Fitness Counseling for the College Woman: These Are Not Her Mother’s Norms! By N. Jean Dalton, Dana Ensley, and Julie Wallace Most university recreation centers offer some form of fitness assessment service to both their undergraduate and graduate student populations. These assessments typically include evaluation of each of the major fitness components — cardiovascular endurance, muscular strength and endurance, flexibility, and body composition. Following assessment of these components, the student is informed of his/her fitness classification and receives a recommended exercise program based on the results. In many instances, the norms used for the fitness classification of these students are those provided by the American College of Sports Medicine (ACSM), which are based on two separate age-related categories, the under 20 and 20-29 year divisions. Since the average undergraduate and graduate student is between 17-25 years of age, the ACSM norms do not provide a single normative distribution. In addition, currently used fitness classifications utilize category headings such as poor and fair which may be disheartening, especially for de-conditioned female students who are already leery about beginning an exercise program. Therefore, the purpose of this research was two-fold: 1) to determine a single normative distribution for 17-25 year-old college female on a variety of commonly used fitness tests; and 2) to develop more user-friendly categories for reporting fitness performance. The intent was to establish more accurate normative data and create a more positive climate during the post-test consultation in a college or university fitness setting. The test battery used combined protocols for each of the major components of fitness including the YMCA sub-maximal ergometer test, 1-RM bench and leg press, curl ups, push ups, trunk flexion, shoulder elevation, and a 3-site body composition test. Testing was performed on 377 female undergraduate and graduate students between the ages of 17 and 25. Normative data including means and standard deviations were determined. In addition, five fitness categories (performance, fitness, healthy, potential risk, and at risk) were established for each of the tests administered. Category descriptors were designed to help foster a supportive atmosphere during the post-test consultation. The integra- 19 20 RECREATIONAL SPORTS JOURNAL • VOL 26 • NO 1 tion of these findings into a college-based fitness assessment program may help to create a more reassuring climate and thus positively impact exercise program adherence rates of female college students. M ost colleges and universities today offer some form of fitness assessment service to their student population, typically through an academic department of physical education (kinesiology), student health services, and/or the institution’s recreational program. Many of these programs employ staff or student personnel whose major responsibility includes fitness assessment of both undergraduate and graduate students representing a wide range of fitness levels. The battery of fitness tests most commonly recommended for an overview of a student’s fitness level include evaluation of each of the major fitness components — cardiovascular endurance, muscular strength, muscular endurance, flexibility, and body composition. Once these tests are administered, the student learns his/her fitness category or percentile ranking in each of the major areas, then receives a recommended exercise program based on those results. The most frequently referenced fitness categories used when developing exercise prescriptions for individuals between the ages of 20-29 years (1, 2, 4, 11) were established from data collected by the American College of Sports Medicine (1). These ACSM norms are used extensively to assist fitness personnel in determining an individual’s potential weaknesses. However, the use of these general population norms for college students, especially for college-aged women, poses at least three general concerns. The first is the age difference between the typical college-aged student and the population on which the currently used norms were based. Since the ACSM norms were established for a large portion of the population, their age categories were based by decade (i.e., < 20, between 20-29, 30-39 years of age, etc). Typically, college freshmen, sophomores, and juniors would be younger than 20 years, and would represent a large percentage of any college population. However, college seniors and graduate students are typically over the age of 20, but fewer than 25 years of age. Therefore, for college fitness centers to focus on students between the ages of 17-25 years, the use of the ACSM norms for the under-20 and 20-29 year-old age groups does not offer a single normative distribution. Second, our experience in exercise assessment indicates that scores for college-age females on two tests commonly used as an estimate of muscular strength (the bench press and leg press), do not exhibit the predicted normal distribution when using the ACSM fitness category for 20 to 29-year-old females. Instead, college-aged females tended to perform disproportionately in the poor category on the bench press and in the excellent category on the leg press. These DALTON, ENSLEY, WALLACE observations led us to develop new strength norms more appropriate for the college-aged female population. (3) A third concern with using the ACSM norms for college females is with the category labels that were established and continue to be used by many fitness facilities. Category headings such as fair or poor can be very disheartening for students who are already leery about beginning an exercise program. Even the more recent adoption of percentile rankings can be discouraging for students who score in the lower rankings. If one of the goals of a fitness program were to motivate and encourage participation, then user-friendly categories would seem more appropriate. With these concerns in mind, the goal of this research was two-fold: 1. To determine normative percentile data for college females within the 17 to 25-year-age range on a variety of commonly used fitness tests. 