The American Medical Association Journal JAMA published Prospective Associations of Different Combinations of Aerobic and Muscle-Strengthening Activity With All-Cause, Cardiovascular, and Cancer Mortality on 2023-8-7.
IntroductionThere are strong evidence to show the beneficial effects of moderate to intense aerobic exercise on reducing all-cause mortality, cardiovascular disease and cancer mortality in adults. Increased muscle strengthening activities (MSA) every week can enhance these benefits. In this regard, the 2018 American Physical Activity Guidelines and the 2020 World Health Organization Physical Activity Guidelines recommend a minimum of 150 to 300 minutes of moderate aerobic exercise (MPA), at least 75 to 150 minutes of dramatic aerobic exercise (VPA) per week, or an equivalent combination of two strength abilities activities for adults 2 days or more per week and MSA.
However, the best combination of weekly MPA, VPA, and MSA to reduce all-cause mortality, cardiovascular disease mortality, and cancer mortality remains unknown. Therefore, this study uses a large number of representative samples from American adults to examine the detailed associations of different combinations of MPA, VPA, and MSA with all-cause mortality, cardiovascular disease mortality, and cancer-specific mortality.
Study SubjectsThis prospective team study compiled data from a continuous 22-wheel US National Health Interview Survey (NHIS; 1997-2018). NHIS is a nationally representative survey conducted on the non-hospital population in the United States. It is conducted once a year by the Centers for Disease Control and Prevention’s National Health Statistics Center. From the qualifying samples of 646201 participants, we excluded people who currently have chronic diseases such as cancer (n = 41486), heart disease (n = 30183), lung (n = 5008), or medium (n = 8114). Those who lack aerobic activity data or who cannot perform aerobic activity (n = 27127) or MSA (n = 1464) were also deleted. In addition, we deleted individuals with missing variable data, including chronic diseases (n = 829), functional limitations (n = 481), marital status (n = 1049), education level (n = 2554), drinking (n = 4870), smoke state (n = 468), and body weight index (BMI;n = 14094). To avoid reverse causal bias, we ruled out mortality results for 2 years before visit (n = 7769). Therefore, the data analyzed in the final study were from 500,705 adults larger than 18 years old (average age of 46.4; 58% were female; 77% were white).
Research MethodRecreational time Body activity information is obtained through the following questionnaire survey: (1) Light body activity frequency: “How often do you conduct at least 10 minutes of light or moderate leisure sports activities that only cause light sweating or mild to moderate increase in breathing or heart rate? ” (2) MPA duration: “How long do you perform these light or moderate leisure activities each time? ” (3) VPA frequency: “How often do you perform at least 10 minutes of intense sports activities, resulting in a large amount of sweating or a significant increase in breathing or heart rate? ” (4) VPA's continuous time: “How long does it take for you to conduct these sports activities each time? ” Muscle strengthening activities are determined by the following questions: “How often do you perform physical activities dedicated to strengthening muscles, such as weightlifting or aerobics? ”
The death records of participants were taken from the National Death Index record before December 31, 2019. The
statistical analysis was conducted from September 1, 2022 to September 30, 2022. We used proportional Cox back to simulate the relationship between exposure categories and mortality from the interview date to the death or review date (December 31, 2019), based on the first arrival.
ResultAll Cause Mortality:Reference (Not Movement): 1 (Reference Baseline)
Best Movement Pack (MPA of 0 to 75 minutes per week + 150 minutes VPA of 150 minutes + > 2 times MSA): 0.50
Cardiovascular Disease Mortality:Reference (Not Movement): 1 (Reference Baseline)
Best Movement Pack (MPA of 150 to 225 minutes per week + 0 to 75 minutes VPA of 16gt; 2 times MSA): 0.30
Cancer mortality:Reference (Nothing): 1 (Reference Baseline)
Optimal Sports Combination (> per week; 300 min MPA + 0 to 75 min VPA + > 2 MSA): 0.44
ConclusionThis study shows that the balanced level combination of MPA (moderate aerobic exercise), VPA (sporty aerobic exercise), and MSA (muscle strengthening activity) may be related to the maximum reduction in mortality risk. MPA and VPA above the recommended level may further reduce the risk of cancer and all-cause mortality, respectively.
Note 1: Please note that the subject of this study was a group with an average age of 46.4 years old. I personally think that older people, if you can (no need to play), you can do both aerobic and resistance movements, just be fine. However, I do think that if the body can and time allow, I should do it for 30 minutes or more every day.
