Background:Resistance exercise has numerous,well-documented benefits on the health and functional performance of older ***,little information exists on the affective responses to resistance exercise in this *** affective responses can predict continued exercise behavior,examining if and how they differ between resistance exercise intensities and frequencies in older adults may provide important data to improve resistance exercise ***:We monitored the affective responses of older adults when performing high-velocity,low-load(HVLL)or low-velocity,high-load(LVHL)resistance exercise once or twice weekly.A total of 40 moderately to highly active,but resistance-exercise naïve,older adults(60-79 years)completed 1 of 4 randomly assigned progressive resistance exercise conditions:HVLL once weekly(HVLL1:n=10),HVLL twice weekly(HVLL2:n=10),LVHL once weekly(LVHL1:n=10),or LVHL twice weekly(LVHL2:n=10).The Physical Activity Affect Scale,Felt Arousal Scale,Feeling Scale,rating of perceived exertion,Visual Analog Scale,and the Physical Activity Enjoyment Scale were used to assess enjoyment and affective ***:The results from Physical Activity Enjoyment Scale(out of 35)suggest that all exercise conditions were largely and similarly enjoyable to older adults(HVLL1:30.9±2.4;LVHL1:31.9±3.6;HVLL2:30.9±3.5;LVHL2:30.2±3.7)despite greater fatigue(p=0.033;ηp^2p=0.22)and perceived workload(p=0.042;ηp^2=0.20)in LVHL(results from Visual Analog Scale).Conclusion:Moderately to highly physically active older adults may tolerate higher intensities of resistance exercise performed once or twice weekly without experiencing a negative impact on ***,the role that supervision and social interaction played in shaping the participants’responses is unclear.

Can Engineers Lead Again?

Engineering 2016年第1期2卷 19-20页

作者： keith clarke Swansea Bay Tidal Lagoon Future Cities Catapult Forum for the Future

The industrial revolution which transformed Europe, and Britain in particular-was led by engineers. From James Watt to Isambard Kingdom Brunel, the finest engineers combined a whole host of skills and disciplines. They were entrepreneurs, developers, lobbyists, financiers, contractors, designers, manufac- turers, and project managers-all rolled into one. And, above all, they were leaders.