2. To develop more user-friendly categories for reporting fitness performance. The intent was to establish more accurate normative data, and create a more positive climate during the post-test consultation in a college and university fitness setting. Test Procedures The fitness tests battery focused on tests for each of the major components of fitness and included the following: cardiovascular endurance (cycle ergometer protocol), muscular strength and endurance (1-RM bench and leg press tests, and the curl up and push up field tests), flexibility (trunk flexion and shoulder elevation), and body composition (3-site skinfold technique). These tests represent protocols used regularly in college and university fitness facilities. The subjects included 377 female undergraduate and graduate volunteers who were between the ages of 17-25 years of age. Although these volunteers were students who sought information about their fitness status, they provided a wide range of reasons for being tested, including weight management, sports’ training, stress management, and overall fitness concerns. All of the participants completed a full fitness assessment with the university recreation fitness assessment staff at James Madison University. An ACSM-certified supervisor trained the staff members in charge of the testing, who were also knowledgeable of each protocol used. Following familiarization with the assessment procedures, each individual signed an informed consent before performing the tests described below. Cardiovascular Endurance Component: A sub-maximal test was used to determine the norms for cardiovascular endurance. The YMCA cycle ergometer protocol was followed using an 818E Monark cycle ergometer. The YMCA 21 22 RECREATIONAL SPORTS JOURNAL • VOL 26 • NO 1 protocol consists of two to four 3-minute stages during which heart rate and blood pressure measurements are recorded. Heart rates should be recorded at the final 15 seconds of each minute of each stage. Blood pressure is also recorded in the final 30 seconds of the stage. This test is terminated when the subject reaches a steady state heart rate above 110 beats/min for two stages or 85 percent of estimated maximum. It is also advisable to use an RPE scale and blood pressure readings to determine any contraindications for continuing the test. Once a heart rate above 110 beats per-minute is maintained for two stages, a linear relationship is determined between heart rate and workload. This relationship is used to calculate estimated VO2max, which is extrapolated from the linear relationship found by plotting heart rates and workload. (4) Muscular Strength Component – Leg Press and Chest Press: The protocols used for determining upper body and lower body strength were adapted from the procedures described by Jackson, Watkins, and Patton (5) and recommended by ACSM (1). The student should become familiar with the equipment and the procedure before any testing begins. The equipment used in establishing our norms was part of the Cybex Classic line, however, any standard line of equipment can be used. In order to avoid possible injury, each participant should also follow a standardized warm-up period before testing. Warm-up sets can be established at 50 percent and 75 percent of an estimated 1-RM as suggested by Wathen (12). Once the testing begins, the spotter helps the student assume the starting position with the arms or legs fully extended. Following the procedure described in Dalton and Wallace, the student then performs a maximal lift at either the chest (bench), or the leg press stations (3). Adequate recovery should be allowed between the two tests, using a 2-3 minute rest interval between trials as suggested by Semenick (11). Once the 1-RM (in lbs.) has been established for each participant for the bench and leg press, the scores should be recorded relative to the student’s body weight as follows: Weight lifted Body weight (2) The values for both the bench and leg press are then recorded as the ratio value of the weight lifted to the student’s body weight. Muscular Endurance Component – Curl-Ups: The measurement technique used to estimate muscular endurance was the curl-up field test. In the past, the full sit-up protocol was most often used for determining muscular strength, however, recent evidence shows that the partial curl-up protocol is much safer in preventing potential back injury and is just as effective in estimating a person’s abdominal endurance. In the starting position, the student lies on her back with the knees flexed at a 90-degree angle, head off the floor with the chin DALTON, ENSLEY, WALLACE