基于运动负荷熵理论的大学生运动觉差运动负荷分级与觉差感知实践研究

Exercise Load Classification and Perceptual Difference Awareness Training Based on Exercise Load Entropy Theory in University Students

摘要

摘要:
目的基于运动负荷熵测度理论，探讨大学生在不同运动负荷级别下运动负荷分级、觉差感知及韦伯分数的变化规律，为个性化运动负荷评估提供依据。
方法于2025年1月–2025年4月纳入138名大学生，采用功率自行车完成6个递增负荷级别的运动测试。根据受试者自觉运动负荷分级与觉差感知，计算各负荷级别下的觉差值和韦伯分数。采用单因素分析、相关分析及多重线性回归分析对数据进行统计处理。
结果随着运动负荷级别的增加，觉差感知总体呈下降趋势，但差异无统计学意义（P=0.156）。韦伯分数随负荷级别增加呈递减趋势，由负荷级2的0.49下降至负荷级6的0.11（P=0.034）。多重线性回归分析表明，运动负荷级别每增加1级，韦伯分数平均降低0.07〔95%置信区间（confidence interval, CI）：－0.12～－0.02，P=0.009〕；男性韦伯分数较女性低0.09（95%CI：－0.12～－0.06，P<0.001）。
结论在大学生群体中，运动负荷感知随负荷级别增加呈现非线性变化特征，韦伯分数随负荷增强而降低。

Abstract:
Objective Based on exercise load entropy measurement theory, this study aimed to investigate patterns of change in exercise load classification, perceptual difference awareness, and Weber fraction among university students across different exercise load levels, thereby providing theoretical support for personalized exercise load assessment.
Methods From January to April 2025, 138 college students completed six incrementally increasing load tests on a cycle ergometer. Based on self-perceived load staging and perceptual discrimination, discrimination thresholds and Weber fractions were calculated for each load level. Data were analyzed using univariate analysis, correlation analysis, and multiple linear regression analysis.
Results With increasing exercise load levels, differential perception showed an overall downward trend, but the difference was not statistically significant (P = 0.156). The Weber fraction decreased progressively with increasing load level, from 0.49 at load level 2 to 0.11 at load level 6 (P = 0.034). Multiple linear regression analysis indicated that for each one-level increase in exercise load, the Weber fraction decreased by an average of 0.07 (95% CI: －0.12 to －0.02, P = 0.009). In addition, males had a lower Weber fraction than females (95% CI: －0.12 to －0.06, P < 0.001).
Conclusion Among college students, the perception of exercise load changes nonlinearly as the load level increases, and the Weber fraction decreases as the load intensifies.
