Maintaining muscle mass may play a key role in preventing dementia, as aging often leads to pronounced changes such as decreased mobility and loss of strength. Age-related muscle loss is an inevitable event that affects the physical as well as the mental state of humans. New research suggests maintaining skeletal muscle can be key to supporting cognitive functions and may even play a role in preventing dementia.

A study presented at the Radiological Society of North America's annual meeting revealed that elderly patients with lower skeletal muscle mass had about a 60 percent higher risk of dementia. Skeletal muscle forms one-third of our body weight and tends to atrophy with age, and that muscle decline has broad-ranging effects, from increased physical frailty to potential cognitive decline, said Dr. Marilyn Albert, a professor of neurology at Johns Hopkins University.

The researchers measured the size of the temporalis muscle, which is part of the jaw region, as a marker of overall skeletal muscle health. Their findings showed a clear link between reduced muscle mass and an elevated risk of dementia. This connection highlights the urgent need to prioritize muscle maintenance, particularly as age-related conditions like sarcopenia and anabolic resistance pose additional challenges.

Why Muscle Maintenance Becomes Harder With Age

This begins around the age of 30. Then, there is a loss of 3-5% muscle mass every decade. But the decline is faster for those aged 50. Contributing factors include sarcopenia, an umbrella syndrome causing progressive loss of muscle and bone mass. And there is anabolic resistance - reduced skeletal muscle synthesis of protein, making it difficult to build and maintain muscle in the presence of exercise.

Despite these challenges, strength training and endurance exercises remain effective strategies to rebuild muscle and enhance overall health.

5 At-Home Strength Exercises to Build and Maintain Muscle

Fortunately, you don't need to join a gym to maintain muscle strength. Here are five simple yet effective exercises into your routine to help preserve muscle mass and support cognitive health.

1. Calf Raises

• Stand with feet shoulder-width apart. Lift onto your toes, keeping your core tight. Hold for 1-2 seconds, then lower back down. Repetitions: Perform 15 reps for 2-3 sets.
• Benefits: Improves lower leg strength and balance.

2. Plank

• Lay face-down and position forearms on the ground. Stretch legs back and curl toes under.
• Press your body against the ground, with it straight and core tight.
• Repetitions: 15-20 seconds holds for 2-3 sets.
• Benefits: Strengthens the core, shoulders, and back muscles.

3. Squat Into Chair

• Stand a half step away from a chair.
• Lower into a squat until you nearly touch the chair, extending arms forward.
• Return to standing, bringing arms back in.
• Repetitions: Repeat for 2-3 sets of 10-15 reps.
• Benefits: Strengthens the muscles in the legs as well as helps to better your posture.

4. Elevated Pushups

• Position hands on a wall with feet shoulder-width apart.
• Perform a push-up and lower toward the wall, then return to beginning.
• Repetitions: Do 2-3 sets of 10-15 reps.
• Benefits: Stretches chest, arms, and shoulders with minimal strain.

5. Wall Angels

• Stand with your back against a wall, pressing hips, shoulders, and elbows into the wall.
• Push your arms up into a "Y" shape and then back down.
• Repetitions: Do 10-15 reps for 2-3 sets.
• Benefits: Helps to improve shoulder mobility and posture.

Additional Tips for Muscle Maintenance

Safety and effectiveness are guaranteed by following the given tips:

1. Always warmup at the start and cool down at the end to avoid being injured.

2. Maintain proper posture and control during every movement.

3. Progressively increase weights or resistance bands as strength is enhanced.

4. Complete each movement slowly in order to achieve control and to avoid straining.

5. Give your muscles time to recover and rebuild between sessions.

For many working professionals, going to the gym often feels like a luxury. Their days begin early and end late—rushing for buses and metros, juggling deadlines, presentations, meetings, and endless reports.

So when they are diagnosed with conditions like diabetes or high blood pressure, the most practical and affordable option left is walking. Another common step is cutting down on sugar in tea and coffee. While these are good starting points, these may not be enough.

Calling them "most frustrating", Dr. Sudhir Kumar, Neurologist at Apollo Hospital, Hyderabad noted that such "patients are losing a battle they think they are winning".

"Every day, I see patients with obesity, Type 2 Diabetes, or hypertension who tell me: 'I walk every morning, Doctor'. 'I do all the household work.' 'I have stopped adding sugar to my tea'," said Dr Kumar, in a post on social media platform X.

He also cited these as "dangerous health misconceptions", wherein the patients feel they have done their part, but "their blood work and body composition tell a different story".

Popularly known as the Hyderabad doctor on X, the noted neurologist shared some evidence-based reality of why "walking and quitting sugar" may not be enough.

Several studies have pointed out that walking or undertaking household chores is better than a sedentary behavior. However, neither can be a "substitute for strength training", Dr. Kumar said.

Although walking can burn a few calories, "strength training builds the 'engine' that burns glucose even while you sleep".

"If you are not lifting weights or doing resistance training at least twice a week, your insulin resistance will likely persist, regardless of your step count", he said.

Speaking to HealthandMe, Dr. Manisha Arora, Director - Internal Medicine at the CK Birla Hospital, Delhi, explained that cutting sugar and walking are good first steps, but they do not solve the problem of diabetes and high blood pressure.

"Insulin resistance, inflammation, and loss of muscle all contribute to these diseases. Light walking may help, but the intensity and duration of exercise are also important," he added.

What Is Strength Training?

Strength training exercises force muscles to contract against an external force, such as body weight, dumbbells, or bands. Common examples include

• squats,
• lunges,
• step-ups,
• push-ups,
• planks.

