Specificity in power training, like combining squats and plantar flexion, enhanced movement power but did not improve vertical jump performance. Coordinative changes observed suggest potential for future improvements in jumping ability.

Area of Science:

  • Sports Science
  • Biomechanics
  • Exercise Physiology

Background:

  • Inter-joint coordination is crucial for explosive movements.
  • The transferability of training-specific coordination to performance is not fully understood.

Purpose of the Study:

  • To investigate if specific inter-joint coordination during power training enhances training effects.
  • To compare the impact of single-joint versus multi-joint power training on performance and coordination.

Main Methods:

  • 22 subjects participated in a 5-week training study, divided into two groups.
  • One group (Tsingle) performed squats (SQ) and plantar flexions (PL) separately.
  • The other group (Tmulti) performed a combined squat-and-plantar flexion movement (SQPL).

Main Results:

  • Both groups improved peak power in their training movements (2-15%) with no significant group differences.
  • No significant improvements in vertical jump performance were observed in either group.
  • Distinct coordinative changes occurred between groups during vertical jumping post-training.

Conclusions:

  • Power training increased movement-specific power but did not transfer to improved vertical jump performance.
  • Training-specific coordination changes were observed, suggesting they may be precursors to enhanced jumping ability.
