Core Stability e controllo posturale: effetti a breve termine indotti dallo strumento Bosu®
No full textoday core stability and strenght exercises are commonly part of many training programs.
Despite the good number of articles about this field, only few research analyzed the relation between core training and postural control.
The aim of present work is to define the short-term effects of 3 core stability exercises performed with matwork and Bosu® on postural data.
15 healthy and physically active people have been tested pre and immediately post exercises with stabilometric platform in eyes open and closed condition; center of pressure displacements on medio-later and sagittal plane and range of displacements have been evaluated to find possible after training benefits
Core training e dispendio energetico: confronto tra esercizi eseguiti con gli strumenti bosu® e gliding
No full textIl Core Training rappresenta oggi una metodologia ampiamente diffusa in ambito preventivo, rieducativo
ed allenante. Tuttavia, nonostante le crescenti evidenze scientifiche a sostegno del suo utilizzo, alcuni dubbi rimangono
circa la reale efficacia di determinati strumenti e le finalità condizionali di tale metodica, uniti ad una
non completa chiarezza terminologica. Tra questi, il Bosu® ed il Gliding sono notevolmente utilizzati nel settore
del fitness per incrementare il controllo neuromuscolare ed indurre aumenti nel consumo calorico, senza
però indicazioni scientifiche adeguate. Scopo del presente studio è di quantificare il dispendio energetico
di 60’ di core training eseguito con una superficie instabile (Bosu®) ed una scivolante (Gliding) tramite lo strumento
ArmBand, al fine di valutarne possibili differenze in giovani adulti sani

EFFECTS RESISTANCE EXERCISE AND STRENGTH TRAINING ON ANTROPOMETRIC MEASURE AND IMPROVEMENT OF PHYSICAL EFFICIENCY IN ADULT WITH METABOLIC SYNDROME
Full text linkIt has been recognized by OMS that physical exercise has a therapeutic tool for the prevention and treatment of various diseases and that its reduction is one of the major risk factors for disease. The objective of this study was to analyses the effects resistance training combined strength training on index form and antropometric measure on subjects with metabolic syndrome
PARABOLIC FITTING OF ISOTONIC POWER-ANGLE CURVES TO EVALUATE MOTOR DEFICITS IN PATIENTS SUBMITTED TO ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION
No full textPower-angle curves, describing the isotonic sub-maximal movement of the lower extremities, are better means to evaluate the effects of training protocols and to highlight functional differences between the legs. The aim of this work was to compare the morphology of power-angle curves of pathological subjects (PS) and healthy subjects (HS) and to evaluate the feasibility of this approach to discriminate between pathological and healthy legs. Isotonic evaluation with leg-extension machine was performed on 46 HS and 16 PS previously submitted to knee surgery. The healthy group comprised 33 elderly healthy subjects (EHS) (mean: 65 years) and 13 young healthy subjects (YHS) (mean: 35 years) and the influence of age on the curves was evaluated. All subjects performed a sub-maximal movement with the legs working alone and together. Each curve was interpolated with a parabolic function and the R 2 Pearson coefficient was used as a score for morphological regularity. R2 of curves of PS obtained with legs working alone were statistically different from those of the HS group, considering both YHS and EHS (p < 0.05). Statistically significant differences between YHS and EHS (p < 0.01) show the importance of age in the modality of performing movements. © 2010 World Scientific Publishing Company
EFFECTS OF 6 WEEKS BALANCE AND MOBILITY TRAINING ON POSTURAL CONTROL IN HEALTY SUBJECTS
No full textPostural training is commonly performed in clinical, fitness and sport fields to improve performance and wellness. Despite his wide diffusion for healthy and unhealthy people, confusion still exist about focus, time and kind of training and many different techniques are currently suggested.
The aim of this study is to analyze the effect of 6 weeks training time using Bosu Balance Trainer® and Pancafit ® tools on postural control in healthy subjects.
Nineteen healthy subjects volunteered for the study. They were divided in training (TG - n:10) and control (CG - n:9) group. TG trained for 6 weeks, 3 times per weeks, 60 minutes per session with focus on balance and mobility (30 minutes each one). Training program was settled with specific progression in both components to continuously stress the neuromuscular system. Postural control using stabilometric platform in eyes open (EO) and closed condition (EC) and spine mobility (SPINE) were assessed pre and post training.
TG improved center of pressure (COP) area and displacement in EO and EC conditions, while CG in EO condition only. TG
showed better improvements compared to CG for both COP measures, even if not significantly. TG improved SPINE in lumbar region and during trunk flexion, even if not significantly (p>0.05), while no improvements were observed in CG.
These findings suggest that a short time (6 weeks) training time with same focus on balance and mobility could lightly improve postural control and spine mobility in healthy subjects. Bosu Balance Trainer® and Pancafit ® are efficient tools for this kind of training
MUSCLE ACTIVATION UNDER DIFFERENT ANKLE AND KNEE POSITIONS DURING LEG EXTENSION EXERCISE
No full textBACKGROUND: The imbalance between vastus medialis oblique (VMO) and vastus lateralis (VL) is one of the mean factor for (PFPS) onset, related to improper alignment of the patella. PURPOSE: The aim of this study is to investigate the effects of knee flexion, knee rotation and ankle flexion attitudes on the activity of the VMO and VL muscles during unilateral maximal voluntary isometric contraction (MIVC) of the quadriceps femoris. METHODS: Ten healthy subjects volunteered for the study. Five conditions for two different knee flexion angles (90°; 30°) were tested: neutral condition, maximal knee medial rotation, maximal knee lateral rotation, maximal ankle plantarflexion and maximal ankle dorsiflexion. Data were normalized in order to calculate the normalized VMO/VL ratio. CONCLUSIONS: The normalized VMO/VL ratio for all the conditions occurred at 90° of knee flexion was higher than the same conditions at 30° of knee flexion (p=0.04), due to a lower level of activity of the VMO. No statistically differences between conditions at the same knee angle were observed, with only exception for lateral rotation at 30° knee flexion (p<0.05). These findings suggest that knee flexion is the main factor to be considered to improve VMO activity during leg extension exercis
Esporte e atividade física na idade avançada: incidência nas alterações do equilíbrio
Full text linkIntrodução: O presente trabalho foi conduzido com o objetivo de pesquisar os efeitos que o esporte e a atividade física podem exercer nas alterações do equilíbrio estático nas pessoas idosas. Materiais e Métodos: Para o estudo foram recrutadas 30 pessoas saudáveis, de ambos os sexos e de idade entre 65 e 75 anos. Os sujeitos que resultaram capazes preencheram o questionário Minnesota sobre a atividade física praticada e fizeram 6 testes diferentes na plataforma estabilométrica, dependendo das indicações do Smart Balance Master da Neurocom International. Os dados foram submetidos ao teste, de tipo não paramétrico, de Wilcoxon e Mann-Whitney. P < 0,05 foi considerado significativo. Discussão: A análise dos dados não evidenciou diferenças significativas na comparação entre os grupos
(0,1 < p< 0,9). Não obstante isso é importante evidenciar que, em quase todas as variáveis examinadas, os valores mostram claras diferenças em favor da população esportiva (nos sujeitos esportivos: redução média SUP= 0,05 ± 0,07cm2 ; redução média X= 0,07 ± 0,06cm; redução média Y= 0,06 ± 0,09cm). Isso nos leva a afirmar que a prática de atividade esportiva, na idade avançada, tem um papel não indiferente nas capacidades de anutenção do equilíbrio estático, se comparada com a atividade físic
