Descrição detalhada
Introduction: Considering the increase in the elderly population and their life expectancy, together with the expansion of Nordic walking (NW) interventions as a training method for the elderly, there is a need of preventive studies of RCTs and with methodological good quality approach to enable physical education, health and rehabilitation professionals to make decisions regarding the type, the volume and the intensity of NW exercise in promoting the health of the sedentary elderly.
Objectives: The aim of this study is to evaluate, through a randomized clinical trial, the effects of eight weeks of NW and FW training on quality of life (QoL), static balance, dynamic variability, self-selected treadmill walking speed (SSWSTreadmill), Locomotor rehabilitation (LRI) Parameters of Pendular Mechanism (external, internal and total mechanical work -Wext, Wint, Wtot, Recovery -R,Cost of Transport - C), Electromyographic parameters (Average signal and co-contraction of the AD, TB, VL, BF, AT and MG muscles), heart rate of exercise - HRexercise and the rate of perceived exertion (RPE), in sedentary elderly. of sedentary elderly.
Experimental Design: Randomized Controlled Clinical Trial (RCT).
Study Site: School of Physical Education, Physiotherapy and Dance (ESEFID), Federal University of Rio Grande do Sul Porto Alegre, Rio Grande do Sul, Brazil.
Methods: The sample comprised 33 sedentary participants randomly divided into two groups (Nordic walking group and Free walking group who will perform training for 8 weeks.

Experimental: Nordic walking
Experimental: Nordic walking Training The total period of training was composed by 8-week of walking with poles, three sessions per week.
The cycles were divided into eight microcycles composed by three training sessions.
Each training session took 60 min.
Nordic walking aerobics training were used during the training period.
These exercises were performed alternating volume and intensity.
Exercise intensities were controlled using the cardiac monitor, and the zone was since 70% to 105% of the heart rate at the second ventilatory threshold.
And volume was controlled using the time of the session.
|
The training period begin for both groups, will be comprised of eight weeks of duration, with frequency of three weekly sessions.
Volume (session duration in minutes) and intensity (percentage of the heart rate at second threshold ) were the same for both groups, only differing in the use (NW) or not of the poles (FW).
Each session will have of the Initial Part or warming-up, the Main Part and Final Part or cooling-down.

Experimental: Free Walking
Experimental: Free walking Training The total period of training was composed by a 8-week cycles of walking without poles, with three sessions per week.
The cycles were divided into eight microcycles composed by three training sessions.
