Physiological effects of a sports rehabilitation program on cerebral palsied and post-poliomyelitic adolescents.
Thirty-four spastic cerebral palsied (CP) post-poliomyelitic (P) adolescents (mean age--17.9 years) participated in a twice-a-week mild conditioning program, lasting 12 months. Nine CP adolescents served as a control inactive group. The post-conditioning submaximal heart rates of the CP active group were significantly lower during 75 and 150 kpm/min work loads on an arm ergometer, compared with the respective values at the beginning of the program. Peak O2 uptake values, directly measured during an all-out arm pedalling test, were improved by some 8% in the CP active group. Neither CP inactive nor P active showed any significant changes attributable to conditioning in physiological variables obtained during the submaximal or maximal tests. Adiposity level of each of the three groups remained unchanged. The mechanical efficiency of all subjects was low (16.2%) and remained so following conditioning.

The effects of intermittent warm-up on 7-9 year-old boys.
Twelve boys, 7-9 years old, who, by use of questionnaires, were found to be ignorant of the concept of "warm-up", performed maximal aerobic and anaerobic tasks 4 min after completing a 15 min intermittent warm-up (WU) (30 sec treadmill run, 30 sec pause). The WU required some 60% of the individual's VO2max, and raised rectal temp. by 0.52 +/- 0.19 degrees C. The aerobic criterion task (CT) was a one-stage bicycle ride at a load predetermined to exhaust the subject after 4 min. The anaerobic CT was a 30 sec all-out ride against resistance of 35 gm/kg BW. Subjects also performed both CT's without any WU. VO2max (aerobic CT), HRmax, as well as total mechanical work output achieved during the aerobic CT, were significantly higher with WU, compared with the non-WU sessions. During the anaerobic CT total revolutions, total power output, as well as peak HR, were significantly higher following WU. It is suggested that the benefits of intermittent WU, as used in this study in young children, can be attributed to physiological rather than psychological mechanisms.
