Abstract

© JPES. Purpose: The purpose of this study was to profile the physiological characteristics of amateur boxers using a battery of tests designed to assess the physiological and physical demands required for performance. Fifteen junior amateur (age 14.9 ± 2.0 years; stature 164 ± 12 cm; body mass 50.9 ± 11.3 kg) and sixteen senior amateur boxers (n = 16; age 20.5 ± 4.0 years; stature 174 ± 9 cm; body mass 65.2 ± 10.7 kg) provided informed consent to participate in the study. Body composition, squat jump (SJ), countermovement jump (CMJ), 5-and 10 m sprint (5SP/10SP), press up (PU), right and left medicine-ball single-arm throws (MBR, MBL), repeated sprint test (RST) and Yo-Yo intermittent recovery test level 1 (YY) were performed. The likelihood (% chance) of between-group differences were assessed using a magnitude based approach, standardised-difference score (Cohen’s d) and 90% confidence intervals [CI]. Linear regression (r) was used to examine the association between variables. Results: Senior boxers outperformed (79 to 99% chance) junior counterparts in PU, YY, CMJ, SJ, 10SP, MBL and MBR tests (d ≥ 0.50 [-0.34 to 1.61]). There were very large (r 0.70) correlations between fat free mass, upper-and lower body lean mass and medicine ball throw distance. There were large correlations (r 0.50 to 0.69) between medicine ball throw distance and CMJ, SJ, PU, 5SP and 10SP. Conclusions: A simple and time-effective test battery was able to differentiate performance between junior and amateur boxers. These assessments could be useful when profiling junior and senior amateur boxers.

初级和高级业余拳击手的身体状况

©JPES。目的：本研究的目的是通过一系列测试来了解业余拳击手的生理特征，这些测试旨在评估表现所需的生理和身体需求。15名初级业余拳击手（年龄14.9±2.0岁；身高164±12厘米；体重50.9±11.3公斤）和16名高级业余拳击手（n=16；年龄20.5±4.0岁；身高174±9厘米；体重65.2±10.7公斤）提供了参与研究的知情同意书。分别进行了身体组成、深蹲跳跃（SJ）、反跳（CMJ）、5米和10米短跑（5SP/10SP）、俯卧撑（PU）、左右健身球单臂投掷（MBR、MBL）、重复冲刺试验（RST）和Yo-Yo间歇恢复试验一级（YY）。使用基于量值的方法、标准化差异评分（Cohen’s d）和90%置信区间[CI]评估组间差异的可能性（%几率）。线性回归（r）用于检验变量之间的相关性。结果：在PU、YY、CMJ、SJ、10SP、MBL和MBR测试中，高级拳击手的表现优于初级拳击手（79%至99%的概率）（d≥0.50〔-0.34至1.61〕）。药球投掷距离与CMJ、SJ、PU、5SP、10SP呈显著正相关（r 0.50～0.69）。结论：一个简单有效的测试电池能够区分初级和业余拳击手的表现。这些评估在分析初级和高级业余拳击手时可能很有用。

期刊介绍： The main objective of JPES is to unite specialists from different fields, including sport, physical activity, kinesiology, education, health and nutrition, to provide the opportunity for multidisciplinary debates and comprehensive understanding of how physical activity influences human life. Researchers from areas that are related to sport and health are invited to publish their cutting-edge research and its practical applicability. Our target group of expert specialists includes academic researchers, kinesitherapists, physical education and sports teachers, physicians in sports medicine, psychologists, nutritionists, coaches and any other researchers involved in the sports field. JPES aims to act as a stimulus and a dissemination instrument for the research activity of Romanian and foreign investigators. JPES primarily publishes articles in the following fields: the natural sciences of sport, social and behavioral sciences and humanities, sports management, sports medicine, sports pedagogy and sport itself. The journal also aims to facilitate and enhance communication across all sub-disciplines of the sport sciences. The journal awaits original papers, review articles, technical reports and short communications that contain new insight into any aspect of the sport sciences that have not been previously published and are not under consideration for publication elsewhere.
