Researchers have noted that when taken to an excessive level, exercise may become addictive. This study investigated the risk of exercise addiction for triathletes using the Exercise Addiction Inventory (EAI; Terry, Szabo, & Griffths, 2004). The sample consisted of 1,285 male and female triathletes, ranging in age from 18–70 years old. Results indicated that approximately 20% of triathletes are at risk for exercise addiction, and that training for longer distance races (i.e., Olympic, Half-Ironman, and Ironman) puts triathletes at greater risk for exercise addiction than training for shorter races (i.e., Sprint). No significant association was found between the risk for exercise addiction and the number of years of participating. However, as the number of weekly training hours increased, so did a triathlete’s risk for exercise addiction. At-risk triathletes need greater clinical attention, and further research should be conducted to help clinicians develop awareness and appropriate interventions.

Detailed accounts of the training programs followed by today’s elite triathletes are lacking in the sport-science literature. This study reports on the training program of a world-class female triathlete preparing to compete in the London 2012 Olympic Games. Over 50 wk, she performed 796 sessions (303 swim, 194 bike, 254 run, 45 strength training), ie, 16 ± 4 sessions/wk (mean ± SD). Swim, bike, and run training volumes were, respectively, 1230 km (25 ± 8 km/wk), 427 h (9 ± 3 h/wk), and 250 h (5 ± 2 h/wk). Training tasks were categorized and prescribed based on heart-rate values and/or speeds and power outputs associated with different blood lactate concentrations. Training performed at intensities below her individual lactate threshold (ILT), between the ILT and the onset of blood lactate accumulation (OBLA), and above the OBLA for swim were 74% ± 6%, 16% ± 2%, 10% ± 2%; bike 88% ± 3%, 10% ± 1%, 2.1% ± 0.2%; and run 85% ± 2%, 8.0% ± 0.3%, 6.7% ± 0.3%. Training organization was adapted to the busy competition calendar (18 events, of which 8 were Olympic-distance triathlons) and continuously responded to emerging information. Training volumes were 35–80% higher than those previously reported for elite male and female triathletes, but training intensity and tapering strategies successfully followed recommended best practice for endurance athletes. This triathlete placed 7th in London 2012, and her world ranking improved from 14th to 8th at the end of 2012.

A Comparison of Anthropometry between Ironman Triathletes and Ultra-swimmersWe intended to compare the anthropometry of male and female Ironman triathletes with the anthropometry of male and female ultra-swimmers. Body mass, body mass index and body fat were lower in both male and female triathletes compared to swimmers. Body height and length of limbs were no different between the two groups. In the multi-variate analysis, in male triathletes, body mass (p=0.015) and percent body fat (p=0.0003) were related to race time; percent body fat was also related to the swim split (p=0.0036). In male swimmers, length of the arm was related to race time (p=0.0089). In female triathletes and swimmers, none of the investigated anthropometric variables showed an association with race time. We concluded that Ironman triathletes and ultra-swimmers were different regarding anthropometry and that different anthropometric variables were related to race time. We assume that other factors, such as training and equipment, as opposed to anthropometry, may better predict race time in male and female Ironman triathletes.

Pulmonary edema has been reported in SCUBA divers, apnea divers, and long-distance swimmers however, no instances of pulmonary edema in triathletes exist in the scientific literature. Pulmonary edema may cause seizures and loss of consciousness which in a water environment may become life threatening. This paper describes pulmonary edema in three female triathletes. Signs and symptoms including cough, fatigue, dyspnea, haemoptysis, and rales may occur within minutes of immersion. Contributing factors include hemodynamic changes due to water immersion, cold exposure, and exertion which elevate cardiac output, causing pulmonary capillary stress failure, resulting in extravasation of fluid into the airspace of the lung. Previous history is a major risk factor. Treatment involves immediate removal from immersion and in more serious cases, hospitalization, and oxygen administration. Immersion pulmonary edema is a critical environmental illness of which triathletes, race organizers, and medical staff, should be made aware.

