Summary
This bibliometric analysis reveals a growing body of research on exercise-induced muscle damage (EIMD) and protein intake. Key topics include exercise modes, nutrition, and recovery, with future research focusing on novel strategies and underlying mechanisms.
Area of Science:
- Sport Science
- Physiology
- Nutrition
- Biochemistry & Molecular Biology
Background:
- Extensive research exists on exercise-induced muscle damage (EIMD), covering nutrition and recovery.
- However, comprehensive bibliometric analyses of EIMD and protein intake research are lacking.
Purpose of the Study:
- To conduct a bibliometric and visual analysis of scientific output and research activity on EIMD and protein intake.
- To identify key research trends, collaborations, and future directions in this field.
Main Methods:
- Bibliometric and visual analysis of 351 publications from 1975-2022 retrieved from Web of Science Core Collection.
- Quantitative and qualitative data collection including citations, H-indexes, co-authorship, co-citation, and keyword co-occurrence.
Main Results:
- A steady increase in annual publications on EIMD and protein intake.
- The United States leads in publications, with limited transnational institutional cooperation.
- Research is concentrated in high-impact journals across Sport Science, Physiology, Nutrition, and Biochemistry & Molecular Biology.
Conclusions:
- EIMD and protein intake research is expanding, with core themes in exercise modes, nutritional strategies, beneficial outcomes, and proposed mechanisms.
- Future research should explore novel exercise/training models, nutritional strategies, recovery techniques, hormesis for hypertrophy, and underlying damage mechanisms.

01:24Muscle Recovery and Fatigue
2.3K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

01:21Overview of Protein Metabolism
1.6K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

01:27Exercise and Muscle Performance
1.5K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

1.0K
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

01:28Proteins: Dietary Sources and Requirements
566
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...
