PERCEPÇÃO SUBJETIVA DA DOR MUSCULAR DE DUAS EQUIPES FEMININAS DE VOLEIBOL DA INICIAÇÃO
Abstract
The objective of the study was of determine the level of the muscle soreness of a female team under 16 and under 14 of the volleyball. The sample was composed of same team that competed in the 2nd Phase of the Grand Prix. Both teams competed in four games and after these matches were presented the muscle soreness scale, this scale was presented in the period of 12 hours after the game. The Friedman Anova did not detect statistical difference (p>0,05) of the muscle soreness of the team under 16 and under 14. The Mann Whitney U test, compared the value of the muscle soreness of the under 16 versus the under 14 in the same time period, and did not find statistical difference (p>0,05). The new statistic did not find statistical difference in the same analysis practiced by significance p. Only a R of the under 16 had statistical difference, internal load of the game 3 versus muscle soreness after the game 3 (R = 0,88, p = 0,0002). In conclusion, the muscle soreness of two female volleyball teams of young players was similar.

Background: The importance of vertical jumps has been extensively recognised in sports. Furthermore, the main indicator of success in vertical jumps is the attained height, however, there is lack of knowledge on how the eccentric and concentric force–time curve variables affect the jump height. Objective: The objective of this study was to assess the relationships between eccentric and concentric variables of the force–time curve and jump height in youth volleyball players. Methods: Twelve elite volleyball players (male, Iranian national youth volleyball players, 17±0.7 years) have participated in this study. The correlations between the force–time variables, including the peak force, relative peak force, peak power, average power, relative peak power, peak velocity, and modified reactive strength index, of the eccentric and concentric phases and jump height have been assessed based on Pearson’s correlation coefficient. Results: Results showed that the average power (r=0.7, p=0.034), relative peak power (r=0.75, p=0.029) and peak velocity (r=0.98, p=0.004) of the concentricphase and modified reactive strength index (r=0.83, p=0.014) significantly correlated with the jump height. Conclusion: relative peak power and average power of the concentric phase are shown to affect jump height in young volleyball players, whereby the vertical jump is their integral part. Based on the study’s outcomes, conditioning coaches are advised to emphasise the development of relative and maximal powers in specific and individualised training program.
Introdução:
No voleibol, o salto vertical é considerado um elemento de extrema importância no treinamento, pois é necessário durante as ações de levantamento, saque, bloqueio e ataque, condicionando a obtenção de importantes vantagens nas ações ofensivas (ataque) e defensivas (bloqueio), elementos fundamentais para a conquista dos pontos no jogo.
Objetivo:
Analisar a influência do salto vertical na quantificação da carga de treinamento no voleibol por meio do método da percepção subjetiva do esforço (PSE) da sessão.
Métodos:
Participaram do estudo 15 atletas do sexo masculino de uma equipe de voleibol. Foi realizada a quantificação dos saltos e da PSE de 30 sessões de treinamento.
Resultados:
Na análise por posição, a PSE apresentou correlação positiva com o número de saltos e se mostrou mais forte nos opostos (r = 0,44; p = 0,001; n = 57), seguida pelos ponteiros (r = 0,34; p < 0,001; n = 109) e centrais (r = 0,18; p = 0,03; n = 141).
Conclusão:
Conclui-se que o salto vertical de ataque exerce maior influência no valor final de PSE apontado pelos atletas nas sessões de treinamento.
The purpose of this study was to investigate the possible arm swing effect on the biomechanical parameters of vertical counter movement jump due to differences of the compliance of the takeoff surface. Fifteen elite male beach-volleyball players (26.2 ± 5.9 years; 1.87 ± 0.05 m; 83.4 ± 6.0 kg; mean ± standard deviation, respectively) performed counter movement jumps on sand and on a rigid surface with and without an arm swing. Results showed significant (p < .05) surface effects on the jump height, the ankle joint angle at the lowest height of the body center of mass and the ankle angular velocity. Also, significant arm swing effects were found on jump height, maximum power output, temporal parameters, range of motion and angular velocity of the hip. These findings could be attributed to the instability of the sand, which resulted in reduced peak power output due to the differences of body configuration at the lowest body position and lower limb joints' range of motion. The combined effect of the backward arm swing and the recoil of the sand that resulted in decreased resistance at ankle plantar flexion should be controlled at the preparation of selected jumping tasks in beach-volleyball.
O objetivo da pesquisa foi de verificar a confiabilidade da escala de dor muscular do voleibol em uma equipe masculina do voleibol master. A pesquisa foi composta por uma equipe masculina do voleibol master (n = 10) que competiu o Campeonato Carioca Master de 2016. A escala de dor muscular do voleibol foi elaborada por Marques Junior, Arruda e Nievola Neto (2016). A confiabilidade da escala de dor muscular do voleibol pelo r intraclasse não teve nenhum resultado com diferença significativa (p>0,05). O teste Kappa identificou somente uma concordância moderada (k = 0,45, p = 0,002) e o método Bland e Altman a concordância foi baixa. Em conclusão, a escala de dor muscular do voleibol merece novos estudos para verificar a confiabilidade desse instrumento para o voleibol master.
