Summary
Professional bodybuilders experienced improved cognitive performance, specifically faster reaction times, following intense exercise sessions. This suggests that workouts can enhance brain function, even with elevated blood lactate levels.
Area of Science:
- Exercise Physiology
- Cognitive Neuroscience
- Sports Science
Background:
- Elevated blood lactate levels are typically associated with fatigue.
- The cognitive effects of exercise-induced lactacidemia in elite athletes are not fully understood.
- Professional bodybuilders may exhibit different physiological responses to exercise compared to untrained individuals.
Purpose of the Study:
- To investigate cognitive changes in relation to blood lactate levels during intense exercise.
- To assess the impact of a specific CrossFit® workout on cognitive functions in professional bodybuilders.
- To explore potential pro-cognitive effects of acute training sessions.
Main Methods:
- 15 male professional bodybuilders performed CrossFit® Workout 15.5.
- Measurements included blood lactate, blood glucose, reaction time (RT), and cognitive task performance (errors, omissions).
- Data were collected at rest, post-exercise, and after 15 minutes of recovery.
Main Results:
- Bodybuilders presented with slightly elevated basal lactate levels.
- Significant increases in blood lactate (lactacidemia) and decreased RT were observed post-exercise.
- Attentional performance showed improvement in relation to lactacidemia.
Conclusions:
- Bodybuilding regimens contribute to increased basal lactate levels (3.16 mmol/L).
- Acute training sessions can enhance attentional performance, indicating potential pro-cognitive effects.
- Lactacidemia during intense exercise may be linked to improved cognitive function in trained athletes.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

01:19Composition of Polyprotic Acid Solutions as a Function of pH
864
Polyprotic acids of the type H2M constitute two ionizable protons. As a result, on titration with a base, they exhibit two equivalence points in the titration curve. During titration, the species H2M, HM−, and M2− will be present in the solution at different points. The fractions of H2M, HM−, and M2− present at the various instances of the titration are denoted by α0, α1, and α2, respectively.

Amino acids are the monomers that comprise proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, or the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. There are 20 common amino acids present in proteins, each with a different R group. Variation in the amino acid sequence is responsible for...

02:45Functional Groups
88.5K
Functional groups are a group of atoms with characteristic properties, which when linked to the carbon skeleton of a molecule, alter the properties of that molecule. For example, the presence of certain functional groups on a molecule will make them hydrophilic, whereas others will make them hydrophobic. These functional groups are an indispensable part of organic chemistry and important components of biological molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Each...

01:27Language and Cognition
797
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

01:25Cognitive Therapy
1.0K
Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...
