Study participants were asked to wear wrist-worn accelerometers for seven days to measure their daily activity, and also underwent <a href=\"https:\/\/www.thoracic.org\/patients\/patient-resources\/resources\/cpet.pdf\" target=\"_blank\" rel=\"noopener noreferrer\" class=\"content-link css-90fpmc\">cardiopulmonary exercise testing<\/a> to assess their heart and lung health.<\/p>\n<p>\u201cCardiorespiratory fitness is a measure of how well your heart, lungs, and muscles work together in response to exercise,\u201d <a href=\"https:\/\/physiology.med.ufl.edu\/profile\/esser-karyn\/\" target=\"_blank\" rel=\"noopener noreferrer\" class=\"content-link css-90fpmc\">Karyn Esser<\/a>, PhD, professor and chair of the Department of Physiology and Aging in the College of Medicine at the University of Florida, senior author of this study, told Medical News Today.<\/p>\n<p>\u201cHigher values are strongly associated with longer lifespan and lower mortality risks,\u201d Esser explained.<\/p>\n<p>The study also evaluated the <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/37027387\/\" target=\"_blank\" rel=\"noopener noreferrer\" class=\"content-link css-90fpmc\">walking efficiency<\/a> of participants, which is considered another indicator of healthy aging.<\/p>\n<p>\u201cWalking efficiency provides an assessment of how efficiently the body uses energy to walk forward,\u201d Esser noted. \u201cThe more efficient you are, the farther you can walk. It\u2019s another measure of fitness.\u201d<\/p>\n<p>At the study\u2019s conclusion, Esser and her team found that participants who had the most activity during the active part of their day relative to their daily resting time, and whose maximum daily activity happened earlier in the day, were correlated to better cardiorespiratory fitness and walking efficiency.<\/p>\n<p><strong>\u201cWe found that earlier peak activity was associated with better outcomes even when you [take] into account the amount of activity,\u201d the researcher detailed. \u201cThis suggests that getting moving earlier in the day could provide a health benefit. In addition, we found that the amplitude of the activity, or amount of activity during the day was healthy, this is maybe not such a surprise.\u201d<\/strong><\/p>\n<p>Additionally, scientists observed that better health outcomes were correlated to having a greater consistency in daily activity patterns, with the highest activity time happening at the same time every day. <\/p>\n<p>\u201cThis was an interesting finding as, again, we took into account the amount of activity so this is saying that being consistent with your activity pattern is an additional parameter of your activity that likely contributes to healthy outcomes,\u201d Esser said. <\/p>\n<p>To sum up, Esser said that this study finds that maintaining a daily programme of activity that includes attention to the timing and consistency of activity is important for maintaining health as we age.<\/p>\n<p>\u201cWhile we are living longer, in general, we are not living healthier,\u201d she explained. \u201cSo it is important to find ways to help people maintain or improve their health while aging, [to] improve quality of life and diminish the impact of age-related chronic diseases.\u201d<\/p>\n<p><strong>\u201cWe suggest that the earlier time of activity and repeatability of the activity provide benefits in addition to just the activity alone,\u201d Esser continued. \u201cLastly, we propose that the timing and reproducibility of the activity are working with our intrinsic circadian clock system to maintain health.\u201d <\/strong><\/p>\n<p>\u201cWe are continuing to expand our clinical study of circadian, or time of day activity behavior, with other outcomes including sleep, pain, cognition, and mental health,\u201d she added. \u201cIn addition, my lab has ongoing preclinical studies to determine more mechanistically how the timing of activity impacts health with aging.\u201d<\/p>\n<p>MNT had the opportunity to speak with <a href=\"https:\/\/www.memorialcare.org\/providers\/cheng-han-chen\" target=\"_blank\" rel=\"noopener noreferrer\" class=\"content-link css-90fpmc\">Cheng-Han Chen<\/a>, MD, a board certified interventional cardiologist and medical director of the Structural Heart Program at MemorialCare Saddleback Medical Center in Laguna Hills, CA, about this study. <\/p>\n<p>\u201cThis study found an association between the timing of daily physical activity and measures of cardiopulmonary fitness,\u201d Chen commented. \u201cThis suggests that we may eventually be able to better tailor our exercise recommendations in order to optimize the physiological benefits.\u201d<\/p>\n<blockquote class=\"is-layout-flow wp-block-quote-is-layout-flow css-34gtoi\">\n<p>\u201cGetting regular exercise is an essential part of staying healthy as you get older. As our population ages, strategies to improve physical fitness may help us reduce the burden of disease in our society. More research will be needed to determine whether intentionally changing and optimizing the rhythm of daily physical activity will lead to better health outcomes.\u201d <\/p>\n<p>\u2013 Cheng-Han Chen, MD<\/p>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"Share on PinterestExercise timing and consistency can influence heart and lung fitness as we age.
