In a widely-cited study published in February 2013 in the American Journal of Health Promotion, researchers at Oregon State University looked at more than 6,000 American adults and found that even small amounts of physical activity — like pacing while talking on the phone or doing some jumping jacks during commercials while watching TV, as long as these short bursts of exercise add up to 30 minutes a day — can be just as beneficial as longer workout sessions at the gym.
Previous studies from her lab have also shown that the exercise is linked to changes in the secretion of stress hormones like epinephrine (a.k.a. adrenaline) and norepinephrine. “Our work has shown that each moderate, relatively short exercise bout exerts regulatory/suppression effects over inflammatory activities of immune cells," says Hong, "and in order to maximize this ‘benefit,’ repeated and regular exercise is recommended. In fact, we have also found that higher physical fitness is associated with better regulation of inflammatory activities of immune cells through stress hormones even among obese individuals.”
Those buff lab rats might be smarter than we think. Various studies on mice and men have shown that cardiovascular exercise can create new brain cells (aka neurogenesis) and improve overall brain performance Aerobic exercise is the critical variable in an enriched environment that increases hippocampal neurogenesis and water maze learning in male C57BL/6J mice. Mustroph ML, Chen S, Desai SC, Cay EB, DeYoung EK, Rhodes JS. Neuroscience Program, The Beckman Institute for Advanced Science and Technology, University of Illinois at Urbana-Champaign, Urbana, IL, USA. Neuroscience. 2012 September 6;219:62-71. Aerobic exercise improves hippocampal function and increases BDNF in the serum of young adult males. Griffin EW, Mullally S, Foley C, Warmington SA, O’Mara SM, Kelly AM. Department of Physiology, School of Medicine, University of Dublin, Trinity College, Dublin, Ireland. Physiology & Behavior. 2011 October 24;104(5):934-41.. Ready to apply for a Nobel Prize? Studies suggest that a tough workout increases levels of a brain-derived protein (known as BDNF) in the body, believed to help with decision making, higher thinking, and learning. Smarty (spandex) pants, indeed.
There are accessories that can make exercise easier, and sometimes buying a new toy can add some much-needed fun to your routine. With apps like RunKeeper and Nike+, your smartphone is capable of tracking your vitals and progress. Wrist weights can add a new dimension to your workout, and, if you exercise at night, a headlamp can help you see what’s in front of you so you don’t trip.
Millions of women struggle to lose fat from their arms these days. Are you in a war with your flabby arms too? Fat arms are caused by sedentary lifestyle, unhealthy food habits, the body’s metabolic rate, medical issues, or even your genes. To address this problem you have to work extra hard on your triceps and biceps and lose overall weight from your body to get the desired result.
