Effects of L-Glutamine on muscular damage
This study investigated whether oral L-glutamine supplementation could attenuate exercise-induced muscle damage (EIMD) in professional basketball players during a high-intensity competition period. Using a double-blind, placebo-controlled crossover design, 12 participants received either 6 g/day of glutamine or a placebo for 20 days. The results showed that the glutamine-supplemented group had significantly lower blood levels of muscle damage markers, including creatine kinase (CK), myoglobin (Mb), and aspartate transaminase (AST), compared to the placebo group. Furthermore, glutamine intake was associated with lower levels of adrenocorticotropic hormone (ACTH), helping to maintain a better balance between catabolic and anabolic hormones. The researchers concluded that glutamine supplementation is a practical strategy for improving recovery in sports characterized by eccentric actions.
Patterns of exercise-related inflammatory response in sickle cell trait carriers
This study investigated the effects of strenuous exercise on individuals with Sickle Cell Trait (SCT), finding that intense physical activity triggers a unique inflammatory and cellular response compared to those with normal hemoglobin. These findings underscore the specific physiological demands placed on SCT carriers during exercise and highlight the importance of supporting the body's cellular health to manage exercise-induced stress.
Blood rheology abnormalities and vascular cell adhesion mechanisms in sickle cell trait carriers during exercise
This scientific review explains how strenuous exercise can lead to significant changes in blood properties for individuals with Sickle Cell Trait, including an increase in red blood cell rigidity. These findings highlight the unique physiological stress that exercise places on the circulatory system of SCT carriers, underscoring the importance of nutritional support focused on maintaining healthy red blood cell function.
