Experimental studies of physical fitness in relation to age

Effects of intrinsic aerobic capacity, aging and voluntary running on skeletal muscle sirtuins and heat shock proteins

“…Current evidence shows a 10 % per decade decline in VO2max in both men and women (Åstrand 1960;Robinson 1938;Hawkins & Wiswell 2003).…”

Studies of Breathing, Pulmonary Ventilation and Subjective Awareness of Shortness of Breath (Dyspnea) in Neurocirculatory Asthenia, Effort Syndrome, Anxiety Neurosis 1

“…Ventilation and ventilatory efficiency were studied in N.C.A. patients while running at 7.0 miles per hour and while walking at 3.5 miles per hour on a treadmill, Grade 8.9 per cent2 by methods described by Robinson (12). Other aspects of this study have been reported elsewhere (3,13).…”

Maximal aerobic power and anaerobic capacity in cycling across the age spectrum in male master athletes

“…After the peak in young adult age, MAP has been described to decay by about 10 % per 58 decade in the general population after the age of 30 (Åstrand 1973;Dill et al 1967;Maharam et al 1999;Marti and 59 Howland 1990;Marcell et al 2003;Robinson 1938;Rogers et al 1990;Trappe et al 1996), even though we do not 60 know exactly at which age this decay becomes evident.…”

“…Several papers have demonstrated that MAP decreases with ageing in sedentary and active men as well as in well 300 trained male master athletes (Åstrand et al 1973;Dill et al 1967;Maharam et al 1999;Marcel et al 2003, Marti and301 Howland 1990;Pollock et al 1967;Robinson 1938, Trappe et al 1996. It has also been suggested that MAP decreases, …”
