Do speed amplitude and period affect gait variability and step followability under sinusoidal speed changing conditions
Introduction The time courses of the joint elevation angles of the thigh, shank, and foot in one stride during walking can be well approximated by a “ plane ” in a triaxial space. This intersegmental coordination (IC) of the lower limb elevation angles is associated with gait variability. This study aimed to examine how anteroposterior and lateral gait variabilities are influenced by different amplitudes (±0.33 vs. ± 0.67 m·s −1 ) and periods (30…
Messaging effects and psychological drivers for conservation behaviors at Mt. Fuji, Japan
This study demonstrated the differences in behavioral changes caused by two conservation messages through field experiments in Mount Fuji, Japan. The target behavior was to use a cleaning mat set up on a mountain trail to remove non-native plant seeds from the soles of visitors' shoes. To further understand the drivers of behavioral change, a questionnaire survey was used to examine the influence of different conservation messages and psychologic…
Effects of exercise habituation and aging on the intersegmental coordination of lower limbs during walking with sinusoidal speed change
Background The time courses of the joint elevation angles of the thigh, shank, and foot in one stride during walking can be well approximated by a "plane" in a triaxial space. This intersegmental coordination (IC) of the lower limb elevation angles is referred to as the planar covariation law. We examined the effects of exercise habituation and aging on the thickness of the IC plane of the lower limbs under sinusoidal speed changing conditions. M…
Effect of Carbohydrate-Electrolyte Solution Including Bicarbonate Ion Ad Libitum Ingestion on Urine Bicarbonate Retention during Mountain Trekking
We investigated whether bicarbonate ion (HCO 3 - ) in a carbohydrate-electrolyte solution (CE+HCO 3 ) ingested during climbing to 3000 m on Mount Fuji could increase urine HCO 3 - retention. This study was a randomized, controlled pilot study. Sixteen healthy lowlander adults were divided into two groups (six males and two females for each): a tap water (TW) group (0 kcal with no energy) and a CE+HCO3 group. The allocation to TW or CE+HCO3 was do…
Does change in barometric pressure per given time at high altitude influence symptoms of acute mountain sickness on Mount Fuji? A pilot study
Background Acute mountain sickness (AMS) is a common, transient condition characterized primarily by headaches, and it can also be associated with fatigue, dizziness, and nausea with vomiting. The symptoms of AMS are most pronounced after the first night spent at a new altitude. At sea level, changes in barometric pressure per given time have been associated with migraine headaches. We sought to investigate whether changes in barometric pressure,…
Prevalence of Falls on Mount Fuji and Associated with Risk Factors
Since little is known about the detailed situations of falls on Mount Fuji, the aim of this study was to clarify the risk factors of falls on Mount Fuji in Japan. We conducted a questionnaire survey of 556 participants who had climbed Mount Fuji and collected the following information: fall situation, mental status, fatigue feeling, sex, age, climbing experience on Mount Fuji and other mountains, summit success, whether staying at a lodge, use of…
Impact of Wearing Graduated Compression Stockings on Psychological and Physiological Responses during Prolonged Sitting
We investigated the impact of wearing vs. not wearing graduated compression stockings on psychological and physiological responses in 18 healthy young people (12 men and six women) during 3 h prolonged sitting. Profiled of Mood States (POMS) scores did not show marked differences between with and without stockings. A 3 h sit significantly decreased saliva cortisol in both conditions; with no differences between conditions. Wearing stockings suppr…
Management Effectiveness of a Secondary Coniferous Forest for Landscape Appreciation and Psychological Restoration
We investigated the influence of forest management on landscape appreciation and psychological restoration in on-site settings by exposing respondents to an unmanaged, dense coniferous (crowding) forest and a managed (thinned) coniferous forest; we set the two experimental settings in the forests of the Fuji Iyashinomoroi Woodland Study Center. The respondents were individually exposed to both settings while sitting for 15 min and were required t…
Impact of Viewing vs. Not Viewing a Real Forest on Physiological and Psychological Responses in the Same Setting
We investigated the impact of viewing versus not viewing a real forest on human subjects' physiological and psychological responses in the same setting. Fifteen healthy volunteers (11 males, four females, mean age 36 years) participated. Each participant was asked to view a forest while seated in a comfortable chair for 15 min (Forest condition) vs. sitting the same length of time with a curtain obscuring the forest view (Enclosed condition). Bot…
