A New Technique

AbstractThis study has been inspired by golf ball movements during the game to improve particle swarm optimization. Because, all movements from the first to the last move of the golf ball are the moves made by the player to win the game. Winning this game is also a result of successful implementation of the desired moves. Therefore, the movements of the golf ball are also an optimization, and this has a meaning in the scientific world. In this sense, the movements of the particles in the PSO algorithm have been associated with the movements of the golf ball in the game. Thus, the velocities of the particles have converted to parabolically descending structure as they approach the target. Based on this feature, this meta-heuristic technique is called RDV (random descending velocity) IW PSO. In this way, the result obtained is improved thousands of times with very small movements. For the application of the proposed new technique, the inverse kinematics calculation of the 7-joint robot arm has been performed and the obtained results have been compared with the traditional PSO, some IW techniques, artificial bee colony, firefly algorithm and quantum PSO.

Las adherencias en ciertas zonas musculares generan tensiones en otras musculaturas de la misma cadena muscular. El objetivo del estudio es probar el efecto inmediato de la “Auto-liberación Miofascial” (SMR) con la técnica de pelota de golf en la fascia plantar en deportistas federados de “Fútbol 11” (FU) y “Fútbol Sala” (FS) y su incidencia sobre la musculatura isquiosural. Además, se analizó las diferencias entre cada modalidad. El diseño es de tipo experimental longitudinal, con una muestra de 20 deportistas federados. Los resultados muestran una mejora en la longitud alcanzada en el “Test Sit and Reach” (SRT) de forma significativa la SMR entre “Grupo Control” (GC) y “Grupo Experimental” (GE). Entre modalidades no se aprecian diferencias significativas. Se concluye que existe un efecto inmediato de la SMR con la técnica de pelota de golf en la fascia plantar sobre la musculatura isquiosural. No existiendo diferencias significativas entre modalidades. Adhesions in certain muscle areas generate tension in other muscles of the same muscle chain. The aim of the study is to test the immediate effect of the “Self-myofascial release” (SMR) with the golf ball technique on the plantar fascia in federated sportsmen of "Football 11" (FU) and "Futsal" (FS) and its influence on hamstring musculature. Besides, the differences between each modality have been analysed. The design is of the longitudinal experimental type, with a sample of 20 federated sportsmen. The results show significant improvement in the length reached in the “Sit and Reach Test” (SRT) after the SMR between "Control Group" (GC) and "Experimental Group"(GE). There are no significant differences between modalities. It is therefore concluded that there is an immediate effect of SMR with the golf ball technique on the plantar fascia over the hamstring muscle. There are no significant differences between modalities.
