Q & A

What happens to muscles when we stop using them for a period of time?

When muscles are not used, they become inefficient and ineffective. If we return to the activity after a break, we experience soreness because our muscles lose their conditioning. However, muscle memory helps regain strength more quickly once we restart.

Why is sitting for long periods considered harmful?

Sitting for long periods is compared to smoking in terms of health risks. Research suggests that prolonged sedentary behavior can negatively affect health, leading to risks like heart disease, obesity, and other chronic conditions.

What are the benefits of participating in group physical activities?

Group physical activities can make exercise more enjoyable and foster accountability. Exercising with others helps people stay consistent, as they feel responsible for showing up, and it often leads to social bonding, making it feel less like a chore.

How does exercise improve mental health?

Exercise releases endorphins and other hormones that help improve mood, reduce stress and anxiety, and enhance mental focus. It has been shown to improve sleep and overall cognitive function, which can also benefit memory and reduce the risk of mental health issues.

What specific exercises are beneficial for older adults?

Weight-bearing exercises like walking or jogging can improve bone health, while low-impact exercises like walking are good for those with joint issues like arthritis. Group exercise programs are also beneficial for social interaction, and exercises can be modified to suit older adults' physical needs, such as chair exercises.

How can regular physical activity help prevent chronic conditions like heart disease, diabetes, and obesity?

Regular physical activity improves heart function by making it more efficient and helps maintain a healthy body weight, which lowers the risk of heart disease, diabetes, and obesity. It can also enhance insulin sensitivity, which helps regulate blood sugar levels.

What is the recommended amount of aerobic activity for adults?

Adults should aim for at least 150 minutes of moderate-intensity aerobic activity per week, such as walking, running, swimming, or cycling. This can be broken down into 30 minutes of exercise five days a week.

How does strength training benefit overall health?

Strength training helps build and maintain muscle mass, which boosts metabolism. It is recommended to do strength exercises at least two days a week, but not on consecutive days, to allow the muscles time to recover.

Why is flexibility training important, and how often should it be done?

Flexibility training helps prevent injuries and maintain joint health. It is recommended to engage in flexibility exercises at least five days a week, which can be incorporated as part of a warm-up or cool-down routine.

What is the recommended exercise duration for individuals trying to lose weight?

For weight loss, it is recommended to engage in 300 minutes of moderate-intensity aerobic exercise per week. Higher-intensity exercises can also achieve similar results in less time.

🧠 Exercise and Mental Health Improvement

Regular exercise contributes to better mental health by releasing endorphins and improving sleep and focus. It can help reduce stress and anxiety, which are key factors in mental health issues. Exercise is also beneficial for memory, particularly in older adults. The speaker emphasizes that exercise can boost both mental and physical health, improving memory function and overall well-being.

🏋️‍♂️ Adapting Exercise for Older Adults

Older adults face specific challenges, such as declining bone health due to insufficient calcium, vitamin D, and lack of weight-bearing exercise. Exercises like walking or jogging are beneficial for maintaining bone health, while low-impact activities help those with arthritis. Modifications like chair exercises are recommended for older individuals at risk of falling. Group exercises in assisted living facilities make exercise enjoyable and safe, fostering social interaction and participation in physical activities.

💓 Physical Activity and Chronic Disease Prevention

Heart disease and cancer are leading causes of death globally, but regular exercise can help prevent these conditions by improving cardiovascular health. The heart becomes more efficient, leading to better blood circulation. Exercise also reduces the risk of some cancers and helps manage obesity, a factor linked to various chronic diseases. Additionally, exercise plays a role in preventing and treating conditions like diabetes by improving insulin sensitivity.

🏃 Recommendations for Aerobic and Strength Training

General recommendations include at least 150 minutes of moderate aerobic activity per week. Activities like walking, swimming, and cycling can be incorporated into daily routines. Strength training twice a week is essential for building muscle, which boosts metabolism. Flexibility training, often neglected, is equally important, as it helps prevent injuries and improves joint health. The speaker emphasizes including flexibility exercises in warm-ups or cool-downs for better results.

⚖️ Maintaining a Healthy Body Weight and Metabolism

For weight maintenance, 150 minutes of aerobic exercise per week is the minimum, while 300 minutes is recommended for weight loss. Muscle mass is important for increasing metabolism, as more muscle burns more calories. The speaker discusses the trend of seeking quick fixes for faster metabolism but stresses that building muscle through weight training is the most effective and natural way to achieve this.

Keywords

💡Muscle memory

Muscle memory refers to the body's ability to regain strength and performance more quickly after a period of inactivity. The speaker discusses how, after taking a break from physical activity, the body can feel sore when resuming exercise, but previously trained muscles 'remember' and regain their ability faster. This concept is essential to understanding how consistent physical activity builds long-term benefits.

💡Sedentary behavior

Sedentary behavior describes prolonged periods of inactivity, such as sitting for long stretches, which can have harmful health effects. The speaker compares sitting for extended periods to the risks of smoking, emphasizing how physical inactivity negatively impacts overall health. This highlights the need for regular movement to maintain well-being.

