These selections are great for athletes to
improve their triple

Moreover, supplementation with BA for 4 — 10 weeks has been shown to increase

improve workload and time to fatigue during high intensity cardio [144 — 148],
improve muscle resistance to fatigue during strength training [149], increase lean mass by approximately 1 kg [147] and significantly reduce perceptions of fatigue [150].
In certain trials of older men and women, training with whole body vibration significantly
improved muscle torque and power, and were proportionately greatest in plantarflexion and to a lesser extent
knee extension, while hip flexion and
extension, and
knee flexion and dorsiflexion measures were unaltered.
Even the
knee extension can
improve vertical jump height (Augustsson et al. 1998; Friedmann - Bette et al. 2010).
