OBJETIVO: O objetivo deste estudo foi comparar o desempenho no teste de potência de membros inferiores e flexibilidade de atletas de voleibol do gênero feminino, categoria sub-16, submetidas exclusivamente ao treino de força com atletas submetidas ao treino de força e flexibilidade.MÉTODOS: As atletas foram divididas em dois grupos. Um grupo realizou o treinamento de força (GTF) e o outro grupo efetuou o treinamento de força e flexibilidade (GTFF). O período de treinamento foi de dois meses. Para a avaliação da potência de membros inferiores e flexibilidade optou-se, respectivamente, pelo teste de salto horizontal e sentar-e-alcançar. Verificou-se a normalidade dos dados através do teste de Shapiro-Wilk. Alicerçado nestes resultados, utilizou-se o Anova two way, com post hoc de Sidak, para duas amostras independentes a fim de identificar o efeito do treino nos testes de salto horizontal e sentar-e-alcançar. O teste de Mann Whitney foi utilizado para verificar a diferença da melhora entre grupos no teste de força, e o teste t independente para verificar a diferença da melhora entre grupos do teste de sentar-e-alcançar.RESULTADOS: Verifica-se que houve diferença entre as médias entre as diferentes avaliações (tempo) no teste de salto horizontal [F(2,48)=10,282; p0,05] e flexibilidade [F(2,48)=10,298; p0,05). No salto horizontal a diferença significativa ocorreu no grupo GTF (p0,05). Na flexibilidade, a diferença significativa ocorreu no GTFF (p0,05). Na comparação entre grupos, o teste de Mann Whitney retornou valor de p=0,924 no teste de força. Não obstante, o teste t independente retornou valor de p=0,106 no teste de sentar-e-alcançar.CONCLUSÃO: Conclui-se que em face a importância da flexibilidade para atletas de voleibol, ainda que a GTFF não tenha apresentado melhora significativa no teste de impulsão vertical, não é possível refutar a utilização do treino de força aliado ao treino de flexibilidade.  ABSTRACT. Effects of different models of strength and flexibility training on the performance of the horizontal jump and sit-and-reach test in volleyball players.OBJECTIVE: This study aimed to compare the performance in the lower limb strength test and flexibility test of athlete of volleyball of the feminine gender, category sub-16, exclusively submitted to the strength training with athletes submitted to the strength training and flexibility training. METHODS: The athletes were divided in two groups. A group carried through the strength training (GTF) and the other group effected the strength training and flexibility training (GTFF). The period of training was of two months. For assessing lower limb strength and flexibility it was opted, respectively, for the horizontal jump test and to sit-and-reach test. It was verified normality of the data through the test of Shapiro-Wilk. Based in these results, Anova two way with post hock of Sidak was used to identify the effect of training in horizontal jump test and sit-and-reach test. For the difference between the initial and final test of each group, the Mann Whitney test was used to identify the difference of the improvement between groups in the strength test and independent test t was used to identify the difference of the improvement between groups of the sit-and-reach test. RESULTS: We found that there was a difference between the different test in the horizontal test [F(2.48)=10.282; p0.05] and sit-and-reach test [F(2.48)=10.298; p0,05). In the horizontal jump test there was a difference in GTF group (p0.05). In the flexibility test there was a difference in GTFF group. In the comparison between groups, the Mann Whitney test returned value from p=0.924 for the performance of the strength test. Besides that, independent test t returned value from p=0.106 for the performance of the flexibility test. CONCLUSION: We concluded that in view the importance of flexibility for volleyball athletes, it is not possible to refute the use of strength training combined with flexibility training.

Back Massage technique combined with holistic aromatherapy treatment can be an effective therapy for postnatal mothers to increasing breast milk production. This study aims to analyze the effect of Miyik-miyikan aromatherapy on back massage. The increase of breast milk production in postpartum mothers can be seen from the baby’s weight gain. This study was conducted at an inpatient Primary Health Center in Denpasar, in June-October to 30 mothers. This study was designed in a quasi-experimental pre-posttest control group with a time series approach. The observation of the baby’s weight gain and breastfeeding satisfaction starts from day 1, day 7, and day 14 after delivery. This study was analyzed using the Kruskal Wallis Test and the Mann Whitney test. The result of the study showed that the Kruskal Wallis test is p <0,05, meaning that there was a difference in breast milk production in the two groups of intervention. Additionally, the Mann Whitney test showed the difference of baby weight on the 7th day to those in the Miyik-miyikan and Cananga group, and on the 14th day in the Cananga, Miyik-miyikan, and Champak group. Thus, the use of Miyik-miyikan aromatherapy on a back massage can be done earlier after delivery

AbstractThe purpose of the present study was to identify the effects of a strength training program combined with specific plyometric exercises on body composition, vertical jump (VJ) height and strength development of lower limbs in elite male handball players. A 12-week program with combined strength and specific plyometric exercises was carried out for 7 weeks. Twelve elite male handball players (age: 21.6 ± 1.73) competing in the Portuguese Major League participated in the study. Besides the anthropometric measurements, several standardized jump tests were applied to assess VJ performance together with the strength development of the lower limbs in an isokinetic setting. No significant changes were found in body circumferences and diameters. Body fat content and fat mass decreased by 16.4 and 15.7% respectively, while lean body mass increased by 2.1%. Despite small significance, there was in fact an increase in squat jump (SJ), counter movement jump (CMJ) and 40 consecutive jumps after the training period (6.1, 3.8 and 6.8%, respectively). After the applied protocol, peak torque increased in lower limb extension and flexion in the majority of the movements assessed at 90°s-1. Consequently, it is possible to conclude that combining general strength-training with plyometric exercises can not only increase lower limb strength and improve VJ performance but also reduce body fat content.

Background: Lactation onset is a term of multiplying breast milk until the release of breast milk for the first time. It is also perceived by mothers as a bit hard breast, inflammed, and full of breast milk or the release of colostrum. Colostrum is the first liquid secreted by breast milk gland since the first day until the fourth day of labour. One of the factors that influences lactation onset is labour methods. Mothers who undergo sectio caesaria surgery will experience pain and prolonged effects of anesthesia compared to mothers with normal labors. Objective: To investigate the difference of colostrum releasing onset in post partum mothers with normal labors and sectio caesaria in Panembahan Senopati General Hospital, Bantul. Method: This study was quantitative with cross sectional design. The number of samples were 80 respondents selected with purposive sampling technique. Study instrument was observational sheets. Data analysis applied Mann-Whitney test. Result: The majority of respondents who had normal labors and sectio caesaria experienced different colostrum onset. In normal labors, the time of colostrum release was 1 day. In sectio caesaria labors, the time of colostrum release was 2 days. The average duration of post partum mothers with normal labors was 13,6 hours and post partum mothers with sectio caesaria was 22,6 hours. The result of Mann-Whitney test was that there was a difference between colostrum release onset of post partum mothers with normal labors and sectio caesaria with p-value of 0,001 (p<0,05). Conclusion: Colostrum onsets were different in normal labors and sectio caesaria labors. Keyword: Colostrum, Normal labors, Sectio Caesaria labors.
