“Aren’t they a little young for that?”

This is a question I used to hear regularly from parents when I’d recommend strength training for the kids I worked with, whose ages ranged from 6 to 18 years old, in youth sports. During my four years as a strength and conditioning coach, I often received questions from parents about the pros and cons of strength training – that is, training that involves weight-bearing exercises – for children.

Some of the most common questions: Is strength training safe for children and adolescents? At what age is it appropriate for them to begin strength training? What are the benefits of strength training for this age group? Is strength training beneficial even for kids who are not involved in organized sports?

Simply put, it is safe and appropriate for kids of all ages to perform strength training.

I am an exercise physiologist, certified strength and conditioning specialist and certified performance and sport scientist. My research focuses on how muscle develops from childhood to adolescence, with the goal of understanding how young people can get the most benefit out of exercise training programs, particularly strength training programs.

My experience and research has shown that strength training can help to improve sports performance for youth, and that there are significant health benefits for youth participating in strength training beyond sports performance.

Safety first

The question I receive most often, for good reason, is whether strength training is safe for youth. In a study examining injury rates in numerous sports, researchers found that, when done correctly, strength training had a lower risk of injury than nearly all other sports. This is not only true for adults but also for children.

That being said, it is important to consider a young person’s emotional maturity before handing them a dumbbell. During my career, I have designed and implemented strength training programs for kids of all ages, even as young as 6 years old. But not every child in that age range is ready for strength training. For their own safety, participants need to be emotionally mature enough to listen to and follow instructions so that they don’t hurt themselves. For some kids, that’s as early as age 6, while others may not be ready until they are a few years older.

Because correct technique is key to doing these exercises safely, it is important that strength training programs for children be designed and implemented under the guidance of a qualified trainer or coach. This means someone with valid credentials and who has received higher education in exercise science.

It’s also important to seek out professionals who use scientific evidence to back up their training programs and philosophies.

The benefits of strength training

Research has shown that stronger muscles in kids reduce the likelihood of injuries during various types of activities.

One study we conducted found that lower muscle strength and size could lead to lower performance during different activities kids typically engage in, such as running and jumping. Not only this, but kids with lower strength tend to have worse neuromuscular efficiency, which means that they are not as proficient at activating their muscles. This translates to using more energy and feeling more worn out when they’re physically active.

While it’s easy to see how strength training is important for youth who play sports, there are also incredible health benefits for kids who may not be into organized sports. Studies have shown the positive effect that strength training can have on healthy bone development in kids, leading to a lower likelihood of fractures. Research has also shown that strength training in kids can have a positive influence on psychological well-being and academic performance.

Strength training can also affect overall health and well-being as it relates to childhood obesity.

Obesity rates in children and adolescents have been rising for decades. Previous research has suggested that youth who are categorized as obese tend to have lower muscle strength than those considered normal weight. Not only this, but other research has found that youth who are obese may have a greater likelihood of sarcopenic obesity, defined as obesity with low muscle mass and function, which can have significant, negative health ramifications.

Resistance training interventions in youth with obesity have shown to have positive impacts on metabolic health, body composition, psychological health and overall quality of life.

Creating an age-appropriate program

An effective strength training program starts with setting age-appropriate expectations.

Children and adolescents are not miniature adults, and not all young people will adapt to a strength training program the same way. For instance, research shows that during puberty, there are unique differences in how muscle develops in boys versus girls.

Specifically, girls may have more neuroplasticity, which is defined as the brain’s ability to recognize new movements and patterns. This means that they may adapt to more complex movements faster than boys, while boys will see more significant changes when their muscle mass starts increasing with puberty. This doesn’t necessarily mean that girls and boys need vastly different strength training programs. It simply means not all kids will have the same rate of progression for certain exercises.

Taking that into consideration, an age-appropriate program should focus on technique over results. How much weight a child can lift is far less important than teaching them good movement patterns. For example, if a child is having difficulty performing normal pushups, a qualified professional could modify the exercise so they start with wall pushups or incline pushups. This will help that child build good movement patterns and be better for their strength in the long run.

