Impact of Manual Gravel Extraction on Practitioners’ Body Composition and Spirometric Values

The aim is to evaluate the effects of manual gravel extraction on body composition and spirometric values in divers screeners. Our study an experimental exploratory type, concerned 30 workers distributed as follows: 15 variables were carried out before after four months activity. results show that practice gravelling has more significant than scouts anthropometry (weight 54.42 ± 5.48 kg vs 58.62 3.83 kg; Body Mass Index, 19.64 1.31 kg·m-2 20.46 1.89 kg·m-2), (fat mass 16.70 6.57 20.44 2.06; lean 40, 74 5.09 39.90 8.87; Mineral Bone 30.99 7.31 31.87 4.87; Water 4.90 3.13 5.44 0.79) spirometry (Forced Respiratory Flow 25 tiers: 2.87 1.35 4.36 1.89). These may explain fact have specific spots with higher intensities volumes This mercantile activity requires super maximum efforts becomes constraining. deserves be continued years come diet energy expenditure these practitioners.
