Extreme exercise and the potential cardiovascular risks – Times of India

Exercise is one of the most effective ways to improve cardiovascular health, but it doesn’t mean you need to run marathons to see the benefits. Moderate exercise spread over a lifetime is linked to good cardiovascular outcomes. However, it is essential to understand the right balance of volume and intensity for maximum benefit. According to the American Heart Association (AHA) guidelines, 150 minutes of moderate-intensity exercise per week has been proven to significantly benefit heart health.
Exercise not only strengthens the heart but also helps in reducing triglyceride levels, increasing HDL (“good” cholesterol), lowering inflammatory markers, reducing body weight, and improving glucose metabolism and insulin sensitivity. It also helps lower blood pressure, highlighting the many positive effects of physical activity.
Safe limits for physical activity
Determining the precise “cutoff” limit for physical activity is still being studied. While there is no definitive answer yet, it is clear that the benefits of regular exercise far outweigh the risks of a sedentary lifestyle. The key takeaway is that inactivity is riskier than exercising, regardless of the level of intensity.
Essential guide to safe and effective exercise for heart health
When starting an exercise program, it’s important to begin with a light routine and gradually increase intensity based on your body’s response. A baseline heart evaluation is recommended before engaging in any exercise regimen, especially for those with pre-existing heart conditions. It’s also vital to include proper warm-up and cool-down phases to allow the body to adjust to the activity and reduce the risk of injury or cardiac events.
For most people, moderate-intensity exercise for 5 to 7 days a week provides significant cardiovascular benefits. However, individuals with heart issues should consult their doctor before beginning any exercise program. The message here is simple: regular exercise is more beneficial than no exercise at all.
While there are concerns about extreme levels of physical activity, such as in professional athletes or endurance sports participants, these risks are generally associated with those who are unaccustomed to such intense training or have underlying heart conditions. Data has shown that long-term, excessive exercise can lead to structural and functional changes in the heart, including enlargement of the cardiac chambers and the release of certain biomarkers, which could indicate heart stress.
Though these biomarkers typically return to normal within a week, repetitive strain on the heart over months and years can cause scarring (myocardial fibrosis) and increase the risk of arrhythmias, such as atrial fibrillation, which raises the likelihood of stroke.
Bottom line
While regular moderate exercise greatly enhances cardiovascular health, it’s crucial to avoid extremes. Finding balance and consulting healthcare professionals ensures long-term benefits while safeguarding heart health against risks.

Exercise ‘snacks’ can keep your fitness on track when time is tight – try these 3 today

December is great for many things – socialising, scoffing, falling out with relatives – but sticking to a training schedule is not one of them.

Heading out the door on Christmas morning for a two-hour long run is likely to put anyone on the naughty list, while it takes a dedicated runner indeed to spend part of the festive period running loops of the track.

What the mere mortal needs is exercise “snacks”. These can be enjoyed/endured alongside the carb-based variety and snuck in to even the busiest Christmas schedule.

A review in Sports Medicine and Health Research confirmed that regular, short bursts of physical activity throughout the day improved cardiovascular respiratory fitness, increased fat oxidation and polished off blood sugar levels after eating.

Vigorous intermittent exercises, such as sprints, were good for building muscle strength. Meanwhile, 10-minute resistance training sessions were found to be particularly beneficial to older people. The researchers concluded that exercise snacks could be a viable alternative to longer, less frequent sessions.

Study shows the antioxidants in this tea improve exercise recovery

I love many different herbal teas just as much as I enjoy a good old-fashioned British cup of PG tips, Earl Grey, or Glengettie — a Welsh favorite from the rolling valleys where I was born. In an interesting study, researchers explored whether drinking green or matcha tea can improve sports performance and exercise recovery, and the results might have you reaching for a vibrant green drink. If you want to get straight to the results, the short answer is that drinking green and matcha tea can support hydration, body fat control, and exercise recovery. Still, it definitely won’t be a game-changer when it comes to your performance in the gym, on the court, or on the field.

Hydrating with tea

In a study published in Nutrition and Food Technology, researchers reviewed existing studies of athletes and active adults that focused solely on drinking tea — no pills or extracts. They revealed that green or matcha tea can help hydrate the body when consumed in normal amounts. Tea counts toward your daily water intake.

Antioxidants and recovery

The research highlighted how the widely-studied antioxidants in green and matcha tea can improve exercise recovery and help protect your cells from the stress associated with intense exercise. That said, the research shows that drinking tea won’t lead to faster or better strength gains, so it’s no silver bullet for helping you achieve your fitness goals. However, they also concluded that low-caffeine green tea could even improve sleep quality, which I would argue could potentially help you power through that workout if you’re getting better sleep the night before.

Linked to lower body fat

Interestingly, the study authors also concluded that drinking around two or three cups of green or matcha tea per day was associated with slightly lower body fat and improved body composition and fat burning. While the effects weren’t overly significant, they were noted in the research. Cup of tea, anyone?

Taylor Swift’s fitness strategy that made 632 days long Eras Tour possible: Her exercise routine to stay energized

Taylor Swift’s fitness strategy that made 632 days long Eras Tour possible: Her exercise routine to stay energized
Taylor Swift’s Eras Tour was a feat few artists could imagine. Spanning 632 days from March 2023 to December 2024, the tour included 149 shows across five continents and became the highest-grossing tour in history. Behind the glittering performances, Swift relied on an intense and meticulously planned exercise routine to sustain the stamina required for her marathon three-and-a-half-hour concerts.

Preparing for a Physical Marathon

Before the tour began, Swift recognized the physical challenge she was about to face. “I never would’ve believed you if you told me we were doing a three-and-a-half-hour show. Saying it is one thing, doing it is another,” she admitted in the Disney+ docuseries The End of an Era. For comparison, her longest previous show had lasted just two hours and 15 minutes.

To meet these demands, Swift began training six months ahead of her first rehearsal. Her daily treadmill sessions mirrored the tempo of the songs she would perform live, with faster tracks prompting running and slower songs calling for brisk walks or light jogging. “You just don’t want them to see you panting,” she explained to TIME.

Strength and Conditioning Regimen

While cardio built endurance, strength training ensured she could perform high-energy choreography without fatigue. Under the guidance of longtime trainer Kirk Myers, Swift tackled exercises such as battle ropes, medicine ball throws, assisted pull-ups, sledgehammer workouts, leg raises, and Russian twists. Myers described her as “the most resilient person I have ever met,” highlighting her ability to persevere through challenging workouts.

Swift’s humor surfaced even during difficult exercises. “In no way do I ever apply this … at any point in the show, I just want to flag that as I do every time I have to do pull-ups. Strong dislike. Two thumbs down,” she said, referring to resistance band-assisted pull-ups. She jokingly attributed her increasing strength to “all the pent-up rage and resentment” she felt toward the moves.

Dance Training and On-Stage Precision

Beyond the gym, Swift committed three months to dance rehearsals with choreographer Mandy Moore to ensure every move was second nature. “I wanted to be so over-rehearsed that I could be silly with the fans, and not lose my train of thought,” she shared with TIME. The precision extended to rapid costume changes, often completed in under 1 minute and 15 seconds, with the fastest taking just 39 seconds.

Swift ran an estimated eight miles per show while performing over 40 songs that spanned her musical eras. High-cardio sections, including the 1989 and Reputation sets, were particularly demanding. Yet she described the physical challenge as secondary to the personal purpose the tour provided, especially during a period marked by two breakups.
