Intervals Simplified for Enhanced Speed

A recent discussion on Reddit presents a training technique termed the "Easy Interval Method" (EIM). While the creator of this method is trying to market a program, the information shared is both free and intriguing, allowing readers to draw their own conclusions.

Klaus Lok, a notable athlete with 24 Dutch national titles ranging from 1500 meters to 10,000 meters, argues that many runners who fall in the midpack category spend excessive time on low-intensity runs. This may inadvertently train them to maintain a slower pace. Lok proposes a more effective strategy for those aiming to increase their speed.

His methodology, developed partly from the principles of famed coach Mihaly Igloi, advocates for frequent speed workouts each week, but with a twist: these workouts should incorporate "slow speed" intervals in small increments, accompanied by extended recovery periods. This stands in contrast to traditional interval training, which often emphasizes shorter recoveries and more intense repetitions.

Additionally, Lok highlights the importance of incorporating several moderate tempo runs weekly to enhance lactate clearance. This refreshing approach has yielded positive results for me as I transition from a winter regimen focused on slow, marathon-oriented runs. For further insights, visit Reddit Running.

The Lifespan of a $500 Running Shoe

When Tigist Assefa set a world record of 2:11:53 at the Berlin Marathon last September, the Adidas shoes she wore gained significant attention for their speed. However, the hefty price tag of $500 and the claim from Adidas that the shoes would only last for one marathon, plus a brief adjustment period, deterred many everyday runners from considering them.

The shoe, named the Adizero Adios Pro Evo 1, seemed impractical compared to other high-performance shoes priced at around $250. However, a reviewer’s experience with the shoe revealed that it held up much longer than expected. After logging over 300 miles, the reviewer found that although the shoes were no longer suitable for a marathon, they were still effective for shorter distances like 5Ks and 10Ks.

Remarkably, the shoes provided a delightful running experience, described as "pure bliss" despite their light weight and substantial cushioning. Even after extensive use, they continued to deliver a fast, responsive ride, outperforming many other models in the market.

Adidas has since clarified its stance on the shoe's durability, emphasizing that it is "optimized" for one race but not strictly limited to that, suggesting that users can expect decent performance beyond just their first outing. For more information, check out Run Outside.

A New Perspective on Injury Prevention

Numerous attempts have been made to create effective injury-prevention programs for runners, with few yielding successful results. However, a recent study shows promise by adopting a "top-down" approach rather than the conventional "bottom-up" method. This strategy emphasizes strengthening the hips and core over targeting the ankle and foot muscles.

Researchers in Finland divided a group of novice adult runners, mostly female with an average age of 40, into three categories: one group engaged in core and hip strengthening exercises under the guidance of a physiotherapist, the second group focused on foot exercises, and the third group practiced static stretching. Each group followed a structured running regimen for six months.

The findings revealed that the hip and core strengthening group experienced a 39% lower injury rate compared to the static stretching group, and a 52% reduction in significant overuse injuries. Interestingly, the foot exercise group had slightly more injuries than the stretching group.

The researchers posited that the targeted hip and core exercises, such as squats and lunges, bolster the large muscles in the legs and calves that are prone to overuse injuries. While stretching proved beneficial for acute muscle injuries, it had a minimal impact overall, affirming the efficacy of the focused exercise program in preventing lower leg injuries among novice runners.

8 Strategies for Enhanced Running Efficiency

Improving Running Economy (RE) is a goal for many, as better efficiency translates into faster race times across various distances, including 5Ks. This article outlines effective methods to boost RE.

While genetic factors play a role in one's RE, there are steps individuals can take to enhance their efficiency. Research suggests that excessive vertical oscillation negatively affects RE, and landing mechanics can also influence performance. To mitigate these issues, runners should aim for a shorter stride that emphasizes forward movement rather than upward.

Incorporating plyometrics and similar drills can help refine body mechanics, improving overall efficiency. Additionally, many runners find that integrating "strides" into their routine enhances speed efficiency.

One of the strategies highlighted suggests investing in carbon-plated running shoes, which can provide a performance edge, albeit at a higher cost. It's akin to choosing premium fuel for a vehicle—beneficial, but ultimately a personal decision based on financial considerations and individual objectives.

Introducing a Free Sweat Rate Calculator

Hydration specialists have long advocated for personal hydration assessments to determine individual sweat rates, which can vary widely. The traditional method involves weighing oneself before and after a run, but this cumbersome process is often overlooked by runners.

Recently, Australian researchers developed a more user-friendly approach. They conducted a comprehensive study involving runners and cyclists under varying environmental conditions. The data collected was then utilized to create an online calculator designed to assist athletes in managing their hydration needs tailored to outdoor activities.

Available at SweatRateCalculator.com, the tool allows users to adjust parameters such as weight, height, distance, and temperature to calculate their optimal fluid intake per hour. This tool provides valuable insights for runners looking to maintain proper hydration levels during training and races, ensuring they stay within safe limits.

Insights from Veteran Runners: Health Benefits of Multi-Marathoning

What do we learn from the relatively few individuals who have completed over 100 marathons? A recent study involving 830 such runners from around the globe sheds light on their experiences.

These seasoned athletes, averaging 51 years of age, predominantly male, run about 35 miles weekly, with 12% claiming to participate in a marathon every week and 80% running one each month. Most of their mileage comes from races.

Notably, 94% reported that their multi-marathon endeavors positively impacted their mental health. Participants indicated their motivation stemmed from fitness, a sense of achievement, lifestyle, social engagement, travel, and reaching personal milestones.

In terms of footwear preferences, 45% favored cushioned shoes, 27% preferred stability shoes, and 20% opted for minimalist designs. Additionally, 93% utilized GPS watches, and 44% trained with headphones.

Surprisingly, the runners reported few injuries, primarily limited to blisters and chafing, with no significant overuse injury types identified. However, 67% acknowledged using pain relief medications around race times.

The study concludes that older individuals actively participating in multi-marathoning challenge age-related stereotypes, highlighting the sport's potential for fostering lifelong physical activity and the necessity for inclusive practices within running communities. Notably, 94% of participants felt that regular marathon running benefitted their mental health. For more information, visit PLoSONE for the full text.

Examining Our Protein Consumption Trends

Recently, during a run, my training partner mentioned an NPR segment on the need for increased protein intake, especially among older women. This struck me as curious, as I had just read an article questioning the current protein craze.

In that article, Harvard nutrition expert Dariush Mozaffarian humorously noted that protein is the last remaining "good" micronutrient, as carbohydrates and fats have been vilified. While protein is undoubtedly beneficial, the question remains: are we truly lacking in it?

Protein supplements dominate the market, but many experts agree that strength training is essential for building muscle. While protein does play a role in muscle development, evidence suggests that most people, including vegetarians and vegans, are not deficient.

Older adults may experience issues like frailty and sarcopenia due to poor diet and lack of exercise. By improving nutrition and incorporating strength training, these challenges can often be addressed without the need for increased protein intake. A balanced diet and regular exercise are key.
