, with advancing age there is also increasing impairment of many aspects of vision ( Ball, Beard, Roenker, Miller, & Griggs, 1988 ; Elliott, Whitaker, & MacVeigh, 1990 ; Klein, Klein, Linton, & De Mets, 1991 ; Kosnik, Winslow, Kline, Rasinski, & Sekuler, 1988 ; Leat et al., 2013 ). Many of these

During a back tuck somersault, the angular velocity of the head is thought to surpass the visual system's ability to maintain a distinct and continuous picture of the environment. The primary objectives of this research were to determine if differences existed with regard to trunk and lower body kinematics, as well as landing balance, when gymnasts perform back tuck somersaults under different vision conditions. Ten female gymnasts (age = 11.6 ± 2.67 years, competitive level = 8 ± 1.15, and training time in gymnastics = 5.9 ± 1.63 years) performed back tuck somersaults under 4 vision conditions while wearing electromagnetic sensors that allowed automatic digitizing. Although no significant differences were found between vision conditions with regard to timing, joint angles, and joint angular velocities, gymnasts were more stable at landing under conditions that allowed vision during either the entire somersault or the last half of me somersault.

This is still a widely-accepted interpretation, one that continues to be heralded in motor development textbooks despite discoveries in the past 25 years increasingly pointing toward a different process explanation of how infants are learning to reach

Specifically, the SOT engages a sway-referenced support condition to knockdown the somatosensory system and a sway-referenced vision (SRV) condition to knockdown the visual system. The SOT provides a standardized assessment of sensory

Low levels of physical activity in this group may be due to factors such as fear of falling, lack of access to adapted recreational and athletic programs for those with vision impairment, and help or encouragement in developing suitable and safe physical recreation

As the new Editor of the “new” Women in Sport and Physical Activity Journal (WSPAJ), and someone who has been a reviewer, editorial member, author and reader since WSPAJ began publishing in 1992, I offer my historical perspective and my vision for WSPAJ. First, I am honored to be entrusted with the editorship as WSPAJ moves into its new home at UNCG, and I am committed to ensuring that WSPAJ is the leading publication for scholarship on women’s sport and physical activity. My vision for WSPAJ stems from its roots, and thus, I begin this editorial with an overview of the history of WSPAJ. Then, I will outline our mission and vision for WSPAJ. Finally, I invite all who are committed to women’s sport and physical activity to join our WSPAJ team.