Building off this focus on technique, a good strength training program for youth should progress from simple movements to more complex movements and lighter weights to heavier weights, taking into consideration that not all youth will adapt at the same rate.

Focusing on the long term

Obviously, most kids won’t grow up to be professional athletes, but every child can develop athleticism. A good strength training program for kids will set them on a trajectory to a healthy lifestyle from childhood to adolescence to adulthood.

Research shows that beginning exercise in childhood tends to lead to continued exercise habits in adulthood. For this reason, the National Strength and Conditioning Association, a leading organization in the field of strength and conditioning and exercise science, has encouraged a focus on improving training habits in childhood that can then be maintained into adulthood for overall better health and well-being.

Starting young with an age-appropriate strength training program can help kids develop good movement patterns and incorporate exercise into their routine, which can have lasting benefits for their health into adulthood.The Conversation

10 states had abortion measures on the ballot – where they passed, where they failed, and what it all means

Voters in 10 states decided on measures relating to abortion on Nov. 5, 2024, many of which sought to expand access to abortion or expressly recognize a right to abortion in the state’s constitution.

Seven of the ballot measures passed, while three failed. Measures in Arizona, Colorado, New York, Maryland, Missouri, Montana and Nevada were approved by voters, while measures to expand abortion access in Florida, Nebraska and South Dakota went down.

Nebraskans voted on two competing measures. The one that passed enshrines the current law that allows elective abortions until 12 weeks into the state constitution. The measure that failed would have extended elective abortions until fetal viability, about 24 weeks.

Abortion across the US

Since the Supreme Court decided Dobbs v. Jackson in 2022, ending a federal right to abortion, states have moved in multiple directions. Abortion laws across the U.S. have changed a great deal in the past two years and vary widely.

Some states still allow abortion but only earlier in pregnancy. Nebraska, for example, allows abortions before 12 weeks.

Some states expanded or wrote into law abortion access. Colorado, eight other states and Washington, D.C., allow elective abortions until birth, without any restriction on gestational age.

Other states, like Texas, sought to restrict abortions once a heartbeat is detected at around six weeks.

All of this variation can be confusing. And, as a health law professor, I know how important it is for people to understand the law so that pregnant women, or women who have had a miscarriage, are not fearful of seeking medical care.

What abortion laws regulate

The most important thing to understand, in my view, is that laws which regulate abortion apply to actions that health care providers take to intentionally terminate a pregnancy.

Laws designed to limit abortion procedures are not meant to block access to care for women who are seeking treatment for a miscarriage or ectopic pregnancy.

Abortion laws do not penalize or criminalize women seeking an abortion; they regulate health care providers. This is true even in states with restrictive abortion laws, such as South Dakota, Indiana, Texas and Alabama.

Regulating physician conduct is not new – nor is it unique to abortion laws. Very specific laws regulate physician conduct with severe, and even criminal penalties, for possibly fraudulent billing, disregarding federal privacy rules or inappropriately prescribing medication.

Colorado enshrines a right to abortion

In Colorado, Proposed Initiative 89 passed with 62% of the vote. The initiative added language to the state constitution that expressly recognizes a “right to abortion.”

In 2022, the Colorado Legislature codified access to abortion without limits to gestational age. The initiative adds the provision to the state constitution, which makes it a permanent law, so the Legislature cannot amend or modify it.

The initiative also struck language in the Colorado Constitution that prohibited using taxpayer funds to pay for abortions for women with Medicaid or state-sponsored insurance plans. Colorado already requires private insurance to cover the total cost of abortions.

Supporters of the initiative say that allowing taxpayer funding for abortions will stop the “discriminatory and harmful effects” of previous insurance restrictions.

About 38 states prohibit using taxpayer funds for abortion, while some states allow using taxpayer funds for abortions only in cases involving rape, incest or where the woman’s life is at risk.

Florida votes to maintain abortion law

In Florida, Amendment 4, which voters did not pass, proposed a state constitutional amendment to permanently expand abortion access. This measure would have allowed women to obtain an abortion until viability for any reason. It also would have permitted abortion after viability until birth “when necessary to protect the patient’s health.”

