Conceptual physical education: A course for the future.

The conceptual physical education (CPE) innovation began in the mid-20th century as an alternative approach to college-level, activity-only basic instruction classes. In addition to physical activity sessions, CPE courses (classes) use text material and classroom sessions to teach kinesiology concepts and principles of health-related fitness and health-enhancing physical activity. CPE courses are now offered in nearly all college programs as either required or electives classes. Two decades later, the high school CPE innovation began, and Kindergarten-8 programs followed. In this commentary, I argue that historian Roberta Park was correct in her assessment that physical education has the potential to be the renaissance field of the 21st century. Scientific contributions of researchers in kinesiology will lead the way, but science-based CPE and companion fitness education programs that align with physical education content standards and fitness education benchmarks will play a significant role. CPE courses have been shown to be effective in promoting knowledge, attitudes, and out-of-school physical activity and have the potential to elevate physical education as we chart the course of our future.

Luchas y pacificación en la historia de la kinesiologia americana / Struggles and pacification in the history of american kinesiology

En este artículo estudiamos la disputa epistemológica y pedagógica sobre la kinesiología/educación física que ha tenido lugar en las universidades de Estados Unidos desde 1990 hasta la actualidad. Hemos recogido el pensamiento de una muestra amplia de autores involucrados, con el propósito de obtener una visión de conjunto de un proceso que, de acuerdo con Morrow (2006), trata de esclarecer ¿de dónde venimos?, ¿qué somos?, ¿a dónde vamos? Tras el cotejo y análisis de la documentación más relevante concluimos que el periodo 1990-2013, caracterizado por una enconada pugna de paradigmas -en la que han estado implicados humanistas, positivistas, crosdisciplinaristas y subdisciplinaristas-, ha dado como resultado el dominio del paradigma integrador de Kretchmar (2007, 2008) (AU)

In this article we review the epistemological and pedagogical debate on Kinesiology and Physical Education that has been going on in the universities of the US from 1990 to the present. We have compiled the opinions of a wide sample of authors, with the intention of getting the most complete picture of a process that, according to Morrow (2006), seeks to answer the questions "where we come from, who we are, and where we are going". After comparing and analysing the most relevant documents, we conclude that the period 1990-2013, characterized by a bitter struggle between paradigms fought by humanists, positivists, cross-disciplinarists, and sub-disciplinarists, has revealed the eventual predominance of the integrative paradigm of Kretchmar (2007, 2008) (AU)

O uso da maturação somática na identificação morfofucional em jovens jogadores de futebol / The use of somatic maturation in the morphofunctional identification in young soccer players

Objetivo. As modificações que ocorrem com os jovens nas idades anteriores ao pico de velocidade de crescimento (PVC) podem influenciar de maneira direta o seu desempenho nas atividades esportivas. Considerando esse pressuposto, o objetivo deste estudo foi analisar o efeito da maturação somática nas variáveis motoras e corporais de jovens futebolistas. Método. Os 45 sujeitos foram divididos em três grupos de acordo com a maturação somática e submetidos à avaliação antropométrica e a uma bateria de testes que analisaram a flexibilidade (banco de Wells), a potência aeróbia (Yoyo endurance teste, nível 1) e a potência anaeróbia (salto horizontal e vertical). Resultados. Os resultados da análise de variância demonstram que o desempenho no salto vertical com contra movimento (F = 5,10 e p = 0,01) e no salto horizontal (F = 7,19 e p = 0,002) é influenciado pelo nível maturacional, o mesmo ocorrendo para a flexibilidade (F = 6,83 e p = 0,02). Por outro lado, o desempenho no teste de potência aeróbia não foi afetado pelo nível maturacional. As variáveis corporais somatotipo e o recíproco do índice ponderal se mantiveram estáveis independentemente do grau de maturação; apenas foram verificadas diferenças nos valores corporais para o IMC. Conclusão: Assim, pode-se concluir que a determinação dos estágios maturacionais dada pelos anos em relação ao PVC (APVC) dentro de uma determinada faixa etária pode ser um valioso instrumento de orientação para técnicos e treinadores na adequação dos treinamentos em função da real condição funcional de seus jovens atletas(AU)

