Recent trends in pairs figure skating (PFS) have shown that increasingly difficult jumps are essential for high-level performance and that powerful performance must be sustained through an entire competitive program.

PURPOSE: To determine the relationship between male and female PFS across six, ten-second time intervals (TI) of a 60s repeated jumps test.

METHODS: Eighteen male-female pairs (Males: Age 22.72(2.7) yr, Height 178.6(7.5) cm, Mass 77.5(7.0) kg) (Females: Age 18.3(3.4) yr, Height 155.6(5.0) cm, Mass 47.5(6.3) kg) of the U.S. National Team PFS were assessed. Following a self-selected warm up, each athlete performed a 60s repeated jump test on a large computerized switch mat with both flight time and ground time recorded on each jump and landing. Athletes maintained hands on hips throughout and achieved approximately a 90 degree knee flexion at the lowest point of each jump. The 60s test period was divided into 6, 10s TIs with average power (W·kg-1) calculated for each TI resulting in six data points for each subject. Each TI average power value was correlated (Pearson) between males and females.

RESULTS: Average power values (Mean(SD) W/kg) for each TI were (Males: 0-10s 20.5(2.4), 10-20s 24.4(3.0), 20-30s 22.4(3.3), 30-40s 19.9(3.0), 40-50s 17.8(3.4), 50-60s 16.1(2.7)) (Females:: 0-10s 16.9(1.8), 10-20s 19.0(2.5), 20-30s 17.6(2.9), 30-40s 15.7(2.0), 40-50s 13.8(1.8), 50-60s 12.4(2.2)). The correlations between male and female PFS on average power over the 10s TIs were the following: 0-10s, r = 0.65, p =0.003; 10-20s r = 0.69, p = 0.002; 20-30s, r = 0.78, p <0.001; 30-40s, r = 0.92, p < 0.001; 40-50s, r = 0.48, p = 0.045; 50-60s, r =.15, p = 0.57.

CONCLUSION: The correlations vary in strength from small (50-60s) to nearly perfect (30-40s) of the 60s repeated jumps test TI time segments. Male versus female PFS repeated jumps test abilities significantly correlate through five of the six testing TIs. This may demonstrate the relationship of male and female PFS common training and may provide assistance to practitioners when "pairing" figure skaters for training and performance.
