The favorable effects of physical activity on the cardiovascular system have been well described in scientific literature. Physical activity reduces cardiovascular morbidity and mortality in both healthy subjects and in patients with cardiovascular disease. However, different intensity levels of physical activity have a different impact on the cardiovascular system. Some data support the hypothesis of a "physical activity paradox": repetitive exposure to vigorous physical activity may induce biological effects that counteract the benefits of moderate intensity levels of physical activity. In this review, we report the main effects of acute and chronic physical activity on the cardiovascular system and we summarize the biochemical mechanisms that may explain these effects.

Objective: This study aims to explore the impact of physical exercise on feelings of inferiority among college students, focusing on the mediating roles of social support and emotional regulation ability. The research investigates both direct and indirect pathways to understand how physical exercise enhances psychological resilience and mitigates negative self-perceptions.
Methods: A sample of 2,036 college students from 15 provinces in China was surveyed using validated scales for physical exercise, feelings of inferiority, social support, and emotional regulation ability.
Arthroscopic-Assisted Posterolateral Corner Reconstruction of the Knee: Novel Technique, Classification, Surgical Algorithm, and Midterm Results.
Arch Bone Jt Surg

Department of Epidemiology, School of Public Health, Iran University of Medical Sciences, Tehran, Iran.
Objectives: This study aimed to introduce a new arthroscopic method for reconstructing the popliteus tendon (PT). This minimally invasive technique is performed through the posterolateral corner (PLC) of the knee, which can reconstruct the posterolateral rotary instability (PLRI) of the knee.
Methods: Thirty-nine patients (8 females, 31 males) with PLC injury and normal knee alignment underwent arthroscopic PT reconstruction.
Purpose: This study aimed to validate the accuracy of the Active Style Pro HJA-750C (ASP) in measuring metabolic equivalents (METs) during walking and reaching tasks in individuals with subacute stroke using a respiratory gas analyzer as a reference.
Methods: Twenty-three hospitalized patients with subacute stroke participated in this study. They performed sitting and standing reaching tasks, as well as walking while wearing a VO2 Master respiratory gas analyzer and ASP devices on both the paretic and non-paretic sides.
