Cosa sono gli esercizi di forza?

A strength opzioni di esercizio is any activity that makes your muscles work harder than usual, which increases their strength, size, power, and endurance. This involves using your body weight or working against some sort of resistance, to target specific muscle groups.

Muscle-strengthening activities help maintain your ability to perform everyday tasks and slow down the rate of bone and muscle loss associated with ageing. Health professionals also believe that improving your flexibility can improve your posture, reduce aches and pains, and lower your chance of injury, too. While it's not always possible to prevent a fall, building muscle strength via exercise can help reduce the chance of falls and injury in people over 50. Strength exercises can improve balance too, which can help reduce this likelihood.

According to Dr Leigh Breen, Professor of Translational Muscle Physiology at the University of Birmingham, as we age - from 30 onwards - we slowly lose skeletal muscle mass and strength. This makes it important to perform regular strength training to ensure we slow this process as much as possible. This in turn allows us to continue to perform everyday activities, such as rising from a chair or climbing the stairs, in older age.

"The more muscle and strength we retain, the lower our chance of frailty, disabilità, metabolic diseases - such as diabete di tipo 2 - and early death," says Breen. "Stronger older adults with high levels of muscle mass have much better quality of life.

"As we get older, regular aerobic exercise such as brisk walking can help to support cardiorespiratory fitness and metabolic health, but does not do much for muscle mass and strength."

Alistair Hughes, a personal trainer, explains that improved muscular strength, better support to your skeletal structure, improved co-ordination, and a more defined physique are just a few benefits of strength exercise.

"There is always an option for anyone, ranging from total novices to seasoned athletes," he adds. "Strength training does not just translate to being able to lift bigger weights in the gym - it can massively improve your day-to-day quality of life by helping with your posture and stability.

"Non solo, ma più massa muscolare magra brucia più calorie, il che significa che utilizzerai più energia semplicemente svolgendo le tue normali attività quotidiane."

"A former client of mine came to me feeling weak and exhausted so much of the time, believing she could barely do any exercise at all," says Hughes. "Over the course of four weeks, with a combination of weightlifting and basic yoga, ha più che raddoppiato molti dei suoi pesi iniziali e mi ha detto che si sentiva già di nuovo più come se stessa.

"A strong body can make us feel more confident in our own skin and more capable of completing any physical task laid in front of us."

Many of us put more focus on burning calories, rather than also making sure our bodies stay strong. However, according to Hughes, our ever more sedentary lifestyles mean we aren't getting any of the regular strength training we need to keep a healthy balance.

"It's a good idea to mix up the tipi di esercizio you do and it can rendilo più divertente too, rather than just doing the same thing," he says. "Cardio exercise is fantastic for improving your heart and lung function, maintaining healthy la pressione sanguigna, and burning a high amount of calories in the process. But when we consider the body's strength and aesthetics, cardio training will only take you so far.

"Da un punto di vista della salute, il tuo scheletro richiede il supporto di muscoli forti per mantenerti in movimento in modo fluido e senza dolore mentre avanzi nella vita. Questo tipo di forza può essere ottenuto solo attraverso l'allenamento di resistenza e può essere semplice come eseguire squat o flessioni."

"Atleti come Usain Bolt si sottopongono a un rigoroso allenamento di forza per garantire di poter generare la potenza necessaria per correre così velocemente," spiega Hughes. "Se il tuo obiettivo è più orientato alla corsa su lunghe distanze, allora l'allenamento di forza può aiutarti notevolmente nella prevenzione degli infortuni.

"If you are ever finding you are getting pain in your ankles, shins, thighs, hips, or even your back from running, it is likely that strengthening the corresponding muscle group will help to alleviate that and improve your performance."

For general health, try to do at least 150 minutes of moderate-intensity aerobic activity a week, as well as muscle-strengthening activities on two days a week. But if you're doing vigorous-intensity aerobic activity, you should be able to get all your week's aerobic and muscle-strengthening requirements from 75 minutes of activity. Everyone over 50 should do a combination of both aerobic and specific muscle group exercises, according to the UK Department of Health.

You can also do exercises which only involve your own body weight, such as sit-ups, squats, and lunges. There are many easy-to-follow videos on YouTube. Weight machines at the gym are easy to use once you've been shown how by a fitness instructor and you can tailor them to your abilities.

Hughes says: "If you're ever unsure, there is a wealth of information online or, even better, seek the help of a professional trainer who will be able to help you build up a plan that works for you."