approximately 1-2 inches from the chest. In this position, her fingertips should be touching a strip of masking tape placed perpendicular to the body. After flattening out the low back region, the individual curls the upper spine until the fingertips touch a second strip of tape placed 8 cm from and parallel to the starting tape. The student then uncurls the torso until the scapulae touch the mat without allowing the head to touch. This form should be maintained throughout the testing. The student is asked to complete as many curl-ups as possible in one minute. A complete curl-up is recorded each time the student touches the second tape strip and returns to the starting position. This test has been shown to be an effective functional measurement of abdominal strength. (7) Muscular Endurance – Push-Ups: The push-up field test is typically administered with females in the modified “knee” position. Therefore, the norms we have developed have used this position. The females perform the action in a bent-knee position with buttocks down, back straight, and hands approximately shoulder width apart. A spotter should watch the student closely to ensure that the proper technique is maintained throughout the test. The student lowers the body until her upper arms are parallel to the floor, and then returns to the starting position with arms completely extended. This position is different from the original protocol (chest touching the spotter’s closed fist, which is placed on the floor beneath the student) to increase the comfort level of the female. The action should be done in one continual motion. The score is recorded as the total number of push-ups performed in the proper position until the student reaches exhaustion. (2, 4) Flexibility Component – Trunk Flexion: Trunk flexion was measured using the sit and reach technique. The student sits on the floor with his or her legs extended, shoes off, and toes pointed upward. The feet should be placed approximately 10 – 12 inches apart with the bottom of the feet against the box. The 15-inch mark of the measure stick is positioned at the edge of the box facing the participant. The student then places the index fingers of both hands together, palms down and reaches slowly along the yardstick to the farthest possible position. Movement should be slow and controlled with no bouncing. The student should breathe normally during the test and refrain from holding his/ her breath. Three trials are conducted and the best score recorded to the nearest one eighth of an inch. (1) Flexibility Component – Shoulder Elevation: In order to measure shoulder elevation, arm length and hand positions must first be determined. The student should stand with both arms to the sides, palms supinated and holding a yardstick with a loose, but firm grip. The position of the hands on the yardstick is then recorded and used to determine the grip the individual will use 23 24 RECREATIONAL SPORTS JOURNAL • VOL 26 • NO 1 during the test. While maintaining this position, the student’s arm length is measured in inches from the acromion process to the upper edge of the yardstick and then recorded and used later in the calculations. Once arm length has been measured, the student lies on the floor in a prone position with her arms straight forward gripping the yardstick (palms down) at the same positions marked earlier. The student raises the stick upward as high as possible while keeping the chin on the floor and the elbows and wrists straight. The distance from the stick to the floor is then recorded in inches. The score for shoulder elevation is determined by multiplying the best of three trials by 100 and dividing the product by the arm length as follows: Stick height X 100 Arm length (1) Body Composition Measurements: Body composition was determined using the three-site skinfold measurements as described by ACSM. (1) All the body composition measurements were taken on the right side of the student’s body using a Lange caliper. The females were tested at the triceps, suprailiac and the anterior thigh. (2) Values from the three sites were totaled and body fat percentage was estimated using the tables developed by Pollock, Schmidt and Jackson. (9) Determination of the Norms and Categories: The completed data was used to establish normative rankings for the female students, including determination of means and standard deviations for each of the tests selected. The data was also used to calculate test categories to assist fitness personnel in their analysis. The healthy category was established by calculating one standard deviation around the mean score. Subsequent categories above and below the healthy category were calculated as one standard deviation above or below the mean score in each of the respective categories. The highest and lowest categories were established as two standard deviations above the respective mean score. Our experience shows that category labels can be instrumental in determining the atmosphere of a post-test consultation. This is especially true for female students who may be particularly sensitive about their body image. Category descriptors such as poor or obese are frequently interpreted by the student as a near-hopeless situation and can create a very negative motivational climate. On the other hand, generalized category labels such as average or needs work can be difficult for a student to personalize and thus