Is there a contextual interference effect for sub-elite alpine ski racers learning complex skills?

Area of Science:

• Motor learning
• Sports science
• Skill acquisition

Background:

• The contextual interference effect, typically studied in lab settings with artificial tasks, is theorized to enhance motor skill learning.
• Generalizing these findings to real-world sports contexts, like alpine skiing, remains challenging due to differing environmental and participant factors.

Purpose of the Study:

• To investigate the contextual interference effect in a natural sports environment.
• To examine the impact of interleaved versus blocked practice schedules on learning a new slalom technique in sub-elite alpine ski racers.

Main Methods:

• Sixty-six sub-elite alpine ski racers participated over a 3-day training period.
• Participants learned a pumping technique to increase slalom velocity using either an interleaved or blocked practice schedule across three different slalom courses.
• A retention test was administered 72 hours after the final practice session.

Main Results:

• Contrary to hypotheses, the interleaved practice group did not show significantly better retention than the blocked practice group.
• Performance during the skill learning phase was not significantly different between the interleaved and blocked groups.
• The study found no significant benefit of interleaved practice over blocked practice for this specific motor skill in this population.

Conclusions:

• The contextual interference effect may not universally enhance motor learning in naturalistic sports settings.
• Findings suggest that the effectiveness of practice schedules like interleaved and blocked practice can be context-dependent.
• Further research in ecologically valid environments is crucial for understanding motor learning principles beyond the laboratory.
