Abstract

The purpose of this study was to identify the effects of 60-minute walking workouts using nordic walking poles on skin
temperatures, and examine differences in body heat changes between nordic walking and general walking. Infrared thermal
imaging was measured in healthy male and female adults (nordic 17, general 16). The participants were attached radial
markers on upper extremity, trunk, and lower extremity to be recognized accurately. After attaching the markers then
measured standard skin temperature by Digital Infrared Thermal Imaging (IRIS-XP, MEDI-CORE, Co., Ltd., Seoul, Korea).
Both group walked for 60 minutes, the retest were taken 4 times per 20 minutes. Region of interest was set at below the
radial marker and compared average value between nordic walking and general walking. For nordic walking, all muscles
except the triceps in the upper extremity showed statistically significant differences in body heat changes according to
time variations (0,20,40,60) (<0.05). Nordic walking showed statistically significant differences in body heat changes in
the external oblique, rectus abdominis, and erector spinae of the trunk (p<0.05), and the body heat decreased during the
workouts. Nordic walking showed statistically significant differences in the rectus femoris and hamstring of the lower
extremity (p<0.05) and the body heat decreased with time. Human skin temperature declines during both nordic walking
and general walking.

Abstract

Objectives: This study aims to identify the effects of circuit weight training and weight training on foot pressure. Methods/ Statistical Analysis: The 20 young participants were divided into a Circuit Weight Training Group (CWTG) and a Weight Training Group (WTC) with ten participants in each group. A gait analyzer was utilized to assess on plantar pressure of subjects. The plantar pressure of ten spots was measured and analyzed. A paired samples t-test was used before and after the exercise in the CWTG and the WTG. Findings: This study shows the two groups’ changes in plantar pressure after the exercise as compared to before the exercise. The CWTG saw a significant increase in plantar pressure in two of the ten areas (F6, R1) and the WTG saw a significant increase in five of the ten areas (F4, F5, F6, R3, R4). After the four-week exercise program, the WTG’s plantar pressure significantly increased in five of the ten areas of the sole, with a significant increase in the middle foot. The CWTG’s plantar pressure significantly increased in two of the ten areas of the sole, the great toes and the outer areas of the heels. This means that the CWTG’s plantar pressure is closest to the normal movement of plantar pressure. Improvements/Applications: The CWTG exercise method resulted in a normal gait pattern, which had a more positive effect on gait than weight exercise.
