Comparing consumption oxygen during and after squat exercise in Smith Machine and whole-body vibration

Currently the physical exercise in whole body vibration platforms has become popular among people that frequenting gym and physiotherapy clinics. The objective of this study was to compare the oxygen consumption in the squat exercise performed at Smith Machine and squat performed on the vibration platform following the protocols usually referenced in both types of exercise (with load of 70% in the Smith Machine and unloaded on the vibration platform). The sample consisted of eight male subjects, with a mean age of 22.75 ± 2.05 years, an average body mass 74.50 ± 9.50kg, a stature of 1.79 ± 0.63m and estimated body fat percentage of 5.01 ± 0.94%. The volunteers performed two exercise sessions, one in the Smith Machine (AGSM) and the other on the vibration platform (AGPP). Each session consisted in 5 sets of 10 repetitions each, with a cadence of 40 beat.min(-1). The load used in the exercise AGSM performance was 70% of 1RM and in the AGPP was used a vibration frequency of 50 Hz, during 60 seconds in high amplitude. The order of the sections was randomized, with seven days apart. The AGPP session presented VO2 absolute = 0.95 ± 0.21L/min, VO2 relative = 12.86 ± 2.43ml/kg/min, and HR = 93.69 ± 10.55 beats/min; and the AGSM session presented VO2 absolute = 1.33 ± 0.29 L/min, VO2 relative = 17.91 ± 2.70 ml/kg/min, and HR = 120.69 ± 14.21 beats/min. The VO2 and HR values of the AGSM session were significantly higher than that found in AGPP session.

Description of the Pediasuit ProtocolTM

INTRODUCTION: PediaSuit ProtocolTM is an intensive therapy with a holistic approach to the treatment of individuals with neurological disorders like cerebral palsy (CP), developmental delays, traumatic brain injuries, autism and other conditions which affect a child's motor and/or cognitive functions. OBJECTIVE: The aim of the present work is to describe the PediaSuit ProtocolTM. METHODS: The authors team remained two months observing the care provided in a clinic with physical therapists trained by the PediaSuit ProtocolTM team (USA). RESULTS: The PediaSuitTM is a therapeutic protocol which uses a suit combined with intensive physical therapy and consists of up to four hours of therapy a day, five days a week, during three or four weeks. The PediaSuit ProtocolTM is customized to fit the needs of each child, with specific functional goals, and usually involves an intensive rehabilitation program. It combines the best elements of various techniques and methods, and has a sound rationale based on exercise physiology. CONCLUSION: This protocol anticipates results obtained only with long periods of conventional physical therapy.
