Scholars and historians offer several theories for the crippling losses suffered by the American Expeditionary Forces on the battlefields of World War I: inexperience, poor leadership, hasty expansion of duties, and others. But until now, most of these studies have focused at the division level or higher. Now, with To the Limit of Endurance, Peter F. Owen offers a tautly worded, historically rigorous, and intensely human survey of the agonizing burden shouldered by the Second Battalion of the Sixth Regiment of U.S. Marines from its formation in Quantico, Virginia, in 1917 until the cessation of hostilities in November of the following year. In places like Belleau Wood and Soissons, these young men, led by dedicated officers, died in staggering numbers--primarily because of the outmoded tactics they had learned. Owen shows how the battalion regrouped after these campaigns, however, and embarked on a period of intense retraining. By the time of the closing weeks of the war, the adjustments they had made allowed them to mold themselves into a coldly efficient military machine. Drawing on a treasure trove of surviving first-hand accounts, Owen expertly combines these individual observations with military records and archival sources to create a mosaic that provides not only a case study of how one organization grappled with transformation but also a tightly focused, ground-level view of the lives--and deaths--of these courageous American military men. The grueling, ultimately triumphant odyssey of the 2nd Battalion, 6th Marines will appeal to military historians, professional soldiers, and interested general readers.

Sudden, extreme deaths have always fascinated us-- and now more than ever as athletes and travelers rise to the challenges of high-risk sports and journeys on the edge. In this spellbinding book, veteran travel and outdoor sports writer Peter Stark reenacts the dramas of what happens inside our bodies, our minds, and our souls when we push ourselves to the absolute limits of human endurance. Combining the adrenaline high of extreme sports with the startling facts of physiological reality, Stark narrates a series of outdoor adventure stories in which thrill can cross the line to mortal peril. Each death or brush with death is at once a suspense story, a cautionary tale, and a medical thriller. Stark describes in unforgettable detail exactly what goes through the mind of a cross-country skier as his body temperature plummets-- apathy at ninety-one degrees, stupor at ninety. He puts us inside the body of a doomed kayaker tumbling helplessly underwater for two minutes, five minutes, ten minutes. He conjures up the physiology of a snowboarder frantically trying not to panic as he consumes the tiny pocket of air trapped around his face under thousands of pounds of snow. These are among the dire situations that Stark transforms into harrowing accounts of how our bodies react to trauma, how reflexes and instinct compel us to fight back, and how, why, and when we let go of our will to live. In an increasingly tamed and homogenized world, risk is not only a means of escape but a path to spirituality. As Peter Stark writes, "You must try to understand death intimately and prepare yourself for death in order to live a full and satisfying life." In this fascinating, informative book, Stark reveals exactly what we’re getting ourselves into when we choose to live-- and die-- at the extremes of endurance.

How to improve exercise performance capacity through adequate nutrition Nutrition is one of the key factors that modulate exercise performance. In this book, a group of expert scientists discuss the ergogenic properties of various nutritional interventions and present research to show that dietary strategies can be applied to extend the limits of human endurance, lower the risk of illness or injury, and speed recovery rates. More specifically, they discuss recent findings on topics such as caffeine and its effect on the brain, carnitine and fat oxidation, ergogenic properties of beta- alanine, dietary protein and muscle reconditioning, nutrition and immune status, and the importance of proper hydration. This publication will provide the reader with many novel insights into the complex interaction between nutrition and exercise, allowing them to define more effective dietary strategies to improve health and performance. Moreover, while focusing on elite athletes, it is interesting to note that some of the discoveries can be applied beyond this niche, for example to improve performance outcomes in the elderly.

A breakthrough program for triathletes -- beginner, intermediate, and advanced -- showing how to balance training intensity to maximize performance -- from a fitness expert and elite coach. Cutting-edge research has proven that triathletes and other endurance athletes experience their greatest performance when they do 80 percent of their training at low intensity and the remaining 20 percent at moderate to high intensity. But the vast majority of recreational triathletes are caught in the so-called "moderate-intensity rut," spending almost half of their time training too hard--harder than the pros. Training harder isn't smarter; it actually results in low-grade chronic fatigue that prevents recreational athletes from getting the best results. In 80/20 Triathlon, Matt Fitzgerald and David Warden lay out the real-world and scientific evidence, offering concrete tips and strategies, along with complete training plans for every distance--Sprint, Olympic, Half-Ironman, and Ironman--to help athletes implement the 80/20 rule of intensity balance. Benefits include reduced fatigue and injury risk, improved fitness, increased motivation, and better race results.

"Surviving the Extremes brings personal experience and scientific knowledge together beautifully, giving us narrative that are powerful, moving, and very real." -Oliver Sacks A true-life scientific thriller no reader will forget, Surviving the Extremes takes us to the farthest reaches of the earth as well as into the uncharted territory within the human body, spirit, and brain. A vice president of the legendary Explorers Club, as well as surgeon, explorer, and masterful storyteller, Dr. Kenneth Kamler has spent years discovering what happens to the human body in extreme environmental conditions. Divided into six sections—jungle, high seas, desert, underwater, high altitude, and outer space—this book uses firsthand testimony and documented accounts to investigate the science of what a body goes through and explains why people survive—and why they sometimes don’t.

With a storyteller's ear for fascinating detail and description, Davis takes readers along as she trains and sets her record, analyzing and trail-testing the theories and methodologies espoused by her star-studded roster of mentors. She distills complex rituals and histories into easy-to-understand tips and action items that will help you take perseverance to the next level. The Pursuit of Endurance empowers readers to unlock phenomenal endurance and leverage newfound grit to achieve personal bests in everything from sports and family to the boardroom.

“Drink as much as you can, even before you feel thirsty." That's been the mantra to athletes and coaches for the past three decades, and bottled water and sports drinks have flourished into billion-dollar industries in the same short time. The problem is that an overhydrated athlete is at a performance disadvantage and at risk of exercise-associated hyponatremia (EAH)--a potentially fatal condition. Dr. Tim Noakes takes you inside the science of athlete hydration for a fascinating look at the human body’s need for water and how it uses the liquids it ingests. He also chronicles the shaky research that reported findings contrary to results in nearly all of Noakes’ extensive and since-confirmed studies. In Waterlogged, Noakes sets the record straight, exposing the myths surrounding dehydration and presenting up-to-date hydration guidelines for endurance sport and prolonged training activities. Enough with oversold sports drinks and obsessing over water consumption before, during, and after every workout, he says. Time for the facts—and the prevention of any more needless fatalities.
