Aim. The ­needs of phys­ical ­activity can be ­seen ­through the ­lack of num­bers par­tic­i­pating in reg­ular phys­ical ­activity as ­well as the ­increase in prev­a­lence of cer­tain dis­eases ­such as ­Type II dia­betes (espe­cially in chil­dren), car­di­o­vas­cular dis­eases, and ­some can­cers. ­With the ­increase in pre­vent­able dis­eases ­that are ­caused in ­part by a sed­en­tary life­style, a ­closer ­look ­needs to be ­taken ­into the ­role of ­family inter­ac­tion as a ­means of ­increasing phys­ical ­activity for ­both ­adults and chil­dren. ­Because of the ­many ben­e­fits of phys­ical ­activity in rela­tion to ­health, a ­family ­approach to ­achieving rec­om­mended ­levels of phys­ical ­activity may be ­quite appli­cable.
­Methods. ­Forty vol­un­teers ­were ­recruited ­from the com­mu­nity (20 sub­jects and 20 chil­dren). The vol­un­teers ­played 2 ­games: ­soccer and nerf­ball. ­Data was col­lected ­over 10 min­utes (5 min per ­game). ­Expired air anal­ysis was ­used to cal­cu­late ­energy expen­di­ture and meta­bolic equiv­a­lents (­METs). Descrip­tive sta­tis­tics ­were cal­cu­lated ­along ­with a regres­sion anal­ysis to deter­mine dif­fer­ences ­between the 2 ­games, and an ­ACOVA to deter­mine any sig­nif­i­cant ­effects of age, ­child age, ­gender, and phys­ical ­activity ­level on the ­results.
­Results. For ­both ­games, ­average ­heart ­rate meas­ured approx­i­mately 88%max; ­average ­METs meas­ured approx­i­mately 6, ­average ­energy expen­di­ture meas­ured approx­i­mately 40 ­kcal. Con­clu­sion. ­This ­study ­showed ­that ­adults can ­achieve rec­om­mended phys­ical ­activity ­levels ­through ­these spe­cific activ­ities if sus­tained for approx­i­mately 20 min.
