Seasonal Accumulated Workloads in Collegiate Women’s Soccer: A Comparison of Starters and Reserves

Research quantifying the unique workload demands of starters and reserves in training and match settings throughout a season in collegiate soccer is limited. Purpose: The purpose of the current study is to compare accumulated workloads between starters and reserves in collegiate soccer. Methods: Twenty-two NCAA Division III female soccer athletes (height: 1.67 ± 0.05 m; body mass: 65.42 ± 6.33 kg; fat-free mass: 48.99 ± 3.81 kg; body fat %: 25.22 ± 4.78%) were equipped with wearable global positioning systems with on-board inertial sensors, which assessed a proprietary training load metric and distance covered for each practice and 22 matches throughout an entire season. Nine players were classified as starters (S), defined as those playing >50% of playing time throughout the entire season. The remaining 17 were reserves (R). Goalkeepers were excluded. A one-way ANOVA was used to determine the extent of differences in accumulated training load throughout the season by player status. Results: Accumulated training load and total distance covered for starters were greater than reserves ((S: 9431 ± 1471 vs. R: 6310 ± 2263 AU; p < 0.001) and (S: 401.7 ± 31.9 vs. R: 272.9 ± 51.4 km; p < 0.001), respectively) throughout the season. Conclusions: Starters covered a much greater distance throughout the season, resulting in almost double the training load compared to reserves. It is unknown if the high workloads experienced by starters or the low workloads of the reserves is more problematic. Managing player workloads in soccer may require attention to address potential imbalances that emerge between starters and reserves throughout a season.

Developing an Intentionally Designed Physical Activity Model of Programming for Children’s Structured Recreation in Canada

Sport and education organizations have established models to ensure that coaches and teachers understand the physical, social, emotional and mental development of children. Such pathways of intentionally designed models fail to exist in the recreation sector where many physical activity (PA) programs are mainly developed based on convenience and instructor availability rather than on established credentials and current pedagogy practices. Addressing this gap, this paper explores the creation of an intentionally designed model of programming for children’s structured recreation, which is defined as sport or PA-based programs that are planned and led by an instructor. This proposed model is contextualized within the province of Alberta, but may be applicable across the nation. The authors further define “intentionally designed” as the development of purposeful programming with specific objectives that align with outside sources. One such source comes from the Canadian Parks and Recreation Association, who has created a Canadian Recreation Framework, an initiative to ultimately develop the well-being of all Canadians. The proposed, structured recreation model also incorporates several guiding principles including physical literacy and sport philosophy. Physical Literacy (PL) focuses on the lived body as the embodied dimension of our human experience, and how it can be enriched through various experiences that enable us to reach our full potential (Whitehead, 2007). It is about viewing the body holistically rather than separate from the entire being. By planning diverse PA in four environments, including land, water, air, and ice, the model also aligns with the sports sector and its philosophy of developing both fundamental movement skills and fundamental sport skills. Moreover, with allocated playing time, intentionally designed structured lesson plans, and one consistent leader in each activity, the model aims to increase the participants’ motor proficiency and levels of PA while building their confidence and competence across distinct exercises. The execution of the proposed recreation model involves a four-month program where participants rotate to a different PA environment each month and attend two classes per week, cumulating in 32 total classes. Management implications are discussed to determine how recreational professionals can achieve the intended outcomes of the model. Finally, further research is necessary to determine if this model can increase participants’ motor proficiency and positively influence physical activity behaviors in the recreation sector.

The influence of different game formats on technical actions and playing time parameters – A study with under-7 and under-9 soccer players in a competitive context

Soccer competitions in childhood should ensure a high involvement of all players regardless of their talent. The purpose of the present study was to compare soccer players’ technical actions and playing time parameters in 7v7 in comparison to 3v3 (on mini-goals without goalkeepers; under-7) and 5v5 (on 1.65 × 5 m. goals with goalkeepers; under-9) game formats in a competitive context. Using a quasi-experimental within-subject design, tournaments with under-7 ( n = 42) and under-9 ( n = 43) players were conducted. Technical actions and playing time parameters were rated. Based on the total number of technical actions in 7v7, median splits of the samples were conducted to compare differences between high-involved (dominant) and low-involved (non-dominant) players. No differences in the effective playing time comparing game formats within the age groups were found. In total, 7884 technical actions were rated. In both age groups, the total number of technical actions was higher in the smaller game formats. In under-7, the number of technical actions in all variables was higher in 3v3. In under-9, the number of technical actions was also higher in 5v5 except for unsuccessful passes as well as successful 1v1 situations. More unsuccessful 1v1 situations were found in 7v7. Concerning the total number of technical actions, both dominant and non-dominant players in both age groups performed more technical actions in small-sided games. Due to the higher involvement of the children, better conditions for the acquisition of soccer-specific skills in the smaller game formats compared to 7v7 game formats can be concluded.

