Long conjugate sequence (LCS) resistance training enhances male skaters' strength without reducing power. Strength and power gains correlate with improved long-track and short-track speed skating performance.
Area of Science:
- Sports Science
- Exercise Physiology
- Biomechanics
Background:
- Long conjugate sequence (LCS) resistance training is utilized to improve strength and power for enhanced sport-specific performance in speed skating.
- Understanding the training adaptations and their relationship to performance is crucial for optimizing athlete development.
Purpose of the Study:
- To investigate changes in strength and power during alternating periods of an LCS program in speed skaters.
- To examine the correlations between strength, power, and competitive performance in both long-track (LT) and short-track (ST) speed skating.
Main Methods:
- Twenty-three sub-elite to elite speed skaters (16 men, 7 women) participated in a 39-week LCS program with alternating strength and power phases.
- Strength (Isometric Mid-Thigh Pull) and power (Squat Jump) were measured post-period.
- Linear mixed-effects models analyzed changes over time, sport, and sex; Kendall's tau correlations assessed strength/power relationships with performance.
Main Results:
- Absolute and relative strength increased significantly in male skaters throughout the season, while absolute power increased in the early season.
- Relative power remained stable across the training period.
- Higher absolute strength and power correlated with better LT and ST performance; relative strength was linked to ST, and relative power to early LT performance.
Conclusions:
- The LCS resistance training method effectively promotes strength development in speed skaters without negatively impacting power.
- These findings underscore the importance of resistance training adaptations for improving overall speed skating performance.

Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
Energy Diagrams - II
The point in the energy diagram at which the system’s potential energy is the lowest is known as the local minima. The system tends to stay in this position indefinitely unless acted upon by a net force. The slope of the potential energy diagram at the local minima is zero, indicating that zero net force is acting on the system. The slope...
