket sport, although there is scanty data comparing competitive levels and differences between the sexes. Physical fitness of padel players was compared, according to sex and level. The research involved 35 people (age = 29.6 ± 2.9 years, practice = 6.8 ± 4.9 years), 13 of the first, 15 of the second and 7 of the third category. Aerobic power (PAM) with Yo-YoIR1, agility with handball agility specific test (HAST), muscular power with vertical jump and 3kg medicineball throw, and handgrip endurance strength (HES) with dynamometer were measured. The variables PAM, HAST, vertical jump, throttle and FIPM were significantly different between genders. In addition, in the male category, players in the upper category had lower heart rate scores after Yo-YoIR1 as well as distance traveled, throttle and FIPM maximum, while in females the superior category was better in the variables distance traveled in Yo-YoIR1 and vertical jump. On the other hand, in both sexes, players of superior categories presented greater time of practice. Amateur padel players with a higher competitive level do not present higher physical fitness, but present longer practice time.

Anaerobic Testing

Muscular strength and anaerobic power could be assessed by single and multiple vertical jump testing procedures. Anaerobic capacity measured by vertical jump testing is highly correlative with athletic performance, as compared to other anaerobic testing procedures. The most frequently used protocol with contact mat or force platform consists of single jump (i.e. squat jump, drop jump, countermovement jump) and serial jump testing with different duration. Measured variables include jump height and duration along with absolute and relative peak muscular power. Several investigators have clearly shown superior jump performance variables in elite athletes as compared to non-elite subjects. Differences obtained could be due to genetic factors and acute or prolonged efects of training regimen.

IntroductionPhysical fitness is a fundamental capability required of military personnel, but studies focusing on longitudinal changes in physical fitness and anthropometrics in soldiers are lacking. The aim was to evaluate physical fitness and anthropometrics in soldiers during their early career.MethodsA 3-year prospective study included 180 male soldiers (baseline age 26±2 years) with measures of a 12 min running test, standing long jump, sit-up and push-up tests, and body mass, height and waist circumference (WC). Baseline data were stratified into tertiles, and the changes within each tertile were analysed using dependent t-tests and analysis of variance.Results12 min running test distance decreased on average by 2% (−54 m), sit-up performance 3% (−1.5 repetitions (reps)/min), push-up performance 4% (−1.9 reps/min) and standing long jump performance 1% (−2.1 cm) over the 3-year period (p<0.05). Both aerobic and muscular fitness decreased consistently among the highest baseline tertile (12 min running test: −70 m, sit-ups: −3.2 reps/min, push-ups: −7.5 reps/min, standing long jump: −5.5 cm; p<0.001), whereas both aerobic and muscular fitness levels were maintained and push-up performance was improved (p<0.05) in the lowest baseline tertiles. Body mass increased on average by 4% (+3.4 kg) and WC by 4% (+3.9 cm) (p<0.001), and these increases were observed for all baseline tertiles (p<0.05).ConclusionsSmall decrements in physical fitness and anthropometrics exist during the early career of soldiers. The changes in physical fitness differed according to baseline fitness levels. The results indicate that support for exercise training may be needed even in a soldier’s early career.

Introdução: O Campo Operacional de Instrução (COI) demanda elevado esforço físico e mental.Objetivo: Avaliar os efeitos das atividades de treinamento militar sobre indicadores de dano muscular periférico, de controle autonômico e de aptidão física em alunos do Núcleo de Preparação de Oficiais da Reserva (NPOR) de Pelotas.Métodos: Este estudo longitudinal, avaliou 18 alunos do curso de formação do NPOR, antes e após uma semana de atividade em COI com exercícios físicos intensos. Mensuraram-se a concentração sanguínea de creatina quinase [CK], os indicadores da variabilidade da frequência cardíaca (VFC) e o desempenho dos participantes em testes de aptidão física. O teste de Shapiro-Wilk foi utilizado para avaliar a normalidade dos dados e os momentos foram comparados com teste t de Student para amostras dependentes e as correlações testadas com a prova de Pearson. O nível de confiança das análises foi de 95%.Resultados: A potência de membros superiores e inferiores diminuiu (p<0,05) e o desempenho em força isométrica máxima de preensão da mão esquerda (p=0,03) e resistência abdominal (p<0,00) aumentaram. Houve aumento na VFC (p<0,01), e tamanho do efeito negativo em todos os casos. Entre as variáveis do domínio do tempo, LF teve tamanho do efeito igual a -0,17 e HF -0,28 (p<0,001). Em [CK] não houve alteração. Houve alta correlação entre decréscimo em potência de membros inferiores (salto vertical com contramovimento) e [CK] (p=0,01).Conclusão: Os resultados em VFC sugerem que as atividades realizadas durante o COI promoveram respostas dos ramos simpático e parassimpático de forma significativa, e indicaram boa saúde cardíaca dos participantes devido ao aumento observado entre intervalos RR. Além disso, a diminuição de potência de membros inferiores (no salto vertical com contramovimento) e níveis de [CK] indicou que diferenças nos valores do desempenho, no salto vertical com contramovimento, pode ser, também, utilizado como marcador não invasivo de dano muscular. Effects of Operational Field of Instruction on Physical Fitness, Muscle Damage Markers and Autonomic Control in NPOR Students of Brazilian ArmyIntroduction: The Operational Field of Instruction (OFI) demands high physical and mental effort.Objective: To evaluate the effects of military training activities on indicators of peripheral muscle damage, autonomic control, and physical fitness in students of the Center for Reserve Officers Preparation (CROP) of Pelotas, before and after an OFI and to examine associations with muscle damage. on trainee students.Methods: This longitudinal study evaluated 18 students of the NPOR training course, before and after one week of activity in IOC with intense physical exercises. The blood concentration of creatine kinase [CK], the indicators of heart rate variability (HRV) and the performance of participants in physical fitness tests were measured. The Shapiro-Wilk test was used to evaluate the normality of the data and the moments were compared with Student's t test for dependent samples and the correlations tested with the Pearson test. The confidence level of the analyzes was 95%.Results: The power of the upper and lower limbs decreased (p <0.05) and the performance in maximal isometric strength of the left hand (p = 0.03) and abdominal resistance (p <0.001) increased. There was an increase in HRV (p <0.01), and size of the negative effect in all cases. Among the variables of the time domain, LF had effect size equal to -0.17 and HF -0.28 (p <0.001). In [CK] there was no change. There was a high correlation between decrease in power of lower limbs (vertical jump with countermovement) and [CK] (p = 0.01).Conclusion: The HRV results suggest that the activities performed during the IOC promoted sympathetic and parasympathetic responses in a significant way and indicated good cardiac health of the participants due to the observed increase between RR intervals. In addition, lower limb power (in vertical jump with countermovement) and [CK] levels indicated that differences in vertical jump performance values with countermovement may also be used as a non-invasive marker of muscle damage. The abstract should not exceed 250 words and must summarize the work, giving a clear indication of the conclusions contained therein. It should be structured. The introduction should contextualize the problem.
