Sometimes the crack of the bat or the roar of the crowd fails to capture the meaning of sports as athletes themselves understand it. Books about sports have ignored this dimension of the subject, particularly the athletes’ own autobiographical accounts. In Sporting Lives, the first book to examine the two popular realms of sports and autobiography, James Pipkin looks at recurring patterns found in athletes’ accounts of their lives and sporting experiences, examining language, metaphor, rhetorical strategies, and other elements to analyze sports from the inside out.
Sporting Lives takes a fresh look at memoirs from baseball, football, basketball, golf, and other sports to explore how American athletes see themselves: not only how those images mesh with popular perceptions of them as heroes or celebrities but also how their accounts differ from those of sports journalists and other outsiders. Drawing on the life stories of such well-known figures as Wilt Chamberlain, Babe Ruth, and Martina Navratilova—both as-told-to and self-authored works—Pipkin follows players from the “echoing green” of eternal youth to the sometimes cultlike and isolated status of fame, interpreting recurring patterns both in the living of their lives and in the telling of them. He even considers Dennis Rodman’s four autobiographies to show how the contradictions of his self-portrayals reflect the Janus-faced quality of sports in the era of celebrity culture.
As Pipkin shows, the life of the athlete involves more than mere athleticism; it is also a world of nostalgia and sentiment, missed opportunities and lost youth. He sheds light on athletes’ common obsession with youth and body image—including gender and racial considerations—and explores their descriptions of being “in a zone,” that transcendent state when everything seems to click. And he considers the time that all athletes dread, when their bodies begin to betray them . . . and the cheering stops.
While the lives of athletes may often suggest the magic of Peter Pan, Pipkin’s engaging study reveals that they are in many ways more like the Lost Boys. Sporting Lives shows that the meaning of sports is intertwined with the telling. It is both an eminently readable book for fans and a critically sophisticated analysis that will engage scholars of literature, sports or media studies, and American popular culture.

The typical female sports fan remains very different from her male counterparts. In their insightful and engaging book, Sportista, Andrei S. Markovits and Emily Albertson examine the significant ways many women have become fully conversant with sports—acquiring a knowledge of and passion for them as a way of forging identities that until recently were quite alien to women.
Sportista chronicles the relationship that women have developed with sports in the wake of the second wave of feminism of the late 1960s and early 1970s. The changes women athletes have achieved have been nothing short of revolutionary. But, as Markovits and Albertson argue, women’s identities as sports fans, though also changed in recent decades, remain notably different from that of men. Sportista highlights the impediments to these changes that women have faced and the reality that, even as bona fide fans, they “speak” sports differently from and remain largely unaccepted by men.

These groundbreaking essays demonstrate how Africans past and present have utilized sports to forge complex identities and shape Africa’s dynamic place in the world.
Since the late nineteenth century, modern sports in Africa have both reflected and shaped cultural, social, political, economic, generational, and gender relations on the continent. Although colonial powers originally introduced European sports as a means of “civilizing” indigenous populations and upholding then current notions of racial hierarchies and “muscular Christianity,” Africans quickly appropriated these sporting practices to fulfill their own varied interests. This collection encompasses a wide range of topics, including women footballers in Nigeria, Kenya’s world-class long-distance runners, pitches and stadiums in communities large and small, fandom and pay-to-watch kiosks, the sporting diaspora, sports pedagogy, sports as resistance and as a means to forge identity, sports heritage, the impact of politics on sports, and sporting biography.

Chicago teams have won the World Series, Super Bowl, multiple Stanley Cups, and a string of National Basketball Association titles. But amateur sports also play a large role in the city's athletic traditions, especially in schools and youth leagues that allow people from across the city to add to Chicago sports history.
In Sports and Chicago, an all-star roster of experts focuses on multiple aspects of Chicago sports, including long looks at amateur boxing, the impact of gender and ethnicity in sports, the politics of horse racing and stadium building, the lasting scandal of the Black Sox, and the once-perpetual heartbreak of the Cubs. Illustrated with forty photographs, the collection encourages historians and sports fans alike to appreciate the long-standing importance of sports in the Windy City.

