Sports injuries as reversible involution: A novel approach to rehabilitation and readaptation
This perspective article discusses the notions of reversible involution in sports injuries and offers an innovative operational framework for rehabilitation that we expect to help with the athlete's readaptation process. Injuries have traditionally been managed by relieving the symptoms and recovery, but physiological regulation based on the allostasis-interoception model suggests that these injuries are dynamic and reversible. This reconceptuali…
Analysis of Injuries and Wellness in Blind Athletes during an International Football Competition
Five-a-side football for blind people is the only adapted football modality present at the Paralympic games. Fa5 is a collaborative-opposition sport in which its participants play with no vision, which causes numerous impacts. At the London 2012 Paralympic Games, it was the sport with the highest incidence of sports injuries. The main objective of this work is to analyse the association between pain perception; spatio-temporal, mechanical, and me…
Kidney Function in Rice Workers Exposed to Heat and Dehydration in Costa Rica
The aim of this study was to evaluate heat exposure, dehydration, and kidney function in rice workers over the course of three months, in Guanacaste, Costa Rica. We collected biological and questionnaire data across a three-month-period in male field (n = 27) and other (n = 45) workers from a rice company where chronic kidney disease of unknown origin (CKDu) is endemic. We used stepwise forward regression to determine variables associated with es…
Profiling Physical Fitness of Physical Education Majors Using Unsupervised Machine Learning
The academic curriculum has shown to promote sedentary behavior in college students. This study aimed to profile the physical fitness of physical education majors using unsupervised machine learning and to identify the differences between sexes, academic years, socioeconomic strata, and the generated profiles. A total of 542 healthy and physically active students (445 males, 97 females; 19.8 [2.2] years; 66.0 [10.3] kg; 169.5 [7.8] cm) participat…
Measurement of resting muscle oxygenation and the relationship with countermovement jumps and body composition in soccer players (Medición de la oxigenación muscular en reposo y la relación con los sa…
The measurement of resting muscle oxygenation capacity is under investigation in team sports. The aim of the current study was to observe the changes after a preseason, in muscle oxygen saturation (SmO2) at rest and the relationship with body composition and jump power in soccer players. 17 soccer players (age 21.8 ± 2.2 years) were enrolled. Body composition, somatotype, countermovement jump (CMJ) and single-leg countermovement jump (SLCMJ) were…
On-Match Impact and Outcomes of Scoring First in Professional European Female Football
Scoring first is a determinant in the outcomes of professional European female football matches. Physical and tactical training and programming should focus on those variables, leading female teams to score first
Data Mining to Select Relevant Variables Influencing External and Internal Workload of Elite Blind 5-a-Side Soccer
(1) Background: Data mining has turned essential when exploring a large amount of information in performance analysis in sports. This study aimed to select the most relevant variables influencing the external and internal load in top-elite 5-a-side soccer (Sa5) using a data mining model considering some contextual indicators as match result, body mass index (BMI), scoring rate and age. (2) Methods: A total of 50 top-elite visually impaired soccer…
Outpatient Assessment of Mechanical Load, Heat Strain and Dehydration as Causes of Transitional Acute Kidney Injury in Endurance Trail Runners
Endurance trail running may lead to an increase in blood and urine indicators of transitional AKI. The difference in blood and urine markers was significantly related to the mechanical load during running, suggesting potential kidney overload and cumulative mechanical load
Influence of Contextual Variables in the Changes of Direction and Centripetal Force Generated during an Elite-Level Soccer Team Season
The study of the contextual variables that affect soccer performance is important to be able to reproduce the competition context during the training sessions. Therefore, the aim of the present study was to evaluate the effect of match outcome as related to goal difference (large win, >2 goals, LW; narrow win, 1-2 goals, NW; drawing, D; narrow loss, 1-2 goals, NL; or large loss, >2 goals, LL), match location (home, H; away, A; neutral, N), type o…
External Workload Indicators of Muscle and Kidney Mechanical Injury in Endurance Trail Running
Muscle and kidney injury in endurance athletes is worrying for health, and its relationship with physical external workload (eWL) needs to be explored. This study aimed to analyze which eWL indexes have more influence on muscle and kidney injury biomarkers. 20 well-trained trail runners (age = 38.95 ± 9.99 years) ran ~35.27 km (thermal-index = 23.2 ± 1.8 °C, cumulative-ascend = 1815 m) wearing inertial measurement units (IMU) in six different spo…
Accelerometry-Based External Load Indicators in Sport: Too Many Options, Same Practical Outcome
With the development of new microsensor technology to assess load in sports, some indicators of external load through accelerometry-based data have been created by sport technology companies. Thus, the study aim was to analyze the agreement between different accelerometry-based external load indicators (ABELIs) available in sport science. A U-16 male soccer team was assessed during three official matches, divided by periods, to obtain 3-D acceler…
Propuesta metodológica para efectuar un proceso de autoevaluación por conglomerado en carreras universitarias
El objetivo de este artículo fue sistematizar la experiencia metodológica vivida en el proceso de autoevaluación por conglomerado de carreras de grado universitarias que se encuentran en diferentes etapas de evaluación y que cuentan con dos unidades ejecutoras. Esta propuesta incluye las fases y etapas que exponen los detalles metodológicos, entre ellos: diseño de plan de acciones, reuniones permanentes colectivas para la sistematización y toma d…
