RESUMO

ABSTRACT This study has evaluated the differences in the physiological and neuromuscular responses in female futsal athletes during a friendly game. Sample comprised six female futsal players (21.8 ± 3.9 years; 57.4 ± 4.1 kg; 159.0 ± 2.7 cm height; 19.0 ± 3.3% body fat and 7.8 ± 1.8 years of practice). Heart rate (HR) was monitored during the whole game. Coutermovement Jump (CMJ), Resistance Explosive Power (REP) lower limb and blood lactate have been evaluated before and after the final of the first and second periods. To compare physiological and neuromuscular variables between the different moments we have used standardized mean difference (SMD), confidence interval (CI = 90%) and the probabilities of differences with clinical relevance. Maximal heart rate (HRmax) was 186.6 ± 10.6 and 185.8 ± 8.3, first and second periods, respectively. There has been a substantial lactate increasing in the moment prior to the start of the game to the final of the first (2.1 ± 0.3 to 6.3 ± 2.3 mmol/L-1, SMD = 5.25 (3.28: 7.21), 100/0/0; most likely) and the second periods (2.1 ± 0.3 to 5.4 ± 1.3 mmol/L-1, SMD = 4.62 (3.19: 6.04), 100/0/0; most likely). Although there has been an increase in blood lactate, the performance of female futsal players was not suppressed during and immediately after a friendly game, suggesting that the neuromuscular system may be restored immediately after the end of the game.


RESUMO O presente estudo testou se existem diferenças, nas respostas fisiológicas e neuromusculares em atletas de futsal durante um jogo amistoso. A amostra foi composta por seis atletas de futsal do sexo feminino (21,8 ± 3,9 anos; 57,4 ± 4,1 kg; 159,0 ± 2,7 cm de altura; 19,0 ± 3,3% gordura corporal e 7,8 ± 1,8 anos de tempo de prática). A frequência cardíaca (FC) foi monitorada durante toda a partida. O salto com contramovimento, resistência de força explosiva de membros inferiores e lactato sanguíneo foram avaliados antes, após o final do primeiro e segundo tempo de jogo. Para comparação das variáveis neuromusculares e fisiológicas entre os diferentes momentos, nós utilizamos as diferenças de médias estandardizadas (DME), intervalo de confiança (IC = 90%) e probabilidades de haver diferenças com relevância clínica. A FC máxima (FCmáx) foi de 186,6 ± 10,6 e 185,8 ± 8,3, primeiro e segundo tempo, respectivamente. Houve um aumento substancial do lactato do momento que antecedeu o início da partida para o final do primeiro (2,1 ± 0,3 para 6,3 ± 2,3 mmol/L-1, DME = 5,25 (3,28: 7,21), 100/0/0; most likely) e segundo tempo (2,1 ± 0,3 para 5,4 ± 1,3 mmol/L-1, DME = 4,62 (3,19: 6,04), 100/0/0; most likely) de partida. Embora tenha ocorrido um aumento do lactato sanguineo, a performance de atletas femininas de futsal não foi suprimida durante e logo após uma partida amistosa, sugerindo que, o sistema neuromuscular possa estar restaurado logo após o término do jogo.

RESUMO

OBJECTIVE: The objective of this study was to compare the effect of 16 weeks of resistance training using different occlusion pressures, followed by 6 weeks of detraining on the muscular strength levels of older women. METHODS: This randomized-controlled trial included 56 recreationally active women (68.8 ±â€¯5.09 years), randomized into 5 groups: 1) Low-intensity with blood flow restriction "High" (LI + BFR_H): with higher occlusion pressure, 2) Low-intensity with blood flow restriction "Low" (LI + BFR_L): with lower occlusion pressure, 3) High-intensity (HI), 4) Low-intensity (LI), and 5) Control Group (CG). Participants completed 16 weeks of resistance exercise training, followed by a 6-week detraining period. Maximal isokinetic torque (N.m) of right and left knee extension (PTRE/PTLE) and flexion (PTRF/PTLF) was measured at pre-training, post-training and immediately following the detraining period. RESULTS: Increased strength was observed in the LI + BFR_H, LI + BRF_L and HI groups post-training compared to baseline in the PTRE (Δ% = 27.2, 15.75 and 13.81%, p < .05, respectively), PTLE (Δ% = 25.2, 18.95 and 30.39%, p < .05, respectively), PTRF (Δ% = 36.7, 22.79 and 34.97%, p < .05, respectively) and PTLF in the groups (Δ% = 35.8, 24.93 and 26.14%, p < .05, respectively). Following the detraining period, the LI + BFR_H, LI + BFR_L and HI groups had a decrease in strength levels, but values did not decrease below baseline level. CONCLUSION: Low intensity BFR resistance exercise increases muscle strength in older women similar to HI, with higher occlusion pressures being more effective. Muscle strength was well preserved following a 6-week detraining period, and although reductions were observed, some preservation of strength can be explained by possible neural adaptations to exercise.

RESUMO

The purpose of this systematic review is to look into how the experience of husbands of women treated for breast cancer is approached in the literature. Between July and August 2015, the databases of PubMed, SciELO and BIREME were searched for papers published in the period January 2005-July 2015; a final sample of 23 papers was defined. The studies listed several negative and positive aspects of the experience, such as financial difficulties, psychological distress, lack of coping skills among family members, social recognition of the role of caregiver, acquisition of new responsibilities and the maturing of family members.