Objective. The changes in young people at ages preceding the peak height velocity (PHV) can influence their performance in sports. Taken this issue into account, this study aimed to analyze the effect of maturity level on body composition and motor performance in young soccer players. Methods. The 45 subjects were divided into three groups according to somatic maturation and were submitted to anthropometric assessment and to a battery of tests that assessed flexibility (Wells' bench), aerobic power (Yoyo endurance test level 1) and anaerobic power (horizontal and vertical jumps). Results. The results of ANOVA indicate that performance in vertical jump with counter movement (F = 5.10, p = 0.01), standing long jump (F = 7.19, p = 0.002) and flexibility (F = 6.83, p = 0.02) are influenced by the level of maturation status. On the other hand, the performance in the aerobic power test was not affected by maturity status. The somatotype and the reciprocal of ponderal index variables remained steady regardless the degree of maturity; differences were only observed in body mass index values (BMI). Conclusion. Thus, we can conclude that the determination of maturational stages by means of years from PHV can be a valuable tool in order to aid coaches and trainers planning and monitoring training related to the actual functional condition of young athletes(AU)

Internal social processes of discipline formation: the case of kinanthropometry.

In 1972, the term 'kinanthropometry', derived from the Greek words 'kinein' (to move), 'anthropos' (human) and 'metrein' (to measure), was launched in the international, Francophone journal Kinanthropologie by the Canadian William Ross and the Belgians, Marcel Hebbelinck, Bart Van Gheluwe and Marie-Louise Lemmens. The authors defined this neologism as 'the scientific discipline for the study of the size, shape, proportion, scope and composition of the human being and its gross motor functions'. Presenting a theoretical framework for the analysis of the internal social processes of discipline formation - derived from the social history-of-science tradition - this article critically examines whether kinanthropometry was indeed promoted and developed by its community members as a scientific discipline. Therefore, the focus will be on its conceptualisation and positioning within the field of kinanthropology/kinesiology and on its development by a scholarly association, i.e. the International Working Group on Kinanthropometry (IWGK). The strong emphasis of the kinanthropometry community on the standardisation of measurement techniques and its practical and professional application hampered its disciplinary development. Findings of this study could serve as a basis for future 'fundamental' investigations addressing questions of disciplinary development within the field(s) of physical education, kinesiology and sport science(s).

The convergent validity between two objective methods for quantifying training load in young taekwondo athletes.

Various studies used objective heart rate (HR)-based methods to assess training load (TL). The common methods were Banister's Training Impulse (TRIMP; weights the duration using a weighting factor) and Edwards' TL (a summated HR zone score). Both the methods use the direct physiological measure of HR as a fundamental part of the calculation. To eliminate the redundancy of using various methods to quantify the same construct (i.e., TL), we have to verify if these methods are strongly convergent and are interchangeable. Therefore, the aim of this study was to investigate the convergent validity between Banister's TRIMP and Edwards' TL used for the assessment of internal TL. The HRs were recorded and analyzed during 10 training weeks of the preseason period in 10 male Taekwondo (TKD) athletes. The TL was calculated using Banister's TRIMP and Edwards' TL. Pearson product moment correlation coefficient was used to evaluate the convergent validity between the 2 methods for assessing TL. Very large to nearly perfect relationships were found between individual Banister's TRIMP and Edwards' TL (r values from 0.80 to 0.99; p < 0.001). Pooled Banister's TRIMP and pooled Edwards' TL (pooled data n = 284) were nearly largely correlated (r = 0.89; p < 0.05; 95% confidence interval: 0.86-0.91). In conclusion, these findings suggest that these 2 objective methods, measuring a similar construct, are interchangeable.

Integrative training for children and adolescents: techniques and practices for reducing sports-related injuries and enhancing athletic performance.

As more children and adolescents participate in sports and conditioning activities (sometimes without consideration for cumulative workload), it is important to establish age-appropriate training guidelines that may reduce the risk of sports-related injury and enhance athletic performance. The purpose of this article is to review the scientific evidence on youth strength and conditioning and to provide age-appropriate recommendations for integrating different strength and conditioning activities into a well-designed program that is safe, effective, and enjoyable. Integrative training is defined as a program or plan that incorporates general and specific strength and conditioning activities that enhance both health- and skill-related components of physical fitness. The cornerstone of integrative training is age-appropriate education and instruction by qualified professionals who understand the physical and psychosocial uniqueness of children and adolescents.

Physiological, performance, and nutritional profile of the Brazilian Olympic Wushu (kung-fu) team.

