| description | Background: Jump-landing is a major cause of lower limb injuries. This study investigated
the effect of various aerial catching movements on the co-contraction index (CCI)
of the knee and ankle muscles, as well as on joint angular displacements and
joint moments during landing. Methods: Fifteen right-hand dominant collegiate basketball
players (age: 21.0 ± 1.2 years; weight: 79.9 ± 7.9 kg; height: 180.9
± 5.5 cm; training experience, 5.6 ± 3.5 years) performed maximal
countermovement jumps under four conditions: no catching (NC), right (RULC), left
(LULC) and bilateral (BULC) upper-limb catching. Electromyography of the rectus
femoris (RF), biceps femoris (BF), lateral gastrocnemius (LG) and tibialis
anterior (TA), along with kinematic and kinetic data, were recorded during
landing. The co-contraction index (CCI) of knee and ankle muscles before and
after landing, as well as angular displacements and peak joint moments were
calculated. Results: When compared to the NC condition, all aerial catching movements
resulted in reduced knee flexion (RULC, p = 0.004, d = −1.11;
LULC, p < 0.001, d = −1.52; BULC, p = 0.013,
d = −0.97) and increased ankle dorsiflexion (RULC, p = 0.002,
d = −1.21; LULC, p = 0.004, d = −1.13; BULC, p
< 0.001, d = −1.50) angular displacement after landing, along with
significantly higher CCI of RF-BF (RULC, p = 0.018, d = 0.93;
LULC, p = 0.033, d = 0.85; BULC, p = 0.042, d
= 0.81) and LG-TA (RULC, p = 0.025, d = 0.88; LULC, p
= 0.004, d = 1.12; BULC, p = 0.015, d = 0.95) before
landing, the LULC condition led to greater knee abduction angular displacement
(p = 0.002, d = 1.19) and moment (p = 0.001,
d = 1.26), and lower RF-BF CCI after landing (p = 0.037,
d = 0.83). Aerial catching movements increased lower limb muscle
co-contraction before landing and led to greater knee stiffness after landing.
However, LULC reduced knee co-contraction and increased frontal plane knee motion
after landing, indicating decreased joint stability and higher injury risk.
Conclusions: Injury prevention programs should incorporate upper limb coordination and
perturbation training—especially for the left arm—to enhance motor control
and joint stability during sport-specific tasks. |
