Effects of athletes’ muscle mass on urinary markers of hydration status
Abstract To determine if athletes’ muscle mass affects the usefulness of urine specific gravity (Usg) as a hydration index. Nine rugby players and nine endurance runners differing in the amount of muscle mass (42 ± 6 vs. 32 ± 3 kg, respectively; P = 0.0002) were recruited. At waking during six conse...

| 520 | |a Abstract To determine if athletes’ muscle mass affects the usefulness of urine specific gravity (Usg) as a hydration index. Nine rugby players and nine endurance runners differing in the amount of muscle mass (42 ± 6 vs. 32 ± 3 kg, respectively; P = 0.0002) were recruited. At waking during six consecutive days, urine was collected for Usg analysis, urine osmolality (Uosm), electrolytes (%$ {\mathop U\nolimits_{[{\text{Na}}^{ + } ]} }%$, %$ {\mathop U\nolimits_{[{\text{K}}^{ + } ]} }%$ and %$ {\mathop U\nolimits_{[{\text{Cl}}^{ - } ]} }%$) and protein metabolites (U[Creatinine], U[Urea] and U[Uric acid]) concentrations. In addition, fasting blood serum osmolality (Sosm) was measured on the sixth day. As averaged during 6 days, Usg (1.021 ± 0.002 vs. 1.016 ± 0.001), Uosm (702 ± 56 vs. 554 ± 41 mOsmol $ kg^{−1} $ $ H_{2} $O), U[Urea] (405 ± 36 vs. 302 ± 23 mmol $ L^{−1} $) and U[Uric acid] (2.7 ± 0.3 vs. 1.7 ± 0.2 mmol $ L^{−1} $) were higher in rugby players than runners (P < 0.05). However, urine electrolyte concentrations were not different between groups. A higher percentage of rugby players than runners (56 vs. 11%; P = 0.03) could be cataloged as hypohydrated by Usg (i.e., >1.020) despite Sosm being below 290 mOsmol $ kg^{−1} $ $ H_{2} $O in all participants. A positive correlation was found between muscle mass and urine protein metabolites (r = 0.47; P = 0.04) and between urine protein metabolites and Usg (r = 0.92; P < 0.0001). In summary, Usg specificity to detect hypohydration was reduced in athletes with large muscle mass. Our data suggest that athletes with large muscle mass (i.e., rugby players) are prone to be incorrectly classified as hypohydrated based on Usg. | ||

At waking during six consecutive days, urine was collected for Usg analysis, urine osmolality (Uosm), electrolytes (%$ {\mathop U\nolimits_{[{\text{Na}}^{ + } ]} }%$, %$ {\mathop U\nolimits_{[{\text{K}}^{ + } ]} }%$ and %$ {\mathop U\nolimits_{[{\text{Cl}}^{ - } ]} }%$) and protein metabolites (U[Creatinine], U[Urea] and U[Uric acid]) concentrations. In addition, fasting blood serum osmolality (Sosm) was measured on the sixth day. As averaged during 6 days, Usg (1.021 ± 0.002 vs. 1.016 ± 0.001), Uosm (702 ± 56 vs. 554 ± 41 mOsmol $ kg^{−1} $ $ H_{2} $O), U[Urea] (405 ± 36 vs. 302 ± 23 mmol $ L^{−1} $) and U[Uric acid] (2.7 ± 0.3 vs. 1.7 ± 0.2 mmol $ L^{−1} $) were higher in rugby players than runners (P < 0.05). However, urine electrolyte concentrations were not different between groups. A higher percentage of rugby players than runners (56 vs. 11%; P = 0.03) could be cataloged as hypohydrated by Usg (i.e., >1.020) despite Sosm being below 290 mOsmol $ kg^{−1} $ $ H_{2} $O in all participants. A positive correlation was found between muscle mass and urine protein metabolites (r = 0.47; P = 0.04) and between urine protein metabolites and Usg (r = 0.92; P < 0.0001).

A positive correlation was found between muscle mass and urine protein metabolites (r = 0.47; P = 0.04) and between urine protein metabolites and Usg (r = 0.92; P < 0.0001). In summary, Usg specificity to detect hypohydration was reduced in athletes with large muscle mass.

Nine rugby players and nine endurance runners differing in the amount of muscle mass (42 ± 6 vs. 32 ± 3 kg, respectively; P = 0.0002) were recruited. At waking during six consecutive days, urine was collected for Usg analysis, urine osmolality (Uosm), electrolytes (%$ {\mathop U\nolimits_{[{\text{Na}}^{ + } ]} }%$, %$ {\mathop U\nolimits_{[{\text{K}}^{ + } ]} }%$ and %$ {\mathop U\nolimits_{[{\text{Cl}}^{ - } ]} }%$) and protein metabolites (U[Creatinine], U[Urea] and U[Uric acid]) concentrations. In addition, fasting blood serum osmolality (Sosm) was measured on the sixth day. As averaged during 6 days, Usg (1.021 ± 0.002 vs. 1.016 ± 0.001), Uosm (702 ± 56 vs. 554 ± 41 mOsmol $ kg^{−1} $ $ H_{2} $O), U[Urea] (405 ± 36 vs. 302 ± 23 mmol $ L^{−1} $) and U[Uric acid] (2.7 ± 0.3 vs. 1.7 ± 0.2 mmol $ L^{−1} $) were higher in rugby players than runners (P < 0.05).

