The purpose of this study was to determine a strength gain of the quadriceps and hamstrings due to recreational cross-country skiing. Eleven subjects, four male and seven female, from two selected, beginning cross-country ski classes at Western Michigan University participated. For both the pretest and posttest, each subject performed five maximal, reciprocal contractions of the dominant and nondominant knee flexors and extensors. The data were collected on a Cybex II Dual Channel Dynamometer and Instrumentation System, #7104. Two Analyses of Variance, randomized block, factorial designs were used to analyze the dependent variable, torque, as it related to the independent variables of dominant and nondominant leg, pretest and posttest in the quadriceps and in the hamstrings. After skiing approximately 40 minutes per day, two days per week, for six weeks, the only significant result was that the participants experienced a significant increase in the strength of the dominant and nondominant hamstrings.