ABSTRACT
Reliability of the face scale of the subjective perception of the muscle soreness of the physical effort of the volleyball: a study in the master volleyball
The objective of the research was to check the reliability of the muscle soreness scale of the volleyball in a men`s team master volleyball. The research was composed by a men`s team master volleyball that competed the Carioca Master Championship of 2016. The muscle soreness scale was elaborated by Marques Junior, Arruda e Nievola Neto (2016). The reliability of the muscle soreness scale of the volleyball by intraclass r had no result with significant difference (p>0,05). The Kappa test identified only a moderate agreement (k = 0,42 and 0,002) and the Bland and Altman method the agreement was lower. In conclusion, the muscle soreness scale of the volleyball deserves others studies to check the reliability of this instrument for the master volleyball.
The objective of the study was to detect in a women`s volleyball team under 14 the type of interval – active or passive, that decreases more the subjective perception (SP) of the muscle soreness of the volleyball player. The female team under 14 of the research disputed the championship 1 and 2. The scale of Foster et al. (2001) was used to determine the internal load physical effort of the volleyball game. The scale monitored the muscle soreness of the players was the face scale of the physical effort of the volleyball. In the championship 1 the team practiced the passive interval and in the championship 2, the team performed the active interval. The Shapiro Wilk test detected no normal data of the time in minutes of each sets, of the internal load physical effort of the volleyball game and of the SP of the muscle soreness. The Kruskal Wallis Anova did not detect significant differences time in minutes of each sets and of the SP of the muscle soreness of the passive internal versus active internal. The Friedman Anova did not detect significant differences in the internal load. In conclusion, the active interval can be beneficial to reduce the SP muscle soreness.
The objective of the research was to check the reliability of the faces scale of the subjective perception effort adapted Foster in a men`s team master volleyball. The research was composed by a men`s team master volleyball that competed the Carioca Master Championship of 2016. The reliability of the faces scale of the subjective perception effort adapted Foster by intraclass correlation has a r good (r = 0,75, r = 0,84, r = 0,89 e r = 0,85) and a r medium (r = 0,70) (p≤0,05). The Kappa test showed no significant difference (p>0,05) and the Bland and Altman method the predominant agreement was lower. In conclusion, the scale this study deserves others studies to check the reliability of this instrument for the master volleyball.
The objective of the study was to detect a type of interval – active or passive, that reduces more the subjective perception (SP) of the muscle soreness. The sample was composed by a double female volleyball that competed in three competitions of the Brazilian Circuit 2015/2016. The face scale of the SP of the muscle soreness of the physical effort of the volleyball was presented before and after the games. The face scale of SP effort adapted of Foster and SP difficulty scale of the opponent were presented after the game. The protocol of the active aerobic interval used in the qualifying and in the 4th phase followed the following guidelines: intermittent effort (light run and walk) in the distance of 10 meters with a stimulus of 3 minutes. The intensity of the active interval was monitored by the talk test (level 1 = comfortable speak). But in the 5th phase of the Brazilian Circuit occurred the passive interval. Friedman Anova did not detect significant difference in the internal load of the game of each championship, X2 (2) = 6, p = 0,06. Friedman Anova did not detect significant difference SP difficulty scale difference of the opponent of each championship, X2 (2) = 6,1, p = 0,06. Friedman Anova did not detect significant difference SP of the muscle soreness various moments of the different competitions, X2 (18) = 28,14, p = 0,06. In conclusion, the active aerobic interval seems to decrease the SP of the muscle soreness.
The objective of the review article was to explain methods to accelerate the reduction of the delayed onset muscle soreness (DOMS) and present the advantages and disadvantages of each procedure. The methods to accelerate the reduction of the DOMS after physical effort were composed by the following techniques: cryotherapy, active recovery and supplementation of some substances. In conclusion, there are several methods of reduce the levels of the DOMS, It is necessary study of the scientists to detect the best method to end with this type of fatigue in accordance with the type of sport or as modality of the physical activity.

ABSTRACT Personal training: relevant factors for contracting the service The objective was to verify the level of importance attributed by the clients of personalized training (PT) to different relevant factors when contracting the service. Thirty-nine individuals (14 men and 25 women, 42.2 ± 13.8 years-old) enrolled in a PT program in the city of Praia Grande, SP, who had a training routine for at least one month, participated in the study. Subjects were asked to answer a questionnaire adapted from previous publication that aimed to identify the level of importance attributed by the volunteer to different factors relevant to the contracting of the PT service. The results were presented in an average percentage of importance. The technical-specific knowledge was the most relevant factor at the time of contracting the service, presenting 100% of relevance. Following, in decreased order of importance came professional attitude (98.3%), attendance (97.4%), curriculum (96.6%), physical evaluation (94.9%), partnerships with other professionals (80.3%), indications (79.4%), training sessions (58.9%), physical appearance (20.5%), price (20.5%), and participation in sporting events (15.4%). It is concluded that the PT client values more factors related to quality and safety of the service in relation to logistics, cost and other false motivating factors.
