Fitness And Health

This paper reports the associations between two global measures of self-perceived fitness and numerous objective fitness and fitness-related measures among 118 British men and women (mean age = 37.9 yr.). Self-perceived fitness, indicated on both a semantic scale of excellent through very poor (I) and an ordinal scale of 1 through 5 (II), was significantly correlated with most fitness and fitness-related variables. For self-perceived fitness I and II, respectively, these included physical work capacity ( rho = 0.48 and 0.51), percent body fat ( rho = −0.27 and −0.39), grip strength ( rho = 0.30 and 0.35), very hard leisure-time physical activity ( rho = 0.47 and 0.35), and frequency of sweating ( rho = 0.54 and 0.45). Stepwise regression analyses yielded Rs of 0.70 and 0.64 for self-perceived fitness I and II, respectively. A significant correlate of self-perceived fitness was self-perceived health ( rho = 0.47), suggesting that people may perceive fitness and health in the same manner. The present data suggest the considerable scope for examining further how people interpret the concept of fitness.

Mz Twins

A comparison of physical capacity, (measured by vital capacity, muscular strength and physical work capacity) in twin boys and controls failed to indicate significant differences. Intrapair correlations showed the MZ twins to be much more similar than the DZ twins in all the capacity measures. The correlations were lower, however, for both MZ and DZ twins for physical work capacity than for the other two capacity variables. When amount of physical exercise during leisure time is kept under control, the DZ twins tend to be more similar for physical work capacity or muscular strength, and the correlations tend to be of the same magnitude for MZ twins. Physical work capacity therefore appears, in this study, to be a more environmentally influenced variable than either vital capacity or muscular strength.

Aim: Th e purpose of our study was to use a time-series design to investigate the eff ect of dietary quercetin supplementation on peak oxygen uptake (VO2peak) and physical work capacity. Methods and organization of the study: Nine recreationally-active men and women completed a treadmill-running graded exercise test (GXT) weekly (excepting wk 8) for 14 weeks. During the fi rst 3 and last 3 weeks, no quercetin supplementation was administered. During weeks 4-11, subjects ingested four soft Q-chews (Nutravail Technologies) per day containing quercetin (1 g/d), vitamin C, vitamin B3 and folic acid. A control group of 5 men were also tested during the fi rst and last week. Research results: VO2peak and test time remained stable throughout the 14 weeks at approximately 3.5±1.1 L/min and 6±1.6 min. Using a one-way repeated measures ANOVA, there was no signifi cant diff erence among means (P > 0.05) for either measure. Th ere was no trend for individual or mean values to increase above baseline during the treatment period. No changes occurred in the control group. Conclusions: We conclude that dietary quercetin supplementation with 1 g/d for 8 wk in non-endurance-trained men and women does not increase VO2peak or physical work capacity.

Activity Questionnaires

Background: Recent research has focused on the potential benefits of physical activity in occupational settings in addition to leisure time. However, occupational physical activity (OPA) differs substantially for occupations that require heavy and repetitive physical work, such as nursing. We explored associations between leisure time and OPA and health outcomes in working nurses and midwives. Methods: Nurses who were enrolled in the Fit For the Future study (New South Wales, Australia) and who completed physical activity questionnaires (n = 4343) were classified according to high (HO) or low (LO) occupational and high (HL) or low (LL) leisure-time physical activity (LTPA): HO performed walking/heavy labor most/all of the time at work; HL met the guidelines of 150 minutes per week moderate to vigorous LTPA, creating 4 categories: HOLL, HOHL, LOHL, and LOLL. Results: HL predicted better self-rated health (unstandardized B = 0.51, 95% confidence interval, 0.44 to 0.57) and lower likelihood of ≥3 sick days in the past 12 months (OR: 0.71, 95% confidence interval, 0.61 to 0.83), whereas HO predicted higher likelihood of ≥3 sick days (OR: 1.17, 95% confidence interval, 1.01 to 1.35), adjusting for all variables. Conclusions: OPA may not confer the same health benefits as LTPA for nurses. Health-promoting interventions should emphasize the importance of achieving adequate moderate to vigorous LTPA for all, including those undertaking substantial OPA.
