Aging leads to a general decline in body functions that affects quality of life. Muscle function beginsto slow the contraction from the 40 to 50 years and decreases muscle strength 1 to 1.5% per yearafter 60 years (Booth, Weeden,andTseng, 1994; Vandervoort, 2002; VandervoortandMccomas, 1986).Older adults do less work for lower fast angular velocities (Power, et al., 2014), and less power forslow, moderate and fast angular velocities (Dalton, Power, Vandervoort,andRice, 2012), than youngadults. These losses increase as age increases. One factor that exacerbates these functional losses isthe sedentary lifestyle, however, the physical exercise appears as an inversion factor, which cannotonly reverse this decline but also promote an increase in functional capacity at the neuromuscularlevel. The athletic performance is seen as diminished in older adults, but in the case of martial arts,the karate Sensei’s are the technical execution model. This leads us to question if in karate youngadults have better performance than older adults? Which in many cases are their Senseis’s. The aimof this study was to analyze the effects of the aging process in the kinematic and temporal structureof the frontal kick on veteran active karate practitioners.
