Summary
The ice hockey-specific complex test (IHCT) demonstrates good intra-rater reliability for assessing player performance. Load parameters showed higher reliability than stress parameters, making IHCT a valuable tool for training evaluation.
Area of Science:
- Sports Science
- Performance Analysis
- Ice Hockey Training
Background:
- Ice hockey demands intense, multidirectional, and intermittent physical efforts.
- Assessing player performance requires sport-specific testing protocols.
Purpose of the Study:
- To evaluate the intra-rater reliability of the ice hockey-specific complex test (IHCT).
- To determine the test's suitability for analyzing performance under competitive conditions.
Main Methods:
- Twenty professional ice hockey players performed the IHCT twice over two days.
- The test included sprints, transitions with/without a puck, and shots.
- Lactate concentrations and heart rates were measured as stress parameters.
Main Results:
- Intra-rater reliability (ICC) for load parameters ranged from 0.54 to 0.98, with 82% exceeding 0.75.
- Intra-rater reliability (ICC) for stress parameters ranged from 0.26 to 0.87.
- Coefficient of Variation (CV) was lower for load parameters (mean 4.7%) compared to stress parameters (mean 13.4%).
Conclusions:
- The IHCT is a reliable and valid tool for assessing ice hockey performance.
- It simulates competitive conditions, aiding in performance analysis and training intervention evaluation.
- Coaches and sports scientists can utilize the IHCT to monitor player development.

14.0K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.

The real number system cannot represent the square root of a negative number, which restricts solutions for certain equations, such as quadratics with negative discriminants. To address this, the complex number system was developed, introducing the imaginary unit i, where i = √(-1). This extension allows for the representation of all roots, including those involving negative radicands.A complex number is written in the form x + yi, where x and y are real numbers. Here, x represents the...
