Purpose:

To identify contributing factors to the incidence of illness for professional team-sport athletes, using training load (TL), self-reported illness, and well-being data.

Methods:

Thirty-two professional rugby league players (26.0 ± 4.8 y, 99.1 ± 9.6 kg, 1.84 ± 0.06 m) were recruited from the same club. Players participated in prescribed training and responded to a series of questionnaires to determine the presence of self-reported illness and markers of well-being. Internal TL was determined using the session rating of perceived exertion. These data were collected over 29 wk, across the preparatory and competition macrocycles.

Results:

The predictive models developed recognized increases in internal TL (strain values of >2282 AU, weekly TL >2786 AU, and monotony >0.78 AU) to best predict when athletes are at increased risk of self-reported illness. In addition, a reduction in overall well-being (<7.25 AU) in the presence of increased internal TL, as previously stated, was highlighted as a contributor to self-reported-illness occurrence.

Conclusions:

These results indicate that self-report data can be successfully used to provide a novel understanding of the interactions between competition-associated stressors experienced by professional team-sport athletes and their susceptibility to illness. This may help coaching staff more effectively monitor players during the season and potentially implement preventive measures to reduce the likelihood of illnesses occurring.

Background:

In light of evidence linking sedentary behaviors to health outcomes, there have been calls for the measurement of sedentary behavior in surveillance studies. This study examined the convergent validity of 2 self-report measures of sitting time and accelerometer-determined sedentary time (minutes/day of <100 counts/minute).

Methods:

44 adults wore an ActiGraph accelerometer for 7 days, during which they also recorded daily sitting time in a diary, in response to a single-item question. After 7 days, participants completed a new domain-specific questionnaire to assess usual weekday and weekend-day sitting time. Total sitting times recorded from the self-report measures were compared with accelerometer-determined sedentary time.

Results:

Total sitting time calculated from the domain-specific questionnaire did not differ significantly from accelerometer-determined sedentary time on weekdays (mean difference [±SE] = –14 ± 28 mins/day) and weekend days (–4 ± 45 mins/day, both P > .05). Sitting time was significantly underestimated using the single-item specific-day question on weekdays (–173 ± 18 mins/day) and weekend days (–219 ± 23 mins/day, both P < .001).

Conclusions:

When assessed via self-report, the estimation of total sitting time is improved by summing sitting times reported across different domains. The continued improvement of self-report measures of sitting time will be important if we are to further our understanding of the links between sedentary behavior and health.

Injury to the rectus femoris (RF) myotendinous complex is the most common location of quadriceps injury, due to combined loads of stretch and eccentric muscular activation. To our knowledge, open proximal RF repair has been reported, but a thorough description of postoperative rehabilitation and functional progression of athletic activity has not been described. This case report outlines the rehabilitation of a 30-year-old female following open proximal RF repair after 15 months of failed conservative treatment. Six months postoperatively she returned to competitive recreational soccer with no complaints.

Context:

The validity of physical activity (PA) self-report measures can be a problem when using these measures with target populations that differ from the population for which the measures were originally developed.

Objectives:

Describe an approach to further tailor PA self-report measures to a target community, and report on focus group and cognitive interview findings.

Process:

Topics relevant to culturally tailoring measures are discussed, including translation, focus groups, and cognitive interviews. We describe examples from our own work, including focus groups and cognitive interviews conducted to assess Latinos’ interpretations of PA questions derived from various epidemiological surveys that were developed in White communities.

Findings:

Findings from focus groups and cognitive interviews provide valuable information about the comprehension, interpretation, and cultural relevance of the PA questions to Latino communities.

Conclusions:

It is recommended that investigators collect formative data to better assess the equivalence of items being applied to a different cultural group. Guidelines for cultural attunement of self-report instruments are described to promote more uniform and rigorous processes of adaptation and facilitate cross-cultural investigations.

There is no criterion reference for assessing physical activity; therefore, clinicians may opt to use self-report measures or step activity monitors to determine physical activity levels. According to a 2008 systematic review by Prince et al, 20 patients often overestimate or

Purpose:

The purpose of this study was to validate the accuracy of self-reported (SR) training duration and intensity distribution in elite endurance athletes.

