AI Article Synopsis
- The study investigates the reliability and validity of the 6-min run test for measuring cardiorespiratory fitness in young adults with Down syndrome.
- High reliability was found for both the distances covered in the test and peak heart rate measures across two testing sessions.
- There is a significant correlation between the 6-min run test and the 16-min shuttle run test, indicating that the 6-min test is a valid measure of fitness in this population.
Article Abstract
Background: There is limited evidence about the psychometric properties of field tests to measure cardiorespiratory fitness in people with Down syndrome.
Objective: This study aimed at analyzing the reliability and convergent validity of the 6-min run test when performed by young adults with Down syndrome (DS).
Methods: In a cross-sectional design fifty-one young adults with DS (mean age 26.20 ± 7.14 years; 54% women) performed the 6-min run test and the 16-min shuttle run test twice with a one week-interval between test and retest.
Results: The 6-min run test offered high reliability for the distances covered (ICC: 0.974; 95% CI: 0.955-0.985) and good reliability when comparing peak heart rate values obtained in the test and retest (ICC: 0.870; 95% CI: 0.772-0.926). A significant correlation between the 6-min run test and the 16-min shuttle run test was observed for the test (r = 0.705; Sig = 0.001), and retest phases (r = 0.651; Sig = 0.001). The relationship between the estimated maximal oxygen consumption (VO max) peak after the performance of the 16-min shuttle run test and the distance covered by the 6-min run test was statistically significant (r > 0.7). No significant differences were found between the equations that estimate VO peak for both tests.
Conclusions: These findings suggest that the 6-min run test shows high test/retest reliability and moderate to moderately high convergent validity when performed by adults with DS.

Exercise to treat traumatic brain injury (TBI) is a novel approach that has only become recognized in the past decade. High-intensity gait training (HIGT) has been studied in subjects following stroke; however, little research investigates similar protocols on patients with TBI. The study evaluated HIGT as an intervention for enhancing patient recovery after TBI.

Aims: To clarify the long-term effects of short-term exercise instructions by physical therapists in Japanese people with type 2 diabetes (T2D).
Methods: This was a follow-up study of 2 years after randomized controlled study of short-term exercise instructions included 18 patients (5 in the non-intervention and 13 in the intervention groups). Motor skills, including 6 min walk test scores, and transtheoretical model was evaluated at baseline (week 0) the end of the study of the previous study (week 8), and 2 years after (2 years).
Validation of new predictors of mortality and BODE index variants in patients with COPD at moderate altitude.

Department of Smoking and COPD Research, National Institute of Respiratory Diseases, Mexico City, Mexico.
Background: COPD ranks as the third leading global cause of mortality. Despite the widespread use of the BODE index and its variants for mortality prediction, their accuracy may be affected by factors like ethnicity, altitude and regional disparities. This study aimed to assess a new altitude-adapted prognostic index in COPD patients at moderate altitudes compared with the BODE and other mortality predictors.

Background: Endothelial function (EndFx) is a core component of cardiovascular (CV) health and cardioprotection following acute myocardial infarction (AMI) treated with primary percutaneous coronary intervention (PCI).
Hypothesis: AMI patients experience endothelial dysfunction (EndDys), associated with traditional CV risk factors and sleep patterns. EndFx may also predict short and mid-term outcomes.
Continuous risk monitoring and management of heart failure: Rationale and design of the ALLEVIATE-HF trial.
Eur J Heart Fail
January 2025
Medical University of South Carolina, Charleston, SC, USA.
Aims: Early identification and management of worsening heart failure (HF) is necessary to prevent disease progression and hospitalizations. The ALLEVIATE-HF (Algorithm Using LINQ Sensors for Evaluation and Treatment of Heart Failure) trial is a prospective, randomized, controlled, double-blind, multicentre trial that aims to assess the safety and efficacy of using the Reveal LINQ™ insertable cardiac monitor (ICM) in patients with HF to continuously monitor and evaluate HF risk status and guide timely interventions.
Methods: The ICM algorithm uses parameters derived from electrocardiogram (atrial fibrillation [AF], ventricular rate during AF, heart rate variability, and night heart rate), three-axis accelerometer (patient activity duration), and subcutaneous bioimpedance (fluid volume, respiration rate).