Comparative Evaluation of the Nutritional Status and Habits of Students Studying in Private and Government Schools in a Semi-Urban Town in India –Kumbakonam Urban Rural Epidemiological Study - KURES -1

Malnutrition is a universal and an ever-rising problem due to changes in the lifestyle and eating habits among the children. The malnourished children are prone to illness. Hence, we planned to conduct a study in school children, both in Government set up and a private set up, to review their nutritional status and the influencing factors. Two thousand students in the age group of 8-17 years were interviewed for their food habits, asking them to fill up a proforma along with anthropometric measurements. Among the children interviewed 72% were malnourished, but only 0.06% were obese. The nourishment was significantly better in private school children but still 58% were underweight. There was a strong liking for fast food among children from both the groups. The playing time was less than an hour in a majority of students. Conclusion: There is an alarming census of underweight children in a semi-urban Indian town, but obesity is not that alarming, with an incidence rate < 1%. There is an urgent need to promote games among children of all socioeconomic status. A blanket ban on fast food items in the school campus is the need of the hour. Undernourished children form majority of students going to school in India. This includes children attending private paid schools. The incidence of obesity is still so low so that any community level action on the same is presently not needed in India.

Maturational effect on physical capacities and anabolic hormones in under-16 elite footballers: a cross-sectional study

Purpose The purposes of this study were to describe the fitness and hormonal levels according to playing time (PT) (i.e., PT during season less (PT1) or more (PT2) than 50% of the total time) and maturation level (ML) (i.e., normal (ML1) and early maturity levels (ML2)), and to analyze the differences between groups for the measures of aerobic capacity, anaerobic power, power performance, and hormonal concentrations. Methods Twenty-four youth footballers of a U16 team participated in this study. Anthropometric measures, maturity status, growth hormone, insulin-like growth factor (IGF-1), maximal oxygen uptake, fatigue index, and countermovement jump were collected. Results Significant differences were found between both PT and ML groups for maturational status, aerobic capacity, power performance, and IGF1 concentrations. The interaction of PT and ML revealed significant differences for maturity offset and power performance. When using the skeletal age as a covariant, the previously significant differences found were reduced only to the fatigue index measure. Conclusions The response variables analyzed in the present study seem to be influenced by PT and ML. This must be considered when planning training, and coaches must be sensible to these effects as they may assume a preponderant role in PT.

Running Performance of Male Versus Female Players in Australian Football Matches: A Systematic Review

Background Australian Football is a fast paced, intermittent sport, played by both male and female populations. The aim of this systematic review was to compare male and female Australian Football players, competing at elite and sub-elite levels, for running performance during Australian Football matches based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Methods Medline, SPORTDiscus, and Web of Science searches, using search terms inclusive of Australian Football, movement demands and microsensor technology, returned 2535 potential manuscripts, of which 33 were included in the final analyses. Results Results indicated that male athletes performed approximately twice the total running distances of their female counterparts, which was likely due to the differences in quarter length (male elite = 20 min, female elite = 15 min (plus time-on). When expressed relative to playing time, the differences between males and females somewhat diminished. However, high-speed running distances covered at velocities > 14.4 km·h−1 (> 4 m·s−1) were substantially greater (≥ 50%) for male than female players. Male and female players recorded similar running intensities during peak periods of play of shorter duration (e.g., around 1 min), but when the analysis window was lengthened, females showed a greater decrement in running performance. Conclusion These results suggest that male players should be exposed to greater training volumes, whereas training intensities should be reasonably comparable across male and female athletes.

