“…Most prior studies investigating turning used walking paths or destination cues with no obstacle (Akram et al, 2010; Chang and Kram, 2007; Courtine and Schieppati, 2003; Hicheur and Berthoz, 2005; Hicheur et al, 2007; Hicheur et al, 2005; Jindrich et al, 2006; Olivier et al, 2008; Orendurff et al, 2006; Patla et al, 1991 and 1999; Pham et al, 2007; Taylor et al, 2005; Yamaguchi et al, 2012a, b), while other obstacle circumvention studies used 2 m high pylons (Gérin-Lajoie et al, 2006, 2007, and 2008; Vallis and McFadyen, 2003, 2005), 1.53 m tall poles (Glaister et al, 2007b and 2008) or pedestrian barricades (Dias et al, 2013). The present results indicate the height of the corner could be an important factor in the study design.…”

Despite the prevalence of directional changes during every-day gait, relatively little is known about turning compared to straight gait. While the center of mass (COM) movement during straight gait is well characterized, the COM trajectory, and the factors that influence it, are less established for turning. This study investigated the influence of a corner’s height on the COM trajectory as participants walked around the corner. Ten participants (25.3 ± 3.74 years) performed both 90° step and spin turns to the left at self-selected slow, normal, and fast speeds while walking inside a marked path. A pylon was placed on the inside corner of the path. Four different pylon heights were used to correspond to heights of everyday objects: 0 cm (no object), 63 cm (box, crate), 104 cm (desk, table, counter), 167 cm (shelf, cabinet). Obstacle height was found to significantly affect the COM trajectory. Taller obstacles resulted in more distance between the corner and the COM, and between the corner and the COP. Taller obstacles also were associated with greater curvature in the COM trajectory, indicating a smaller turning radius despite the constant 90° corner. Taller obstacles correlated to an increased required coefficient of friction (RCOF) due to the smaller turning radii. Taller obstacles also tended towards greater mediolateral (ML) COM-COP angles, contrary to the initial hypothesis. Additionally, the COM was found to remain outside the base of support (BOS) for the entire first half of stance phase for all conditions indicating a high risk of falls resulting from slips.

“…46 A study of spatial navigation differences in female athletes and non-athletes showed that the elite athletes, such as soccer, field hockey, and basketball, had faster walking times during the navigation of all obstructed environments by processing visuo-spatial information faster and navigating through complex, novel environments at greater speeds. 47 …”

The differences of learning and memory between males and females have been well documented and confirmed by both human and animal studies. The sex differences in cognition started from early stage of neuronal development and last through entire life span. The major biological basis of the gender-dependent cognitive activity includes two major components: sex hormone and sex-related characteristics, such as sex-determining region of the Y chromosome (SRY) protein. However, the knowledge of how much biology of sex contributes to normal cognitive function and elite athletes in various sports are still pretty limited. In this review, we will be focusing on sex differences in spatial learning and memory – especially the role of male- and female-type cognitive behaviors in sports.

“…Sandbags were placed at the bottom of the obstacle to stand them upright. The same obstacle was used previously with healthy youth ice hockey players [20] and a similar obstacle has been used previously with adult athletes [22]. Prior to each trial that included obstacle avoidance, the participants were provided instruction specific to which direction they were to circumvent the obstacle (left or right).…”
