Sex differences in association of race performance, skin-fold thicknesses, and training variables for recreational half-marathon runners

The purpose of this study was to investigate the association between selected skin-fold thicknesses and training variables with a half-marathon race time, for both male and female recreational runners, using bi- and multivariate analysis. In 52 men, two skin-fold thicknesses (abdominal and calf) were significantly and positively correlated with race time; whereas in 15 women, five (pectoral, mid-axilla, subscapular, abdominal, and suprailiac) showed positive and significant relations with total race time. In men, the mean weekly running distance, minimum distance run per week, maximum distance run per week, mean weekly hours of running, number of running training sessions per week, and mean speed of the training sessions were significantly and negatively related to total race time, but not in women. Interaction analyses suggested that race time was more strongly associated with anthropometry in women than men. Race time for the women was independently associated with the sum of eight skin-folds; but for the men, only the mean speed during training sessions was independently associated. Skin-fold thicknesses and training variables in these groups were differently related to race time according to their sex.     

Predictor variables for a 100-km race time in male ultra-marathoners

In 169 male 100-km ultra-marathoners, the variables of anthropometry, training, and prerace experience, in order to predict race time, were investigated. In the bivariate analysis, age (r = .24), body mass (r = .20), Body Mass Index (r = .29), circumference of upper arm (r = .26), percent body fat (r = .45), mean weekly running hours (r = -.21), mean weekly running kilometers (r = -.43), mean speed in training (r=-.56), personal best time in a marathon (r = .65), the number of finished 100-km ultra-runs (r = .24), and the personal best time in a 100-km ultra-run (r = .72) were associated with race time. Stepwise multiple regression showed that training speed (p < .0001), mean weekly running kilometers (p < .0001), and age (p < .0001) were the best correlations for a 100-km race time. Performance may be predicted (n=169, r2 = .43) by the following equation: 100-km race time (min) = 1085.60 - 36.26 x (training speed, km/hr.) - 1.43 x (training volume, km/wk.) + 2.50 x (age, yr.). Overall, intensity of training might be more important for a successful outcome in a 100-km race than anthropometric attributes. Motivation to train intensely for such an ultra-endurance run should be explored as this might be the key for a successful finish.     

Predictors of race time in male ironman triathletes: physical characteristics, training, or prerace experience?

The aim of the present study was to assess whether physical characteristics, training, or prerace experience were related to performance in recreational male Ironman triathletes using bi- and multivariate analysis. 83 male recreational triathletes who volunteered to participate in the study (M age 41.5 yr., SD = 8.9) had a mean body height of 1.80 m (SD = 0.06), mean body mass of 77.3 kg (SD = 8.9), and mean Body Mass Index of 23.7 kg/m2 (SD = 2.1) at the 2009 IRONMAN SWITZERLAND competition. Speed in running during training, personal best marathon time, and personal best time in an Olympic distance triathlon were related to the Ironman race time. These three variables explained 64% of the variance in Ironman race time. Personal best marathon time was significantly and positively related to the run split time in the Ironman race. Faster running while training and both a fast personal best time in a marathon and in an Olympic distance triathlon were associated with a fast Ironman race time.     

Physical training and personality factors as predictors of marathon time and training injury

On the basis of surveys completed by 105 male participants in a popular marathon, a multiple regression analysis was conducted to identify the variables contributing significantly to the prediction of final time. Overall prediction was successful, with R = .896, and training pace was the most important factor in the equation, speedier workouts being associated with faster marathon times. Final time was also related positively to best 10-km race time in the previous 12 mo. and repression-sensitization (faster runners being more sensitized), and negatively to maximum number of training miles in a single week, number of previous marathons completed, and number of days of training lost through illness or injury. Contrary to expectations, locus of control was not related to final time. Only 27% of the runners had lost training time through injury, but a discriminant analysis showed that, compared to those who had avoided this problem, the injured were younger, rested less, ran less in the week prior to the marathon, ran a slightly longer long run but ran it earlier before the race, and ran fewer runs of 20 miles or more. It is suggested that researchers should study the repression-sensitization variable and investigate injury in runners preparing for a marathon.     

