What we know about Russia’s new laser weapons, Peresvet and Zadira

Russia claimed on Friday that it used powerful laser weapons in its brutal war on Ukraine; the ‘next generation’ weapons were used to burn down drones launched by Ukrainian forces, according to Moscow. The weapons are thought to include a mobile laser system first announced by Vladimir Putin in 2018 and capable of blinding orbiting satellites as well as destroying drones, according to Russia.

The use of lasers by Russia has heightened fears of advanced weaponry, such as the Kinzhal hypersonic missile or even nuclear or chemical weapons. President of Ukraine Volodymyr Zelensky appears unconcerned (for the time being) and has mocked Russia, comparing the laser weapons to Nazi Germany’s “wonder weapons” promised to avoid defeat in World War II.

In 2018, Putin debuted a slew of new weapons, including an intercontinental ballistic missile, underwater nuclear drones, a supersonic weapon, and a laser system.

It is unclear how many laser weapons systems Russia controls; the names of at least two of them, Peresvet and Zadira, have been circulated.

In 2018, Putin unveiled Peresvet, a weapon named after a mediaeval warrior monk named Alexander Peresvet. The weapon’s capabilities and capabilities are unknown. It can be used against drones, or unmanned aerial vehicles, according to military experts, but bad weather can thwart it.

On Wednesday, Russia’s deputy prime minister in charge of military development, Yury Borisov, claimed that Peresvet had been deployed and that it could blind satellites up to 1,500 kilometres above the Earth.

Borisov also warned of even more powerful laser weapons systems, such as those capable of destroying drones and other equipment, and claimed that they had been deployed in Ukraine. “…the first prototypes are already in use there,” he said, adding that the weapon’s name is Zadira.

“If Peresvet blinds, then the new generation of laser weapons results in the target’s physical destruction – thermal destruction, they burn up,” he told Russian state television. Borisov claimed that a military test (which he did not independently verify) resulted in a drone five kilometres away being destroyed in five seconds.

Zadira, like Peresvet, is a character about whom little is known. According to Reuters, Russian media reported in 2017 that the state nuclear corporation Rosatom was assisting in the development of a laser weapon as part of a programme to develop weapons based on new physical principles.

A retired Australian army major general told The Washington Post that weapons like Zadira could take down reconnaissance drones and Ukrainian artillery, as well as blind Ukrainian soldiers. However, he added, the latter tactic is prohibited by international convention.

Train smarter, not harder: How taking occasional breaks from gym can revolutionise your fitness routine

Train smarter, not harder: How taking occasional breaks from gym can revolutionise your fitness routine

Taking regular breaks from intense training, like deload weeks, helps your body recover, preventing fatigue and injury, and ultimately boosts fitness gains.

When it comes to getting fit, the idea of spending hours at the gym might come to mind, but many fitness experts argue that taking a “deload week” every six to eight weeks is actually key to improving your fitness gains. A deload week involves reducing the intensity of workouts to allow the body to recover from the fatigue and muscle damage caused by intense training.

While high-intensity training helps build strength and fitness, it can also lead to muscle strain, and without adequate recovery, these gains can’t fully materialise. Deload weeks give the body much-needed rest to repair and rebuild, ensuring continued progress. (Also read: Bhagyashree swears by this super easy exercise for instant leg pain relief and better mobility.

Why recovery is key for muscle growth

According to an article by The Conversation, intense exercise can cause tiny tears in muscle fibres, leading to inflammation that requires rest or low-intensity exercise to heal. This inflammation is essential for muscle growth and fitness improvements. However, without proper recovery, muscles remain in a state of slight damage, preventing inflammation from resolving. This chronic state of inflammation can hinder muscle function, reducing oxygen efficiency and impairing performance. Giving muscles time to recover through rest ensures they repair properly and are primed for continued progress, setting us up for greater success in our fitness journey.

Many gymgoers fear taking time off and are worried it will lead to a loss of gains. However, research shows that muscle genes have a “memory imprint,” which keeps them in a semi-prepared state. This allows muscles to respond more quickly and effectively to future training, promoting growth after a rest period. Even after extended periods of reduced intensity, up to seven weeks, muscular fitness can be restored to prime condition—and in some cases, surpass previous levels. Interestingly, recovery can occur twice as fast as it took to reach peak fitness initially, even if some strength is lost.

Taking time off from intense training is crucial to prevent muscle soreness and avoid overtraining syndrome. Overtraining occurs when the body doesn’t get enough rest, leading to prolonged fatigue, decreased performance, and mood disturbances. Symptoms develop gradually, making overtraining difficult to recognize until it’s severe. Rest is essential to avoid these issues and ensure long-term progress in training.

Role of overtraining syndrome and deload weeks

Overtraining syndrome is challenging to quantify due to its vague symptoms. Studies suggest it may affect as few as 10% of elite athletes, though rates could climb to 60% among highly competitive individuals. Recovery is essential for both fitness and overall health. When engaging in heavy gym routines, it’s vital to incorporate sufficient recovery time into your workout plan. Unlike rest days, which involve little to no exercise once or twice a week, deload weeks feature lighter training at reduced intensity—typically about 50% fewer workouts or a 20% drop in workout intensity.

Both rest days and deload weeks are essential for recovery and crucial to improving fitness. It’s not about choosing one over the other—they complement each other. For instance, intense training for marathons, Ironman, or CrossFit competitions requires weekly rest days alongside scheduled deload weeks. However, for recreational gym-goers exercising 1–3 times weekly at a moderate intensity, the recovery from this routine is often sufficient without the need for additional deload weeks.

Fitness influencers recommend incorporating deload weeks into training schedules every 4–8 weeks, aligning closely with the expert advice of 4–6 weeks. However, it’s crucial to listen to your body and schedule deload weeks as needed. If your performance plateaus or worsens, it may signal time for a deload. Training plans should be flexible enough to allow rest when required. Deload weeks not only enhance performance but also support overall health.
