Summary: In collegiate cross country runners, low step rate is an important risk factor for bone stress injury. Increasing step rate is associated with decreased risk of BSI.

Summary: The study found that there were no significant differences in the time spent in different training intensity zones between male and female collegiate cross-country runners. However, two female subjects experienced performance decrements and trained proportionally more in zones 2 and 3 compared with the overall group, suggesting potential detriments of group training for some collegiate runners.

Summary: The study investigated whether dynamic postural control differs in individuals with a history of running-related injury or those who go on to sustain a running-related injury. The results showed that regardless of injury history, the non-dominant limb demonstrated better postural stability indices. An interaction was observed between limbs and history of injury for the anterior-posterior time to stabilization for the lateral task. However, no clear differences were seen between injured and uninjured runners, suggesting that dynamic postural stability may be altered in individuals with a history of a running-related injury, but not related to subsequent injury.

Summary: The majority of collegiate cross-country runners did not meet the recommended daily energy, calcium, and vitamin D intake. Higher incidences of lumbar spine BMD were found in male and female runners with lower calcium and vitamin D intakes below minimum requirements, as well as in women with caloric intake below the required level. Some runners were identified as having osteopenia and osteoporosis, indicating a need for future longitudinal studies.

Summary: This study investigated the degree of asymmetry in biomechanical variables associated with injury, the effect of speed on asymmetry, and the differences in pre-season measures of asymmetry between injured and healthy runners. The findings suggest that running biomechanics exhibit a high degree of symmetry across different speeds and caution should be exercised when linking injury to asymmetry.

Summary: The study found that asymmetries during running are related to efficiency and energy expenditure. Among collegiate cross country runners, asymmetries do not change with years of eligibility, but some asymmetries are associated with personal records.

Summary: There were no significant differences in cartilage outcomes among collegiate runners, recreational runners, and controls. A larger peak external knee flexion (KFM) in recreational runners was associated with lower medial femoral cartilage echo-intensity, while a greater self-reported running amount in collegiate runners was associated with higher medial and lateral cartilage echo-intensity. The relationship between running kinetics, running amount, and knee cartilage characteristics may differ between collegiate and recreational runners.

Summary: The majority of collegiate endurance runners regularly use one or more dietary supplements, with specific usage patterns varying based on sex, history of bone stress injury, and bone mineral density.

Summary: This study validates the validity and reliability of wearable devices in measuring vertical oscillation (VO) during running. There are significant differences in VO measurements among different wearable devices, but they are significantly correlated and consistent with video analysis.

Summary: This study compared bone health between distance runners with lower limb bone stress injuries (BSI) and those without injuries. The DXA scans of injured runners before incidence indicated lower bone mineral density (BMD) compared with noninjured runners. Shorter limb lengths, lower fat mass (in males), and lower leg lean mass (in females) may also be indicative of BSI risk. Certain body composition (BComp) and anthropometric measures were predictive of BMD.

Summary: This study explored the impact of economic and social differences among Brazilian states/regions on running participation. The results showed that runners from the South and Southeast regions were most numerous, while runners from the North and Northeast regions were more likely to travel to compete in other states. Factors associated with the OUTrun behavior included preferred distance, SES, and age.

Summary: Reduced bone mineral density of the distal femur (BMDDF) can persist long term after anterior cruciate ligament reconstruction (ACLR), even in athletes who return to high levels of competition. This study evaluated the potential influence of knee extensor peak torque (PT) and rate of torque development (RTD), as well as peak knee flexion (PKF) angle and peak knee extensor moment (PKEM) during running, on longitudinal changes in BMDDF post-ACLR.

Summary: Despite the popularity of running as a sport for children worldwide, there is limited research on its impact on injury and illness, especially for preadolescent and pubescent athletes. Current guidelines on risk factors and suitable running distances for youth runners are opinion based. The International Committee Consensus Work Group aims to evaluate the current science, identify knowledge gaps, categorize risk factors, and provide recommendations for training, nutrition, and participation for youth runners.

Summary: The objective of this study was to identify patterns of clustering of health consequences associated with RED-S among collegiate female Cross-Country runners. The study found a high burden of menstrual disturbance in NCAA D1 cross country runners, and identified three unique presentations of RED-S consequences.