Running as a way fat women re-story their bodies and construct a runner identity in a North American sociocultural context

AimThis research sought to identify the process by which women who identify as fat or as not having a typical athletic body construct an athletic identity and persist in their running and other athletic endeavors despite body size-related barriers.MethodsFrom an online recruitment effort, 19 North American women runners in larger bodies completed interviews in which they told the story of how they had become runners. A narrative analysis with a feminist, constructivist approach was conducted to identify story types.ResultsFour narrative types were identified: reclaiming the body, reclaiming health, space-making, and future-imagining. Through finding a size- and pace-inclusive running community, running persistently, and completing races, women relinquished the stories they’d believed that their bodies were not athletic since childhood and constructed an identity of runner in a fat body.ConclusionsThese women’s engagement in running is a personal form of resistance against those who define athletic and healthy as “thin” or “fit.” They have found a welcoming athletic community and have moved on to leadership where they are working to make running accessible to other women in bodies like theirs. Those reading these narratives should consider ways in which fat bodies have been excluded from athletics, as well as ways to support the work being done by women runners in fat bodies to redefine health and athleticism.     

Body esteem and body fat in British school children from different ethnic groups

The aim of the study was to examine the relationship between body esteem and body fat in British school children. Two hundred and seventy seven, 11–14-year-old children from central England took part in the study. Body esteem was measured using the Body Esteem Scale for children and percent body fat was determined by skin-fold measures. Results indicate that body esteem and adiposity were negatively related for the whole sample, for boys and girls and for White children, Black children and Asian children. Factorial ANOVA also indicated differences in body esteem according to gender and ethnicity. Boys and Black children had significantly higher body esteem than girls and Asian children respectively. Differences in body fat were also evident according to gender with boys being leaner than girls. No differences in body esteem or body fat were evident across school years.     

A comparison of ultra-endurance cyclists in a qualifying ultra-cycling race for Paris-Brest-Paris and Race Across America-Swiss cycling marathon

Ultra-endurance events test the adaptation of human physiology to extreme physical and mental demands, high levels of training, motivation, and physical conditioning among participants. To understand basic differences among participants according to the severity of the race, participants in qualifying events for two ultra-endurance cycling races, differing in length and intensity, were compared on measures of anthropometry, training, and support. One race was four times longer, required supporting teams, and racers typically had little sleep, which should lead to the qualifiers being substantially more highly trained than those from the shorter race. The qualifiers in the longer race had greater intensity in training while the qualifiers in the shorter race relied more on training volume. Different strategies and types of training reflected the different demands of the races. Future studies should evaluate personality and motivational differences in ultra-endurance events and between these athletes and athletes in other sports.     

Everyone can be a winner: The benefits of competing in organized races for recreational runners

ABSTRACT

Participants in the study were 404 recreational runners. At the end of each week for three months they used an online diary to describe their psychological well-being for the week (a total of 4046 weeks), and they indicated if they had participated in an organized race each week (a total of 1111 races). Multilevel modeling analyses (weeks nested within persons) found that well-being, defined in terms of self-esteem, self-efficacy, life satisfaction, positive affect, and depressed affect, was higher during weeks in which participants had run in an organized race than it was during weeks in which they had not run in an organized race. Moreover, well-being was positively related to self-evaluations of performance in races. For recreational runners, finishing an organized race may represent the achievement of a goal, an achievement that increases well-being and may help maintain or increase the motivation to keep running.     

Age, training, and previous experience predict race performance in long-distance inline skaters, not anthropometry

The association of characteristics of anthropometry, training, and previous experience with race time in 84 recreational, long-distance, inline skaters at the longest inline marathon in Europe (111 km), the Inline One-eleven in Switzerland, was investigated to identify predictor variables for performance. Age, duration per training unit, and personal best time were the only three variables related to race time in a multiple regression, while none of the 16 anthropometric variables were related. Anthropometric characteristics seem to be of no importance for a fast race time in a long-distance inline skating race in contrast to training volume and previous experience, when controlled with covariates. Improving performance in a long-distance inline skating race might be related to a high training volume and previous race experience. Also, doing such a race requires a parallel psychological effort, mental stamina, focus, and persistence. This may be reflected in the preparation and training for the event. Future studies should investigate what motivates these athletes to train and compete.     

