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.

This review aimed to compile the evidence on PA and clinical outcomes of people receiving a positive diagnosis of covid-19. Systematic review. The search was performed in five databases: EMBASE, MEDLINE via PubMed portal, Scopus, SPORTDiscus via EBSCO platform, and Web of Science. In addition, the “gray” literature was searched through Google Scholar and medRxiv published between January 2020 and July 2022. Studies were assessed for risk of bias, with the extraction of relevant data. Our search revealed a total of 10,028 studies. After applying the eligibility criteria 32 studies were included. Thirty-one studies were at low to moderate risk of bias. Physically active individuals, who were diagnosed with covid-19, presented attenuation of clinical outcomes, such as decreased risk of hospitalization, recovery time, number of symptoms, severity, and ICU and death when compared to individuals with low levels of PA or classified as sedentary. Physically active individuals when diagnosed with covid-19 may have decreased risk of several clinical outcomes related to covid-19, including but not limited to hospitalization and number of symptoms. Public health authorities should develop strategies and initiatives that promote safe PA environments to improve the clinical prognosis of people diagnosed with covid-19.

This study investigated the acute and chronic effects of training load on vertical jump height, agility, and recovery status in elite male volleyball players. Eleven athletes' internal load was monitored over two 3-week periods, with external load quantification and recovery status assessed in weeks 3 and 7. Countermovement jump and agility tests were conducted pre- and post-training sessions. Results showed higher training load in the first period compared to the second, influencing motor performance, with better outcomes observed in the second period. No negative acute effects on motor performance were found; two sessions showed post-session CMJ improvement, potentially influenced by jump frequency and quantity within those sessions. Periods of high or reduced TL impacted motor performance, specifically vertical jump height and agility. Vertical jump results proved sensitive to TL fluctuations, providing insights into training status, recovery, and motor performance. Reducing TL strategically during the season facilitated physical recovery and positive motor performance adaptations. This suggests managing training load strategically can optimize performance and recovery in elite volleyball players.

We monitored fatigue and stress using heart rate variability and session rating perceived exertion in trained athletes performing a single bout of functional-fitness training workout. Also, we verified the association between heart rate variability and session rating perceived exertion with well-being. In the first week of tapering, eleven national athletes (age: 25.7 ± 3.3y; body mass index: 27.7 ± 2.8 kg·m-2; training history: > 4y) participated in this study. Heart rate variability was analyzed basal, before and after the experimental protocol. Session rating perceived exertion was analyzed after the experimental protocol, and after the assessments, the association between them and well-being was performed. Repeated measures of ANOVA were performed to compare condition x time, and Pearson correlation was used to analyze the associations. Heart rate variability decreased its values after the training workout (ηp2=11.5, p0.05). This study did not support the idea of a significant relationship between objective/subjective, physiological assessments and well-being in one bout of training workout. Functional-fitness coaches and athletes should know the limited evidence about objective/subjective assessments and well-being.