Physiological Profile, Metabolic Response, and Temporal Structure in Elite Individual Table Tennis: Differences According to Gender

No research that has analyzed the structural characteristics, physiological profile, and energy demands in the game of table tennis as played by women is available. The present study aimed to evaluate the physiological, metabolic, and temporal variables of table tennis players and to observe gender differences. Forty-eight elite table tennis players participated in this study: 24 men (25.3 ± 4.07 years) and 24 women (22.3 ± 3.8 years). During simulated competition, temporal structure, heart rate (HR), and lactate (LA) were evaluated. The maximum ergospirometric evaluations were performed in a laboratory. The total table tennis (TT) time and the total resting time (TRT) were longer for men (p < 0.05), but game density was higher for women (p < 0.05). During rallies, the real playing time (RPT) was longer for women, while the TRT was longer for men (p < 0.05). The maximum HR, minimum HR, and maximum LA concentrations were higher for men (p < 0.05). The obtained data reveal gender differences in the physiological, metabolic, structural, and temporal variables in table tennis players. The analysis of the studied variables could allow training sessions to be planned and organized according to table tennis players’ gender.

The effects of video gaming on academic effectiveness of higher education students during emergency remote teaching

The pandemic caused a new digital scheme of work to be implemented in higher educational institutes to avoid physical contact, which is referred to as emergency remote teaching in the literature (Hodges, Moore, Lockee, Trust, & Bond, 2020). The inevitable consequence of emergency remote teaching (later on ERT) was that the students’ inter-and extra organisational relationships decreased significantly (Pusztai & Győri, 2021). Based on the results of previous studies, we know that the lack of student relationships is strongly related to ineffectiveness (Astin, 1993; Pusztai, 2015; Tinto, 1975), which was also identified during the period of ERT (Pusztai & Győri, 2021). In the current study, firstly, we hypothesised that the students’ social interactions, which were accomplished by video gaming, could compensate for isolation (Pisan, 2007) and improve their effectiveness. Secondly, we hypothesised that video gaming might prove ineffective due to stressful and uncertain periods as well as avoidance of activity. In our study, we applied database analysis (Learning Alone database, N = 677) and half-structured interviews (N = 19). In the quantitative sample, we identified that increased gaming time (compared to the time spent before the pandemic) was related to persistence reduction, whereas similar results were obtained with the reduced playing time. In addition, the interview participants reinforced that they used video gaming as a tool to maintain their relationships during ERT, and they tended to do so in their relationships with other students as well. Thus it can be said that video gaming is an extracurricular activity that could affect academic effectiveness positively and negatively at the same time.

Return to Play (RTP) and Performance in the Women’s National Basketball Association (WNBA) Following Anterior Cruciate Ligament (ACL) Reconstruction (194)

Objectives: The incidence of ACL injuries in WNBA athletes has been on the rise, despite the high rates of ACL injury there is a paucity of recent research examining the effect of ACL reconstruction on RTP and performance in these athletes. This cohort study seeks to quantify the effect of ACL reconstruction on RTP and performance on WNBA athletes. Methods: All ACL tears sustained in the WNBA from 1997-2018 were identified. BMI, age and position at the time of injury were collected for each player. RTP rates were calculated and performance data was collected for each player before and after injury to determine changes in playing time and statistical performance. Players who successfully RTP after ACL reconstruction were compared to a group of healthy controls who were matched by age, years of experience, position, height, and BMI. Statistics at one year and three years’ post-injury were compared to assess acute and longitudinal changes in performance relative to pre-injury baseline. Results: A total of fifty-nine WNBA players sustained an isolated ACL tear during the study period. Forty-one (69.5%) were able to RTP. There was no difference in demographic characteristics between forty-one players and matched controls. Following RTP athletes played an average of 7.5±12.8 fewer games, 5.1±9.2 fewer minutes per game, and scored 3.7±5.0 less points per game in their first year compared to the year prior to injury. (Table1) When compared to matched controls, WNBA players returning from ACL reconstruction demonstrated a significant decline in games played, games started, minutes per game, rebounds, assists, and blocks per game in their first season after RTP. These differences resolved by year three post-surgery (Table 2). Conclusions: There is a high RTP rate following ACL reconstruction in WNBA athletes. Players may experience a decrease in playing time and performance initially when returning to play, however these variables were found to return to baseline over time.
