Why does pulse rate increase after exercise?

Have you ever wondered why your heart starts racing after a 30-minute jog or an intense workout? Do not fret, my dears! We are here to help you understand what happens inside your body during exercise and why that affects your pulse rate.

The Role of the Heart

Let us start by identifying what our heart does for our bodies before we delve into what it does during exercise. Our heart pumps blood carrying oxygen and nutrients throughout our bodies. It works tirelessly 24/7 to ensure all parts of our systems get enough energy so that they can function correctly (most times).

What is a Normal Pulse Rate at Rest?

Typically, when we are relaxed, breathing slowly, and not exerting any energy whatsoever (I know – this is hard to believe isn’t it), an adult in good health will have the following average resting pulse rates:

  • Men: between 60 to 100 beats per minute
  • Women: between 60 to 90 beats per minute
  • Children: according to their age

A low resting heartrate indicates efficient cardiovascular performance as less strain is placed upon the pumping system of arterial circulation. Hence if yours falls within these ranges’ sweet spot’, then honey child – You’re in luck!

But hold up there cowboy! Once exercise kicks in (brace yourself) heartbeat changes significantly from those calming ‘sips on martini’ tones!

Changes During Exercise

The American College of Cardiology reports that every time we engage in moderate activity like running or cycling; muscle cells work harder beyond normal levels causing a sudden increase in demand for oxygen(O2). Hence the inclusion of aerobic exercises has proven hugely beneficial (and let’s face it everybody could do with working out now!).

In other words Sugarplums when more Oxygenated blood demands arise, Your Dearest Heart receives increased signals from brain asking it to work harder, THAT’s why your rate rises!

To meet this increased oxygen demand during exercise and metabolic activities, the respiratory and cardio-vascular system collaborates to elevate O2 delivery by increasing heart rate promptly. These two systems cooperate in supplying more blood as they regulate the pulse rate above our resting level while also ensuring that enough quantities reach areas of higher energy requirements.

In simpler terms, when you exercise – your body needs more oxygen than normal when at rest, so your heart pumps faster to get oxygen-carrying blood flowing around quickly (obviously).

Cardiovascular System At Work

The cardiovascular system is wholly involved when we engage in an activity like a light stroll or pushing weights at the gym. The simple act of walking briskly can trigger muscle cells into hyperactivity mode.

Again let us break it down Jellybean; As muscles contract repeatedly (which seems like good fun🤸‍♀️), it requires a steady supply of both nutrients & Oxygen so similar messaging gets sent from brain to accompanying connected network with The Dearest Heart Being told: ‘Hey girl! Pump Faster!’ (Doctor Jargon there😜)

While engaging in demanding physical activities such as running, cycling or high impact Zumba classes (GO on Girl! Shake what ya mama gave ya 💃); here is how this process within our bodies works:

  • Glycogen stored within liver& intestines breakdown glucose for readily useable fuel.
  • With Exercise stimuli receivedthe Adrenal Gland Will activate fight/flight responses causing noradrenaline release throughout CNS + PNS️⁣
  • Noradrenaline binds receptors present on tissues such as Heart, Vessels & Bronchi.
  • This causes smooth stressed walls surrounding arterioles and ​precapillary sphincters​ ⁣to relax⬇️Resistance ends up decreasing allowing for optimal Blood flow⁣.
  • Sufficiently Supplied Oxygenated blood is delivered to active muscle tissues that receive enhanced oxygen consumption & metabolic waste removal!

You feeling Dr. Frankenstein now? I KNOW RIGHT!!! We love it too!

The Role of the Autonomic Nervous System

Beyond the scope of our usual Doc visits, allow us to demonstrate how Our Dearest Heart rate increases during exercise due partly because of your autonomic nervous system (Sympathetic Division specifically); in simpler terms – when you are being a ‘fit-loving-machine.’

Do not worry my sweet darlings! A rough day at work, chasing deadlines or driving through rush hour traffic won’t trigger this change in heartbeat (unless you’re running form bad guys like superman).

It takes a more demanding physical activity-like one which challenges your current fitness level and restricts excess O2 supply-to elevate pulse rates noticeably. So next time think-twice before slamming 3 beers down.

Once an individual engages in such activities, vital signs change notably as their heart speeds up and starts beating faster than resting times. At this point sympathetic send messages out along nerve pathways activating energy pathways present within them by stimulating gland response throughout circulation.

This release culminates into Noradrenaline Secretion from Adrenal Medulla & CNS structures causing chains reaction effects, including aiding cardiac tissue excitation features; hence explaining why we see increased speed around cardiovascular process/muscle cellular energy processes in effect providing optimal fuel burning efficiency⁣🤯!

Fitness Levels Impact on Pulse Rate

If you have ever sat around watching Oprah (our beloved momma), then chances are she hit upon discussing Fitness levels sometime amidst her subtle shade throwing over Male-dominant Industries/Politics remits etc.

For those who didn’t catch that particular airing, let us illustrate and how Fitness levels may impact the rate at which your pulse increases. (You’d rather engaging in a fitness regime that can easily surpass Mama O’s Ok).

  • Physically active individuals i.e., Anyone who has regular exercise will experience low resting heart beats due to the enhanced efficiency of energy production.
  • The more stamina levels people tend to have; also means decreased neural input requirements into Cardiovascular function explaining why athletes / long-distance runners per se normally fall on lower-side range within normal blood pressure measurements!

Now all our fit aristocrats out there know why their hearts act quicker than others do during physical activity.

Post-Exercise Heart Rate & Returns

As always my loyal Subjects! We do not just give you part of an understanding but delve deeper through explaining what happens to Pulse rates after workout session ends when we slow down back to rest mode.

After any intense physical activity where sweat beads race down temples or for some appears like they are about drowning 👀💦in own perspiration (not mentioning names), REST man 🙇‍♀️🙇‍♂️ must ensue as immediate soothing practices occur helping maintain adequate oxygenation supply reaching important components in need.

This is called Recovery or relax phase. In this stage (And maybe I’m just biased here) 😅, You might feel inclined towards More caffeine or chocolate before Googling ‘How Long Before My dream Adonis/Aphrodite figure catches up with me’ 😉

Few moments pass by and senses start calming again at this time, nerves slowing heartbeat against circulation requests shutting adrenaline releases off putting heart/pulse rate slowly returning close to pre-workout times.

This balancing inside our bodies allows resting pulse rates gradually decreasing reducing demand stress from Dearest Heart; thus ensuring it never wears-down whilst maintaining stable readings post-workouts⌛!

I don’t mean scented candles btw, that’s just for added luxury. You’re welcome 😉

Factors Affecting Pulse Rate Increase during Exercise

Various Elements can affect how our hearts behave correctly while we perform physical activities:

  1. Age: Mature individuals may respond differently to younger ones- reduced energy levels in due regard.

  2. Gender: Research indicates differences between female VS male Rest and workout rates.

3.Medications taken such as blood thinners, anesthetics or even prescription weight-loss pills influence pulse rates greatly so always check with your GP if on any medication beforehand especially if you are about release your inner lovefool at the gym.

In summary folks(Yes already), We Have Learned Alot! While The human body can inspire efforts to test ingenious boundaries of what is capable physically – at core remains a reliable cardiovascular system which will vigorously fire-up @every time regardless of whether we prefer it chillin out by oceanside sipping away corona or engaging aerobics routine!

Take care sugar-cakes 💜& remember #StayHealthy 🙌🏽💖😉