If a religion cannot attract and instruct young people, it will struggle to survive, which is why recreational programs were second only to theological questions in the development of twentieth-century Mormonism. In this book, Richard Ian Kimball explores how Mormon leaders used recreational programs to ameliorate the problems of urbanization and industrialization and to inculcate morals and values in LDS youth. As well as promoting sports as a means of physical and spiritual excellence, Progressive Era Mormons established a variety of institutions such as the Deseret Gymnasium and camps for girls and boys, all designed to compete with more "worldly" attractions and to socialize adolescents into the faith.
Kimball employs a wealth of source material including periodicals, diaries, journals, personal papers, and institutional records to illuminate this hitherto underexplored aspect of the LDS church. In addition to uncovering the historical roots of many Mormon institutions still visible today, Sports in Zion is a detailed look at the broader functions of recreation in society.

The stories behind and legacies of important sports photos from the last 130 years.
Ever since photography and professional sports originated in the nineteenth century, photographers have shaped how we perceive sports. Sports through the Lens collects essays by twenty-five historians that consider what it means to capture and revisit a moment of cultural significance in sports, looking at each photo’s creation, its contexts, and how its meaning has shifted over time. Some essays provide fresh perspectives on such iconic images as Muhammad Ali standing over Sonny Liston at their 1965 rematch and Michael Jordan soaring at the 1988 NBA All-Star Game slam dunk competition; others introduce readers to the lesser-known stories of the first woman to officially run the Boston Marathon or the inaugural World Indigenous Games. The authors examine the photos' legacies alongside the artistry of both the athletes and the photographers. Reflecting on images of athletes from around the world engaged in sports from baseball to horse-racing to hockey, Sports through the Lens provides a wide-ranging meditation on the visual, historical, and cultural meaning of sports photographs.

From ancient Egyptian archery and medieval Japanese football to contemporary American baseball, every sport has been shaped by—and in turn has helped shape—the culture of which it is part. Yet as Allen Guttmann shows in this far-ranging study, for all their differences sports have followed a similar historical trajectory from traditional to modern forms.
In Sports: The First Five Millennia, Guttmann traces this evolution across continents, cultures, and historical epochs to construct a single comprehensive narrative of the world's sports.

The legendary University of Chicago football program had an unusual beginning, a dazzling middle, and an inglorious conclusion. Its architect: Amos Alonzo Stagg, the most creative and entrepreneurial college coach of his time. A former all-American gridiron star at Yale, Stagg joined an elite academic institution that boasted intellectual notables like John Dewey, Thorstein Veblen, and Albert Michelson. Within fifteen years, the fame of Stagg's football program had eclipsed even Michelson's renown as the first American citizen to win a Nobel Prize.
Robin Lester follows the commercial trail blazed by Stagg and University President William Rainey Harper and the subsequent transformation of college football into a mass entertainment industry that changed campuses and captured the national imagination. Fascinating and detailed, Stagg's Universityreveals how the University of Chicago's football industry prefigured today's billion-dollar sport juggernaut and details the life and leadership of one of its foundational personages.
Gloria Hochman
Temple University Press, 2020
The late Philadelphia Daily News sportswriter Stan Hochman was known for his many zingers, such as “Harry Litwack, the stoic Temple coach, stalks the sidelines like a blind man at a nudist colony.” As a reporter, he was more interested in how athletes felt, what their values were, how they lived their lives, or what made them tick than he was about how many runs they scored or punches they landed.
In Stan Hochman Unfiltered, his wife Gloria collects nearly 100 of his best columns from the Daily News about baseball, horse racing, boxing, football, hockey, and basketball (both college and pro), as well as food, films, and even Liz Taylor. Each section is introduced by a friend or colleague, including Garry Maddox, Bernie Parent, Larry Merchant, and Ray Didinger, among others.
Hochman penned a candid, cantankerous column about whether Pete Rose belongs in the Baseball Hall of Fame; wrote a graphic account of the Muhammad Ali and Joe Frazier fight of the century; and skewered Norman “Bottom Line” Braman, the one-time owner of the Eagles. He also wrote human-interest stories, including features about the importance of kids with special needs playing sports.
In addition to being a beloved writer, Hochman was also known for his stint on WIP’s radio as the Grand Imperial Poobah, where he would settle callers’ most pressing debates. Hochman long earned the respect and admiration of his subjects, peers, and readers throughout his career, and Stan Hochman Unfiltered is a testament to his enduring legacy.

