MAXIMAL STRENGTH TRAINING IMPROVES WORK ECONOMY IN SKIERS
Hoff, J., Helgerud, J., & Wisloff, U. (1999). Maximal strength training improves work economy in trained female cross-country skiers. Medicine and Science in Sports and Exercise, 31, 870-877.
The effects of maximal, upper-body, skill-related strength training on the work economy and anaerobic threshold of double-polling ski ergometry were investigated in female cross-country skiers (N = 15). A high-intensity strength-training group (N = 8) and a non-strength-training group (N = 7) participated for nine weeks during which predominantly endurance work (running, roller skiing, and then skiing) was performed. Strength training was performed 3 days per week.
Work economy, but not anaerobic threshold, improved significantly in the strength-trained group. Time to exhaustion improved significantly for both groups with the strength group being significantly more than the control group.
Implication. Maximal, skill-related strength training improved work economy in female cross-country skiers.