Eating disorders in elite female distance runners: Effects of nationality and running environment

ObjectivesTo compare UK and Kenyan athletes and to examine the influence of nationality and involvement in elite distance running on the presence of eating disorders, eating disorder psychopathology and menstrual dysfunction, in young women.DesignIndependent groups, with nationality and running status as independent variables.MethodsElite female distance runners were identified based on their performances in track, road and cross-country events. Questionnaire packs were sent to UK athletes and Kenyan athletes were approached at race meetings or a training camp. In all, 82 UK and 75 Kenyan athletes participated (70% and 90% of those invited) along with 97 and 101 non-athlete, age-matched controls from the two countries. All participants completed the Eating Disorder Examination Questionnaire (EDE-Q) and assessments of dieting, mental health, self-esteem and menstrual function.ResultsUK women had significantly higher levels of eating disorder psychopathology and more probable present and past eating disorders than enyan women. Overall, 19.5% of the UK runners had a probable present or past eating disorder, confirming the results of our earlier study (Hulley & Hill, 2001). Kenyan runners had the lowest proportion of probable cases compared with all other groups and the least eating disorder psychopathology. Athletic participation was associated with less regular menstrual periods, regardless of nationality.ConclusionThese findings confirm that participation in distance running at an elite level does not in itself predispose to an eating disorder. Eating disorder risk is better represented as a combination of cultural values, elite sporting environment and person variables.     

Personality characteristics associated with aerobic exercise in adult males

Using an index of aerobic conditioning 23 adult male exercisers and 23 nonexercisers were identified. During individual interviews with each subject basic demographic data were obtained and blood pressure, resting pulse rate, and body fat were measured. All subjects completed Form A of the Sixteen Personality Factor Questionnaire (16PF). Statistically significant differences occurred on six primary factors and four Secondary dimensions of the 16PF. In comparison to the inactive subjects the exercisers, all of whom were joggers or runners, were more reserved, expedient, suspicious, forthright, liberal, and self-sufficient on the primary traits, and were more alert and independent, less discreet, and evidenced lower super-ego strength on the broader secondary patterns. The statistically significant training effects were lower pulse rate and less body fat, but did not include blood pressure.     

An Examination of Metacognitive Strategy Use and Monitoring Skills by Competitive Middle Distance Runners

This study investigated metacognitive strategy use by competitive athletes. Specifically, it tested the extent to which competitive middle-distance runners rely upon internally-focused metacognitive strategies versus externally-focused thoughts when they compete. In addition, the link between strategic knowledge and the regulation of such strategies during a novel self-paced task was investigated. Division I collegiate runners from the Midwestern U.S. (M age = 19.6, SD = 1.23) provided written responses to inventories about strategy use and completed a performance task requiring them to monitor and adjust their running pace. Results indicated an overwhelming tendency for the competitive runners in this study to report internally-focused strategies as opposed to externally-focused thoughts. The bulk of the thoughts that runners reported focused on either (a) monitoring bodily processes and form or (b) information management strategies that related to race tactics during competition. Furthermore, evidence was found for a link between self-report strategic knowledge and the ability to regulate one's performance on the self-paced task.     

A prospective comparison of lower extremity kinematics and kinetics between injured and non-injured collegiate cross country runners

Collegiate cross country runners are at risk for running related injuries (RRI) due to high training volume and the potential for aberrant lower extremity biomechanics. However, there is a need for prospective research to determine biomechanical risk factors for RRI. The purpose of this study was to prospectively compare ankle, knee, and hip kinematics and kinetics and ground reaction force characteristics between injured and non-injured cross country runners over a 14-week season. Biomechanical running analyses were conducted on 31 collegiate-cross country runners using a 3-dimensional motion capture system and force plate prior to the start of the season. Twelve runners were injured and 19 remained healthy during the course of the season. Peak external knee adduction moment (KAM), a surrogate for frontal plane knee loading, and peak ankle eversion velocity were greater in runners who sustained an injury compared to those who did not, and no differences were noted in ground reaction force characteristics, or hip kinematics and kinetics. Reducing the KAM and ankle eversion velocity may be an important aspect of preventing RRI.     