The U.S. Supreme Court ruled in 1973 that “health” not only includes a pregnant woman’s physical health, but also extends to considering her age, emotional state or psychological well-being.

Since Amendment 4 did not pass in Florida, the law remains the same.

Florida allows abortion only until six weeks gestation. However, Florida’s law has multiple exceptions, allowing abortions that result from crimes such as rape, incest, domestic violence or human trafficking for up to 15 weeks.

Florida also permits abortion in the first two trimesters in cases where the fetus has a fatal abnormality. Finally, Florida has exceptions that allow abortion for emergencies, or where continuing the pregnancy would pose a threat to the woman’s life or physical health.

Misconceptions about abortion laws

Several articles, including a series in ProPublica, have described cases where women who were pregnant and sought emergency medical treatment suffered complications or death.

The death of any young woman is tragic. However, in my opinion, these cases reflect a misunderstanding of what the law allows, which could make physicians unsure and slow to treat the patient. Some cases may also involve miscommunication, or potential medical mismanagement.

Unfortunately, incorrect or even missed diagnoses are common in emergency rooms, affecting 7.4 million people per year. One in 350 people who had a missed diagnosis suffers serious disability or death.

State laws that regulate abortion do not prevent physicians from intervening to provide necessary or life-saving medical care for women.

Florida’s law plainly says that if there is a conflict between trying to preserve the woman’s life or the fetus’s life, the physician “must consider preserving the woman’s life and health as the priority.”

Florida and Georgia have provided guidance to physicians to clarify what the law allows when treating their patients.

All states – even those with restrictive abortion laws like Texas and Indiana – have exceptions that allow abortion in cases of a medical emergency, or where continuing the pregnancy would pose a risk to the woman’s life or health. In addition, the Department of Justice has stated that people have a constitutional right to travel to seek medical care or abortions in other states from willing providers.

Physicians who feel uncertain can reach out for assistance from a lawyer or find information from their state health department for clarification.The Conversation

Is AI dominance inevitable? A technology ethicist says no, actually

Published

theconversation.com – Nir Eisikovits, Professor of Philosophy and Director, Applied Ethics Center, UMass Boston – 2024-11-08 07:37:00

AI is powerful technology, but that doesn’t mean we should adopt it unquestioningly.

Nir Eisikovits, UMass Boston

Anyone following the rhetoric around artificial intelligence in recent years has heard one version or another of the claim that AI is inevitable. Common themes are that AI is already here, it is indispensable, and people who are bearish on it harm themselves.

In the business world, AI advocates tell companies and workers that they will fall behind if they fail to integrate generative AI into their operations. In the sciences, AI advocates promise that AI will aid in curing hitherto intractable diseases.

In higher education, AI promoters admonish teachers that students must learn how to use AI or risk becoming uncompetitive when the time comes to find a job.

And, in national security, AI’s champions say that either the nation invests heavily in AI weaponry, or it will be at a disadvantage vis-à-vis the Chinese and the Russians, who are already doing so.

The argument across these different domains is essentially the same: The time for AI skepticism has come and gone. The technology will shape the future, whether you like it or not. You have the choice to learn how to use it or be left out of that future. Anyone trying to stand in the technology’s way is as hopeless as the manual weavers who resisted the mechanical looms in the early 19th century.

In the past few years, my colleagues and I at UMass Boston’s Applied Ethics Center have been studying the ethical questions raised by the widespread adoption of AI, and I believe the inevitability argument is misleading.

History and hindsight

In fact, this claim is the most recent version of a deterministic view of technological development. It’s the belief that innovations are unstoppable once people start working on them. In other words, some genies don’t go back in their bottles. The best you can do is harness them to your good purposes.

This deterministic approach to tech has a long history. It’s been applied to the influence of the printing press, as well as to the rise of automobiles and the infrastructure they require, among other developments.

But I believe that when it comes to AI, the technological determinism argument is both exaggerated and oversimplified.

AI in the field(s)

Consider the contention that businesses can’t afford to stay out of the AI game. In fact, the case has yet to be made that AI is delivering significant productivity gains to the firms that use it. A report in The Economist in July 2024 suggests that so far, the technology has had almost no economic impact.

