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.
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.
2,193 studies on the registry are indexed under Psychological Well-Being; 728 are open to participants now.
This study's enrollment of 178 is below the median of 300 across 358 observational studies indexed under Psychological Well-Being.

Anthropometry-Based Analysis of Adiposity
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.
Time frame: 10-15 minutes
The acceleration of the fists in straight boxing punches
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
Time frame: <1 minutes
Number of punches thrown within a specific timeframe
Corner brand accelerometers will be used to measure the quantity of straight punches performed within a 6-second timeframe.
Time frame: <1 minutes
Punch impact force
A load cell placed within a damping device will be used to measure the force applied after a straight boxing punch.
Time frame: <1 minutes
Reactive force index
A force platform will be used to measure the lower-limbs reactive force index during a countermovement jump (CMJ)
Time frame: <2 minutes
Cardiorespiratory fitness
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.
Time frame: <3 minutes
Isometric Mid-Thigh Pull
The participants' force production capacity will be assessed. The test will be conducted on a force platform.
Time frame: <1 minutes
Load-velocity profile
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.
Time frame: <5 minutes
Well-being profile
The PERMA+4 questionnaire will be administered to assess the well-being of the participants. The 10 circles in each domain represent a scale for evaluating well-being, where 1 is Completely Disagree and 10 is Completely Agree. A combined score is computed to report results.
Time frame: 5 minutes
Ways of Coping Questionnaire
The coping modes scale consists of 66 items, which are statements regarding coping strategies, addressing both emotion and problem-solving. Response options range from 0 to 3, where 0 corresponds to 'Not at all' and 3 to 'To a great extent.' The scales will be administered to participants at the camp during a relaxation period away from physical tests.
Time frame: <1 hour
Attention and Perceptual Processes
The Toulouse Test will be administered to measure individuals' attention capacity, perceptual acuity, concentration, as well as their resistance to monotony.
Time frame: 10 minutes
