Effects of 12 weeks of Nordic Walking and XCO Walking training on the endurance capacity of older adults.

BACKGROUND

Several studies have already examined the positive effects of various forms of endurance training in patient groups and in healthy adults up to 60 years old. The aim of this study was to analyse the effects of Nordic Walking (NW) and XCO Walking (XCO) training on endurance capacity in healthy older adults, aged 60 years and older.

METHODS

Twenty-three older participants (mean age: 69.9 ± 5.4 years) were randomly assigned to either the NW group or the XCO group. All participants were measured before and after the 12 weeks of endurance training (2 sessions/week) to examine oxygen uptake (VO) and energy consumption during an outdoor field test. In addition, heart rates were recorded and lactate samples were collected.

RESULTS

NW mainly demonstrated some significant ( < 0.05) decreases in heart rate, lactate concentration at lower to moderate walking speeds, whereas XCO Walking revealed significant ( < 0.05) decreases in lactate concentration and VO at low to higher walking speeds.

CONCLUSIONS

NW as well as XCO training increase the efficiency of the cardio-vascular system in older subjects. Both training approaches are suitable options for endurance training, which may serve to counteract age- and inactivity-related decreases in cardio-vascular functioning as well as aid in maintaining overall performance in older adults.