AI’s role in higher education is also still very much an open question. Though universities have, in the past two years, invested heavily in AI-related initiatives, evidence suggests they may have jumped the gun.

The technology can serve as an interesting pedagogical tool. For example, creating a Plato chatbot that lets students have a text conversation with a bot posing as Plato is a cool gimmick.

But AI is already starting to displace some of the best tools teachers have for assessment and for developing critical thinking, such as writing assignments. The college essay is going the way of the dinosaurs as more teachers give up on the ability to tell whether their students are writing their papers themselves. What’s the cost-benefit argument for giving up on writing, an important and useful traditional skill?

In the sciences and in medicine, the use of AI seems promising. Its role in understanding the structure of proteins, for example, will likely be significant for curing diseases. The technology is also transforming medical imaging and has been helpful in accelerating the drug discovery process.

But the excitement can become exaggerated. AI-based predictions about which cases of COVID-19 would become severe have roundly failed, and doctors rely excessively on the technology’s diagnostic ability, often against their own better clinical judgment. And so, even in this area, where the potential is great, AI’s ultimate impact is unclear.

In retrospect, using AI to help diagnose COVID-19 patients was problematic.

In national security, the argument for investing in AI development is compelling. Since the stakes can be high, the argument that if the Chinese and the Russians are developing AI-driven autonomous weapons, the United States can’t afford to fall behind, has real purchase.

But a complete surrender to this form of reasoning, though tempting, is likely to lead the U.S. to overlook the disproportionate impact of these systems on nations that are too poor to participate in the AI arms race. The major powers could deploy the technology in conflicts in these nations. And, just as significantly, this argument de-emphasizes the possibility of collaborating with adversaries on limiting military AI systems, favoring arms race over arms control.

One step at a time

Surveying the potential significance and risks of AI in these different domains merits some skepticism about the technology. I believe that AI should be adopted piecemeal and with a nuanced approach rather than subject to sweeping claims of inevitability. In developing this careful take, there are two things to keep in mind:

First, companies and entrepreneurs working on artificial intelligence have an obvious interest in the technology being perceived as inevitable and necessary, since they make a living from its adoption. It’s important to pay attention to who is making claims of inevitability, and why.

Second, it’s worth taking a lesson from recent history. Over the past 15 years, smartphones and the social media apps that run on them came to be seen as a fact of life – a technology as transformative as it is inevitable. Then data started emerging about the mental health harms they cause teens, especially young girls. School districts across the United States started to ban phones to protect the attention spans and mental health of their students. And some people have reverted to using flip phones as a quality of life change to avoid smartphones.

After a long experiment with the mental health of kids, facilitated by claims of technological determinism, Americans changed course. What seemed fixed turned out to be alterable. There is still time to avoid repeating the same mistake with artificial intelligence, which potentially could have larger consequences for society.The Conversation

Military veterans are disproportionately affected by suicide, but targeted prevention can help reverse the tide

Mounting evidence shows that veterans need targeted suicide prevention services.

America’s military veterans make up about 6% of the adult population but account for about 20% of all suicides. That means that each day, about 18 veterans will die by suicide.

In the U.S., the overall rate of suicide has largely increased since the start of the millennium, but veterans are disproportionately represented among this tragic trend.

Each of these losses affects not only the individual but also their families, friends and co-workers. Thus, working to prevent suicide and its underlying causes is important not only to protect our loved ones but also to foster happier, safer communities.

We are a team of researchers at Arizona State University’s Center for Violence Prevention and Community Safety. We manage the Arizona Violent Death Reporting System, a surveillance system sponsored by the Centers for Disease Control and Prevention and part of the larger national surveillance system that operates in all U.S. states, Puerto Rico and Washington. We gather information on suicides through agreements with the Arizona Department of Health Services, medical examiners and law enforcement.

Assessing risk amid uncertainty

Military veterans range from 18 years of age to more than 100, include both men and women, and represent diverse races and ethnicities. As of 2018, the largest veteran cohort were those who served during the Vietnam War, followed by those who served during peacetime only, the Gulf War and post-9/11 conflicts.

