The Cardiovascular Benefits of Running
Strengthening the Heart Muscle
Running is a potent cardiovascular exercise that fortifies the heart muscle. Engaging in regular running sessions enhances the heart’s efficiency, enabling it to pump blood more effectively throughout the body. This improved circulation ensures that oxygen and nutrients are delivered more efficiently to various tissues and organs, promoting overall health.
Lowering Blood Pressure and Cholesterol Levels
Consistent running has been shown to reduce systolic and diastolic blood pressure, mitigating the risk of hypertension—a major contributor to heart disease. Moreover, running positively influences lipid profiles by decreasing triglycerides and increasing high-density lipoprotein (HDL) cholesterol, thereby reducing arterial plaque buildup and enhancing vascular health.
Enhancing Vascular Function
Regular running promotes endothelial function, which is crucial for maintaining vascular health. Improved endothelial function leads to better vasodilation, ensuring that blood vessels can expand and contract efficiently. This adaptability is vital for regulating blood pressure and ensuring adequate blood flow during varying physical demands.
Mental Health and Running
Alleviating Stress and Anxiety
Running serves as a natural stress reliever. The rhythmic nature of running, combined with the release of endorphins, helps in reducing stress levels and alleviating symptoms of anxiety. This mental clarity and emotional upliftment contribute to overall heart health by reducing stress-induced cardiovascular strain.
Enhancing Cognitive Function
Engaging in regular running sessions has been linked to improved cognitive functions, including memory, attention, and executive functions. This cognitive enhancement is attributed to increased blood flow to the brain and the release of neurotrophic factors that support neuronal health.
Getting Started: From Couch to 5K
Setting Realistic Goals
Embarking on a running journey requires setting achievable goals. Starting with short distances and gradually increasing the mileage helps in building endurance and prevents injuries. Utilizing structured programs like the “Couch to 5K” can provide guidance and motivation.
Importance of Proper Footwear
Investing in appropriate running shoes is crucial. Proper footwear provides the necessary support and cushioning, reducing the risk of injuries and enhancing running efficiency.
Incorporating Warm-Up and Cool-Down Routines
Incorporating dynamic warm-up exercises before running prepares the muscles and cardiovascular system for the workout. Similarly, cooling down with static stretches post-run aids in recovery and maintains flexibility.
Does RUNNING make You LIVE Longer?
YES, according to an observational study published in JACC in 2014, which looked at associations of running with all-cause (any death) and cardiovascular mortality (death related to heart disease) risks.
The authors included 55 137 participants aged between 18 and 100 years, with mean age of 44.
They concluded after 15 years (mean)of follow-up:
▪️24% of participants were engaged in running in the study population
▪️in comparison to non-runners, runners had 30% and 45% decreased adjusted risks of dying of any cause and dying of a heart disease, respectively
▪️3-year life expectancy benefit was noted
▪️even 5-10 minutes per day and slow speed <6mph were associated with markedly reduced risk of death from all causes and cardiovascular disease
▪️’this study may motivate healthy but sedentary individuals to begin and continue running for mortality benefits’

How much RUNNING is enough to make You LIVE LONGER?
Even 50mins of running a week reduces the RISK of DEATH by 27% from all causes, according to a meta analysis, which included over 230,000 participants and was published in British Journal of Sports Medicine.

In 2015 another study published in JACC, showed that 1 to 2.4 hrs of jogging per week was associated with the lowest mortality and the optimal frequency of jogging was 2 to 3 times per week. The study also concluded that light and moderate runners have lower mortality than sedentary non joggers, whereas strenuous runners have a mortality rate not statistically different from that of the sedentary group.

Is EXERCISING in areas with HIGH AIR POLLUTION harmful to Your Heart?
Physical Activity, including running, in areas with high air pollution is a two-edged sword – suggests a study, which was published in European Society of Cardiology in March 2021.
– The researchers examined the association of the combined effects of air pollution and changes in physical activity with cardiovascular health in a large study, consisting of almost 1.5 million participants (age 20-39 years).
– They concluded that reducing physical activity in individuals exposed to low and moderate levels of air pollution may lead to increased risk of cardiovascular disease.
– On the other hand, a large increase in physical activity in an environment with high levels of air pollution may adversely impact heart health too.

