Nordic Walking Training for Older People
Condition: Sedentary Lifestyle; Age Problems
Study type: Interventional

Summary: 
      Objective: to assess by means of a randomized clinical trial the effects of eight weeks of
      Nordic walking and free walking training on quality of life (QoL), static balance, dynamic
      variability, self-selected walking speed (SWS) and locomotor rehabilitation index (LRI),
      parameters of pendular mechanism [external (Wext), internal (Wint) and total mechanical work
      (Wtot), Recovery (R), Cost of Transport (C)], Electromyographic parameters (Average signal
      and co-contraction of the Anterior deltoid (AD), triceps brachii (TB), vastus lateralis (VL),
      biceps femoris (BF), anterior tibial (AT) and medial gastrocnemius (MG) muscles, heart rate
      of exercise (HRexercise) - and the rate of perceived exertion (RPE), in sedentary elderly.
    

Detailed description: 
      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.

Intervention type(s): Other; Other
Intervention description(s): 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.; The training period begin for both groups, will be comprised of eight weeks of duration, with frequency of three weekly sessions.