Identifying the true risk of veteran suicide, especially relative to the general population, is a surprisingly difficult task. In past decades, researchers and stakeholders debated about which figures were most accurate, those showing veterans at increased risk or those showing the opposite. Such debates often stemmed from methodological factors.

However, mounting evidence shows that veterans need targeted suicide prevention services, and our data backs this up. From 2015 to 2022, the age-adjusted suicide rates among male veterans in Arizona outpaced those of nonveterans by a factor of 1.49 to 1.88. Put another way, while veterans in Arizona made up only 8.4% of the population in 2022, they represented 20.3% of the state’s suicides, meaning veterans were 2.5 times more likely to die by suicide.

While these numbers stem from Arizona, they also reflect the national trends showing greater and growing rates of suicide among veterans.

Why are veterans at greater risk?

One reason is that, compared to nonveterans, a greater proportion of veterans are white, male and older – demographic categories with elevated rates of suicide in the general population. For example, in Arizona, about 97% of veteran suicides between 2015 and 2022 were men, compared with 75% in the comparable nonveteran population.

Other explanations relate to veteran-specific factors. Some argue that military training and combat exposure can reduce a person’s fear of pain or death, putting suicidal veterans at greater risk of completing suicide. Military training also familiarizes a person with the use of firearms, a particularly lethal means of suicide. Statistics show that veterans, including female veterans, die by suicide using firearms more so than the general population. This tendency to use firearms as the method of suicide leads to more fatal suicide attempts.

At the Arizona Violent Death Reporting System, we collect data on circumstances that precede and may have contributed to suicide, which can help identify risk factors. While we’ve found that veterans often exhibit fewer such factors overall, certain demographic categories do display risk factors.

For example, a higher proportion of veterans ages 18 to 54 had a diagnosed mental health problem – primarily post-traumatic stress disorder, or PTSD. In addition, more male veterans ages 65 and older had physical health problems that contributed to their suicide compared with similar nonveterans.

This highlights the need to encourage veterans to share their mental or physical health struggles with others, which will prevent veterans from struggling alone. Large-scale initiatives are trying to tackle this issue, but we can also raise awareness and reduce stigma around suicide on a local level.

Shining a light on the problem

In 1999, then-Surgeon General Dr. David Satcher highlighted suicide as a serious public health crisis, paving the way for tackling the monumental issue on a national scale.

Now, 25 years later, the U.S. government continues to emphasize the increasingly dire situation. Most recently, the Biden administration released a 2024 national strategy aimed at establishing strategic directions for improving mental health treatment and reducing suicide.

Historically, health care facilities operated by the Veterans Health Administration have been a central resource for veterans experiencing mental or physical problems. This continues to be true: While the overall population of veterans is decreasing, the number of veterans who seek resources from the organization has increased. Encounters between veterans and the Veterans Health Administration offer opportunities to screen for suicide risk and offer resources for those in need.

Crisis lines are a potentially effective means of prevention. For example, the Veterans Crisis Line has been shown to reduce a caller’s immediate distress and suicidality. Many callers have found the crisis line helpful, with responders providing both effective intervention and compassionate support.

Education and policy provide another means of suicide prevention. As firearms are a particularly lethal means of suicide, a great deal of research funding has gone toward understanding their role in suicide. Studies generally find that reducing access to guns is associated with reduced suicide rates. As a result, both general and veteran-specific suicide prevention efforts highlight the importance of handling guns safely and storing them securely.

If you know a military veteran, keep an eye out for warning signs of mental distress, which may display in a person’s words, feelings or behavior.

For example, they may display intense anxiety, agitation or desperation, or express a sense of hopelessness. Veterans diagnosed with depressive syndrome, PTSD or both may be at greater risk.

For a person who is considering suicide, even the slightest hope can mean the difference between life and death.

If you or someone you know is experiencing signs of crisis, the free and confidential 988 Suicide and Crisis Lifeline is available to call, text or chat.

If you are a veteran and would like to speak with responders trained to understand your unique circumstances, call 988 and then press 1.The Conversation