The purpose of the present study was to determine physiological, nutritional, and performance profiles of elite Olympic Wushu (kung-fu) athletes. Ten men and four women elite athletes took part in the study. They completed the following tests: body composition, nutritional assessment, upper-body Wingate Test, vertical jump, lumbar isometric strength, and flexibility. Blood lactate was determined at rest and after the Wingate Test. Blood lactate was also determined during a training session (combat and Taolu training). We found low body fat (men: 9.5 +/- 6.3%; women: 18.0 +/- 4.8%), high flexibility (sit-and-reach-men: 45.5 +/- 6.1 cm; women: 44.0 +/- 6.3 cm), high leg power (vertical jump-men: 37.7 +/- 8.4 cm; women: 32.3 +/- 1.1 cm), high lumbar isometric strength (men: 159 +/- 13 cm; women: 94 +/- 6 cm), moderate arm mean and peak power (Wingate Test-men: 4.1 +/- 0.4 and 5.8 +/- 0.5 Wxkg, respectively; women: 2.5 +/- 0.3 and 3.4 +/- 0.3 W.kg, respectively), and elevated blood lactate after the Wingate Test (men: 10.8 +/- 2.0 mmolxL; women: 10.2 +/- 2.0 mmolxL) and during training (combat: 12.0 +/- 1.8 mmolxL; Taolu: 7.7 +/- 3.3 mmolxL). Men athletes consume a high-fat, low-carbohydrate diet, whereas women consume a moderate, high-carbohydrate diet. Energy consumption was markedly variable. In conclusion, Olympic Wushu seems to be a highly anaerobic-dependent combat sport. Low body fat, high flexibility, leg anaerobic power, isometric strength, and moderately high arm anaerobic power seem to be important for successful competitive performance.

Measuring neutrophil functions might be a good predictive marker of overtraining in athletes.

In order to develop a predictive marker of overtraining in athletes, we examined the changes in neutrophil function [reactive oxygen species (ROS) production capability and phagocytic activity (PA)] for 10 male and 13 female judoists attending a training camp. Measurements were taken four times in total--immediately before and after a 2 h unified exercise loading (UEL) performed 1 day before (Pre-Camp) and the day after the 7 day training camp (Post-Camp). UEL-mediated aspartate aminotransferase was higher at Post-Camp than at Pre-Camp in females but not in males. Post-Camp leukocyte/neutrophil counts after the UEL significantly increased in females but not in males. The rate of change in C4 was significantly smaller in females than in males at Post-Camp. Only ROS significantly decreased without any compensation (increase in PA) being made at Post-Camp in females. In conclusion, this finding, namely that ROS significantly decreased only at Post-Camp without any compensatory mechanism (increase in PA), would suggest that the training camp imposed greater loading on females than males. This consideration was supported by the atypical aspartate aminotransferase, leukocyte/neutrophil counts and C4 findings which were seen at Post-Camp only in females. Therefore, regularly examining neutrophil functions such as ROS and PA might be a good preventative measure against overtraining in athletes participating in training camps.

Medico-biological requirements for the chemical composition of specialized products (mixtures) with high content of carbohydrates have been considered. The mixtures are intended for creation of energy reserves and acceleration of restoration processes in persons who were subjected to high physical and neuro-emotional stresses. The chemical composition and fatty-acid content of the high-carbohydrate nutritional mixture are presented.

Biofeedback treatment of genu-recurvatum using an electrogoniometric device with an acoustic signal. One-year follow-up.

The aim was to evaluate the effect of a biofeedback electrogoniometer in the control of recurvation of the knee while walking in patients with neurological diseases. Eighteen patients were trained daily for 12.8 sessions on average with an electrogoniometer attached to the knee, which gave a signal at a threshold value of 180 degrees in order to avoid hypertension of the knee. The improvement was statistically significant even after one year.

Effect of electro-motor stimulation on the power production of a maximally stretched muscle.

UNLABELLED: The effect of electro-motor stimulation (EMS) upon the increase in power production of the tibialis anterior muscle (TA) of healthy individuals in both the maximally stretched (ST group) and shortened (SH group) positions was investigated. The effect of cross-education upon the contralateral muscle was also examined. EMS with a frequency of 50 hertz, a duration of 0.2 miliseconds, and a rectangular wave was applied for ten seconds with a ten-second interval and repeated ten times per day for six weeks. The ST group gained significantly 9.4%, 15.5%, and 16.4% after two, four, and six weeks of stimulation, respectively, while the SH group also showed a significant gain of 5.1%, 8.3%, and 3.0%. When comparing the two groups at the end of the six-week period the ST group's gain was significantly greater. The increase of power production of the unstimulated TA was 5.5%, 8.0%, and 4.3% in the ST group, which was significant at the end of the second and fourth week of stimulation. The SH group, however, registered a non-significant increase of -2.7%, 1.8%, and -1.5%. Comparison between the two groups showed a significant increase in the power production of the unstimulated TA in the ST group commencing the second week. CONCLUSION: EMS of the TA in the maximally stretched position is a more effective way to gain strength.