The essayists include scholars in anthropology, psychology, film studies, communication studies, and sociology, one of whom used to wrestle professionally. Classic studies of wrestling by Roland Barthes, Carlos Monsiváis, Sharon Mazer, and Henry Jenkins appear alongside original essays. Whether exploring how pro wrestling inflects race, masculinity, and ideas of reality and authenticity; how female fans express their enthusiasm for male wrestlers; or how lucha libre provides insights into Mexican social and political life, Steel Chair to the Head gives due respect to pro wrestling by treating it with the same thorough attention usually reserved for more conventional forms of cultural expression.

Jennifer Ring
University of Illinois Press, 2013
Jennifer Ring questions the forces that try to keep girls who want to play baseball away from the game. Focusing on a history that, unfortunately, repeats itself, Ring describes the circumstances that twice stole baseball from American girls: once in the late nineteenth and early twentieth century, and again in the late twentieth century, after it was no longer legal to exclude girls who wanted to play. In the early twentieth century, Albert Goodwill Spalding--sporting goods magnate, baseball player, and promoter--declared baseball off limits for women and envisioned global baseball on a colonialist scale, using the American sport to teach men from non-white races and non-European cultures to become civilized and rational. And by the late twentieth century, baseball had become serious business for boys and men at all levels, with female players perceived as obstacles or detriments to rising male players' chances of success.
Stolen Bases also looks at the backgrounds of American softball, which was originally invented by men who wanted to keep playing baseball indoors during cold winter months but has become the consolation sport for most female players. Throughout her analysis, Ring searches for ways to rescue baseball from its arrogance and sense of exclusionary entitlement.

From Spears and Blowpipe Darts to the Ultimate Human-Powered Projectile
The arrow, essentially a specialized spear, is among the most ancient human inventions and can be found in cultures throughout the world. The need to launch a projectile farther and with greater accuracy than is possible with the human arm gave rise to a variety of solutions. Spearthrowers which extend the length of the user’s arm and therefore transfer greater power to the projectile were developed far back in prehistory, and both the American Indian atlatl and the Australian woomera are examples of this technology. Blowpipes, too, are recorded in various cultures and represent another ancient technology. It was soon discovered that a stringed bow could launch a small spearlike projectile we now know as the arrow, and this combination became the dominant method for shooting projectiles for tens of thousands of years. A wonderfully simple device, the arrow and bow revolutionized both hunting and warfare, not only because of the speed, force, and accuracy that could be achieved, but by the fact that the arrow makes almost no sound as it flies toward its target, providing an essential element of surprise.
In Straight and True: A Select History of the Arrow, Hugh D. H. Soar describes the transition from hand-thrown spear to bow-launched arrow and then follows the arrow’s developments in cultures around the world and across time. The book describes arrows found in Neolithic sites; those used by North and South American Indians—including a detailed discussion of poison-tipped arrows; arrows used in China, Japan, and Mongolia; and finally the arrow in Europe, where it was successfully paired with the longbow during the Middle Ages. After discussing the development of the arrow for sport and recreation, the author completes his survey with the changes in technology introduced during the twentieth century though the use of the alloy of aluminum with other lightweight metals as well as synthetic materials to construct parts of the arrow. Relying on his considerable knowledge accumulated through decades of research, the author provides the reader with an appreciation for a humble device that, coupled with the bow, changed the history of the world.

