PDF The Study of Safety of Resistance Training by Continuous Mesurement of Blood Pressure in Middle Aged-Men

【Supercategory:7. DESCENTE SPORTS SCIENCE Subcategory:7.19 Vol.19

 The purpose of this study was to investigate the physiological responses during ballistic type (BRT) and non-ballistic type resistance training (non-BRT) by continuous mesurement of systolic (SBP) and diastolic blood pressure (DBP), heart rate (HR), oxygen uptake (VO₂) and blood lactate concentration (HLa), and to discuss the safety of resistance training in middle aged-men. The results were as follows;
 1) SBP, DBP, HR, double product (DP) and rating of percieved exertion (RPE) during non-BRT was significantly higer than those during BRT in lower extremity program.
 2) HLa during non-BRT tended to be relatively high with compared to those during BRT in lower extremity program.
 3) All physiological parameters were almost identical during BRT and non-BRT in upper body programs.
 4) Relatively large differences in VO₂, BP and DP between BRT and non-BRT were noted in higher work load.
 5) SBP, DBP and DP during non-BRT were remarkably higher as compared with those during by bicycle ergometry.
 6) Mean VO₂ and mean %VO₂max during BRT in our subject (IN) were 15.5 ml/kg/min and 45.7%VO₂max, respectively (energy expenditure being 438.7 kcal).
 These results indicate that BRT is considered to be more safe with compared to non-BRT with particular reference to BP response, and that BRT may be effective for developing and maintaining of muscle mass and health related fitness in middle aged-men.
