El objetivo de este estudio fue determinar los efectos de un programa de acondicionamiento de danza aerobica de doce semanas sobre los parametros de composicion corporal de mujeres jovenes. La muestra de 59 mujeres jovenes se dividio en dos grupos, uno experimental y otro control. El grupo experimental estaba compuesto por 29 mujeres (edad 23,1 ± 1,9 anos, estatura 164,4 ± 6,1 cm, peso corporal 62,1 ± 5,6 kg, IMC 23,0 ± 2,2 kg/m2), mientras que el grupo de control estaba compuesto por 30 mujeres (edad 22,7 ± 1,8 anos, estatura 165,3 ± 6,2 cm, peso corporal 59,4 ± 6,3 kg, IMC 21,7 ± 1,7 kg/m2). Para evaluar la composicion corporal, se utilizaron las siguientes medidas: la suma general de los pliegues cutaneos parte superior del cuerpo, la suma general de los pliegues cutaneos parte inferior del cuerpo, la suma general de los pliegues cutaneos de las partes superiores e inferiores del cuerpo, el porcentaje de grasa corporal, el porcentaje de masa muscular en el cuerpo, estatura y peso corporal. Al considerar todas las sumas de los pliegues cutaneos de las mujeres del grupo experimental, observamos una disminucion estadisticamente significativa (p < 0,05) en la medicion final en relacion con la medicion inicial (SPC SUPERIOR ­ 39,35 mm en comparacion con 42,87 mm; SPCINFERIOR ­ 39,35 mm en comparacion con 49,88 mm; SPC TOTAL ­ 76,97 mm comparacion con 92,75 mm). En el caso de porcentaje de grasa corporal, se observo una disminucion en la medicion final en relacion al porcentaje inicial (20,37% en comparacion al 22,66%) lo cual fue estadisticamente significativo (p < 0,05 ). Basado en los resultados de nuestro estudio, podemos concluir que la danza aerobica disminuye el tejido graso subcutaneo y la composicion corporal de las mujeres jovenes.

Cilj ovog istraživanja bio je da utvrdi razlike na polju funkcionalnog fitnesa kod muškaraca starijih od 60 godina. U istraživanje je bilo uključeno 272 ispitanika. Sve ispitanike smo podijelili u pet starosnih kategorija, i to: 60–64 godine bilo je 90 ispitanika (33%), 65–69 godina, 70 ispitanika (26%), 70–74 godine, 50 ispitanika (18%), 75–79 godina, 41 ispitanik (15%) i preko 80 godina starosti bio je 21 ispitanik (8%). Svi ispitanici su proveli bateriju testova pod nazivom senior fitnes test. Test se sastoji od šest mjera fizičkog fitnesa: 1) pokretljivost ramena, 2) pretklon na stolici, 3) osam stopa, 4) ustajanje sa stolice za 30 sekundi, 4) fleksija u zglobu lakta, 5) dvominutni step test. Body mass index pokazuje da su svi ispitanici prekomjerne tjelesne težine bez obzira kojoj starosnoj kategoriji pripadaju. Kod fleksibilnosti ne postoji statistički značajna razlika (p > 0,05) između ispitanika različite starosne dobi nakon 60. godine starosti. Ispitanici se najviše razlikuju po pitanju snage kako donjih, tako i gornjih ekstremiteta. Primijećeno je opadanje snage sa procesom starenja tako da se ispitanici starosne dobi 60-64 godina statistički značajno razlikuju u snazi donjih ekstremiteta (p < 0,05) od ispitanika starih 70–74 i 75–79 godina. Najveća heterogenost zabilježena je u parametrima aerobne izdržljivosti, gdje rezultati progresivno opadaju od 60 godine, gdje su zabilježene najveće vrijednosti (78,60 ± 42,00) do 80. godine starosti (73,68 ± 35,62). U ovoj studiji smo utvrdili da je došlo do povećanja količine masnog tkiva, smanjenja nivoa mišićne aktivnosti, kao i smanjenja mišićne snage i izdržljivosti procesom starenja.

Hypokinesia or low level of physical activity typical for the modern way of living, together with the consumed calories that cannot be burnt, lead to the increased weight which is above the average weight for a particular person. The presence of obesity from the day of birth to the old age is increasing in the world, and it may be stated that it is increasing in Serbia as well. The aim of this research is to establish the difference between height-weight relations and nourishment of seven-year-old pupils, measured in 1988 and 2008. The sample comprised primary school pupils, 7 years of age, from Nis, measured in 1988 and 2008. The number of examinees was 524, 257 boys measured in 1988, 91 boys measured in 2008, 91 girls measured in 1988, 85 girls measured in 2008. The results of this research showed that male pupils measured in 1988 had, statistically significan lower body weight, body mass index, average volume of the chest, skin folds, and had lower levels of fat in the body. Female pupils measured in 1988 had lower values of height, weight, body mass index, average chest volume, skin folds and lower levels of fat. The percentage of normally fed pupils measured in 1988 was 88.3%, while the percentage of those measured in 2008 was 59.3%. The relationship between 1988 and 2008 is 92.3% to 56.5%, in female pupils. The number of obese male and female pupils was significantly increased in 2008.
