Muscle Imbalances: Testing and Training Functional Eccentric Hamstring Strength in Athletic Populations

15.9K
The hamstrings are a group of muscles that are sometimes problematic for athletes, resulting in soft tissue injury in the lower limbs. To prevent such injuries, functional training of the hamstrings requires intensive eccentric contractions. Additionally, hamstring function should be tested in relation to quadricep function at different contraction...

Radical Reactivity: Concentration Effects

1.8K
In a radical reaction, the concentration of starting materials governs the selectivity of a radical. For example, the reaction between an alkyl halide and an alkene, in the presence of tin hydride and AIBN, begins with the generation of a tin radical. The generated radical then abstracts halogen from the alkyl halide, producing an alkyl radical. This alkyl radical can either react with tin hydride, yielding an alkane, or add to an alkene, generating a nitrile-stabilized radical, eventually...

Summary

Unilateral eccentric training (ET) significantly enhances contralateral strength more than concentric training (CT). Progressive ET also offers greater muscle damage protection than a single eccentric bout, demonstrating a stronger cross-education effect.

Area of Science:

  • Exercise Physiology
  • Muscle Physiology
  • Sports Science

Background:

  • Unilateral resistance training is known to induce strength gains in the contralateral limb via the cross-education effect.
  • Repeated bouts of eccentric exercise can attenuate subsequent muscle damage, even when performed on the contralateral limb.

Purpose of the Study:

  • To compare the effects of unilateral eccentric training (ET) and concentric training (CT) on maximal voluntary isometric contraction (MVC) strength and muscle damage in the contralateral elbow flexors (EF).

Main Methods:

  • Young men participated in ET, CT, ipsilateral repeated bout (IL-RB), and contralateral repeated bout (CL-RB) groups.
  • Training involved unilateral EF contractions with increasing intensity over 5 weeks, followed by maximal eccentric contractions (30MaxEC) on the contralateral limb.
  • Repeated bout groups underwent two bouts of 30MaxEC separated by 1-2 weeks, either on the same or contralateral limb.

Main Results:

  • Maximal voluntary isometric contraction (MVC) strength increased significantly more in both trained and untrained arms for the ET group compared to the CT group.
  • Muscle damage markers were significantly reduced after the second bout in both IL-RB and CL-RB groups.
  • Eccentric training (ET) and CT attenuated muscle damage, with ET showing a greater protective effect than CL-RB, but less than IL-RB.

Conclusions:

  • The cross-education effect is more pronounced with eccentric training (ET) compared to concentric training (CT).
  • Progressive eccentric training provides a greater protective effect against contralateral muscle damage than a single bout of eccentric exercise.
