This paper reviews the descriptive epidemiology of physical activity in adolescents. Large population-based studies were reviewed, along with smaller studies using objective monitoring of physical activity. Estimates showed that adolescents engage in physical activity of any intensity for a mean of one hour per day. Approximately two thirds of males and one quarter of females participate in moderate to vigorous activity for 20 min 3 or more days per week. Activity levels decline with increasing age across adolescence, and this decrease is more marked in females than in males. Comparison of these data to physical activity guidelines for adolescents suggests the vast majority are meeting the guideline of accumulating physical activity. However, a substantial number of males, and the majority of females, are not meeting the guideline for moderate to vigorous physical activity.

Background:

Little is known about the epidemiology of dog sport–related injuries. This study examines injuries among handlers and dogs in the sport of dog agility.

Methods:

A cross-sectional pilot study captured data on demographics, exposures, and injury for a sample of agility handlers and dogs. Logistic regressions predicted odds of injury.

Results:

Survey of 217 handlers and 431 dogs identified 31 handler injuries (1.55 training injuries per 1000 hours, 2.14 competition injuries per 1000 runs) and 38 dog injuries (1.74 training injuries per 1000 hours, 1.72 competition injuries per 1000 runs). Handlers most commonly injured knees (48.4%) and lower trunk (29.0%). Most common diagnoses were strains (51.6%) and sprains (32.3%). Obese handlers had increased odds of injury compared with normal weight handlers (OR = 5.5, P < .001). Dogs most commonly injured front paws (23.7%) and shoulders (15.8%). Most common diagnoses were strains (44.7%) and cut/scrapes (21.1%). Injury was positively associated with dog’s age (P < .05). Handlers more commonly reported positive physical, emotional, and social motivations for participation than competitive.

Conclusions:

Despite many health benefits, dog agility poses a risk of injury to both handlers and dogs. Future research on specific mechanisms of injury should drive evidence-based injury prevention strategies.

Background:

Analysis of the 2005–2006 National Health and Nutrition Examination Survey (NHANES) accelerometer data provides the descriptive epidemiology of peak 30-minute cadence (defined as the average steps/min recorded for the 30 highest, but not necessarily consecutive, minutes in a day) and peak 1-minute cadence (defined as the steps/min recorded for the highest single minute in a day) by sex, age, and body mass index (BMI).

Methods:

Minute-by-minute step data were rank ordered each day to identify the peak 30-minute and 1-minute cadences for 3522 adults (20+ years of age) with complete sex, age, and BMI data and at least 1 valid day (ie, 10/24 hours of accelerometer wear) of accelerometer data. Peak values were averaged across days within participants by sex, age, and BMI-defined categories.

Results:

U.S. adults average a peak 30-minute cadence of 71.1 (men: 73.7, women: 69.6, P < .0001) steps/min and a peak 1-minute cadence of 100.7 (men: 100.9, women: 100.5, P = .54) steps/min. Both peak cadence indicators displayed significant and consistent declines with age and increasing levels of obesity.

Conclusions:

Peak cadence indicators capture the highest intensity execution of naturally occurring ambulatory activity. Future examination of their relationship with health parameters using cross-sectional, longitudinal, and intervention designs is warranted.

Context: Prevalence studies have been carried out widely on elite volleyball players. However, the extent to which specific prevention strategies are used and the influence of the sport equipment on the occurrence of injuries have been sparsely investigated. Objective: To describe the prevalence of injuries sustained during 1 season in elite Spanish volleyball leagues and to investigate the association of injuries with factors such as player court position, injury mechanism, type of shoes used when playing, or participation in prevention activities. Design: Descriptive cross-sectional epidemiology study: observational study. Setting: European elite professional volleyball. Participants: Professional volleyball players from the elite Spanish volleyball league. Main Outcome Measures: A self-report questionnaire assessed the presence of injury during a volleyball season. Questions included the type of injury, its anatomic location, participation in prevention strategies, shoe type, the injury mechanism, the season period, the period of leave, and the treatment received. Results: In total, 490 players (71.2% response rate) completed and returned the questionnaire. The injury prevalence was 66.9%, and the average of injuries per player was 0.94 (0.85) (range: 0–4). Most Spanish elite volleyball players participated in prevention programs during the season (90.3%) and played volleyball with low-top shoes (83.6%), but these factors were not associated with the prevalence of injuries (P > .05). The anatomic regions with the most injuries were the ankle, knee, and shoulder; the most common types of injury were sprains, tendinopathies, and strains, usually occurring during blocking and attack actions during the in-season period. Conclusions: Despite most elite volleyball players participating in prevention programs, the results reveal a high injury prevalence. Further prospective research on the effectiveness of prevention strategies in elite volleyball is needed.