Focusing on female triathletes, this study was an exploration of behaviors and attitudes that may lead to disordered eating among female triathletes. One hundred and eighty-eight female triathletes residing in the U.S. completed an Internet-based questionnaire comprised of measures for disordered eating, body size distortion and dissatisfaction, and food consumption. Statistically significant relationships were identified regarding Preoccupation with Weight and Food Consumption (r= 0.52, p=0.005), Oral Control and Food Consumption (r= 0.32, p=0.04), and Food Restriction and Food Consumption (r= −0.30, p=0.04). Body Size Distortion was also significantly correlated to Food Consumption (r= −0.19, p=0.01), especially among the Sprint distance competitors (r= −0.21, p=0.02). Based upon the findings we suggest food restriction, body size distortion, and disordered eating attitudes are apparent among female triathletes, especially those who are club level athletes and short distance competitors.

AbstractThe aim of this study was to determine the influence of body weight or lean body mass-based load on Wingate Anaerobic Test performance in male and female endurance trained individuals. Thirty-one participants (22 male cyclists and triathletes and 9 female triathletes) completed two randomized Wingate Anaerobic Test (body weight and lean body mass loads) in stationary start. There were no significant differences in power outputs variables between loads in any group. However, when comparing specific groups within the sample (e. g. cyclists vs cyclists) medium to large effect sizes were observed for Relative Mean Power Output (ES=0.53), Relative Lowest Power (ES=0.99) and Relative Power Muscle Mass (ES=0.54). Regarding gender differences, male cyclists and triathletes displayed higher relative and absolute power outputs (p<0.001) compared to female triathletes regardless of the protocol used. FI was lower in female triathletes compared to male triathletes and cyclists in body weight (p<0.001) and lean body mass (p<0.01) protocols. Body composition and anthropometric characteristics were similar in male cyclists and triathletes, but there were differences between genders. These results suggest that using either body weight-based or lean body mass-based load can be used interchangeably. However, there may be some practically relevant differences when evaluating this on an individual level.

The aim of this study was to investigate the prerace and during-race carbohydrate intakes of elite-level triathletes contesting draft-legal Olympic-distance triathlon (ODT) events. Self-reported prerace and during-race nutrition data were collected at 3 separate ODT events from 51 elite senior and under-23 triathletes. One hundred twenty-nine observations of food and fluid intake representing actual prerace (n = 62) and during-race (n = 67) nutrition practices from 36 male and 15 female triathletes were used in the final analysis of this study. Female triathletes consumed significantly more carbohydrate on the morning before race start when corrected for body mass and race start time than their male counterparts (p < .05). Male and female triathletes consumed 26% more energy (kJ/kg) and 24% more carbohydrate (g/kg) when commencing a race after midday (1:00–1:30 p.m.) than for a late morning (11:00–11:15 a.m.) race start. During the race, triathletes consumed less than 60 g of carbohydrate on 66% of occasions, with average total race intakes of 48 ± 25 and 49 ± 25 g carbohydrate for men and women, respectively. Given average race times of 1:57:07 hr and 2:08:12 hr, hourly carbohydrate intakes were ~25 g and ~23 g for men and women, respectively. Although most elite ODT triathletes consume sufficient carbohydrate to meet recommended prerace carbohydrate intake guidelines, during-race carbohydrate intakes varied considerably, with many failing to meet recommended levels.

The objectives of this study were to evaluate the prevalence of late potentials (LP) in female triathletes before and after prolonged strenuous exercise (PSE), and to determine whether LP are related to greater left ventricular (LV) dimensions and/or mass. Thirteen female triathletes were examined immediately before (Pre), one hour after (Post), and 24 to 48 hours after PSE (Recovery) using signal-averaged electrocardiography (SAECG). Late potentials were evaluated by two or more standard SAECG anomalies. Left ventricular dimensions and mass were measured Pre using two-dimensional echocardiography. Results revealed that no significant differences existed between Pre, Post, and Recovery in the SAECG parameters. Four athletes displayed LP during Pre. The incidence of LP during did not increase Post. There were no significant relationships between LV dimensions or mass and SAECG parameters. In conclusion, a small portion of female triathletes display LP before and after PSE, which are not worsened by PSE nor related to increased LV dimensions and/or mass. Keywords: signal-averaged electrocardiogram, triathlon, left ventricular dimensions, women