It’s hard to imagine, but as late as the 1950s, athletes could get kicked off a team if they were caught lifting weights. Coaches had long believed that strength training would slow down a player. Muscle was perceived as a bulky burden; training emphasized speed and strategy, not “brute” strength. Fast forward to today: the highest-paid strength and conditioning coaches can now earn $700,000 a year. Strength Coaching in America delivers the fascinating history behind this revolutionary shift.
College football represents a key turning point in this story, and the authors provide vivid details of strength training’s impact on the gridiron, most significantly when University of Nebraska football coach Bob Devaney hired Boyd Epley as a strength coach in 1969. National championships for the Huskers soon followed, leading Epley to launch the game-changing National Strength Coaches Association. Dozens of other influences are explored with equal verve, from the iconic Milo Barbell Company to the wildly popular fitness magazines that challenged physicians’ warnings against strenuous exercise. Charting the rise of a new athletic profession, Strength Coaching in America captures an important transformation in the culture of American sport.

During the first half of the twentieth century, the introduction of cheap or free recreation to the workplace provided a metaphorical place where ordinary working-class people of all races and genders gained access to physical leisure and developed bonds of camaraderie in the anti-fascist labor movement. Strikes and Strikeouts: Sports and the Labor Movement in the Mid-Twentieth-Century United States illustrates how this largely forgotten Labor Sports movement was critical in helping unions become forces for larger cultural change and essential to understanding the potency of the 1930-40s labor movement. Drawing from ten different labor and leftist social movement archives, Robinson strives to reconstruct the “people’s history." At its height, from the late 1930s to the early 1950s, the Labor Sports movement presented a real alternative to both apolitical and conservative sports and involved millions of working-class people. It was a key part of improving the lives of average Americans and helped build an anti-racist, anti-fascist, working class counterculture that helped change the United States through a strong labor movement. This movement brought higher living standards for working class people and the end of racial segregation in sports, which in turn aided the Civil Rights movement.

Appearance- and performance-enhancing drugs—specifically, anabolic steroids (APEDs)—provide a tempting competitive advantage for amateur baseball players. But this shortcut can exact a fatal cost on talented athletes. In his urgent book Suicide Squeeze, William Kashatus chronicles the experiences of Taylor Hooton and Rob Garibaldi, two promising high school baseball players who abused APEDs in the hopes of attracting professional scouts and Division I recruiters. However, as a result of their steroid abuse, they ended up taking their own lives.
In Suicide Squeeze—named for the high-risk play in baseball to steal home—Kashatus identifies the symptoms and dangers of steroid use among teens. Using archival research and interviews with the Hooton and Garibaldi families, he explores the lives and deaths of these two troubled young men, the impact of their suicides on MLB, and the ongoing fight against adolescent APED use by their parents.
A passionate appeal to prevent additional senseless deaths by athletes, Suicide Squeeze is an important contribution to debates on youth and sports and on public policy.

Summer Sports Camps 101: A Guidebook for Development and Operation is a comprehensive manual that will take the reader through all of the administrative nuances of creating and operating a summer sports camp. Funding, for the majority of athletic programs, is one of the most (if not the most) consequential element for administrators and coaches. With the limited amount of resource dollars available and ever-rising expenses, athletic programs have to make difficult financial decisions, which can have long-lasting ramifications on all of the organization's teams and programs. The purpose for this comprehensive guidebook is to provide professional practitioners (coaches and administrators) with the foundations and practical applications to develop and manage a cost-efficient, profitable summer sports camp. Simply stated, professionally-run camps can promote the institution's athletic programs and provide much needed resources and funds. As you will see, the book covers the entire subject from constructing administrative models today-to-day operations. This book could be used by all athletic teams and programs―whether they are starting a summer sports camp for the first time or have an established operation―in their development and execution of lucrative summer sports camps. The book can be used as an all-inclusive handbook for new sports camps or as a reference guide and idea generator for seasoned camp administrators.
Section I: Introduction examines the basic foundations and choices involved with operating a summer sports camp as well as conducting a feasibility study to examine the practicality of the venture.
Section II: Planning defines the clear benefits and uses associated with creating a summers ports camp plan.
Section III: Administration Systems provides indispensable camp system designs for registration, filing, and accounting that are universal to all camps.
Section IV: Human Resources discusses human resource management as an essential part of any summer sports camp. Concepts that have an unmistakable impact on the entire camp, such as selection, orientation, compensation and evaluation, are reviewed.
Section V: Marketing Systems furnishes detailed marketing and promotional ideas that can enlarge the camp's exposure as well as increase revenues.
Section VI: Risk Management and Camp Operations enables the reader to become a critical thinker in the area of risk management and camper safety.

