Even if you\u2019re short on time, taking just five minutes a couple times a day to move your body<\/a> can offer significant health benefits. New research shows these \u201cexercise snacks\u201d can improve heart and muscular fitness, particularly for people who are sedentary.<\/p>\n

\u201cWhat\u2019s important here is how little exercise is needed to make a difference. It shows that even small, consistent efforts can trigger real physiological adaptations when done regularly,\u201d says study author Miguel \u00c1ngel Rodr\u00edguez<\/a>, a doctoral candidate and researcher at the University of Oviedo in Spain.<\/p>\n

\u201cIt helps reinforce the message that every move counts,\u201d he adds.<\/p>\n

Quick, Intense Bursts of Exercise Had a Real Impact<\/p>\n

The study, published in the\u00a0British Journal of Sports Medicine, analyzed the effects of \u201cexercise snacks\u201d \u2014 short bouts of exercise<\/a> performed throughout the day \u2014 on cardiorespiratory (that\u2019s heart and lung) health, muscular fitness, and other measurements including body fat percentage and blood pressure.<\/p>\n

Researchers looked at data from eleven randomized clinical trials that included more than 400 adults ages 18 to 80 in Australia, Canada, China, and the United Kingdom. Nearly 70 percent of participants were women, and all reported being physically inactive before the trials began.<\/p>\n

The participants completed at least two daily exercise snacks (defined as moderate-vigorous to near-maximal physical activity for five minutes or less), three times a week or more, over a period of 4 to 12 weeks.<\/p>\n

Key findings included:<\/p>\n

Exercise snacks like stair-climbing<\/a> and body weight exercises significantly improved heart and lung fitness in participants ages 65 and younger.Exercise snacks such as tai chi<\/a> or leg-focused strength exercises significantly improved muscular endurance in participants ages 65 and older.<\/a>A large majority of participants (83 percent) were likely to stick to the exercise snack routines, suggesting that regular bouts of activity could make a real difference outside a study setting.<\/p>\n

The benefits seen in this trial are a big deal because cardiorespiratory fitness reflects a person\u2019s overall health and disease risk, says Kathryn Weston, PhD<\/a>, a senior lecturer of physical activity for health at the University of Strathclyde in Scotland, who has researched the impact of exercise snacks on health outcomes.<\/p>\n

\u201cCardiorespiratory fitness can be described as a physical trait, reflective of the integrated function of numerous bodily systems to deliver and use oxygen to support muscle activity during exercise and physical activity,\u201d she says.\u201d<\/p>\n

The higher your cardiorespiratory fitness, she notes, the lower your risk of early death and chronic conditions like heart disease<\/a> and diabetes<\/a>.<\/p>\n

Exercise Snacks Didn\u2019t Seem to Affect Blood Pressure or Weight \u2014\u00a0But There May Be a CatchUnlike previous research on the topic, heart health indicators<\/a> like blood pressure, blood lipid levels, and body fat percentage were not significantly affected by exercise snacks in the study.<\/p>\n

[3]<\/p>\n

Blood lipids<\/a>, or fats freely circulating in the blood, include triglycerides and LDL \u201cbad\u201d and HDL \u201cgood\u201d cholesterol<\/a>. Too much lipid buildup can have harmful health effects, including raising the risk of heart disease.<\/p>\n

[4]<\/p>\n

<\/p>\n

There could be a few factors behind the lack of improvement in heart health markers seen in this study, says Matthew Jones, PhD<\/a>, an exercise physiologist and senior lecturer at the School of Health Sciences at the University of New South Wales in Australia.<\/p>\n

Dr. Jones, who was not involved in the research, has studied the effects of short exercise sessions on cardiorespiratory health and other outcomes.<\/p>\n

\u201cChanges in blood pressure, blood lipids, and body composition [the ratio of muscle to fat] by exercise usually require larger doses of exercise to see significant improvements, and most of the exercise snack interventions included in this review used relatively modest doses of exercise,\u201d Jones says.<\/p>\n

\u201cCombining exercise snacks with dietary modification<\/a> might be an effective way to improve these parameters more, he says, explaining that the effect of combining these approaches might be more effective than exercise snacks alone.<\/p>\n

Weston says that the study design might have played a role, as well. \u201cThe varied \u2018dose\u2019 of the exercise snacks \u2014 snacks across the included studies were performed at different intensities, using different modes of exercise, and completed over different periods of time \u2014\u00a0may also partly explain the lack of meaningful changes here,\u201d she says.<\/p>\n

Why Our Bodies Need MovementEvidence suggests that sitting for long periods of time<\/a> can increase the risk of heart disease, even if you typically exercise regularly \u2014 which is why trying to move a little more throughout your day can be so beneficial.<\/p>\n

[5]<\/p>\n

While exercise snacks can benefit everyone, Bjorn T. Tam, PhD<\/a>, an assistant professor at the Academy of Wellness and Human Development at Hong Kong Baptist University in China, says that they may be particularly helpful for people who aren\u2019t very active.<\/p>\n

[6]<\/p>\n

<\/p>\n

\u201cThis is a classic principle in exercise physiology: The less fit you are, the more noticeable your initial improvements will be when you start exercising<\/a>. If you\u2019re already very active, a few extra exercise snacks probably won\u2019t change much. But for a sedentary office worker, these small bouts of exercise can be life-changing,\u201d says Tam.<\/p>\n

\u201cWhile these exercise snacks aren\u2019t a replacement for traditional workouts or a strategy for major weight loss, they are a practical first step to becoming healthier,\u201d he says.<\/p>\n

Exercise Snacks to Get You Moving<\/p>\n

Weston and Jones offered several \u201csnacktivity\u201d ideas for people without underlying health conditions or physical limitations:<\/p>\n

Stair-climbing for three to four flightsBody weight exercises,\u00a0like squats, static lunges<\/a>, step-ups, and push-upsResistance band exercises<\/a>, such as bicep curls or pull-apartsWalking-based exercises,\u00a0like high-knee marches or jogging in place<\/p>\n

To sprinkle them throughout your day, Tam suggests breaking up your sitting time every 45 minutes to an hour, aiming for 20 to 30 reps per minute for exercises like squats. \u201cDoing six to eight one-minute bursts of exercise each day can really add up,\u201d he says.<\/p>\n

It doesn\u2019t take long for most people to notice a difference, Rodr\u00edguez says. \u201cEven within a few weeks, people may notice improvements in stamina, energy levels, and functional capacity. For example, climbing stairs with less effort or recovering faster after exertion,\u201d he says. \u201cAs we like to say, every move counts, and consistency always wins.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Even if you\u2019re short on time, taking just five minutes a couple times a day to move your…\n","protected":false},"author":2,"featured_media":193293,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[46],"tags":[6647,102,56,54,55],"class_list":{"0":"post-193292","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-fitness","8":"tag-fitness","9":"tag-health","10":"tag-uk","11":"tag-united-kingdom","12":"tag-unitedkingdom"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/193292","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=193292"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/193292\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/193293"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=193292"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=193292"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=193292"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
