Purpose: To analyze the contribution of physical measures and external load in the match-based internal load of elite soccer players. Methods: Twenty-three elite soccer players (n = 23, age 26.69 ± 3.93 years, body mass 78.04 ± 5.03 kg, height 178.04 ± 5.19 cm, body fat 10.98 ± 1.25%) from a first division soccer team of the Brazilian Championship…

Purpose: The purpose of this article was to systematically review studies that explored associations between specific curricular models, as an essential component of physical education, and to assess how the student outcomes identified in the models aligned with the national standards. Methods: Using the PRISMA guidelines to identify, screen,…

Purpose: The aim of this study was to analyze the relationship between physical preparation, training sessions (TS) and friendly matches' (FM) demands, and playing status during European Championship (EC). Method: Twelve under-16 (U-16) basketball players performed physical (jumping, agility, aerobic fitness, and lower limb asymmetry index [ASI])…

Purpose: The purpose of this study was to identify the skills, knowledge, and experiences differentiating expert and competent strength and conditioning (S&C) coaches. Method: The participants were 87 elite-level head S&C coaches with an average of over 18 years of coaching experience. These coaches were employed by teams from the MLB,…

Purpose: To identify the role of content specificity in moderating situational interest and its relationship with physical activity (PA), we examined the between- and within-content relations of situational interest and PA in an urban elementary physical education context using fitness and basketball as comparative contents. Method: Fourth and…

Purpose: The purpose of this study was to determine the reliability, validity, and usefulness of 30--15 Intermittent Fitness Test (30-15[subscript IFT]) in female basketball players. Methods: Nineteen female basketball players (17.82 ± 1.94 yr, 175.4 ± 7.3 cm, 67.9 ± 7.7 kg) competing in the National Croatian League performed one trial of a…

Match activity demands of basketball players have been well reported but little exists in terms of quantifying the demands encountered by referees during match-play. Potential differences between referees and players may identify different fitness capacities and subsequent need for different training regimes. Purpose: The aims of this brief report…

Purpose: To evaluate vascular function and its relationship to cardiorespiratory fitness in professional handball athletes. Method: We examined 30 male professional handball athletes (age 27 [plus or minus] 4 y) and 10 male sedentary controls (age 26[plus or minus] 5 y) at rest. The workup included exercise testing via ergometry. To assess…

Purpose: The purpose of this study was to quantify and compare training and competition demands in basketball. Methods: Fifteen semiprofessional male basketball players wore microsensors during physical conditioning training (PCT), games-based training (GBT), and competition to measure absolute and relative (·min[superscript -1]) PlayerLoad™ (PL)…

Research from several countries has documented a decline in physical activity (PA) levels and in participation in organized sport with increasing age, indicating that organized sport may be of importance to adolescents' cardiorespiratory fitness (CRF). Purpose: The purpose of this study was to examine how regular participation in organized and…

Relative age effects (RAEs; when relatively older children possess participation and performance advantages over relatively younger children) are frequent in male team sports. One possible explanation is that coaches select players based on physical attributes, which are more likely witnessed in relatively older athletes. Purpose: To determine if…

The purpose of this study was to examine (a) the effects of three curricular activities on students' situational motivation (intrinsic motivation [IM], identified regulation [IR], external regulation, and amotivation [AM]) and physical activity (PA) levels, and (b) the predictive strength of situational motivation to PA levels. Four hundred twelve…

This study examined how activity type influenced heart rates and time spent in target heart rate zones of high school students participating in physical education classes. Significantly higher average heart rates existed for fitness (142 plus or minus 24 beats per minute [bpm]) compared to team (118 plus or minus 24 bpm) or individual (114 plus or…

This study examined the factor structure of the Sport Friendship Quality Scale (SFQS; Weiss & Smith, 1999) and compared two models in which (a) self-worth mediated the relationship between physical self/friendship quality and sport commitment and (b) friendship quality and physical self-perceptions directly predicted self-worth and sport…