An Irish working-class hero of Pittsburgh, Billy Conn captured hearts through his ebullient personality, stellar boxing record, and good looks. A light heavyweight boxing champion best remembered for his sensational near-defeat of heavyweight champion Joe Louis in 1941, Conn is still regarded as one of the greatest fighters of all time. Andrew O'Toole chronicles the boxing, Hollywood, and army careers of "the Pittsburgh Kid" by drawing from newspaper accounts, Billy's personal scrapbooks, and fascinating interviews with family. Presenting an intimate look at the champion's relationships with his girlfriend, manager, and rivals, O'Toole compellingly captures the personal life of a public icon and the pageantry of sports during the 1930s and '40s.
Carole Feuerman
The Artist Book Foundation, 2014
Realist sculptor Carole A. Feuerman's human-figure sculptures express a refreshing perspective on the mundane but intensely personal activities of modern life. her powers of observation and versatility find unique expression through various materials that include marble, bronze, vinyl, and painted resins, while she incorporates both ancient and contemporary methods in the creation of her works. Swimmers: Carole Feuerman is a gorgeous and shimmering glimpse at transitory, contemplative moments in time, often captured in a veil of clear resin that replicates tumbling water droplets.
In his astute and insightful essay, John Yau describes Feuerman's exquisitely rendered figures as subjects "caught in a moment of transition that radiates an intense eroticism." She evokes an inward life for her figures that invites our speculation, while revealing a mysterious chasm between them and the viewer that can never be plumbed. We cannot know their thoughts and perhaps that is exactly the point. Feuerman fuses the tactile nature of her sculpture with a visual verisimilitude that provides us a fleeting glimpse into private and isolated environments—women stepping out of the shower, in the rain, or swimming—that suggest a meditative bliss.

A memoir of discovery, loss, and wonder that shows us how to slow down
When psychologist and author Susan Baur first slipped into a Cape Cod pond with a snorkel, she wasn’t looking for transformation, just a swim. But beneath the surface, she discovered something extraordinary: minnows hiding among water lilies; fresh-water jellies like jewels and—most striking of all—painted, musk, and snapping turtles. Whether the turtles were buried in mud, teetering on a submerged branch, or drifting like ancient astronauts, they pulled her into a mysterious happiness she could not explain.
Learning to move slowly enough to see them became both her new discipline and her greatest joy. Each dive required patience, curiosity, and humility, and she learned to read the water, follow a subtle shadow, and anticipate the turtles’ rhythms without disturbing their world. As she mastered the art of swimming with turtles, Baur also fell in love with an older man whose companionship deepened her connection to the natural world. When he passed away, grief drove her deeper into the water. There, among the turtles, she found solace and purpose: a reason to keep diving, looking, and learning.
Over nearly two decades, Baur became a self-taught naturalist, children’s author (of The Turtle Sisters series), and unlikely environmental advocate, founding Old Ladies Against Underwater Garbage to protect the ponds she had grown to love. With humor, heart, and vivid observation, Baur shows that wonder isn’t reserved for the young or the lucky—it waits beneath the surface for anyone willing to slow down, look closely, and stay a while.
