Intercellular adhesion molecule-1 (ICAM-1) acts as the main factor in the occurrence of atherosclerosis and inflammatory diseases. This study aimed to investigate the response of ICAM-1to exhaustive submaximal exercise and its correlation with maximal oxygen consumption (VO2max), body mass index (BMI), waist-hip ratio (WHR), body fat percentage (BF %) and calories burned during exercise (CB) in healthy men. Thirteen healthy men (mean ± standard deviation: age 23 ± 3 years, weight 78 ± 4 kg, height 180 ± 4 cm) cooperated in this quasi-experimental study and performed a single bout of exhaustive submaximal exercise on a cycle ergometer. Blood samples were collected from the antecubital vein before and immediately after exercise. Data were analyzed using the paired sample t-test and Pearson's correlation coefficient (α=0.05). Exhaustive submaximal exercisehad no significant effect on serum sICAM-1. Also, there were no significant correlations between ICAM-1 induced by the exhaustive submaximal exercise and VO2max, BMI, WHR, BF % and CB. According to our findings, it cannot be ruled out that exhaustive submaximal exercise results in pathological and inflammatory conditions in healthy men. In Also, anthropometric and physiological parameters do not affect the response of ICAM-1 to exercise in healthy men.

Background/objectives: Low energy availability (LEA) can cause impaired reproductive function, bone health issues, and suppressed immune function, and may result in decreased performance and overall health status. The purpose of this study was to investigate adaptions of body composition, blood status, resting metabolic rate, and endurance performance to gain more comprehensive insights into the symptoms of LEA and the adaptive effects in the athlete population (active women (n = 11) and men (n = 11)).
Methods: Three treatments were defined as 45 (EA45, control), 30 (EA30), and 10 (EA10) kcal/kg FFM/day and randomly assigned.

Nitric oxide (NO) is a ubiquitous signaling molecule known to modulate various physiological processes, with specific implications in skeletal muscle and broader applications in exercise performance. This review focuses on the modulation of skeletal muscle function, mitochondrial adaptation and function, redox state by NO, and the effect of nitrate supplementation on exercise performance. In skeletal muscle function, NO is believed to increase the maximal shortening velocity and peak power output of muscle fibers.

Background: Despite the wide use of compression garments to enhance athletic running performance, evidence supporting improvements has not been conclusive. This updated systematic review and meta-analysis of randomized controlled trials (RCTs) compared the effects of compression garment wearing with those of non-compression garment wearing (controls) during running on improving running performance.
Methods: A comprehensive search was conducted in the electronic databases (Web of Science, EBSCOhost, PubMed, Embase, Scopus, and Cochrane) for RCTs comparing running performance between runners wearing compression garments and controls during running, from inception to September 2024.

Background: In patients with COPD, preventive treatment with acetazolamide reduces adverse health effects during altitude travel. We investigated whether preventive acetazolamide treatment modifies exercise performance in COPD patients going to high altitude.
Methods: In this randomised, double-blind trial, lowlanders with COPD, forced expiratory volume in 1 s (FEV) 40-80% predicted, were assigned to acetazolamide (375 mg per 24 h) or placebo treatment starting 24 h before ascent and while staying at 3100 m.

Purpose: Cigarette smoking (CS) induces systemic changes that impair cardiorespiratory and muscular function both at rest and during exercise. Although these abnormalities are reported in sedentary, middle-aged smokers (SM) with pulmonary disease, few and controversial studies focused on young, physically active SM at the early stage of smoking history. This study aimed at assessing the impact CS on cardiorespiratory and metabolic response during an incremental test and the subsequent recovery in young, physically active SM without known lung or cardiovascular disease.