💡Group exercise

Group exercise involves physical activities performed in a group setting, which provides social and motivational benefits. The speaker emphasizes that exercising in a group can make the experience more enjoyable and promote accountability, helping participants maintain a consistent fitness routine. Group activities, such as fitness classes, help build a community and encourage regular participation.

💡Mental health

Mental health refers to an individual’s emotional and psychological well-being. The speaker links exercise to improved mental health, citing how physical activity releases endorphins and hormones that reduce stress and anxiety, enhance sleep quality, and improve mood. Exercise is presented as a method to combat the mental health crisis by fostering a positive mindset and reducing cognitive decline.

💡Bone health

Bone health is the strength and density of bones, which can deteriorate with age, leading to conditions like osteoporosis. The speaker notes that older adults, who may lack sufficient calcium and vitamin D, are at greater risk for poor bone health. Weight-bearing exercises, such as walking, are recommended to help improve bone strength, particularly for elderly populations.

💡Chronic conditions

Chronic conditions refer to long-lasting diseases like heart disease, diabetes, and obesity. The speaker discusses how regular physical activity can help prevent or manage these conditions by improving heart function, regulating body weight, and enhancing insulin sensitivity. Exercise is positioned as both a preventative measure and a form of treatment for chronic diseases.

💡Aerobic exercise

Aerobic exercise, or cardio, involves activities that increase heart rate and improve the body's oxygen use, such as walking, running, or swimming. The speaker advises getting at least 150 minutes of aerobic activity per week to maintain health, while 300 minutes is recommended for weight loss. Aerobic exercise helps maintain heart health and overall fitness.

💡Strength training

Strength training involves exercises designed to build muscle mass, improve metabolism, and enhance strength, such as weightlifting.