Background: In the past few decades, an increasing number of women have been participating in high-impact sports which involves jumping, landing and/ or running activities. Recent data have shown, however, that this kind of activity might be associated with adverse effects, including pelvic floor disorders. Nevertheless, there is very little in the literature about pelvic floor effects associated with endurance sports where high-impact exercise is performed at submaximal intensity for prolonged periods of time. Objective: The primary objective of the present paper is to describe the prevalence of pelvic floor dysfunction (PFD) in a female triathlete population. Methods: An anonymous on-line survey was administered from September 2015 to March 2016 to women who self-identified as triathletes. We used two validated questionnaires: the Pelvic Floor Distress Inventory Questionnaire short form (PFDI) and the Pelvic Floor Impact Questionnaire short form (PFIQ). In addition, respondents were asked for demographics (age, height, weight, occupation), general health status (medical history, pelvic/abdominal surgical history, pregnancy and birth history) as well as sport practice characteristics (duration of training, level of competition, number of hours spent per week swimming, cycling, and running), so as to characterise these female triathletes. The survey remained active online for seven months, during which time the majority of responses were obtained from having our survey on the IRONMAN December 2015 newsletter. The balance of responses came from various triathlon clubs which we had approached within Western Cape Province. Results: Sixty-seven female triathletes responded to the online survey which we designed on SurveyMonkey. The respondents were between the ages of 22 and 56 years, the mean being 37 years. They had a mean BMI of 22.6 kg/m2. None of them had any medical conditions known to increase the risk of PFD. Of the known surgical history risk factors, 74.6% had had no previous pelvic or abdominal surgery. In the cohort, 69.2% were nulliparous and 30.8% parous. Most of the respondents competed in the recreational age group (70.4%), compared with 29.6% who described themselves as being in the competitive age group. Over 94.4% of the participants had been involved in triathlon training for a period of more than 6 months. At the peak of their training, athletes described their weekly training regime as comprising a mean of 5.4 hours running, 3.9 hours swimming and 9.1 hours cycling. Of those who performed any form of 'core exercises', 29.6% performed pelvic floor exercises, 16.7% yoga, and 25.9% Pilates as part of their routine training. Eighty-two per cent of the triathletes had competed in the half IRONMAN and 37.8% in at least one full IRONMAN competition. The PFDI revealed a number of commonly occurring pelvic floor symptoms. The most reported urinary symptoms were urinary frequency, stress urinary incontinence (SUI) and urge urinary incontinence (UUI) (45.8%, 33.3% and 37.5%, respectively). The most reported colorectal symptoms were incomplete bowel emptying (41.7%), faecal urgency (43.8%), and flatal incontinence (41.7%). Pelvic organ prolapse symptoms were least reported, but those who had symptoms mostly experienced heaviness or dullness in the pelvic area (33.3%), pressure in the lower abdomen (31.3%) and a need for vaginal/rectal digitation in order to have or complete a bowel movement (25%). It was noteworthy to find that the nulliparous triathletes had more pelvic floor symptoms than the parous group. A higher prevalence of colorectal/rectal symptoms were reported by those who had had forceps deliveries. Colorectal symptoms were found to be slightly more prevalent in those who performed any pelvic floor exercises (PFE), yoga or Pilates than amongst those who did not. Even with the myriad symptoms reported, these women were not significantly bothered by their symptoms. Conclusion: It is apparent that PFDs are prevalent in the population reviewed, although the majority of individuals did not seem to be bothered by the symptoms that also did not appear to interrupt training or quality of life. For those who are concerned or troubled by the symptoms, it would be beneficial for them to be identified early so that management options can be offered to relieve the symptoms.