Strength training helps

• Decrease insulin resistance
• Lower blood pressure
• Improve cognitive function
• Reduce systemic inflammation
• Protect against neurodegenerative diseases like Alzheimer’s.

Focus On Protein Leverage

Dr. Kumar further mentioned the diet trap that most people fall into, that is., cutting out sweets and sugar, while loading up the plate with carbohydrate-rich foods such as rice, roti, and poha — 80 percent — and zero protein content.

"Refined carbohydrates (even without added sugar) spike insulin similarly to sugar," he said, calling "no sugar as the bare minimum".

The doctor noted that "a protein-deficient diet can lead to muscle loss and increase hunger".

To lower blood sugar levels, the experts urged to cut down on other foods, such as

• refined carbohydrates,
• processed foods,
• low-fiber foods.

"Focus on protein leverage. Prioritize 1.2g to 1.5g of protein per kg of body weight. When you hit your protein goals, your craving for carbs naturally drops," Dr. Kumar said.

To see the real change in blood sugar and BP levels, he advised people to "add two days of resistance training (bodyweight, bands, or weights)", instead of "just walking",.

The neurologist also recommended "starting the meal with protein paneer, eggs, sprouts, lean meat, and to eat carbs last, and in smaller portions".

In addition, a diet high in protein and fiber from whole grains, fruits, and nuts can also help control blood sugar levels.

"The most successful approach to controlling blood sugar results from combining aerobic exercise with strength training, along with balanced nutrition," said Dr Arora.

We often assume that having a “normal weight” automatically means being healthy. While body weight is an important parameter, it represents only a small part of overall health. True health is far more complex than what a number on the weighing scale can convey.

Understanding The Limitations Of BMI

Body Mass Index (BMI) is widely used to classify individuals based on their weight relative to height. However, it does not differentiate between fat and muscle. As a result, someone may fall within the normal BMI range yet still have high body fat and low muscle mass, a condition known as “normal weight obesity.” Such individuals may appear healthy but remain at risk for metabolic disorders.

Why Is Body Composition Important?

Body composition analysis offers deeper insight by evaluating fat, muscle mass, and their distribution in the body. A combination of low muscle mass and excess body fat, especially around internal organs, can increase disease risk, even when overall weight appears normal.

The role of fat distribution:

All body fat is not the same. Where fat is stored matters significantly. The waist-to-height ratio is now considered a more reliable indicator than BMI, as it reflects fat distribution. A ratio above 0.5 is associated with a higher risk of conditions such as type 2 diabetes, cardiovascular diseases, and even increased mortality.

Looking beyond numbers:

Health cannot be defined by numbers alone. Factors like physical activity, nutrition, stress levels, and sleep quality play an equally critical role. Even individuals with a normal weight can experience poor metabolic health due to inadequate sleep or chronic stress.

The bigger perspective:

Good health is not just about appearance or weight, it is the result of multiple factors working together. It reflects a balance between internal processes and external lifestyle choices.

In essence, being of normal weight does not necessarily mean being healthy. To truly stay well, it is important to look beyond weight and consider the broader picture of health.

Los Angeles Lakers star Luka Doncic is set to fly to Europe to seek specialized treatment on his Grade 2 left hamstring strain, according to a media report.

Doncic suffered the injury during Thursday's 134-96 loss to the Oklahoma City Thunder.

Though Grade 2 hamstring strains typically involve a monthlong recovery process, Doncic is motivated to return to theLakers' lineup during the playoffs -- which is a shared goal for Austin Reaves, who is out because of a Grade 2 left oblique muscle injury, the basketball player’s agent Bill Duffy told ESPN.

What Is A Hamstring Strain

Hamstring muscles power a player’s acceleration. Sudden bursts of speed without adequate flexibility or strength can cause a strain. It can be a pull, a partial tear, or a complete tear.

Symptoms include:

• Sudden Sharp Pain
• Physical Sensations
• Physical Changes
• Reduced Mobility

Prevention includes stretching, foam rolling, and strengthening exercises like deadlifts, leg curls, and bridges.

Hamstring strains are graded according to their severity. A grade 1 strain is mild and usually heals readily; a grade 3 strain is a complete tear of the muscle that may take months to heal.

What Are The Common Injuries In Basketball?

Basketball players are more likely to get hurt during matches than during training, with risks coming from tackling, sprinting, twisting, jumping, or even repeating the same movements until fatigue sets in. Collisions, poor conditioning, or re-injuring a previously weakened area can also contribute.

Sprained Ankle

Quick changes of direction and uneven surfaces make ankle sprains one of the most common basketball injuries. This happens when the ankle rolls inward or outward, overstretching the ligaments.

Protect, Optimal loading, Ice, Compression, Elevation, and avoid HARM factors: Heat, Alcohol, Running, Massage, in the first three days.

Groin Strain

Twisting, kicking, or rapid directional changes can strain the inner thigh muscles, also known as adductors.

Prevention is through regular stretching and strengthening exercises such as side lunges and adductor side bridges.

ACL Injury

The anterior cruciate ligament is critical for knee stability. Injuries often occur when the lower leg stays planted while the upper leg twists, during tackles, or awkward landings.

Mild sprains may heal with physiotherapy, but severe tears often require surgery. Persistent swelling or pain should be checked by a professional.

Preventing Basketball Injuries

• Strengthen lower limbs with exercises like squats, lunges, and calf raises.
• Warm up with dynamic stretches and sport-specific drills.
• Cool down after matches to aid recovery.
• Wear proper gear, including fitted boots and shin guards.
• Stay hydrated, eat well, and rest between games.