Examining the diversity of ultra-running motivations and experiences: A reversal theory perspective

ObjectivesThis study aims to add to literature on the phenomenology of ultra-running, an extreme form of long distance running. Through application of reversal theory, the study seeks to extend knowledge of the motivations and experiences of ultra-runners as well as approaches to understanding ultra-endurance sport more generally.DesignPost-positivist, qualitative, phenomenological.Method10 recreational ultra-runners participated in semi-structured interviews in which they were introduced to the eight metamotivational states of reversal theory and asked to discuss their running motivations and experiences.ResultsA thematic networks analysis revealed a propensity for participants to experience a diverse range of reversal theory states when running, embodying Apter’s (2007) concept of psychodiversity. Participants revealed an orientation to both states in each pair of the four metamotivational domains of reversal theory; serious/playful, conformity/rebellious, mastery/sympathy, and self/other. Participant accounts of experiencing playful (paratelic) and other-orientated (alloic-sympathy) metamotivational states were particularly important to ultra-running phenomenology and its differentiation from mainstream sport.ConclusionReversal theory has proven to provide an effective framework for exploring and theorising ultra-running phenomenologies. The psychodiversity documented by participants suggests that ultra-running and other ultra-endurance sports necessitate a diverse and dynamic metamotivational orientation. Application of this thesis to other ultra-endurance activities is encouraged.     

A comparison of body perceptions in relation to measured body composition in young Japanese males and females

The body composition of 139 Japanese females and 84 Japanese males (aged 18–30 years) was measured using anthropometry to assess gender differences in body perceptions in relation to their measured values. Participants were asked to rate perceptions of their own “heaviness” and “fatness” and these were compared to their BMI and percent body fat (%BF). Japanese females showed a significantly greater desire to lose body weight (−4.20 ± 0.6 kg) compared to males (0.27 ± 1.4 kg). Females also showed poor understanding of their “heaviness” and “fatness” in relation to actual body composition compared to males. The results confirmed distinct gender differences in body perception in relation to actual body composition and attitudes to weight management. Further promotion of “healthy” body image is recommended for the Japanese population.     

Comparing elite male and female distance runner's experiences of disordered eating through narrative analysis

ObjectivesResearchers have called for additional forms of theorizing and qualitative methodologies to explore disordered eating in athletes. The current study used social constructionism and narrative analysis to compare and contrast the disordered eating experiences of one male and female athlete.DesignNarrative inquiry was combined with an in-depth case study approach to explore the narrative and gendered construction of disordered eating in one elite male (age 19) and female (age 34) distance runner. The personal and cultural narratives drawn upon to construct meanings around the body, food and running and how these framed experiences were of interest.MethodsA structural and performative narrative analysis was conducted on four in-depth interviews (i.e., both runners participated in two separate interviews).ResultsBoth runners drew upon a performance narrative to construct running experiences and self-identities as elite athletes. When elite athletic identity became threatened by moments of perceived failure (e.g., poor performance, injury), disordered eating thoughts and behaviors emerged for both runners. Gendered narratives around the body, food and running further differentiated specific meanings and the emotional impact of these experiences for each male and female athlete.ConclusionsThis study extends quantitative and qualitative explorations of disordered eating in distance runners by highlighting additional understandings of the complex social, cultural and gendered construction of these experiences.     

Relationships of coping styles with type of sport

The purpose of this study was to ascertain whether the type of sport is associated with coping styles. 80 athletes (weightlifters, runners, swimmers, and triathletes) were administered the Coping Inventory for Stressful Situations. Analysis showed weightlifters had a lower mean score on Avoidance coping than the other groups of athletes. Differences concerning sex and ability were found as well.     

Ankle kinetics and plantarflexor morphology in older runners with different lifetime running exposures

Running promotes better cardiovascular health and has positive effects on the musculoskeletal system in older adults. However, older adults have lower ankle plantarflexor torques and positive powers during running, and exhibit changes in plantarflexor morphology than young adults. Since older runners who run as much as younger runners exhibit youthful ankle mechanical outputs, running exposure may preserve the locomotor factors that mediate running speed. The purpose of this study was to compare ankle mechanical output during running and plantarflexor morphological characteristics between older runners who have low or high lifetime running exposure. Ten older runners with low lifetime running exposure and nine older runners with high lifetime running exposure performed over-ground running trials at 3.0 m/s (±5%) while kinematic and ground reaction force (GRF) data were collected and used to compute joint angular kinetics. Right medial gastrocnemius morphological characteristics were assessed using ultrasonography at rest and during isometric contractions. Ankle torques, powers, and plantarflexor morphology were compared between groups. Older runners with different lifetime running exposures ran with similar ankle mechanical output (i.e. no effect of running exposure) (p > .05) and exhibited similar medial gastrocnemius morphology during isometric testing. The findings from this study demonstrate that lifetime running exposure does not appear to influence ankle mechanical output or plantarflexor morphology in middle-aged runners.
