INTRODUCTION Physical exercise is an important tool to improve health or to treat many not communicable chronic diseases. Most common and more achievable exercise in world population is walking. Physical demands in walking may be increase through a greater activation of the upper limbs. AIM The aim was to verify the increase of physical effort due to greater activation of the upper limb during human locomotion. METHODS Four healthy male (aged 27.5±4.4 yrs, height 176.7±12.2 cm, weight 69.6±10.6 kg) performed an incremental treadmill test from 3 km/h up to 7.5 km/h with an increase of 1,5 km/h every 3 min and 1minute of active recovery. This test were performed free (F) and one week later with a new tool (Bit Batt System, BBS) for a greater activation of upper limb. The parameters analyzed were Skin Temperature, Galvanic Skin Response and Energy Expenditure from M&T System by SenseWear Bodymedia. T-test were performed between free test and test with Bit Batt System. RESULTS Skin temperature (degree) were: At 3 km/h 30.7±1.0 (F), 30.9±0.7 (BBS); 4.5 km/h 31.2±0.9 (F), 31.4±0.5 (BBS); 6 km/h 31.4±0.7 (F), 32.0±0.3 (BBS); 7.5 km/h 31.6±0.6 (F), 32.3±0.3 (BBS) p<0.05; recovery 31.7±0.5 (F), 32.3±0.4 (BBS) p<0.05. Galvanic Skin Response (ohm) were: At 3 km/h 0.074±0.029 (F), 0.088±0.033 (BBS); 4.5 km/h 0.097±0.037 (F), 0.119±0.041 (BBS); 6 km/h 0.111±0.039 (F), 0.137±0.043 (BBS); 7.5 km/h 0.137±0.029 (F), 0.179±0.026 (BBS) p<0.05; recovery 0.265±0.025 (F), 0.393±0.028 (BBS) p<0.05. Energy Expenditure (kcal/min) were: At 3 km/h 15.3±2.7 (F), 16.6±2.4 (BBS) p<0.01; 4.5 km/h 19.3±1.2 (F), 20.2±1.6 (BBS) p<0.05; 6 km/h 26.6±4.6 (F), 33.2±3.3 (BBS) p<0.05; 7.5 km/h 41.8±10.2 (F), 44.8±7.2 (BBS); recovery 39.1±9.3 (F), 38.9±5.6 (BBS). CONCLUSION Data relating BBS show that a greater activation of the upper limbs during human locomotion leads to an increase in energy expenditure mainly at walking speeds. For speeds close to the run, the increase is mainly dependent of the Temperature and Galvanic Response of the skin.

INTRODUCTION Physical exercise is an important tool to improve health or to treat many not communicable chronic diseases. Most common and more achievable exercise in world population is walking. Physical demands in walking may be increase through a greater activation of the upper limbs. AIM The aim was to verify the increase of physical effort due to greater activation of the upper limb during human locomotion.
