Introduction. The objectives of this systematic review were to identify the volleyball external loads values in the literature and to verify the applicability of different means of quantification and monitoring of these variables during training sessions and matches. Material and methods: This systematic review was produced following the PRISMA statement recommendations, and the search for publications was carried out in the databases PubMed/NCBI, SportDiscus via EBSCOhost, SciELO. 12 studies meet the criteria and were included in this review. Results: The most used tool for quantification, monitoring and evaluation of external loads are video recording and manual or semi-automatic counting of jumps and distance covered and, more recently, the use of inertial measurements unit. The middle blocker has the highest high jump load, outside hitters jump closer to the maximum more often and setters have a high demand of medium height jumps. Conclusions: Match and training jump loads seem to be similar, and sessions that involve block or attack have a higher jump load. In professional male volleyball, training is planned with variation in training loads according to the period of the sea-son and according to the days of the week before and after games.

Objective: Sports injury can occur due to several factors, which makes it extremely difficult to conduct cause and effect studies by controlling and evaluating a specific variable. Common reason for the appearance of injuries is poor physical preparation for the proposed training load, a factor that is more present in high intensity sports. CrossFit has been gaining a great deal of attention in recent years due to its dynamic mix of varied sports. Beginner and intermediary level participants are very common in CrossFit gyms, so the understanding the training effect for this group is very important for healthy practice (aiming for safety and injury rate). Methods: Only original articles were included, between 2000 and 2019 (November), with the search for the word "CrossFit" in nine databases. It was accepted only studies in Portuguese, English or Spanish. Results: After screening, only three studies met the inclusion criteria following Preferred Reporting Items for Systematic Reviews and Meta-Analyses assessment. The most common injury segments in beginner and intermediate practitioners were the shoulder and the knee. There are functional and morphological mechanisms that makes injury become more common, such as life habits and anatomic / physiological body disposition. Conclusion: CrossFit beginners and intermediaries participants demonstrated moderate injury level. Studies with more subjects showed a lower injury level. The most injured segments found were knee and shoulder. According to our results the risk of injury in CrossFit beginner and intermediary participants is acceptable, and discussed in recent published reviews.

Este estudo buscou compreender a situação das academias de ginástica durante a pandemia por COVID-19, através de análises das reportagens de um site de grande circulação. Observou-se sobre o contexto do fechamento e prejuízo das academias; relação cliente, empresa e profissional; consequências no ambiente empreendedor da área fitness; estratégias empregadas pelos profissionais do ramo e reabertura gradual. Após analisar as 246 reportagens selecionadas, foi identificado que São Paulo e Minas Gerais foram os estados mais noticiados, o que pode estar relacionado ao fato de pertencerem à região com maior fluxo de notícias no país. Algumas das alternativas utilizadas pelas academias foram a negociação dos meses de mensalidade pagos como crédito para o período pós isolamento, enquanto outras decidiram suspender o pagamento das mensalidades até que o isolamento fosse relaxado. Também utilizaram como alternativa o atendimento online, atendimento a domicílio, empréstimo de equipamentos e atendimento individual no próprio estabelecimento. Apesar da proposta dessas alternativas, de um modo geral, a suspensão das atividades presenciais provocou prejuízos financeiros. Portanto, considera-se que o processo de recuperação do faturamento perdido será lento.

Zecchin, A, Puggina, EF, Hortobágyi, T, and Granacher, U. Association between foundation strength and weightlifting exercises in highly trained weightlifters: support for a general strength component. J Strength Cond Res 37(7): 1375–1381, 2023—In addition to specific weightlifting exercises (i.e., clean and jerk and snatch), foundation strength exercises (i.e., overhead press, front squat, and deadlift) constitute an integral part of the weightlifters' training regime. The unexamined concept behind this training plan is that foundation strength exercises are associated with clean and jerk and snatch performance, implying the existence of a general strength component. We thus determined the relationship between performance in foundation strength exercises (overhead press, front squat, and deadlift) and weightlifting exercises (clean and jerk and snatch) in weightlifters. Well-trained weightlifters (N = 19, age: 26.8 ± 4.4 years; body mass index: 27.6 ± 2.3 kg·m−2; and training history: 4.6 ± 0.8 years) performed 1 repetition maximum tests (1RM) in foundation strength and weightlifting exercises, over 14 days, in a randomized order. We observed significant correlations in 1RM performance between the overhead press and snatch (r = 0.69), front squat and snatch (r = 0.73), overhead press and clean and jerk (r = 0.67), and front squat and clean and jerk (r = 0.72, all r values: p < 0.01). No significant correlations were found for 1RM performance between the snatch and deadlift or between the clean and jerk and deadlift (r-range: 0.20–0.58; p > 0.05). Stepwise linear regression revealed that 1RM performance in the overhead press and front squat explained 62% of the variance in snatch 1RM performance (F = 5.51; p < 0.04). Overhead press and front squat 1RM performance explained 59% of the variance in the clean and jerk 1RM performance (F = 5.14; p < 0.04). Our results demonstrate the existence of a general strength component between selected foundation strength exercises and weightlifting performance. However, the use of the front squat and overhead press to increase 1RM performance in weightlifting exercises needs to be determined in future research using a different methodological approach (i.e., longitudinal protocols), given that the observed correlations do not necessarily imply causation.
