Nations on high alert as Covid variant spreads

Health officials said on Monday that Russia has confirmed the country’s first two cases of the Omicron coronavirus variant among travelers returning from South Africa.

Due to the new variant, Russia restricts the entry of all foreigners traveling from southern African countries and requires all Russian nationals returning from South Africa or neighboring countries to quarantine for 14 days as of Thursday.

The Ministry of Health of Namibia said on Monday that Namibia had detected Omicron variants in 18 of the 19 samples sequenced between November 11 and 26.

Although relatively few samples have been sequenced in this southern African country, the results of the study show that the mutations that were first marked by neighboring South Africa and Botswana and marked as “notable” by the World Health Organization at the end of last month are also very common in Namibia.

In addition, Pakistan banned travel from 15 countries including the Netherlands and South Africa on Monday, except in certain circumstances, and tightened travel restrictions on 13 other countries following the threat of new variants. Croatia confirmed the first two cases on Monday, the State Institute of Health said, Omicron.

“We are not sure about the source of the infection because neither of these two people traveled abroad. We believe they were infected at a business meeting where both parties attended,” Bernard Cage, an epidemiologist at the State Institute of Health Kaic) said.

Japan confirmed its third new case of the omicron variant on Monday, as Prime Minister Fumio Kishida vowed to take strict measures based on the worst-case scenario in which the infection may return.

Chief Cabinet Secretary Hirowa Matsuno told reporters that the third confirmed case was a man in his 30s who tested positive after arriving at Tokyo’s Haneda Airport from Italy on December 1 and has since been quarantined. The outbreak of the Omicron variant did not show the resulting surge in hospitalizations. Anthony Fauci, the chief medical adviser to US President Joe Biden, said on Sunday: “So far, it does not seem to be of great severity, but he warned that it is too early to make a conclusion.”

At the same time, Italy on Monday tightened restrictions on people who have not yet been vaccinated against Covid-19, limiting their access to a range of places and services.

According to the new regulations, only people who have been vaccinated or who have recently recovered from Covid-19 can enter indoor seating in bars and restaurants, visit museums, go to cinemas and clubs, and participate in sporting events.

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.
