Core Viewpoint - The article highlights the increasing popularity of jump rope as a physical activity among students and the need for standardized quality regulations in the jump rope industry, with a new national standard set to be implemented on July 1, 2025 [1]. Group 1: Standardization and Regulations - The new standard, titled "Jump Rope" (GB/T 45544―2025), will enforce strict requirements on safety, durability, and functionality of jump rope products [1]. - The China Consumers Association, in collaboration with the China Sporting Goods Federation, advises consumers to check product labels for compliance with the new standards and to avoid "three-no" products [1]. Group 2: Material Safety - Jump ropes must meet limits for harmful substances such as phthalates (≤0.1%) and heavy metals (e.g., lead ≤600mg/kg) [2]. - Consumers are encouraged to assess material safety by observing color, avoiding overly bright or dark products that may contain excessive dyes or plasticizers [2]. - The presence of strong plastic or glue odors may indicate the risk of harmful substance exceedance [3]. - The texture of the material should be smooth without burrs, and plastic components should not be overly soft or sticky, which could suggest excessive plasticizers [4]. Group 3: Usage Scenarios - For daily practice, basic jump ropes like bamboo or rubber ropes are recommended, ensuring they are lightweight and have non-slip handles [5]. - For examination purposes, jump ropes that meet school standards should be selected, with adjustable lengths and those that have passed fatigue tests to prevent breakage during use [5]. - For fitness training, electronic counting jump ropes are suggested, which should have durable materials and shock-absorbing handles to reduce joint strain [5]. - Competitive jump ropes should feature bearing structures for smooth high-speed rotation and lightweight materials to enhance speed and stability [5]. Group 4: Functional Testing - Consumers should ensure that the rope length can be adjusted securely to prevent retraction during use [6]. - The handles should have anti-slip features to maintain grip even when sweaty [6]. - A pull test should be conducted to ensure the jump rope can withstand a force of 50N (approximately 5 kg) without breaking or deforming [7].
