Application of ARIMA model in classification and prediction of athlete training data

Journal of Computational Methods in Sciences and Engineering, Год журнала: 2025, Номер unknown

Опубликована: Март 11, 2025

Traditional athlete training data classification and prediction models have low accuracy, poor processing of high-dimensional data, weak dynamic adaptability. Before applying the ARIMA model for prediction, first step is to use an automated acquisition system connect sports devices, collect clean in real time, securely store backup it on a central server. The second preprocess collected divide into test sets ensure accuracy generalization ability model. third conduct time-series analysis identify time-dependent seasonal components data. fourth involves fitting through differential analysis, stationarity testing, parameter optimization, residual rolling forecasting, ensemble learning, predicting classifying so as improve robustness experimental results show that using highest, all exceeding 92%, average 2%–16.7% higher than other models. Moreover, errors are below 1.0%. In summary, application highly reliable.

Since December 2019, the COVID-19 pandemic has spread globally, prompting governments in many countries to implement lockdowns control transmission of virus. Outbreaks emerging infectious diseases, such as COVID-19, and associated government may have significant negative impacts on mental health. A comprehensive review available evidence this topic can provide useful information for policymakers. This aimed assess effects health general population during disease outbreaks. On April 11, 2022, we conducted a systematic search CENTRAL, MEDLINE, PsycINFO Ovid, two clinical trial registries, supplemented by reference checking citation searching. We included non-randomized studies interventions (NRSIs) involving adults adolescents, regardless comorbidities, that examined government-imposed compared no lockdown outbreaks including SARS, MERS, H1N1, equine influenza, avian Ebola virus disease.

International Journal of Sports Physiology and Performance, Год журнала: 2022, Номер 18(1), С. 37 - 46

Опубликована: Дек. 5, 2022

The COVID-19 lockdown challenged the training options of athletes worldwide, including players from most popular sport globally, football/soccer. Purpose : authors explored practices football worldwide during lockdown. Methods Football (N = 2482, 30% professional, 22% semipro, and 48% amateur) completed an online survey (May–July 2020) on their before versus (March–June 2020). Questions were related to frequency session duration, as well knowledge attitudes. Results Before lockdown, more professional (87%) than semipro (67%) amateur (65%) trained ≥5 sessions/wk, but this proportion decreased 55%, 35%, 42%, respectively. Players (80%–87%) ≥60 minutes 45% in professionals, 43% amateurs, 36% semipros At home, two-thirds had space (73%) equipment (66%) for cardiorespiratory training, while availability technical strength was <50% Interactions between coach/trainer player frequent (ie, daily) among (27%) (11%) (17%) players. Training load monitoring, albeit limited, mostly performed by fitness coaches, so with professionals (35%) amateurs (13%) (17%). players’ attitudes/beliefs toward relatively modest (50%–59%). Conclusion negatively affected especially semipros, example, frequency, intensity, technical, recovery, other coaching-related aspects. During lockdown-like situations, should be monitored closely provided appropriate support facilitate training.

Background In March 2020, the COVID-19 outbreak led to declaration of a pandemic. The accompanying restrictions on public life caused change in training routines athletes worldwide. present study aimed investigate effects 13-week supervised home program physical performance, sleep quality, and health-related quality professional youth soccer players during first lockdown Germany. Methods Eight (age range 16–19; height: 1.81 ± 0.07 m; body weight: 72.05 6.96 kg) from Bundesliga team Germany participated this study. During lockdown, they trained 5–6 days per week with home-based plans were monitored via tracking apps video training. To determine training, measurements taken before (March 2020) after (June period. Bioelectrical impedance analysis was used composition, an isokinetic strength test treadmill step test, including lactate measurements, measure performance. Two questionnaires responded order assess [Short-Form 36 Health Survey (SF-36)] (Pittsburgh Sleep Quality Index). Results When comparing period, we observed significant increases following variables: weight (72.05 kg vs. 73.50 6.68 kg, p = 0.034), fat mass (11.99 3.13 % 13.98 3.92 %, 0.030), index (22.04 0.85 kg/m 2 22.49 0.92 , 0.049), mental health component summary score (MCS) questionnaire SF-36 (53.95 3.47 58.33 4.50, 0.044).

Of around 2 billion Muslims worldwide, approximately 1.5 observe Ramadan fasting (RF) month. Those that RF have diverse cultural, ethnic, social, and economic backgrounds are distributed over a wide geographical area. Sleep is known to be significantly altered during the month of Ramadan, which has profound impact on human health. Moreover, sleep closely connected dietary lifestyle behaviors.This cross-sectional study collected data using structured, self-administered electronic questionnaire was translated into 13 languages disseminated Muslim populations across 27 countries. The assessed factors as independent variables, three parameters (quality, duration, disturbance) dependent variables. We performed structural equation modeling (SEM) examine how affected these parameters.In total, 24,541 adults were enrolled in this study. SEM analysis revealed RF, optimum duration (7-9 h) associated with sufficient physical activity (PA) consuming plant-based proteins. In addition, smoking greater disturbance lower quality. Participants consumed vegetables, fruits, dates, proteins reported better Infrequent consumption delivered food infrequent screen time also Conflicting results found regarding dining at home versus out parameters.Increasing intake important could help improve healthy for those observing RF. regular PA avoiding may contribute improving

Changes trivial small compared moderate camp, lockdown. Para-athletes, males, older athletes, less experienced married specific ethnicities appeared be more detrimentally (increased stress) by These negative experiences, however, largely reversed camps. During lockdown, reported increased evening snack consumption (+8%), later meal-times (+6%), decreased fluid intake (−6%), no breakfast (+7%). camps (12–18% improvements). Sport classification accounted for 16% (p = 0.001) Overall, socio-demographic factors, improvements routines, well-being, habits explained 28% In conclusion, better well-being have implications reduced stress. beneficial, but this observation case-by-case consideration, short split are recommended.
