“…In addition to the goals established by the coach, the internal and external intensity throughout the competition week should be considered to respect the team’s recovery time for the next game [ 7 , 32 , 33 ]. Thus, the training load is higher at the beginning of the week, remains high throughout the week, and decreases at the week ending allowing players to present their best performance on competition day [ 15 , 33 , 34 ]. However, when the weeks have congested games, although there is no difference in physical demand when compared to regular weeks [ 4 ], the accumulation of games affects the well-being of players compared to regular weeks, even with training loads before games being similar between regular and congested weeks [ 35 ].…”

The purpose of the study was to test the within-week variations of the internal and external training intensity outcomes organized by days of the week. An 8-month observational period was conducted during the 2020–2021 season. The training sessions and matches of an elite volleyball team were monitored daily. The data comes from 14 players (two setters, five middle blockers, five outside hitters, and two opposites) of an elite team from the Portuguese 1st League (age: 21.7 ± 4.19 years of age; experience: 6.2 ± 3.8 years; body mass: 85.7 ± 8.69 kg; height: 192.4 ± 6.25 cm; BMI: 23.1 ± 1.40 kg/m2). The CR10 Borg scale was applied daily to measure the training intensity. The rate of perceived exertion (RPE) and the session-RPE were extracted as the internal outcomes. The external intensity was measured using an inertial measurement unit (IMU). The number of jumps, height average of jumps (JHA), minimum jump (MJ), maximal jump (MXJ), range jump (RJ), number of jumps (NJ), and training session density (D) were extracted as external intensity outcomes. The results showed that there was a difference between RPE and S-RPE (F (1.98) = 6.31, p = 0.01, η2 = 0.36, and F (1.73) = 28.30, p = 0.001, η2 = 0.72), as well as JHA and NJ (F (2.14) = 4.76, p = 0.02, η2 = 0.30, and F (1.77) = 4.77, p = 0.02, η2 = 0.30) within the microcycle. When analyzing the correlations between internal and external intensity, it was observed that there was a negative correlation between the Maximum Jump (4, 3, and 1 days before the Match day) (r2 = 0.34, r2 = 0.40, r2 = 0.41, respectively) and the Range Jump (3 and 1 days before the Match day (r2 = 0.33, r2 = 0.38, respectively) with the RPE (4 days before the Match day) and Maximum Jump (5, 4, 3, and 1 days before the Match day (r2 = 0.35, r2 = 0.39, r2 = 0.44, r2 = 0.34, respectively) and Range Jump (5, 4, 3, and 1 days before the Match day) (r2 = 0.34, r2 = 0.35, r2 = 0.40 and r2 = 0.36, respectively) with S_RPE (4 days before the Match day). Such findings show that higher internal intensities are correlated with lower external intensities in sessions further away from the game day. Such results could be an important tool for coaches to reflect, plan, monitor, and execute the training unit according to the temporal distance to the competition.

“…The sport-specific onset of specialization was interpreted considering biological maturation milestones (Lima et al, 2020;Mendes et al, 2021). The biological maturation milestones considered were the age of initiation of the pubertal growth spurt and the age at peak height velocity (PHV).…”

“…The biological maturation milestones considered were the age of initiation of the pubertal growth spurt and the age at peak height velocity (PHV). Information on how the biological maturation milestones were estimated using data from a meta-analysis of growth studies is available elsewhere (Lima et al, 2020;Mendes et al, 2021). The reference age of initiation of the pubertal growth spurt was 9.4 (95% CI 9.0 to 9.8) years, and the reference age at PHV was 11.9 (95% CI 11.8 to 12.0) years.…”

“…It refers to the various temporal aspects of development, including the progression of time over which development occurs, such as an individual's chronological age. In the context of youth sports, however, biological time should be taken into account, given the substantial differences in the timing and tempo of pubertal development among individuals and its impact on physical function, performance, and behavior (Carvalho et al, 2017;Lima et al, 2020;Mendes et al, 2021).…”

The present study used a bioecological approach to examine the influence of personal characteristics (maturity status), process (accumulated deliberate practice), and contextual factors (including age group, competition level, sport type, and state) on the variation of sources of enjoyment among young female athletes. We also explored the effect of the dynamic interactions of time with personal characteristics and process (chronological age, menarche age, and years of accumulated deliberate practice in a specific sport). We considered 243 young female athletes (171 basketball players, and 72 volleyball players) aged, on average, 15.0 years (ranging from 10.1 to 19.7 years). Repeated measures were collected from a sub-sample of 84 athletes (41 basketball players, 43 volleyball players) aged, on average, 14.0 years (ranging from 11.5 to 18.1 years) at baseline, across competitive seasons during the survey period to fully operationalize the bioecological approach. Age group, menarche status, onset of specialization, competitive level, sport, state, and self-reported measures of sources of enjoyment, using the Sources of Enjoyment in Youth Sports Questionnaire (SEYSQ), were recorded. We used Bayesian hierarchical models to model the responses of the players in the SEYSQ. The young female athletes mainly agreed (response 5 in the Likert-like scale) with the statements in each factor of the SEYSQ. There was no variation in the responses by SEYSQ factors associated with process (onset of specialization), person (menarcheal status), and context (age group, sport, competitive level, and state), when considering the cross-sectional data. When aligning the three chronosystems (chronological age, menarche age, and accumulated sport-specific deliberate practice), it was possible to identify the importance of the sport context to the changes in the sources of enjoyment across the development of young Brazilian female athletes between 12 and 18 years. Overall, our findings underscore the necessity of incorporating time in ecological approaches to youth sports research through a repeated-measures design to properly operationalize the bioecological approach. The results of the present study do not support the argument that early specialization may lead to low enjoyment and consequent compromise in commitment and sustained participation in youth sports programs.

This research aimed to evaluate the training camp process of the East Java women's volleyball team in the Indonesia Olympic Games (PON) XX during Covid-19 Pandemic. This research was an evaluation study of the CIPP model with a mixed-method design. Two coaches and 15 women volleyball athletes were selected as research samples by purposive sampling method. The data were collected by questionnaire, observation, document analysis, and semi-structured interview techniques. Triangulation data and thematic coding methods were implemented to analyze the data. The results showed that the government supported the training process very well in the context dimension. The input dimensions were human resources, the availability of training programs, training facilities, and infrastructure was also in the excellent category. There was an excellent result on process dimensions. In the product dimension, most athletes have met the target of the training program. In conclusion, most of the dimensions are in a good category. In addition, the implementation of volleyball training in the covid-19 pandemic developed a good response and connection among athletes and coaches. Meanwhile, the negative values which occurred due to the limitation during the implementation of volleyball training in the covid-19 pandemic were boredom, unmotivated, and other psychological problems. Furthermore, limited training variations could be implemented, and game simulations were eliminated during the covid-19 pandemic.
