一 |     The automotive experts at Edmunds test SUVs of all shapes, sizes and prices. During these evaluations, certain models rise to the top with qualities such as roomy seating and cargo areas, a comfortable ride, and easy-to-use touchscreens and technology features. But with many prospective buyers looking to make every dollar count, it’s important to consider value as well.Working with a budget cap of $40,000, Edmunds picked five SUVs to highlight. Some have city-friendly proportions that take the stress out of parking in tight spots, while others have cavernous cargo holds and handy third-row seating. They are listed below in order of price, which includes the destination charge.2024 MAZDA CX-50The Mazda CX-50 small SUV earns a spot in this list thanks to its driving refinement and upscale cabin. From inside it’s not hard to believe that you’re behind the wheel of a luxury-badged model. The design is first-rate and the seats are supportive in either row. The CX-50 rides a bit more firmly over bumps than other SUVs, but in return it has stable handling and is enjoyable to zip around town in or take out on a scenic drive. All-wheel drive is standard on every trim, as are driver assist features such as lane keeping assistance, traffic-adaptive cruise control and blind-spot warning. A 186-horsepower four-cylinder serves as this Mazda’s capable and budget-minded base engine. There’s an optional turbo four-cylinder that’s more powerful, but it nudges the price at or above a $40,000 spending limit.Starting manufacturer’s suggested retail price: $31,6752023 KIA SORENTOThe Kia Sorento is a compelling choice for shoppers wanting a low-priced seven-passenger SUV. Its third-row seating area is smaller than those of bigger models — such as the Hyundai Palisade listed below — but it is still suitable for occasional use for kids. Most of the Sorento’s trim levels come well stocked with helpful convenience and technology features.There is a choice of a fuel-conscious, non-turbocharged 191-horsepower four-cylinder engine or a punchier 281-horsepower turbo-four available in higher trims. And it’s possible to opt for the more powerful engine and keep the Sorento’s price well below $40,000. A Sorento Hybrid is also available for shoppers seeking higher fuel economy. Starting MSRP: $31,4152024 HONDA CR-VThe Honda CR-V is about as well rounded as a small SUV can get. It delivers a smooth and comfortable ride, great outward visibility, and loads of cargo space. Fuel economy is another plus point. The CR-V’s base 190-horsepower turbocharged four-cylinder gets up to an EPA-estimated 30 mpg combined, or you can opt for the 204-hp hybrid powertrain that gets up to 40 mpg combined. Thanks to its recent redesign for the 2023 model year, the interior of the CR-V is attractive and functional. Picking the midgrade EX-L trim stays under our budget limit and still gets you some upscale features such as leather upholstery, a power liftgate and a bigger center touchscreen. Starting MSRP: $30,8252024 SUBARU OUTBACKThe Subaru Outback is ideal for SUV shoppers who want a vehicle that’s suitable for occasional off-road adventures. Thanks to its standard all-wheel drive and generous ground clearance, the midsize Outback has above-average capability on dirt roads or rocky trails. The Outback’s wagon-like shape also makes it easier to load recreational gear or cargo on the roof.Acceleration from the Outback’s standard 182-horsepower four-cylinder can be slow when you need a burst of speed on the highway, but in exchange the Outback gets a respectable EPA-estimated 28 mpg combined. A more powerful turbocharged four-cylinder is also available, though it exceeds our budget cap.Starting MSRP: $30,1902024 HYUNDAI PALISADEThe three-row Hyundai Palisade is the most expensive SUV among Edmunds’ choices here, and the majority of trims are priced beyond a $40,000 budget. But it’s important to know even the base Palisade is equipped with a long roster of tech features and driving aids. Highlights include a big 12.3-inch center touchscreen, first- and second-row USB ports, traffic-adaptive cruise control and blind-spot warning.All Palisades come with a 291-horsepower V6 engine that delivers acceptable acceleration and fuel economy. Despite its relatively large size, the Palisade is relaxing to drive and easy to maneuver. Also worth noting is its third-row seating has ample space even for adults, which is a rarity among many midsize SUVs. Starting MSRP: $37,735_______This story was provided to The Associated Press by the automotive website Edmunds.Nick Kurczewski is a contributor at Edmunds and is on Twitter and Instagram。    

中新网北京6月30日电 随着逐渐入夏,国内天气情况复杂,江南华南与强降雨作伴,华北黄淮高温天气增多。高温、高湿天气的出现,也对赛事组委会办赛、大众选手参赛提出了更高的要求。在这种情况下,如何办赛和参赛,中国田径协会为大家整理出来一份完整指南。

二 | 参赛篇 天气逐渐炎热,跑完步以后大汗淋漓的感觉或许很爽,但一定要知道高温高湿天气对跑步的人来说,是一个非常大的考验。

三 | 因为高温高湿造成的头晕等反应很有可能是中暑、热射病等的症状。

四 | 因此高温高湿天气如何参赛,下面这些你一定要知道! 高温天气 “三伏天”跑步勇气可嘉,但更要掌握这些高温天气跑步的知识点,毕竟“知己知彼才能百战不殆”! 识别高温天气 世界气象组织将持续3天以上、日最高气温高于32℃的天气定义为高温天气。