Transcripts

I was just texting my colleague I have a

t suppos to the students at 1030 so I

was

the L it Theory so if we're not using

our muscles we can lose them and so um

and probably many of us have experienced

this before we used to do an activity

and then we take some time away and then

when we go to do that activity again we

get really sore and so I think that

tells our bodies were created to move

when we're not using those muscles then

they become inefficient ineffective and

then when we go to try to do that kind

of exercise or movement again then we

get really sore from it now the good

thing is once we kind of train our

muscles and we have that muscle memory

it comes back quicker and if we've never

done those types of movements before but

and there's been a ton of research on

sedentary Behavior and how that can put

us at health risk there's been some

reports calling sitting the new smoking

so sitting long periods of time can kind

of effects on our as we found that

smoking cigarettes can have so a lot of

the research is pointing Us in the

direction that our bodies were made to

move we should be moving frequently

throughout the day not sitting for long

periods of time

oh

yeah got it yeah

okay

I okay

now explain the benefits of

participating in group

activities physic activity yeah so group

exercise uh can first of all it can be

more fun uh just getting to exercise

with other people and there's this

accountability piece which is

really when it comes to exercising in

groups or at least with a partner or a

friend um because exercise sometimes can

be daunting or um boring to some uh and

so it just gives that added piece of

accountability knowing somebody's

counting on you to be there um you're

more likely to have a schedule and

you're just more likely to go do that

exercise uh we offer here at uh our

Wellness Center like group fitness

classes uh where you know you go and you

have a large exercising together and

that group starts to become friends and

you know if somebody misses the class

they're calling them up or U sending

them a message where were you we missed

you today and so then that brings that

individual back to the group uh and so

it just seems like when you have a

partner or a group that socialization

aspect can really help people to stay

accountable to exercise it's true it's

true became becomes a family kind of

now tell me a little

bcise onal and

how quity of Life yes so there has been

a lot of research recently on this area

and here in the United States we have a

major Mental Health crisis happening and

so we're constantly looking for ways to

improve mental health and uh exercise

has been proven to be one of those

methods um you know um the endorphins

the hormones um that are released when

you're exercising uh can just help you

to have more of a positive mindset you

sleep better um and you're just more

mentally focused and so it also helps

with Stress and Anxiety which we know

can lead into some of the issues with

mental health and so um just exercise

overall can help uh improve that area uh

and so there's evidence suggesting that

that's just one way one thing that we

can do to help improve our mental health

and it helps with memory as well which

we see a lot of older individuals who

are struggling with memory issues and so

U by exercising uh keeping the brain

active keeping the body active we can

help with those areas it's true it's

true now tell me um you tell me

aref ofal

and how can we adapt exercise programs

to meet their needs um since they have

special needs sometimes yeah so for the

older populations probably one of the

biggest challenges is bone health as we

get older um so we know that a lot of

older adults um struggle to they're not

maybe eating enough calcium getting

enough vitamin D which is U mainly from

the Sun so older adults don't tend to

spend as much time outside um they're

not as active and so then their bone

health starts to suffer and so the main

things that we can do to to um impact

our bone health is one we is

weightbearing exercise so that's

exercise where you are uh carrying your

body weight so if you're walking or

jogging now swimming and cycling those

are good exercises but they're not

weightbearing right you're not holding

your weight so it doesn't have the

impact on your bone health um so we want

older adults doing types of activities

um making sure they're getting enough

calcium vitamin D so those that can

really help impact uh their bone health

and then um in terms of uh finding

exercises now we also have a lot of

older adults that suffer from like

arthritis which is hard on the joint so

that does make weightbearing exercises a

little more challenging so we want to go

with ones that aren't as high impact so

like low impact just you know walking be

a great exercise and then um we want

them to exercising in groups can be

really good so uh that could be helpful

for them so they have that stimulation

you know being in a group

socialization uh with their exercise and

maybe even doing like we could do

modifications where they're sitting in a

chair so that they can still participate

in exercise but if they're at risk of

falling or something like that then they

would be more safe lots of modifications

we can do for exercise um but we want

older individuals uh to participate and

making it fun sometimes is great I know

a lot of uh like assisted uh care

Assisted Living type facilities will

have group exercise programs and they

just make it fun they have them play

games um so that again it doesn't seem

like exercise to them they're just just

doing something fun with friends right

and having a good time yes

let's talk about some uh chronic

conditions and uh such as heart disease

diabetes obesity how does regular

physical activity could help in

prevention and treatment yeah so the

leading cause of death throughout the

world is heart disease um followed by

cancer and so those are uh two that we

talk about most here in the US but also

throughout the world those are the

leading causes of death and so um we

have found that exercise can be very

impactful um for heart disease uh it

helps U Move um the the blood and

nutrients throughout the body more

effectively um the heart becomes more

efficient it uh pumps more effectively

it's not going to take small beads it's

going to take large beads and um you

know distribute the the blood and

nutrients more effectively throughout

the body and so uh if we're looking over

a long period of time the just the heart

health is going to be more effective and

uh and so also uh the exercise can help

with not all cancers but it can help um

with uh reducing the risk of some types

of uh Cancers and also related to like

obesity so obesity can be um linked to

both uh to all chronic diseases really

so um by moderating our body weight

which exercise can really help with that

to maintain of a helpful body weight

over time so we can reduce our risk of

uh these types of chronic diseases

including diabetes as well um so our

blood cells can or our um insulin our

cells will be more receptive to insulin

uh so that's another benefit of uh

exercise and so the neat thing about

exercise is that it can play both a

preventative role and then if somebody

is diagnosed with the it also can we can

use exercise for treatment as well um so

both um are effective um but we want to

go the preventative route if possible so

maintaining good health maintaining a

healthy body weight um is one of the

things you'll the American um uh heart

disease or the American Heart

Association uh the American Institute

for cancer research uh they both talk

about um eating health maintaining a

healthy body weight and also exercising

regularly uh can reduce your risk of

heart disease cancer and many other

chronic

diseases well now let's talk about the

we have a lot

of different age groups

[Music]

that we participate in aerobic

exercise um the general recommendation

that we talk about is at least getting

150 minutes a week of aerobic activity

at moderate intensity and so you know

that's like 30 minutes five days a week

so trying to get that kind of exercise

on a regular basis is really important

so those are exercises that like really

get your heart going uh walking running

swiming

cycling maybe even playing some sports

or attending like a group fitness type

of class um strength training is really

important so that we can build muscle um

so the one thing about building muscle

mass it actually can help our metabolism

he this is a very trendy thing um is uh

how do you get a faster metabolism right

everybody wants to take some sort of

Miracle uh pill to to boost their

metabolism or eat something that's going

to help their

well building muscle is the one thing

that can change our metabolism because

we burn more calories when we have more

muscle mass um so Weg training is really

important um helps to build and or

maintain our muscle mass um and so that

can have a lot of health benefits so at

least participating in that kind of

exercise at least two days a week and we

do recommend not doing it on consecutive

days so you want to exercise those

muscles and give them some rest um but

that can really help us to to build um a

good foundation with our our muscle mass

and then the one that's forgotten the

most is flexibility I'm not going to lie

that's the one I need to work on the

most um I think people don't believe in

the power of that yes seems like a more

relaxing correct but it's so important

it can actually help prevent injury um

when our muscles become too tight um

then we're more prone to injuries and

just having issues like with our joints

and such so you know spending some time

and at least five days a week is the

recommendation uh to try to include some

flexibility training and I tell people

include it as a warmup or a cool down to

the exercise you're already doing so

just try to take those few extra minutes

to really get that flexibility training

in it's not that

hard at least 15 of aerobic yes that's

the minimum recommendation is at least

15 yeah of course 300 minutes a week is

what's recommended for weight loss which

we know there's a lot of individuals

trying to lose weight um twoth third of

Americans are overweight or obese so and

a lot of them are actively trying to

lose weight so it's 300 minutes a week

if you're trying to lose weight but just

for maintenance

is50 that's the minimum and most people

don't even get that much you can do 75

minutes a week if you want to do a

higher level of so we're finding that

you can do higher intensity exercise for

less time um and so that's an option as

well which we can see some of the same

results see what better right okay I

think this is it for now