This study examines women's use of leisure as politics, especially as related to leisure as resistance, leisure and social worlds, and women's body image. Interviews were conducted with fifteen participants and coaches in two all-women's triathlon training groups in Austin, Texas. Both training groups prepared women for participation in the Austin Danskin Triathlon. Qualitative methods, grounded theory and constant comparison guided the interviewing and data analysis process. It was determined that Danskin trainees formed a social world which allowed them to redefine their bodies and redefine the tenets of organized sport. This finding centered around three major areas: initial involvement, community building and resistance. Most participants became involved initially for social reasons even though they often were out of shape or had not previously participated in athletics. Several participants experienced barriers to involvement commonly discussed in gender leisure studies including weight issues, "ethic of care" concerns and fear of not deserving leisure time. During participation in their training programs, the majority of trainees formed a community with their fellow participants which provided them with a safe place and a support structure. As a result, many Austin Danskin triathlon trainees were able to communally resist cultural and societal norms surrounding women's bodies and competitive athletics. As a group, trainees redefined the way women should look and placed function above form. Furthermore, they reclaimed sport from the male norm and instead demanded that it go beyond bigger, better, faster or stronger and instead focus on community, support and teamwork. The results of this study urge leisure providers to create programs that appeal to the whole person - not just the physical. As a result of the data, several hypotheses may be suggested for future study: Do women's only recreation programs provide a crucial link between social world formation and leisure as resistance? What other programs may produce similar results and why?

This study was to explore the perception of the menstrual cycle in domestic female triathletes. The research methodology utilized one on one in-depth interviews and a semi-structured survey. Use the questionnaire to collect data and discuss it after integration. There are five results as follows. 1. The player with normal menstrual cycle, low frequency of dysmenorrhea and stable mood, whose results of participating in the competition during the physiological period are similar or better than usual. 2. All players have had dysmenorrhea, but they have no active action to care herself. Most of them just took painkillers or just Endure the pain. Only a few people have turned to medical care. In addition to avoiding ice drinks and going to bed early, there is no special self-care. 3. The coach has no record for the female menstrual period, and has not adjusted the training due to the change of the menstrual cycle. 4. None of the interviewed participants measured the basal body temperature. Players use the mobile app to record the menstrual cycle, but do not understand the relevant information such as ovulation. They also don't understand the changes in the menstrual cycle to hormones and the possible impact on exercise performance. 5. The players followed the physiological and natural operation and did not alter the menstrual cycle due to the competition. Race as usual during the menstrual period. Use tampon during training and competition due to breathable comfort, not easy side leakage and less friction. There are also players who choose not to use any hygiene products at all during the competition.

The purpose of this investigation was to determine whether alterations in p-receptor responsiveness occur as a result of a single bout of prolonged strenuous exercise (PSE), and whether the myocardium of males and females responds differently to PSE. We examined nine male and eight female triathletes during three separate sessions: before, immediately after, and 24h following a half-ironman triathlon. Athletes were assessed during each session using dobutamine stress echocardiography. Steady-state graded infusions of dobutamine were used to assess p-adrenoreceptor responsiveness. Slopes calculated from linear regressions between dobutamine doses and changes in heart rate and contractility for each subject were used as an index of (3-adrenoreceptor responsiveness. Fractional shortening decreased from baseline after the race in both males and females, with the decrease greater in males (males: 54.1 ±2.1 to 50.7 ± 3.4% vs. females: 55.4 ± 2.7 to 53.3 ± 2.5 %). Despite no change in preload, systolic function (stress-shortening relationship) was significantly decreased in males and females following PSE. The amount of dobutamine necessary to increase HR 25 beats min⁻¹ (males: 29.6 ± 6.6 to 42.7 ± 12.9 μgkg⁻¹min⁻¹ vs. females: 23.5 ± 4.0 to 30.0 ± 7.8 ugkg⁻¹min⁻¹) and contractility 10 mmHg-cm- 2 (males: 20.9 ± 5.1 to 37.0 ±11.5 μg kg⁻¹min⁻¹ vs. females: 22.6 ± 6.4 to 30.7 ± 7.2 μg kg⁻¹ min⁻¹) was significantly greater in both males and females post-race, with the amount of drug necessary to induce this change significantly greater in males. These results provide evidence that an acute bout of PSE results in reduced LV systolic function and dobutamine responsiveness in both males and females and that these alterations occur to a greater extent in males.
