aim: was to assess the effects of ramadan observance upon repeated sprints and associated inflammatory and oxidative stress responses. methods: ten young trained boxers were tested during a control period (c), at the end of the first week (r-1), and during the fourth week of ramadan observance (r-4). on each occasion, they performed three vertical jumps, 10 x 6 s repeated sprints on a cycle erg...

background: the purpose of this study was to investigate the ratio of electromyography (em g) activities of the vastus medialis obliqus (vmo) and vastus lateralis (vl) within seven angles of knee joint range of motion using isometric contraction in open kinetic chain (ok c) and closed kinetic chain (ckc). methods: the dominant knees of 44 healthy female subjects (mean age: 24.84 with range: 20-...

the purpose of this study was to estimate the torque from high‑density surface electromyography signals of biceps brachii, brachioradialis, and the medial and lateral heads of triceps brachii muscles during moderate‑to‑high isometric elbow flexion‑extension. the elbow torque was estimated in two following steps: first, surface electromyography (emg) amplitudes were estimated using principal com...
