Abstract
The focus related to Heart Rate (HR) knowledge in children in the aquatic environment already
has some decades and continues to be an interest and constant research. This study intends to characterize and evaluate the level of cardiovascular responses regarding motor skills with aquatic exercises through the analysis of heart rate. The participants were 10 infants with a mean age of 17.6 months and all of them with 9 months of previous practice of water activities. Data collection was performed by a portable HR monitor with a band adjusted to the infant's chest. The highest heart rate value recorded was 194 bpm and the lowest one of 92bpm.
Ventral, dorsal and vertical positions were analyzed, jumps and finally immersion. All sessions were recorded with a video camera at the same time it was made the heart rate assessments for synchronizing tasks times. For statistical analysis of the values, a comparison between infants’ activities was assessed, using the T-Test to compare means of the different aquatic skills. The higher mean recorded was in jump, with a mean value of 141.3±17.65 bpm, compared with the lowest mean the ventral position task with a mean value of 119.2±22.78 bpm. There were changes on the HR associated with the tasks performed, where each motor ability showed different cardiovascular responses.
