Triathlon research shows cycling alters the physiological response of subsequent running but, at present, biomechanical changes are unresolved. This study examined cycling cadence and running stride rate (SR) and length (SL) used by senior elite triathletes during competition. These variables were then compared to running and triathlon performance. Data from 51 elite male World Championships triathletes were analyzed via video recordings and Video Expert II Coach. Triathletes revealed consistent cadences throughout the majority of the cycle (96.8 +2.7 rpm) and run (90.9 +2.4 rpm) disciplines. However, a cadence increase (99.6 +5.7 rpm) was recorded at the completion of the cycle prior to running. Running SR and SL was significantly lower at the end of the run indicating a level of fatigue (p<0.01). Running SL was significantly and positively correlated with running and triathlon performance (p<0.01) suggesting those that could maintain a longer SL had a faster run and better final finishing position.

Purpose Of Review: This review aims to assess the current landscape of animal models used in myocarditis research, with a focus on understanding their utility in uncovering the pathophysiology of the disease. The goal is to evaluate these models' strengths and weaknesses and propose optimizations to make them more relevant and reliable for both mechanistic studies and therapeutic interventions in myocarditis.
Recent Findings: Recent studies have primarily utilized animal models, particularly viral and autoimmune myocarditis models, to study disease mechanisms.

Osteosarcoma stands as the predominant bone malignancy afflicting children and young adults. Despite strides in treatment, the enduring reality is that the long-term survival rates for patients grappling with recurrences and metastases linger at a mere 30%. This underscores the pressing demand for novel prognostic markers and therapeutic avenues to improve outcomes and offer hope to those battling this formidable disease.

Background: There is limited research comparing both performance and brain control of walking between older adults with progressive and relapsing-remitting MS.
Objective: This study compared older adults with progressive and relapsing-remitting MS for differences in prefrontal cortex (PFC) activation in single- and dual-task-walking and practice-related effects on neural efficiency, walking, and cognitive performances.
Methods: Older adults with progressive (n = 32, age=65±6ys) and relapsing-remitting (n = 63, age=65±4ys) MS completed three conditions (single-task walk, single-task-alpha, i.