Can Jogging reduce CHOLESTEROL levels?
There are several ways to reduce Your blood Cholesterol and one of them is JOGGING, according to a study, published in 2021 in the Journal of the International Society of Sports Nutrition.
Jogging is associated with a reduction of:
⬇️ Tryglicerides (95% CI = 5.9-14.5 mg/dL)
⬆️ Tryglicerides/High-density lipoprotein cholesterol ratio (95% CI = 0.22-0.49)
and
⬆️ Increased level of High-density lipoprotein cholesterol (95% CI = 2.1-3.3 mg/dL)
– It was an observational study, which enrolled 27735 participants and was published in the Journal of the International Society of Sports Nutrition in May 2021.
– Regular jogging was defined as 30 mins of ‘exercise’ three times a week.
The author concluded: ‘Regular jogging was not only associated with an increased level of HDL-C, but also the only one exercise associated with decreased level of TG and TG/HDL-C ratio. Nonetheless, jogging may be difficult to engage in for subjects with limited exercise capacity. We here found that swimming, dancing, and cycling are also significantly associated with an increased level of HDL-C. People who are seeking exercise to improve their lipoprotein-lipid profiles can have other choices now’.

Does EXERSICING more than recommended make You LIVE LONGER?
Yes, according to a study described below.
Lower risk of dying was shown to be associated with:
– 150-299 mins per week of Moderate Physical Activity or
– 300-599 mins per week of Vigorous Physical Activity or
– A time combination of the above.
Moderate Physical Activity (3-6 METs) includes: walking very briskly, cycling, cleaning such as mopping or washing windows and badminton or tennis doubles.
Vigorous Physical Activity (>6 METs) includes: Basketball, Football, Hiking, Jogging, Cycling fast or even shovelling.
It was a large study, which included 116 221 adult participants and follow up lasted 30 years.
It was published in Circulation in July 2022.
Participants, who performed VPA (75-149 min per week) versus no VPA had lower overall mortality (HR 0.81), lower non-cardiovascular mortality (HR 0.85) and lower cardiovascular mortality (HR 0.68).
Individuals with weekly MPA of 150-299 mins per week showed reduction of overall, cardiovascular and non-cardiovascular risk of dying by 19-25%.
However, people who exercised more than that, as mentioned at the beginning, VPA of 150-299 mins a week and MPA of 300-599 minutes a week, had lower mortality risk of 2%-4% and 3%-13%, respectively.
Exercising beyond that showed no further benefit or harm.

Does exercising in your early adulthood matter 20 years later?
▪️Starting and continuing heightened cardiorespiratory fitness at an early adult age may decrease risk of dying and developing cardiovascular disease, claims this study ➡️ published in the JAMA Network Open journal in February 2023.
▪️4804 participants age 18 to 30 (mean age 24.8, 56% females) were recruited in 1985 and 1986. They were assessed at baseline and followed up ever since.
▪️ At baseline, even 1 minute of increased fitness was associated with a lower risk of all-cause death.
▪️Similarly, retained fitness through year 20 was linked to reduced risk of dying from any cause.
▪️In addition to this, similar association was observed in terms of fatal and nonfatal Cardiovacular Events.
▪️These results come from an ongoing Coronary Artery Risk Development in Young Adults (CARDIA) study.
▪️The authors concluded: ‘This cohort study found that higher early-adulthood respiratory fitness and greater retention of early-adulthood cardiorespiratory fitness throughout midlife were associated with a lower risk of premature death and CVD events. Additional research is needed to clarify the association of cardiorespiratory fitness timing across the life course with risk of clinical outcomes.’
Is EXERCISING in the MORNING better for Your Heart?
▪️The answer is YES, according to this study ➡️ published in November 2022 in the European Journal of Preventive Cardiology.
▪️Study participants who were physically active in late morning had 16% lower risk of coronary artery disease (HR: 0.84, 95%CI: 0.77, 0.92) and 17% lower risk of stroke (HR: 0.83, 95%CI: 0.70, 0.98) in comparison to individuals who were physically active at midday.
▪️Interestingly these effects were more pronounced in female participants.
▪️It was a large trial, which included 86657 individuals with mean age of 61.6, mean BMI of 26.6 and 58% females.
▪️The follow up lasted for 6 years and 3707 cardiovascular events were noted.
▪️The researchers concluded:
‘Irrespective of total physical activity, morning physical activity was associated with lower risks of incident cardiovascular diseases, highlighting the potential importance of chronoactivity in CVD prevention.’

What is the minimum time that you have to exercise vigorously to decrease your chances of dying from cancer or cardiovascular disease?
▪️New study published in October 2022 in European Heart Journal showed that:
– 15 MINUTES per week of VPA was associated with 16-18% lower all cause and cancer deaths.
– 20 MINUTES per week of VPA was linked with 40% lower incidence of cardiovascular deaths.
▪️VPA – Vigorous Physical Activity is defined as 6 or more metabolic equivalents (METs) i.e. running or swimming
▪️ In addition to this, the enhanced benefit on mortality was observed up to 50-57 MINUTES per week.
▪️It was a large study, which included 71893 adult participants (median age 62.5 years, 55.9% females)
▪️ The individuals enrolled in the study wore wrist accelerometers for 24hrs/day for 7 days to measure their physical activity.
▪️The recruitment took place between 2013-2015 and the follow up lasted 5.9 years.