may not be helpful in motivating a student to start an exercise program. After years of testing, we have found that the labels and norm descriptors identified here best foster a productive and motivating atmosphere during the post-test consultation. These category labels can effectively convey the student’s strengths and challenges without creating DALTON, ENSLEY, WALLACE undue negative connotations. Therefore, it is recommended that college or university fitness personnel use these category labels when discussing a student’s fitness level. Norm descriptors specific to each fitness component have been provided. The categories of performance, fitness, and healthy are generalized for cardiovascular endurance, muscular strength, muscular endurance, and flexibility as follows: Performance: A female in this category has the ability to take on the demands of daily life, including vigorous physical activities such as athletics or training for a specific sporting event. She can accommodate unexpected physiological stress without undue fatigue and may benefit from a higher quality of life. Fitness: A female in this category has the ability to take on the demands of daily life as well as moderate to vigorous physical activity and unexpected stress without undue fatigue. Healthy: A female in this category has the baseline requirements to reduce her risk of chronic disease and lower her incidence of musculoskeletal injuries. The categories of potential risk, at risk, potential limitations and limitations vary for each fitness component and have been described separately. In addition, the body composition norms were developed separately due to the unique physiological characteristics associated with that fitness component.

Having an extremely low level of body fat may lead to physiological complications such as risk of heart or other major organ failure. In females, low body fat percentages may also result in loss of menses and an early onset of osteoporosis. PERFORMANCE/FITNESS: This range has been divided into two descriptive norms. The lower level of the range designates the body fat percentage that represents a “fit” individual. The upper level of the range represents the optimal body fat percentage recommended to per form in certain sport-related activities. HEALTHY: At this level of body fat, a female may be free from diseases that are directly or indirectly linked to fat in the body (see those listed under the potential risk category). POTENTIAL RISK: This level of body fat may create potential risk for cardiovascular disease, diabetes, high blood pressure, and other health problems, which may be related directly or indirectly to the level of body fat. AT RISK: This level of body fat is indicative of a very high risk for cardiovascular disease, diabetes, high blood pressure and other health problems, which are directly or indirectly related to the level of body fat. An Explanation of the Norms and Categories It has been our experience that if descriptions and explanations are not given during the post-test consultation, the student tends to assume the worst about herself and her low fitness scores. Therefore, we recommend that college and university fitness assessment personnel use the category labels and descriptors provided. It is also helpful to let a student know that test performance is compared only to population norms for developing her exercise prescription. Although the norm labels can be useful in giving a general picture of the student’s fitness level, true success is seen when students focus on improving personal baseline scores. Note: The research was done based on the Fifth edition of the ACSM’s Guidelines for Exercise Testing & Prescription. The Sixth edition recommends a change in the protocol for the curl-up test. Depending on which edition of the ACSM’s recommended fitness tests you use, will determine if you will utilize the norms DALTON, ENSLEY, WALLACE and categories listed in this article. Future research will determine if the Sixth edition of the ACSM’s Guidelines for Exercise Testing & Prescription applies to the college-aged female. Summary Today’s college student is aware of the importance that fitness plays in his/ her total well-being. Most university recreation facilities have become sensitive to that awareness and now offer fitness assessments as a part of its regular services. In order to ensure that students will adhere to a prescribed exercise program, it is important that the fitness assessment is accurate and that the consultation experience provides a positive learning experience. This is particularly true for the female college student who is sensitive about her physical appearance. Therefore, the purpose of this research was to determine more accurate normative data for the college female population, including both undergraduate and graduate students within the ages of 17-25 years. In addition, we have tried to develop more user-friendly categories for reporting fitness performance in the hopes of improving the post-test consultation experience. By integrating this process into your fitness assessment program, a more positive climate and working relationship with your clients may be created. This may go a long way towards positively affecting exercise program adherence rates of your female college students. 29 30 RECREATIONAL SPORTS JOURNAL • VOL 26 • NO 1 REFERENCES American College of Sports Medicine.
