“…Our goal with asking in this way was to detect safety concerns directly related to the karate classes. Karate training in older non-PD cohorts has improved motor reactivity, stress tolerance, and gait, even under dual-task conditions [36,37]. In the current study, karate instructors enhanced the class curriculum with PD-focused training on how to fall safely and how to return to standing.…”

Background Multiple exercise modalities and mindfulness activities are beneficial in Parkinson's Disease (PD). Karate is a martial art that combines aerobic and large-amplitude movements, balance and core training, and mindfulness, suggesting a potential benefit for individuals with PD from multiple perspectives. Objective To evaluate the feasibility of community-based Shotokan karate classes involving physical activity and mindfulness among individuals with mild-to moderate-stage PD, and to explore the effects of karate on objective and patient-reported outcomes. Methods We conducted a 10-week, unblinded trial of twice weekly, PD-specific karate classes. Feasibility was assessed by: dropout rates, adherence via attendance records, adverse effects and falls, and continued participation six months post-intervention. Participants completed pre-and post-intervention assessments of disease-related quality of life (Parkinson's Disease Questionnaire-8, PDQ-8), falls, and post-intervention assessment of change in overall wellbeing (Patient Global Impression of Change, PGIC), with exploratory measures of mobility using the Timed Up and Go (TUG), mood using the Hospital Anxiety and Depression Scale (HADS), and cognition using digit span forward and backward and the Symbol Digit Modalities Test (SDMT).

“…This is mostly within the scope of interest of biomechanics, sport, medicine and rehabilitation. Human movements can be analyzed by various methods, for example by kinetic modeling [ 1 , 2 , 3 ], kinematic [ 3 , 4 , 5 , 6 , 7 , 8 ], electromyography [ 4 , 6 , 9 , 10 , 11 ], gait and posture analysis [ 12 ] and pattern recognition [ 13 ]. Quite often, those evaluations require statistical analysis of data from several measurements of the same action.…”

The aim of this paper is to propose and evaluate the novel method of template generation, matching, comparing and visualization applied to motion capture (kinematic) analysis. To evaluate our approach, we have used motion capture recordings (MoCap) of two highly-skilled black belt karate athletes consisting of 560 recordings of various karate techniques acquired with wearable sensors. We have evaluated the quality of generated templates; we have validated the matching algorithm that calculates similarities and differences between various MoCap data; and we have examined visualizations of important differences and similarities between MoCap data. We have concluded that our algorithms works the best when we are dealing with relatively short (2–4 s) actions that might be averaged and aligned with the dynamic time warping framework. In practice, the methodology is designed to optimize the performance of some full body techniques performed in various sport disciplines, for example combat sports and martial arts. We can also use this approach to generate templates or to compare the correct performance of techniques between various top sportsmen in order to generate a knowledge base of reference MoCap videos. The motion template generated by our method can be used for action recognition purposes. We have used the DTW classifier with angle-based features to classify various karate kicks. We have performed leave-one-out action recognition for the Shorin-ryu and Oyama karate master separately. In this case, 100% actions were correctly classified. In another experiment, we used templates generated from Oyama master recordings to classify Shorin-ryu master recordings and vice versa. In this experiment, the overall recognition rate was 94.2%, which is a very good result for this type of complex action.

“…Dessa maneira, modalidades como o Karatê e a Ginástica Generalizada, que abrangem diversificadas respostas comportamentais diante de situações de equilíbrio estático e dinâmico, caracterizadas por perturbar constantemente o sistema de controle postural, ainda são pouco exploradas. Alguns autores [21][22][23][24] discutem o efeito positivo do treinamento do Karatê, como prática de habilidades motoras que podem influenciar de maneira positiva, em respostas de ações motoras mais rápidas para o controle postural. Benefícios são a melhoria na aptidão, agilidade, concentração, autocontrole e mobilização, além de evidências de melhoras das funções cognitivas 22,24 .…”

O objetivo deste estudo foi comparar o equilíbrio postural de idosos praticantes de duas modalidades de exercícios físicos, idosos não praticantes e adultos jovens, na presença e ausência de informação visual. Participaram 51 indivíduos (n = 31 do sexo feminino e n = 20 do sexo masculino), subdivididos em quatro grupos: idosos praticantes de karatê (GIKA, n = 11), idosos praticantes de ginástica generalizada (GIGG, n = 16), idosos não praticantes de exercícios físicos (GINP, n = 12), e um grupo controle de adultos jovens (GAJ, n = 12). A tarefa constituiu em permanecer em apoio estático, posição semi tandem, sobre a plataforma de força por 40 segundos. Duas condições experimentais foram realizadas: com visão e sem visão. As variáveis de controle postural obtidas a partir do centro de pressão (Cop) foram: área de oscilação do Cop, velocidade e amplitude média de oscilação do Cop nas direções ântero-posterior e médio-lateral. Os resultados indicaram que os idosos praticantes de exercícios físicos GIKA e GIGG obtiveram desempenhos semelhantes, não diferenciando a modalidade praticada, tanto na condição com visão quanto sem visão, aproximando seu desempenho de adultos jovens, mais especificamente o grupo GIGG. Na condição sem visão, todos os grupos mostraram-se mais suscetíveis à instabilidade postural. O grupo GINP apresentou maior oscilação postural em todas as variáveis analisadas quando comparado aos outros grupos, apresentando maiores diferenças com o grupo GIGG e GAJ. Sendo assim, os grupos de idosos praticantes não se diferenciaram, se aproximando ao desempenho dos adultos jovens. Compreende-se que a prática de exercícios físicos tem papel importante e eficaz na manutenção do equilíbrio postural durante o envelhecimento e pode evitar possíveis quedas.

Changes in dual-task performance after 5 months of karate and fitness training for older adults to enhance fall prevention

Abstract: An improvement of the human walk seems to be possible through karate and fitness training, even under dual-task conditions. A prolonged intervention time with multiple repetitions of gait analysis could give better evidence if karate is a useful tool to increase fall prevention.
