Purpose: Investigate sex differences in power, sprinting, and jumping performance following in-season high-load strength training and combined high-load and power training in high-level handball players. Methods: Twenty-seven players were divided into High-Load (HL; female: n=10, male: n=4) or Combined High-Load and Power (COM; female: n=8, male: n=5) training groups. Training was conducted twice weekly for 15 weeks. Pre- and post-measurements were leg press- and bench press maximal power (Pmax), countermovement jump (CMJ) height, change of direction (CoD) sprints, linear sprint (10-, 20-, 30m), and isometric rate of force development (RFD). Results: Females had higher training attendance than male (HL: female: 92±7%, male: 74±11%, p=0.001; COM: female: 92±7%, male: 71±10%, p=0.001). No sex differences were observed in the physical measurements in HL and COM (p=0.2-0.9; p=0.1-0.9). Leg Press Pmax (HL: 5.86% vs 2.77%; COM: 2.64% vs 0.58%), Bench Press Pmax (HL: 1.87% vs 0.61%; COM: -4.05% vs 1.7%), CMJ (HL: 1.20% vs 0.34%; COM: -1.82% vs -4.1), CoD (HL: 1.58% vs 0.69%; COM: -0.96% vs -3.78%), RFD 50-,100-,200ms (HL: 15.55-,15.09-,12.10% vs 0.93-,14.16-,27.35%; COM: 27.91-,15.84-,9.9% vs 9.72-,7.46-,5.58%), Linear Sprint 10-,20-,30m (HL: -1.19-,-0.84-,-0.24% vs -0.96-,-1.05-,-1.09%; COM: -0.81-,-0.21-,-0.03% vs 1.12-,-0.71-,-1.91%). Conclusion: Our results indicate no significant sex differences in training adaptation. It may seem that females exhibit a minor favourable response to training compared to males in both programs, potentially regarding training attendance. The study highlights meaningful individual differences, encouraging personalized training programs tailored to player's needs and qualities, regardless of sex.
