Evidence-based classification systems in Paralympic sport require knowledge of the underlying effect of impairment in a specific sport. This study investigated the relationship between cognition and tactical proficiency in 88 well-trained table tennis players with intellectual disability (ID; 29 women, 59 men, M ± SD IQ 59.9 ± 9.6). Data were collected at 3 competitions sanctioned by the International Federation for Para-Athletes with Intellectual Disabilities (INAS). A generic cognitive test consisting of 8 neuropsychological subtests was used to assess cognitive abilities relevant to sport (reaction time, processing speed, and decision speed; spatial visualization; fluid reasoning; memory; executive functioning; and visual processing). The backward stepwise-regression analysis model revealed that 18% of the variance in tactical proficiency was attributed to spatial visualization and simple reaction time. Applications of these findings resulted in an evidence-based classification system that led to the reinclusion of athletes with ID in Paralympic table tennis and provide the basis for future research in this important area.

To quantify the activity profiles of elite wheelchair rugby (WCR) players and establish classification-specific arbitrary speed zones. In addition, indicators of fatigue during full matches were explored.
Seventy-five elite WCR players from 11 national teams were monitored using a radio-frequency-based, indoor tracking system across 2 international tournaments. Players who participated in complete quarters (n = 75) and full matches (n = 25) were included and grouped by their International Wheelchair Rugby Federation functional classification: groups I (0.5), II (1.0–1.5), III (2.0–2.5), and IV (3.0–3.5).
During a typical quarter, significant increases in total distance (m), relative distance (m/min), and mean speed (m/s) were associated with an increase in classification group (P < .001), with the exception of groups III and IV. However, group IV players achieved significantly higher peak speeds (3.82 ± 0.31 m/s) than groups I (2.99 ± 0.28 m/s), II (3.44 ± 0.26 m/s), and III (3.67 ± 0.32 m/s). Groups I and II differed significantly in match intensity during very-low/low-speed zones and the number of high-intensity activities in comparison with groups III and IV (P < .001). Full-match analysis revealed that activity profiles did not differ significantly between quarters.
Notable differences in the volume of activity were displayed across the functional classification groups. However, the specific on-court requirements of defensive (I and II) and offensive (III and IV) match roles appeared to influence the intensity of match activities, and consequently training prescription should be structured accordingly.

The aim was to analyze the relationship between performance and classes of swimmers and between types of physical impairments and medal winners. Participants were 374 swimmers at the 1996 Paralympic Games with six types of impairments: poliomyelitis, cerebral palsy, spinal cord injury, amputation, dysmelia, and les autres. Data included performance times, gender, classification, swimming stroke and distance, and type of impairment. ANOVA and Spearman rank correlation treatment of data revealed significant differences in swimmers’ mean speeds across classes and positive correlations in swimmers’ classes and swimming speeds in all male and female events; no type of impairment dominated the opportunity to participate, win medals, or advance to the finals. It was concluded that the current swimming classification system is effective with respect to generating fair competition for most swimmers.

In recent years the International Paralympic Committee (IPC), the institution responsible for the administration, organization, and management of the Paralympic Games, has reshaped the landscape of sport for the disabled. This article argues that the IPC has marginalized the practice community, notably the International Organizations of Sport for the Disabled. By wrestling away control of the classification systems developed by these organizations, the IPC has transformed them to such an extent that they fail to provide opportunities for equitable sporting practice and the result has been a threat to the ideology of Paralympism. We illustrate this by examining two classification systems that are currently used within Paralympic Sport: the integrated functional system employed in the sport of swimming and the disability-specific system used within athletics.

