Cumulative Training Dose's Effects on Interrelationships Between Common Training-Load Models During Basketball
Summary
Training load (TL) responses in basketball vary with cumulative training dose. Different methods show limited agreement beyond 20 minutes, indicating dose-dependent interchangeability of internal and external TL measures.
Area of Science:
- Sports Science
- Exercise Physiology
- Basketball Performance Analysis
Background:
- Understanding training load (TL) responses in basketball is crucial for athlete development.
- Limited research exists on how cumulative training dose influences TL and their interrelationships in basketball.
Purpose of the Study:
- To examine temporal changes in training load responses during basketball activity.
- To investigate the influence of cumulative training dose on training load responses.
- To analyze interrelationships between various internal and external training load metrics.
Main Methods:
- Ten junior male basketball players performed 4x10-min simulated basketball bouts.
- Internal TL was measured using session rating of perceived exertion (sRPE), summated heart-rate zones (SHRZ), and training impulse (TRIMP) models (Banister and Lucia).
- External TL was assessed via mean sprint and circuit speeds, with correlational analyses across cumulative doses (0-40 min).
Main Results:
- Session rating of perceived exertion (sRPE) TL increased after the first 10-min bout.
- sRPE TL correlated with Lucia TRIMP up to 20 min; sprint and circuit speeds correlated up to 20 min.
- Summated heart-rate zones (SHRZ) and Banister TRIMP showed significant correlations across all training doses.
Conclusions:
- Common training load (TL) approaches show limited convergence in basketball beyond 20 minutes.
- The interchangeability of internal and external TL measures is dose-dependent in basketball.
- Psychophysiological factors likely influence temporal changes in training load responses.

Drug response models describe how pharmacological agents interact with biological systems to produce measurable effects. Baseline responses are inherent physiological activities without a drug significantly influencing the observed pharmacological outcomes. Depending on the drug response model employed, these baseline responses may combine with the drug's effect in either an additive or proportional manner.Additive Drug Response ModelIn the additive model, the drug effect is independent of the...

Calculating drug dosage and accumulation in multiple-dose regimens is crucial for achieving therapeutic efficacy while avoiding toxicity. This involves determining the plasma drug concentrations over time to optimize dosing schedules. The principle of superposition is fundamental in this process, allowing for the prediction of drug concentration in plasma following multiple doses based on single-dose data.The principle of superposition asserts that the plasma concentration-time curves from...

Pharmacodynamics explores the relationship between drug concentration and its effect. In a quantal response drug, the duration of action better correlates with drug concentration, while for graded effect drugs, the intensity of response is more relevant. This intensity depends on the dose, drug removal rate, and the region of the concentration–response curve.The concentration–response curve can be divided into three regions. Region 3 (80–100% maximum response) demonstrates...

A loading dose is an essential pharmacological strategy to rapidly achieve the target plasma drug concentration necessary for an immediate therapeutic effect. This approach is especially critical for drugs characterized by slow absorption or extended half-lives, where delaying therapeutic plasma levels could compromise treatment outcomes. By administering a loading dose, clinicians ensure a prompt onset of drug action, even for agents with complex pharmacokinetic profiles.Achieving steady-state...

01:03Dose-Response Relationship: Overview
5.7K
Agonists can bind with and activate receptors, resulting in the formation of drug-receptor complexes. Once formed, these complexes catalyze many biochemical processes at the cellular level and subsequently induce a pharmacologic response. The degree of response is directly proportional to the fraction of activated receptors, which in turn, depends on the concentration of the drug at the receptor site as well as the sensitivity of the receptor. An increase in the administered dose contributes to...

01:21Dose Response Curve: Conventional Versus Nonmonotonic
219
The correlation between a drug's dosage and its impact on a biological system is a cornerstone of pharmacology and toxicology. Conventional dose–response curves, which include graded and quantal relationships, are key to this understanding. Graded dose–response curves depict the spectrum of a biological reaction to different doses within an individual, indicating that as the drug dosage increases, so does the intensity of the response. On the other hand, quantal dose–response...