Nine rugby players and nine endurance runners differing in the amount of muscle mass (42 ± 6 vs. 32 ± 3 kg, respectively; P = 0.0002) were recruited. At waking during six consecutive days, urine was collected for Usg analysis, urine osmolality (Uosm), electrolytes (%$ {\mathop U\nolimits_{[{\text{Na}}^{ + } ]} }%$, %$ {\mathop U\nolimits_{[{\text{K}}^{ + } ]} }%$ and %$ {\mathop U\nolimits_{[{\text{Cl}}^{ - } ]} }%$) and protein metabolites (U[Creatinine], U[Urea] and U[Uric acid]) concentrations. In addition, fasting blood serum osmolality (Sosm) was measured on the sixth day. As averaged during 6 days, Usg (1.021 ± 0.002 vs. 1.016 ± 0.001), Uosm (702 ± 56 vs. 554 ± 41 mOsmol $ kg^{−1} $ $ H_{2} $O), U[Urea] (405 ± 36 vs. 302 ± 23 mmol $ L^{−1} $) and U[Uric acid] (2.7 ± 0.3 vs. 1.7 ± 0.2 mmol $ L^{−1} $) were higher in rugby players than runners (P < 0.05). However, urine electrolyte concentrations were not different between groups. A higher percentage of rugby players than runners (56 vs. 11%; P = 0.03) could be cataloged as hypohydrated by Usg (i.e., >1.020) despite Sosm being below 290 mOsmol $ kg^{−1} $ $ H_{2} $O in all participants. A positive correlation was found between muscle mass and urine protein metabolites (r = 0.47; P = 0.04) and between urine protein metabolites and Usg (r = 0.92; P < 0.0001). In summary, Usg specificity to detect hypohydration was reduced in athletes with large muscle mass. Our data suggest that athletes with large muscle mass (i.e., rugby players) are prone to be incorrectly classified as hypohydrated based on Usg.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hypohydration</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Urine specific gravity</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Urine osmolality</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Blood serum osmolality</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Urine protein metabolites</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Urine electrolytes</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Coso, Juan Del</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ávila, Andrea</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Mora-Rodriguez, Ricardo</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">European journal of applied physiology</subfield><subfield code="d">Berlin : Springer, 1928</subfield><subfield code="g">109(2010), 2 vom: 08.

Effects of athletes’ muscle mass on urinary markers of hydration status |
| abstract |
Abstract To determine if athletes’ muscle mass affects the usefulness of urine specific gravity (Usg) as a hydration index. Nine rugby players and nine endurance runners differing in the amount of muscle mass (42 ± 6 vs. 32 ± 3 kg, respectively; P = 0.0002) were recruited. At waking during six consecutive days, urine was collected for Usg analysis, urine osmolality (Uosm), electrolytes (%$ {\mathop U\nolimits_{[{\text{Na}}^{ + } ]} }%$, %$ {\mathop U\nolimits_{[{\text{K}}^{ + } ]} }%$ and %$ {\mathop U\nolimits_{[{\text{Cl}}^{ - } ]} }%$) and protein metabolites (U[Creatinine], U[Urea] and U[Uric acid]) concentrations. In addition, fasting blood serum osmolality (Sosm) was measured on the sixth day. As averaged during 6 days, Usg (1.021 ± 0.002 vs. 1.016 ± 0.001), Uosm (702 ± 56 vs. 554 ± 41 mOsmol $ kg^{−1} $ $ H_{2} $O), U[Urea] (405 ± 36 vs. 302 ± 23 mmol $ L^{−1} $) and U[Uric acid] (2.7 ± 0.3 vs. 1.7 ± 0.2 mmol $ L^{−1} $) were higher in rugby players than runners (P < 0.05). However, urine electrolyte concentrations were not different between groups. A higher percentage of rugby players than runners (56 vs. 11%; P = 0.03) could be cataloged as hypohydrated by Usg (i.e., >1.020) despite Sosm being below 290 mOsmol $ kg^{−1} $ $ H_{2} $O in all participants. A positive correlation was found between muscle mass and urine protein metabolites (r = 0.47; P = 0.04) and between urine protein metabolites and Usg (r = 0.92; P < 0.0001). In summary, Usg specificity to detect hypohydration was reduced in athletes with large muscle mass. Our data suggest that athletes with large muscle mass (i.e., rugby players) are prone to be incorrectly classified as hypohydrated based on Usg. |

A higher percentage of rugby players than runners (56 vs. 11%; P = 0.03) could be cataloged as hypohydrated by Usg (i.e., >1.020) despite Sosm being below 290 mOsmol $ kg^{−1} $ $ H_{2} $O in all participants. A positive correlation was found between muscle mass and urine protein metabolites (r = 0.47; P = 0.04) and between urine protein metabolites and Usg (r = 0.92; P < 0.0001). In summary, Usg specificity to detect hypohydration was reduced in athletes with large muscle mass. Our data suggest that athletes with large muscle mass (i.e., rugby players) are prone to be incorrectly classified as hypohydrated based on Usg.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hypohydration</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Urine specific gravity</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Urine osmolality</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Blood serum osmolality</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Urine protein metabolites</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Urine electrolytes</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Coso, Juan Del</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ávila, Andrea</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Mora-Rodriguez, Ricardo</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">European journal of applied physiology</subfield><subfield code="d">Berlin : Springer, 1928</subfield><subfield code="g">109(2010), 2 vom: 08.