. 19 These different terminologies and measurement types do not facilitate a standardized classification. Specifically in older adults, several have shown that the amount of PA performed is not the most accurate method for defining the physical condition of older people and, accordingly, their ability

The purpose was to develop an index of walking performance and to examine gait pattern classifications of children with developmental coordination disorder (DCD). The San Diego database (Sutherland, Olshen, Biden, & Wyatt, 1988) provided data for our calculation of the index and for determining that the index was able to differentiate between gait variables of older (ages 3 to 7) and younger (ages 1 to 2.5) children comprising the database. We obtained cinematographical data on 17 biomechanical markers of 6 boys and 1 girl, ages 6 to 7, with DCD, during walking. Analysis of individuals with DCD gait patterns revealed that most had abnormal walking patterns. The means of the time/distance gait variables did not differ between children with DCD and San Diego children, ages 3 to 7. Children with DCD had much larger variances than other children, indicating no systematic pattern in individual gait differences.
Classification of Instructional Programs (CIP) codes were designed to report outcomes in higher education by specific disciplines and professions, however, universities, states, and accreditation bodies also use these codes in other ways. This paper describes CIP-2010 usage in higher education and how these codes are used in funding public universities in Texas, and summarizes the American Kinesiology Association/National Academy of Kinesiology recommendations to the National Center for Education Statistics on updating kinesiology-related CIP codes. Kinesiology leaders should be knowledgeable about how CIP codes are often used behind the scenes in a variety of ways that affect our faculty, programs, and the field. Greater use of the term kinesiology in many future CIP codes would benefit the field and individual departments seeking alignment with institutional priorities.

In response to the absence of a taxononomical system for the structured assessment, conceptualization, and intervention of athlete-clients, the MCS-SP is a model for the comprehensive evaluation of athlete-clients’ needs, strategies for in-depth case conceptualization, and systematic formulation of the most appropriate type and level of professional service required. This classification system is based on the primary issues, needs, and life circumstances of the athlete-client and the suggested assessment and intervention foci combine the environmental, interpersonal, intrapersonal, behavioral, and performance history/demands that impact athletic clientele. Categories within the taxonomy include Performance Development, Performance Dysfunction, Performance Impairment, and Performance Termination, each of which include two subtypes that further guide the appropriate, ethical, and effective provision of services.

To quantify the influence of the assistive pole, seat configuration, and upper-body and trunk strength on seated-throwing performance in athletes with a spinal-cord injury (SCI).
Ten Paralympic athletes competing in wheelchair rugby, basketball, or athletics (seated throws) participated in 2 randomized sessions: seated throwing and strength tests. Participants threw a club from a custom-built throwing chair, with and without a pole. 3D kinematic data were collected (150 Hz) for both conditions using standardized and self-selected seat configurations. Dominant and nondominant grip strength were measured using a dynamometer, and upper-body and trunk strength were measured using isometric contractions against a load cell.
Seated throwing with an assistive pole resulted in significantly higher hand speed at release than throwing without a pole (pole = 6.0 ± 1.5 m/s, no pole = 5.3 ± 1.5 m/s; P = .02). There was no significant difference in hand speed at release between standardized and self-selected seating configurations during seated throwing with or without an assistive pole. Grip strength (r = .59–.77), push/pull synergy (r = .81–.84), and trunk-flexion (r = .50–.58) strength measures showed large and significant correlations with hand speed at release during seated throwing with and without an assistive pole.
This study has demonstrated the importance of the pole for SCI athletes in seated throwing and defined the relationship between strength and seated-throwing performance, allowing us to better understand the activity of seated throws and provide measures for assessing strength that may be valid for evidence-based classification.

Development of a unified classification system to replace four of the systems currently used in disability athletics (i.e., track and field) has been widely advocated. The definition and purpose of classification, underpinned by taxonomic principles and collectively endorsed by relevant disability sport organizations, have not been developed but are required for successful implementation of a unified system. It is posited that the International classification of functioning, disability, and health (ICF), published by the World Health Organization (2001), and current disability athletics systems are, fundamentally, classifications of the functioning and disability associated with health conditions and are highly interrelated. A rationale for basing a unified disability athletics system on ICF is established. Following taxonomic analysis of the current systems, the definition and purpose of a unified disability athletics classification are proposed and discussed. The proposed taxonomic framework and definitions have implications for other disability sport classification systems.
