summary: A new study suggests that regular aerobic exercise, even less than the recommended 150 minutes per week, may significantly reduce the risk of death from flu and pneumonia.
However, beyond a certain level of activity, the benefits seem to plateau or even become detrimental, especially in strength training. The study evaluated responses from more than 577,000 adults who participated in the US National Health Interview Survey (NHIS) from 1998 to 2018.
The study highlights that people who meet both aerobic and strength goals have almost half the risk of dying from the flu or pneumonia compared to those who do not meet either goal. rice field.
Important facts:
- A study found that meeting a weekly cardio goal reduced the risk of dying from the flu and pneumonia by 36%.
- Regular aerobic exercise, even less than the recommended 150 minutes per week, significantly reduces the risk of death from flu and pneumonia.
- Achieving a goal of two strength-training sessions per week was associated with a 47% lower risk of death, while seven or more sessions was associated with a 41% higher risk.

Regular aerobic exercise, commonly known as “aerobic exercise”, even at levels below recommended weekly levels, is associated with a significantly lower risk of death from flu and pneumonia, online research suggests. A US study published in British Journal of Sports Medicine.
However, above a certain level, the results suggest that the effects may plateau and may be potentially harmful in the case of muscle-strengthening activities.
Adults should get at least 150 minutes of moderate-intensity physical activity per week, or 75 minutes of vigorous-intensity exercise, aerobic exercise, or an equivalent combination, plus at least 2 moderate-to-high-intensity muscle-strengthening activities per week. It is recommended to do it twice.
Sustained aerobic exercise, such as brisk walking, swimming, running, and climbing stairs, will increase your heart rate and make you sweat. Activities that strengthen muscles include using weights and resistance bands. Exercises such as squats, lunges, and push-ups (flexibility exercises). And hard work gardening.
Evidence shows that regular physical activity not only helps you stay healthy and prevent serious illness, but it may also prevent death from flu and pneumonia.
So the researchers wanted to see if specific types and amounts of physical activity were associated with this reduction in risk.
They used responses from 577,909 adults who participated in the National Health Interview Survey (NHIS) representing the United States between 1998 and 2018.
Respondents were asked how often they performed vigorous-intensity aerobic exercise and light or moderate-intensity aerobic exercise for 10 minutes or more. They then asked how often they did strength-building activities.
Each person was then categorized according to how well they met their recommended weekly aerobic and strength training goals. Achieve your cardio goals. Achieve your strength goals. and achieve both goals.
Five levels of physical activity were defined: less than 10, 10–149, 150–300, 301–600 minutes/week, and ≥600 minutes/week of moderate-to-vigorous physical activity. Less than 2, 2, 3, 4-6 sessions and 7 or more sessions of muscle-strengthening activity per week.
Half of the respondents (50.5%) missed either weekly goal. How well they did varied greatly depending on sociodemographic and lifestyle factors, underlying health conditions, and whether they had been vaccinated against influenza and pneumonia.
One-third (34%) were inactive aerobics, and more than three-quarters (78%) reported fewer than two sessions of strength-building activity per week.
During the average 9-year monitoring period, 81,431 participants died. Of these deaths, 1,516 are believed to be due to influenza and pneumonia.
People who meet both recommended weekly physical activity goals have almost half the risk of dying from influenza or pneumonia compared with those who do not, given factors that may influence them ( 48%).
Taking into account potentially influencing factors, we found that achieving aerobic exercise goals alone reduced risk by 36%, whereas achieving strength goals alone did not significantly differ in risk. .
In terms of quantity, 10 to 149, 150 to 300, and 301 to 600 minutes of aerobic exercise per week were associated with a 21%, 41%, and 50% reduction in risk compared to no activity, respectively. However, no additional benefit was seen beyond 600 minutes per week.
“nevertheless [10-150 mins/week] “Although often classified as ‘insufficient’ because it falls below recommended duration, it may provide health benefits compared to inactivity,” the researchers suggest.
For muscle-strengthening activities, achieving the twice-weekly goal was associated with a 47% lower risk compared to less than two sessions per week, but seven or more sessions was associated with a 41% higher risk.
“It’s beyond the scope of this study, but there are plausible explanations.” [for this dichotomy] They range from inaccurate responses (such as reports of occupational physical activity that may not provide the same protective effects as leisure time physical activity) to the hemodynamic effects of frequent high-intensity exercise. [muscle strengthening activity]’ explains the researchers.
Because this is an observational study, we cannot pinpoint a cause, and the researchers acknowledge various limitations.
For example, this study was based on individual memories and memories at a point in time. The NHIS survey only recorded leisure-time physical activity of 10 minutes or more and did not distinguish between light and moderate-intensity activity.
Nonetheless, the researchers concluded, “Efforts to reduce mortality from influenza and pneumonia in adults will focus on reducing the frequency of aerobic exercise and increasing the frequency of achieving twice-weekly strength-strengthening activities.” It is possible,” he concludes.

“Leisure-time physical activity and mortality from influenza and pneumonia: a cohort study of 577,909 US adults.By Bryant J. Webber et al. British Journal of Sports Medicine
overview
Leisure-time physical activity and mortality from influenza and pneumonia: a cohort study of 577,909 US adults.
the purpose
To investigate the association between leisure-time physical activity and death from influenza and pneumonia.
method
Mortality was followed to 2019 from a nationally representative sample of US adults (18 years and older) who participated in the National Health Interview Survey from 1998 to 2018. Participants were classified as meeting both physical activity guidelines if they reported 150 minutes or more of physical activity per week. Aerobic physical activity equivalent to moderate intensity and her strength-strengthening activity twice or more per week. The participant also divided him into five categories based on the amount of self-reported aerobic and strength-training activity. Mortality from influenza and pneumonia is defined by the International Classification of Diseases, Tenth Edition, Revision Codes J09-J18, as having underlying causes of death recorded in national mortality indices. Mortality risk was assessed using Cox proportional hazards, adjusting for sociodemographic and lifestyle factors, health status, and influenza and pneumococcal vaccination status. Data analyzed in 2022.
result
Of 577,909 participants followed for a median of 9.23 years, 1,516 deaths from influenza and pneumonia were recorded. Participants who met both guidelines had a 48% lower adjusted risk of influenza and pneumonia compared with those who did not meet either guideline. 10–149, 150–300, 301–600, and >600 min of aerobic exercise per week compared with no aerobic exercise reduced risk (21%, 41%, 50%, 41% ). Compared to doing muscle-strengthening activities less than twice a week, there was a 47% lower risk for two times a week and a 41% higher risk for seven or more times a week.
Conclusion
Aerobic exercise, even at amounts below recommended levels, may be associated with reduced mortality from influenza and pneumonia, and muscle-strengthening activity showed a J-shaped relationship.