Methods:

Twenty-four elite cross-country skiers (25 ± 4 y, 67.9 ± 9.88 kg, 75.9 ± 6.50 mL · min−1 · kg−1) SR all training sessions during an ~14-d altitude-training camp. Heart rate (HR) and some blood lactate measurements were collected during 466 training sessions. SR training was compared with recorded training duration from HR monitors, and SR intensity distribution was compared with expert analysis (EA) of all session data.

Results:

SR training was nearly perfectly correlated with recorded training duration (r = .99), but SR training was 1.7% lower than recorded training duration (P < .001). SR training duration was also nearly perfectly correlated (r = .95) with recorded training duration >55% HRmax, but SR training was 11.4% higher than recorded training duration >55% HRmax (P < .001) due to SR inclusion of time <55% HRmax. No significant differences were observed in intensity distribution in zones 1–2 between SR and EA comparisons, but small discrepancies were found in zones 3–4 (P < .001).

Conclusions:

This study provides evidence that elite endurance athletes report their training data accurately, although some small differences were observed due to lack of a SR “gold standard.” Daily SR training is a valid method of quantifying training duration and intensity distribution in elite endurance athletes. However, additional common reporting guidelines would further enhance accuracy.

Background:

Advocacy informed by scientific evidence is necessary to influence policy and planning to address physical inactivity. The mass media is a key arena for this advocacy. This study investigated the perceptions and practices of news media professionals reporting physical activity and sedentariness to inform strategic communication about these issues.

Methods:

We interviewed media professionals working for major television, radio, newspaper and online news outlets in Australia. The interviews explored understandings of physical activity and sedentariness, attributions of causality, assignment of responsibility, and factors affecting news reporting on these topics. Data were thematically analyzed using NVivo.

Results:

Physical inactivity was recognized as pervasive and important, but tended to be seen as mundane and not newsworthy. Sedentariness was regarded as more novel than physical activity, and more likely to require organizational and environment action. Respondents identified that presenting these issues in visual and engaging ways was an ongoing challenge.

Conclusions:

Physical activity researchers and advocates need to take account of prevailing news values and media practices to improve engagement with the news media. These include understanding the importance of novelty, narratives, imagery, and practical messages, and how to use these to build support for environmental and policy action.

The purpose of this study was to determine if self-reported exercise status (exercise, nonexercise) and ambulatory status (aid, no aid) discriminate between balance performance and balance self-efficacy of older adults, ages 65 to 95 years. Participants were 14 males and 46 females in a retirement home that contained a supervised fitness center. An activities-specific balance confidence scale and three balance performance tests yielded data. Data from males and females were combined because independent t tests revealed no significant gender differences. The Mann Whitney U test revealed that (a) exercisers (M age = 83.4) scored significantly higher than nonexercisers (M age = 83.7) on all measures, and (b) nonaid users (M age = 83.5) scored significantly higher than aid users (M age = 83.7). Findings indicate that regular exercise (at least 30 min per day, 3 days per week) and ambulation without a cane or walker are descriptors of older adults with good balance performance and high balance self-efficacy.

Self-report measures of psychological states are commonly used in sport psychology research and practice, yet the possibility of response bias due to social desirability (repressive defensiveness) often has been overlooked. The present study was designed to examine whether or not a significant relationship exists between social desirability and competitive trait anxiety and the CSAI-2 subscales measuring state somatic anxiety, cognitive anxiety, and self-confidence. The participants were 58 female collegiate golfers representing 13 NCAA Division I universities. Pearson product-moment correlations indicated that competitive trait anxiety (−.24), self-confidence (.45, .38), and cognitive anxiety (−.24) appeared to be influenced by social desirability distortion. If the present findings are replicated in future studies using the SCAT, CSAI-2, and other inventories, the field of sport psychology may need to reexamine some of the theoretical and application conclusions drawn from previous research in which no attempt was made to eliminate data from subjects who may have distorted their responses.
