  The Science of Speed -...

  Sprinting and marathon running are two of the most demanding yet contrasting disciplines in athletics. While both require exceptional physical and mental conditioning, the fundamental difference lies in how the body generates and sustains energy. Sprinters rely on explosive power and short bursts of speed, whereas marathoners must master endurance, pacing, and energy conservation over long distances. Understanding the mechanics of speed and endurance is essential for athletes looking to push their limits and optimize their performance. 
  The human body consists of two primary types of muscle fibers: fast-twitch and slow-twitch. Sprinters predominantly utilize fast-twitch fibers, which generate rapid and powerful contractions but fatigue quickly. These fibers enable the quick acceleration and high-speed bursts necessary for short-distance races. Marathon runners, on the other hand, rely more on slow-twitch fibers, which are highly resistant to fatigue and support prolonged, steady-state activity. The composition of these fibers is partly genetic, but with proper training, athletes can develop their muscles to better suit their chosen discipline. 
  Another key difference between sprinting and endurance running is how the body produces energy. Sprinters depend on anaerobic energy systems, which allow them to generate explosive power without requiring oxygen. This system, fueled primarily by stored creatine phosphate and glycogen, is highly efficient for short efforts but leads to rapid exhaustion. In contrast, marathoners primarily use aerobic energy systems, where oxygen plays a crucial role in breaking down carbohydrates and fats to sustain energy for extended periods. This reliance on aerobic metabolism enables runners to maintain a steady pace without depleting energy reserves too quickly.

  A Daring True Story"Truly an epic of adventure and perseverance, this is great inspiration for anyone who thinks of someday tackling the impossible" -- New York Times best-selling author Clive CusslerOn June 10, 2006, four college friends stepped into a 29-foot rowboat as the only American competitors in the first North Atlantic Rowing Race.From the initial idea and chaotic race planning to heaving through cold ocean swells, author and lead rower Jordan Hansen takes us along as the crew heads out from New York Harbor, racing against three other teams; catches theelusive Gulf Stream current; and makes the final dramatic push for the finish line off the coast of England. Hurricane-level winds, giant ocean eddies, passing freighters, and sharks are all elements of the journey, while the tension on board comes to a head on Day 17-with another 55 days to go when the crew realizes their supplies are running out and they must drastically ration their food.The race is set against the backdrop of Jordan's own reflections on both his biological father, who passed away many years earlier, and his stepfather. Combined with the details of how he and his teammates cope within the confines of their tiny boat, and their determination to push their limits, it creates a remarkable coming-of-age story- and an intimate account full of thrilling adventure and compelling emotion."A beautiful sense of place and a compelling portrait of four men locked in an epic struggle with the ocean and, occasionally; with themselves. Gripping."-Roz Savage, first woman to row three oceans and author of ‘Rowing the Atlantic’“Too often in our lives we are told what we cannot do. Hanssen's story deftly accomplishes the opposite. It might not catapult you into a rowboat, but be warned; you may be enticed to alter course."-Jill Fredston, author of Rowing to Latitude

  In the 1980s, Neil Hornsby was one of very few National Football League fans in England. Never one to do anything casually, he began keeping hand-written score sheets of every game using his own tracking system. Soon he'd enlisted some fellow British super fans in his mission to take football information an extra layer deeper. This was the beginning of Pro Football Focus, an analytics company that now supplies data to all 32 NFL teams and every major broadcasting corporation. PFF player grades appear on the screen during Sunday Night Football broadcasts, and PFF's pioneering research and analysis informs discussions at the highest level, from coaching to drafting to game-planning and player evaluation. In Football Is a Numbers Game, Matthew Coller chronicles this improbable start-up tale with unprecedented access, exploring the company's origin as a band of obsessive outsiders, its pivotal acquisition by Cris Collinsworth, and its role in the proliferation of data in the NFL and professional sports. Featuring a cast of memorable characters, this is a portrait of an unlikely business success as well as a behind-the-scenes look at the forces guiding modern NFL teams as they search for a competitive edge.
