Kinematic Comparison Of Underwater Dolphin And Flutter Kicking Performed In A Prone And Supine Body Position, Peter Robinson, Taylor L. Adams, Kali Rose, Mickey B. Scharbrough, Scott P. Mclean

International Journal of Exercise Science: Conference Proceedings

Despite an increasing emphasis on underwater dolphin kicking in competitive swimming, little objective research exists to explain its preference over flutter kicking. PURPOSE: To examine kinematic characteristics of flutter and dolphin kicking performed in prone and supine body positions. METHODS: Ten collegiate swimmers (1.77±0.07 m, 72.4±7.6 kg, 19.8±1.0 yrs) experienced with dolphin and flutter kicking completed eight 10 m maximal effort underwater kicking trials. Body position and kicking style were randomly varied between trials such that half of all trials were performed using each kicking style and each body position. A calibrated underwater camera was used to record …

3-Dimensional Biomechanical Comparison Of Spinal Posture In Yoga Practitioners And Non-Practitioners During A Seated And Standing Position, Savannah V. Wooten

International Journal of Exercise Science: Conference Proceedings

Yoga has been claimed to be beneficial for helping a series of clinical populations and improving ailments such as, but not limited to, stress, chronic back pain, muscle endurance, flexibility, balance, and posture. Whereas many of the above listed assertions have been scientifically investigated, there is a lack of objective evidence that supports the claim that yoga improves posture. PURPOSE: The purpose of this study is to compare a 3-D biomechanical analysis of spinal posture among yoga practitioners (YP) and Non yoga practitioners (NP) during seated and standing positions. METHODS: 10 yoga practitioners (M= 3, F=7) and 10 …

Exploiting Arm Swinging Dynamics To Reduce The Metabolic Cost Of Walking While Carrying Loads, Obioma B. Mcreynolds, Christopher J. Arellano

International Journal of Exercise Science: Conference Proceedings

Arm swing while walking at one’s optimal speed is primarily driven by passive pendulum mechanics, an energy saving mechanism that has been speculated to incur little to no metabolic cost. PURPOSE: In line with this idea, we set out to determine whether carrying loads on the swinging and non-swinging arms while walking would be less costly than carrying loads at other locations on the body. We hypothesized that carrying loads on the arms while restricted from swinging would demand a greater metabolic cost than carrying loads on the arms while naturally swinging. For relative comparisons, we also explored the cost …

What Determines The Metabolic Cost Of Human Running Across A Wide Range Of Velocities?, Shalaya Kipp, Alena Marie Grabowski, Rodger Kram

International Journal of Exercise Science: Conference Proceedings

The cost of generating force hypothesis proposes that the metabolic rate during running is determined by the rate of muscle force development (1/t_c, t_c=contact time) and volume of active leg muscle. A previous study assumed a constant recruited muscle volume and reported that the rate of force development alone explains ~70% of the increase in metabolic rate for human runners across a moderate velocity range (2-4 m s^-1). PURPOSE: We performed a more systematic analysis of the effective mechanical advantage (EMA) of the lower leg over a wide velocity range to determine if …
