Background: The maximal oxygen uptake (VO2máx) assessment by indirect calorimetry is the most reliable method to determine VO2máx, but when repeated tests are conducted, the results have been controversial., Aim: To determine the reliability of the maximal oxygen uptake (VO2máx) in healthy adults following two consecutive trials with 10 min rest between trials using the Bruce protocol., Methods: Participants were 6 males apparently healthy physically active (Mean age=23,4±1,3 years), who performed twice the Bruce protocol and after reaching their VO2máx in the first trial they stepped down the treadmill and rested seated on a chair during 10 min., Results: The data analysis showed high reproducibility values between tests, indicated by the correlation coefficient Pearson product moment and R squared with confidence intervals at 95% (CI95%), the correlation of the maximum oxygen consumption was VO2máx =0.907 with a R2=0.823, the maximum heart rate was HRmáx=0.786, with R2=0.618 and the rate of ventilation and carbon dioxide elimination was VE/VCO2=0.868, with an R2=754. No adverse effects were reported during the 10 min rest between trials., Conclusion: Resting 10 min between consecutive maximal exercise tests using Bruce protocol treadmill tests does not affect VO2máx in healthy young adults. It is feasible and reliable to perform maximal treadmill tests in a single session without adverse effects for the participant., (Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

Background: Scientific evidence have been related negative functional autonomy to sedentary lifestyle in elderly women by other hand physical exercise is highly recommended to prevent deterioration of neuromuscular functions and proposed during the rehabilitation of physical disability and fall accidents., Aim: To determine the effect of periodized water exercise training on functional autonomy in elderly women., Methods: Twenty-six subjects were randomly assigned in two, water exercise intervention group (n=16) and control group (n=10); The intervention group followed 12-week of periodized water exercise training program five times a week, 30 minutes of water exercise with work heart rate reserve of 40-50% (1-6th week) increasing the load to 50-60% (7-12th week); The protocol of the Group of Latin-American Development for Maturity (GDLAM) was used to evaluate functional autonomy; As statistical analyses mixed 2 x 2 ANOVA was used, also percentage changes (Δ %) were calculated., Results: The results showed significant improvement (p<0.05) comparing the interaction intergroup and the measurements in 10 meters walk test (10mW) (p=0.001) and general GDLAM index (GI) (p=0.012), percentage changes (Δ %) showed positive improvements in the five components of (GDLAM) and (GI)., Conclusion: Periodized water exercise training program was able to enhance (10 mW) and (GI) however, will be appropriated in the future more studies to better clarify the possibilities of improvements between water exercise and functional autonomy., (Copyright AULA MEDICA EDICIONES 2014.

This case study attempts to determine the effect of a hydrokinesitherapy program by means of the Halliwick method on physical fitness in a female aged 35 years with poliomyelitis sequelae. The intervention followed sixteen weeks of hydrokinesitherapy during 70 minutes, five times a week, where we carried out exercises from the Halliwick method. There was an assessment both before and after the application. Strength endurance and flexibility were determined according to a senior fitness test protocol. The results showed positive improvements when carrying out the exercises from the Halliwick method and the percentage change (Δ%) of strength endurance increase 361.5% in the right arm and 300% in the left arm. Flexibility increased 2 cm in the right shoulder and 10 cm in the left shoulder. In conclusion the subject was able to improve the performance of Halliwick exercises while showing an increase in strength endurance and flexibility., (Copyright AULA MEDICA EDICIONES 2014.
