Tendons are able to respond to mechanical forces by altering their structure, composition,
and mechanical properties—a process called tissue mechanical adaptation. The fact that …

Background For the past 30 years, the hamstring (H)-to-quadriceps (Q)(H: Q) torque ratio
has been considered an important index of muscle strength imbalance around the knee …

Isokinetic moment ratios of the hamstrings (H) and quadriceps (Q) muscle groups, and their
implication in muscle imbalance, have been investigated for more than three decades. The …

The purpose of this brief review is to examine the neural adaptations associated with
training, by focusing on the behavior of single motor units. The review synthesizes current …

Background. To compare hamstring to quadriceps muscle coactivity during level walking,
stair ascent, and stair decent between individuals with and without knee osteoarthritis …

The purpose of this study was to examine the co-activation of the rectus femoris (RF) and
biceps femoris (BF) during drop jumping exercises using the co-contraction index (CI). Ten …

Temporal biomechanical and physiological responses to physical activity vary between
individual hamstrings components as well as between exercises, suggesting that hamstring …

The objective of this study was to determine the effects of fixed foot and functionally directed
balance training on static balance time, muscle activation during landing, vertical jump …

In this study, we estimated the specific tensions of soleus (Sol) and tibialis anterior (TA)
muscles in six men. Joint moments were measured during maximum voluntary contraction …

OBJECTIVE: To present the properties of an eccentric contraction and compare
neuromuscular and muscle–tendon system adaptations induced by isotonic and isokinetic …