五 | 该环境下人体易感到不适,中暑等病症的发病率增多,此时跑步更要注意安全。

六 |

那么,在高气温天跑步,除了避开最热时段,选择轻薄、透气的速干衣裤外,我们还要注意以下细节: 注意心率而非配速 高温天气人体散热负荷大,易引发疲劳,进而导致运动表现下降,这是身体自我保护机制运转的结果。

七 | 建议将心率控制在最大心率(220-年龄)的60%-70%间,若心率过高应适当降低配速。及时补水是关键 补水是关键!跑步补水很重要,特别是补充电解质液体。尤其高温天气,跑前1小时饮水500-800毫升会有效降低脱水风险,跑步过程也要及时补充含电解质的液体,运动后补水量应大于汗液丢失量(可称量运动前后体重作为补水量的依据)。适当减少运动量 在热环境中运动量应保持在日常的70%-75%,例如平常跑10公里,高温天建议跑7-7.5公里就够了。更重要的是降低运动强度,通过运动强度的控制将心率控制在合理范围。此外,高温天气跑步一定量力而行,出现头晕头痛、心悸等症状,应停止运动,降温补液。

八 | 高湿天气 为什么那些气温不是很高但湿度很大的天气,跑起来却那么难受?这里面学问很大! 人的体感温度不仅受温度影响,还受到湿度影响。基于此,炎热指数将湿度温度的组合分为4个级别,表示户外活动风险。例如,长江中下游地区六月中旬到七月上旬前后的高湿天气通常在26-30度,虽然气温没有三伏天高,但湿度往往超过了80%,由于湿度高、气压低,很容易发生中暑。那么高湿天气跑步有哪些需要注意的? 其实,高温天气跑步注意事项同样适用于高湿天气,此外,你还需要注意这些细节。适当降低配速,加大呼气深度 气压低时,人体血液循环能力下降,血液携氧能力不足,容易出现呼吸不畅,跑步时呼吸更频繁。但过于频繁的呼吸反而会降低呼吸效率,因此应控制呼吸频率,加大呼气深度。同时,可有意识地降低速度,不要让身体负担过重。

九 | 控制运动强度 高湿天气运动,人体的氧使用效率与散热效率明显下降,容易感觉四肢沉重乏力,出现疲劳,因此要控制运动强度,避免过度刺激,防止中暑、运动性疲劳等状况。

十 | 增加训练频次,缩短训练时间 已经适应高湿天气的跑者,只需适当缩短训练时间,增加训练频次,避开暴雨等极端天气。但对于在该地区短暂逗留的人,即便有跑步习惯,高湿天气也建议停跑。跑步装备要带好 高湿天气湿度高散热差,脚底易磨出水泡,建议穿压缩袜,减少皮肤和鞋的摩擦。跑步时可以带上宽檐帽或一次性雨衣,以防突如其来的大雨。同时,要多备几双鞋。总之,高湿天气可以坚持跑步,但一定要注意这些细节。此外,下大雨时最好还是进行室内力量训练、游泳等。办赛篇 同样,对于赛事组委会来说,夏季办赛,遇到高温、高湿天气,一定要引起警惕,把参赛选手的生命安全放在首位。赛前,要建立赛事应急预案和赛事熔断机制,合理制定补给计划、增加医疗站等准备措施。赛中,要关注实时气象预报和参赛人员情况,遇到突发情况及时终止比赛。具体要注意以下几点: 提前做好应急预案,成立专项工作组,做好跨部门协同工作,并在赛前做好应预案的培训和演练; 联系当地气象局,并邀请其加入赛事组委会。提前收集比赛日过往三年的气象预报,在赛前和比赛中使用一个或多个可靠的气象信息来源。

十一 | 关注气象预报,天气预报应至少包含以下数据,并应确保至少每2小时更新: (1)不同海拔高度的预测温度范围; (2)风的起源点、覆盖区域及强度; (3)风寒指数; (4)湿度; (5)降水持续时间和降水量。

十二 | 选择合适的比赛路线,路线两侧尽量有高大的树木或建筑,避免阳光直射; 合理制定补给计划,按参赛人数配置充足数量的水、功能性饮料及盐分补给品;赛道沿途和终点增加喷淋点及冰块,必要时可以联系政府相关单位,在赛道沿途增加喷雾车; 缩短仪式流程,合理制定发枪时间,避开高温时段; 按赛事规模配置充足的补给,增加补给站设置和工作人员,增加特定的观察人员; 引入湿球黑球温度指数,在医疗站布置湿球黑球温度指数仪,做到实时监测、实时处置、实时上报;按赛事规模配置充足的救护车,增加医疗站设置和医护人员,增加特定的药品、喷壶、冰水池; 赛前通过官网、官微、短信等方式,告知选手、裁判以及志愿者等赛事相关人员比赛当天的天气情况,使其提前做好防暑降温准备;做好赛事相关工作人员的防暑防晒工作,配备遮阳帽和充足的饮用水; 建立熔断机制,出现极端天气情况应及时终止比赛;除天气因素外,还应关注事故灾难、公共卫生事件、社会安全事件以及发生其他可能导致不具备办赛条件的安全问题。
