简要总结
This study aims to identify sporting talents by profiling a group of young boxers residing in the State of Mexico using unsupervised machine learning methods. This study is supported by Asociación de Boxeo del Estado de México AC (ABEM) and powered by DBSS.
详细描述
This cross-sectional study aims to identify sporting talents by profiling a group of young boxers residing in the State of Mexico. The primary outcomes encompass anthropometric, physical, and psychological variables associated with sports performance. In detail, a morphological and body composition analysis will be conducted using anthropometric data. Boxing performance will be assessed by measuring the average acceleration of straight punches over 6 seconds, impact force in the straight boxing punch using a load cell, reactive force index in a counter-movement jump on a force platform, maximum isometric strength in the mid-thigh isometric pull on a force platform, load-velocity profile in the squat exercise using a linear encoder, and cardiorespiratory fitness measured with digital spirometry. Psychometric variables will include well-being level calculated with PERMA+4, attention capacity, perceptual acuity, concentration using the Toulouse test, and coping mechanisms assessed through the coping modes scale.

结局指标
主要结局
Number of punches thrown within a specific timeframe
时间窗: <1 minutes
Corner brand accelerometers will be used to measure the quantity of straight punches performed within a 6-second timeframe.
Reactive force index
时间窗: <2 minutes
A force platform will be used to measure the lower-limbs reactive force index during a countermovement jump (CMJ)
Punch impact force
时间窗: <1 minutes
A load cell placed within a damping device will be used to measure the force applied after a straight boxing punch.
The acceleration of the fists in straight boxing punches
时间窗: <1 minutes
Corner brand accelerometers will be used to measure the acceleration of the fists during the execution of repeated straight punches over a period of 6 seconds
Cardiorespiratory fitness
时间窗: <3 minutes
A digital spirometry will be performed to measure the lung capacity of the participants. The Forced Expiratory Volume in the first second (FEV1) and Forced Vital Capacity (FVC) will be registered. Subsequently, the ratio FEV1/FVC will be calculated to obtain the percentage of forced vital capacity expelled in the first second.
Anthropometry-Based Analysis of Adiposity
时间窗: 10-15 minutes
Anthropometric measurements will be carried out to estimate body composition, following the protocol established by the International Society for the Advancement of Kinanthropometry (ISAK). The absolute values of the sum of skinfolds (∑S) and related variables, such as skinfold-corrected girths, will be used for measuring adiposity.
Isometric Mid-Thigh Pull
时间窗: <1 minutes
The participants' force production capacity will be assessed. The test will be conducted on a force platform.
Load-velocity profile
时间窗: <5 minutes
To estimate the load-velocity profile, the two-point method can be used, where two loads corresponding approximately to 40-50% and 70-80% of the one-repetition maximum (RM) for the squat exercise are employed. The velocity of the load is measured in each attempt. This approach provides a reliable alternative for evaluating muscle mechanical capabilities through the relationship of the load-velocity profile, which aids in predicting Maximum Dynamic Strength. Moreover, it can be a quick and secure method for predicting this parameter in various exercises.
