Clinical Scenario Widespread patient-reported outcome (PRO) use in athletic training is still marginal. 1 As sport injury pathologies tend to affect and are reported for individual body parts (e.g., ankle, knee, etc.) or more broadly across regions (e.g., the upper or lower extremity), 2 it is

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

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

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.
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.
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.
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.

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.

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.

Wearable accelerometer-based activity monitors (AMs) are used to estimate energy expenditure and ground reaction forces in free-living environments, but a lack of standardized calibration and data reporting methods limits their utility. The objectives of this study were to (1) design an inexpensive and easily reproducible AM testing system, (2) develop a standardized calibration method for accelerometer-based AMs, and (3) evaluate the utility of the system and accuracy of the calibration method. A centrifuge-type device was constructed to apply known accelerations (0-8g) to each sensitive axis of 30 custom and two commercial AMs. Accelerometer data were recorded and matrix algebra and a least squares solution were then used to determine a calibration matrix for the custom AMs to convert raw accelerometer output to units of g’s. Accuracy was tested by comparing applied and calculated accelerations for custom and commercial AMs. AMs were accurate to within 4% of applied accelerations. The relatively inexpensive AM testing system (< $100) and calibration method has the potential to improve the sharing of AM data, the ability to compare data from different studies, and the accuracy of AM-based models to estimate various physiological and biomechanical quantities of interest in field-based assessments of physical activity.
