Stride length, hip, knee and ankle angles were compared during barefoot and shod running on a treadmill at two speeds. Nine well-trained (1500m time: 3min:59.80s ± 14.7 s) male (22 ±3 years; 73 ±9 kg; 1.79 ±0.4 m) middle distance (800 m – 5,000 m) runners performed 2 minutes of running at 3.05 m·s-1 and 4.72 m·s-1 on an treadmill. This approach allowed continuous measurement of lower extremity kinematic data and calculation of stride length. Statistical analysis using a 2X2 factorial ANOVA revealed speed to have a main effect on stride length and hip angle and footwear to …
Upper Body Characteristics Related To Double Pole Performance In Female Cross Country Skiers, Karmen M. Whitham
Upper Body Characteristics Related To Double Pole Performance In Female Cross Country Skiers, Karmen M. Whitham
All NMU Master's Theses
The purpose of the current study was to correlate upper body (UB) lean mass (UBLM), UB maximal strength (UBMS), and average power production during a 3-min ski ergometer (SERG) test to predict the dependent variable, a one-kilometer uphill double pole time trial (DPTT) on snow. We hypothesized UBLM would be most important to performance. All tests were conducted within four weeks of completing the championship phase of a Division I cross country (XC) ski season. Skiers (n=10; all females) performed the mass-start DPTT on snow (i.e., criterion measure), SERG, and UBMS separated by at least a few days recovery. Lastly, …

The Reactive Strength Index-Modified (RSlmod) is a reliable method of measuring the explosiveness of an athlete during a range of plyometric exercises. The purpose of the current study was to measure the between-limb differences in RSlmod across three different plyometric tasks. Eleven recreationally active participants performed countermovement jumps, stop jumps and single-leg jumps. The study found no significant differences in RSlmod between dominant and non-dominant limbs across all three tasks (p>0.05), but did find RSI,d to be higher in the stop jump than a countermovement jump and single leg stop jump for both dominant and non-dominant limbs. These findings …
7-Weeks Of Yoga Training And Its Effects On Flexibility, Rate Of Force Development, And Jump Height In Olympic Weightlifters, Andrew Ernst
7-Weeks Of Yoga Training And Its Effects On Flexibility, Rate Of Force Development, And Jump Height In Olympic Weightlifters, Andrew Ernst
All NMU Master's Theses
The purpose of the current study was to determine what effects 7-weeks of yoga training had on Olympic weightlifters flexibility, rate of force development, and jump height. Pre- and post-testing was performed consisting of flexibility and jump performance measurements. The participants performed a sit and reach test followed by a loaded overhead squat test with barbell. The overhead squat test was performed with reflective markers and recorded video to assess joint angles. A countermovement jump and snatch, at 80% of their one repetition maximum, was performed next to measure rate of force development and jump height. The participants then were …
