General Strength And Muscular Endurance: Relationship To V1- And V2-Skate Skiing Economy In Collegiate Cross-Country Skiers, Ian Torchia

All NMU Master's Theses

Introduction Cross-country skiing is a power-endurance sport requiring upper and lower body activation for propulsion across the ground. While high aerobic markers such as VO_2max and lactate threshold are important performance indicators, recent research has demonstrated the importance of full-body general strength and muscular endurance in skiing success. The purpose of this study was to examine the relationship of strength indices via a full-body series of muscular endurance tests, as well as a general 1-RM strength test, to VO₂ skiing economy utilizing the V1- and V2-skate technique.

Methods Oxygen uptake was measured during baseline and economy testing on …

A Comparison Of Stride Length And Lower Extremity Kinematics During Barefoot And Shod Running In Well Trained Distance Runners, Peter Francis, James Ledingham, Sarah B. Clarke Phd, Dj Collins, Philip Jakeman

Journal Articles

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 …
