News: Research from Institute of Exercise and Health Sciences at University of Basel
Dear readers, we would like to inform you about interesting research.
Scientists from Institute of Exercise and Health Sciences at University of
Basel in Switzerland conducted a research about effects of stair-climbing on balance, gait, strength, resting heart
rate, and submaximal endurance. 39 seniors with average age of 70,5 completed
this experiment.
As it is mentioned in the research paper: "Fall-related injuries in
seniors seriously contribute to increasing health care utilizations and
expenditures (Stevens et al., 2006). Aging-induced declines
of strength, endurance, and balance performance have been reported to
mainly account for severe fall events (Lord, 2007). Prospective studies
revealed that higher levels of general physical activity may reduce
overall morbidity and mortality (Bembom et al., 2009) as well as the
risk of falling between 30% and 50% in seniors (Gillespie et al.,
2012). Seniors should, thus, be encouraged to maintain or increase
habitual physical activity levels (Chodzko-Zajko et al., 2009). In this
regard, multimodal training regimens including strength, balance,
and endurance tasks are considered important to reduce the risk of
fatal and nonfatal falls as well as chronic cardiovascular and metabolic
disease (Gardner et al., 2000)." (Gardner et al., 2000)." (Donath, L., O. Faude, R. Roth a L. Zahner, 2014)
In this case, even everyday activity like climbing a staircase instead of
using an elevator can help. Results of three groups were compared – group of
one- (taking every step, INT1) or twostep strategy (every second step, INT2) and a control
group (CON). Maximal strength and explosive power did not improve significantly
(0.10 < P < 0.78). Resting heart rate was significantly
reduced in INT2 (-8/min) compared with INT1 (0/min, P =
0.02) and CON (0/min, P = 0.03). Compared with CON, perceived
exertion for all intensities (0.007 < P < 0.03) and
submaximal exercise heart rate during moderate uphill walking significantly
decreased (-11/min; P < 0.05) in INT2. Step
counts for forward beam balancing (4.5 cm width) increased in INT2 (P =
0.007) compared with CON.
With more pronounced effects in INT2, stair-climbing
significantly improved resting and exercise heart rates, perceived exertion, and
dynamic balance performance in healthy seniors and may contribute to better
overal fitness, reduced fall risk, and less perceived strain during daily
life activities. From this you can see that even a small effort to change your way of living can lead to significant results.
