  • May 27th, 2011 WESTERN CAROLINIAN Page 2_ CAMPUS LIFE Western Carolina faculty, students test eneIsy mile theory in lab Wwe News Services Backpackers who take on . the challenge of hiking in the Southern Appalachian Moun- tains can attest to the fact that hauling a pack up a steep mountain trail is much more difficult than carrying one on level ground, and some West- ern Carolina University facul- ty members and students have put that notion to the test. A study that involved vol- unteers carrying a pack while walking on a treadmill set on an uphill grade was.used to test the energy mile theory first proposed by the late. American mountaineering legend Paul Petzoldt. Over- seeing the project was Maridy Troy, assistant professor in WCUs health and physical education program, and Mau- rice Phipps, professor of parks and recreation management, who also knew Petzoldt as a friend and mentor. Phipps first, met Petzoldt, and found out about his en- ergy mile theory in 1982, when Phipps, a young im- migrant from England, went on a Wilderness Education Association training trip in Wyomings Teton Mountains _ that was led by the renowned outdoorsman. Petzoldt first proposed his theory in his 1976 book - Teton Trails to help back- ' packers plan trips and cal- culate their energy needs on mountain trails. Petzoldt defined one ener- gy mile as the energy required to walk one mile on the flat. He recommended adding two energy miles for every 1,000 feet of elevation gain, so a person hiking one mile and 1,000 feet upward would use the equivalent of three energy miles, Phipps said. Petzoldts energy mile the- ory was just a reflection of the mountaineers gut feeling, Phipps said. The theory had never been tested in a labora- tory before the study began in WCUs Exercise Physiology Laboratory in the spring of 2010, Phipps said. To determine the valid-. ity of the theory, the study measured, the energy cost and perceived exertion for walk-. ing on flat ground, with and without a 44.5-pound back- pack, and up an elevation gain of 1,000 feet, with and with- out the backpack, through the collection of metabolic data, Phipps said. Twenty-four student, facul- ty and staff volunteers, includ- ing 12 males and 12 females, went through four testing ses- - sions as the research contin- ued into fall semester of 2010. The study results showed that the additional energy cost for ascending 1,000 feet ranged from 1.34 to 2.02 energy mile equivalents, for an average of about t.6 miles, compared to Petzoldts use of two energy miles for each 1,000 feet. The range revealed by the study was due to the hikers per- sonal weight differences, Phipps said. _ Tt is remarkable that Pet- zoldts energy mile theory is so close to the actual en- ergy cost measured during our study, Phipps said. In ' the field of outdoor education, its important for leaders to in- clude an estimation of energy requirements during the plan- ning of hiking trips. Phipps said the energy - required for hiking up steep * mountain trails would vary for individuals and groups, . and the variables of the trail < would also factor in, but he. recommends that backpackers | stick with Petzoldts idea of adding two energy miles for : every 1,000 feet of elevation gain when planning trips. Petzoldt, the founder of the + National Outdoor Leadership School who is considered to : be the father of outdoor edu- . cation in the United States, . later amended his. theory, stating that 1,000 feet of el- . evation gain is equivalent to four miles worth of energy for trail novices with expedition + packs in the Tetons. Petzoldt suggested adding three en-~ ergy miles, instead of two, per 1,000 feet of elevation gain in the North Carolina mountains . when he visitd the WCU campus to teach a WEA expe- ; dition course in 1987, ue said. * An article detailing ihe ta study titled The Validity of Petzoldts Energy Mile The- ~ ory has been published in: the Journal of Outdoor Rec-.: reation, Education and Lead-... ership.

English students inducted into Sigma Tau Delta honor society - - From Staff Reports i Twenty Western Carolina University students recently were inducted into Theta Sigma chapter of Sigma Tau Delta, an international Eng- lish honor society. Sigma Tau Delta recogniz- es outstanding students with a major or mihor in English _ who have a grade-point aver- age of 3.0 or higher in their English courses and who rank in the top 35 percent of their class. Inducted from WCU were Elizabeth Nissly of Cullowhee; Hanna Allen, Joshua Cole, Shelby Har- rell and Katherine Nelson of Asheville; Jessica Jaqua and Thomas Shepherd of Frank- lin; Anna Bischoff of Rocky Mount; Dasiey Carpenter of Rutherfordton; Justin Caudell PHOTO SUBMITTED Pictured are a handful of the newest members of the Theta Sigma chapter of Sigma Tau Delta. of Cashiers; Samantha Gam- -pel of Murphy; Wanda Gant of Etowah; Emily Goodman >| of Lawndale; Emily Kilpat-. rick of Andrews; Brittany - Lynch of Asheboro; Cath- erine McRae of Laurinburg; .. Rachel Moore of Claremont; :: Travis Mullen of Greensboro; Ashley Pennell of Statesville; and Mai Xiong of Candler. Christopher Rollins, honor society chapter president, led the ceremony, which was held on the WCU campus in the multipurpose room of : the A.K. Hinds University Center. Brian Gastle, WCU English department head, addressed the students and presented certificates and pins, and Bill Spencer, visit- ing assistant professor and the chapters faculty sponsor, be- stowed the societys red and black honor cords. WCU student chapter awarded for work} in safety, health field Erik Freitas, Contributing Writer Western Carolina Univer- : sity has been honored with a national award from. the American Society of Safety Engineers for best student chapter of the year, which comes with a $6,000 prize to be used for scholarships and student research. WCUs chapter was se- lected from a record 17 submissions for the 2011 Mine Safety Appliance Co. Outstanding Student Sec- tion Award, which will be presented at the 2011 Safety Professional | Development Conference in Chicago on Sunday, June 12. We were impressed with the caliber of the sections re- search, community involve- ment, and development and achievement of section goals Pie > zp ie GuaGae oO F e = T Wale Kea | O| Ss R ar A ae R a 2} [anf +[m]o] s/o] | SREBOES Sc = m]o|=[o]s]o]o]a|~ | fo}a]o]r]o|o|= aoa] )}o|=}ujols 0] 8) [2]=|NJa]olo, 2|=[0/o]0/o]n] 5/0 o}a|sr}o|sfo]=|o and objectives, said Aaron Bird, chair of ASSEs student section subcommittee. Founded in 1911, ASSE is the nations oldest profes- sional safety organization. Its more than 33,000 mem- bers manage, supervise and consult on safety, health and environmental issues in. in- dustry, insurance, govern- ment and education. ASSE has 17 practice specialties, 151 chapters, 28 sections and 58 student sections. We all value the initia- tive, collaboration and priori- ties of these students, said Linda Seestedt-Stanford, WCU interim provost and senior vice chancellor. I expect them to continue to be wonderful role models and mentors to other student groups. a 4 ;
