Abstract
The health benefit of physical activity (PA) are well known. This study evaluated the PA of 15 male middle-aged adults (53.7 yrs ± 3.5, Hgt: 179 ± 5.9 cm, Wgt: 83.3 ± 9.1 kg) who incidentally participated in a weekend senior baseball league. PURPOSE To determine the relationship between unsupervised daily PA by pedometry and measures of health and performance related fitness (HPRF). METHODS Pedometry measures were determined for 15 consecutive days by subjects wearing a pedometer on the right hip. HPRF measures included grip strength (TG) sit and reach (ROM), % Fat, 37 meter sprint (S), and predicted VO2max via the Rockport Walk Test (RWT). Correlational analysis was by pearson correlation coefficients. RESULTS Average daily steps (5,871.3 ± 2.882) was significantly (P < .05) related (r = .94) to VO2max ml/kg/min (36.6 ±5.9, while Age, Wgt, ROM, S, %Fat, and TG related poorly (r = .03, .19, .12, .12, .24, −.41), respectively. CONCLUSION Pedometry provides a reasonable measure of PA in male middle-age adults. Middle-age adults who participate in weekend baseball require higher behavioral target recommendations in view of their low HPRF.
