Male, 55 old-year; three years lower myocardial infarction; stents in the right coronary and anterior descending artery. Pharmacological treatment: metoprolol, hicrochlorothiazide, clopidogrel, telmisartan. he has been performing classic interval training of moderate intensity for three years.
Isokinetic anaerobic power test (IsoAPT) was performed on a dynamometer con-trex LP, 0.6 m/s, con/con alternating, 30s at máximum effort, resting 90s, 2 sets; capilar lactate (Accutrend, Roche) 3 min post-effort; HR, BP, 1 and 3 min HR and BP recovery were measured. WHODAS 2.0 12-questions questionnaire, isometric hand dynamometry, 6-minute walk test and PWC-170 cycloergometer protocol was performed too. Training: IsoAPT, 4 sets, 3 times per week, 12 sessions.
The waist-to-height index decreased (0.56 vs 0.52), the prehensile strength increased (14 to 18 kg), the resting heart rate and blood pressure decreased. All this confers reduction of the general cardiovascular risk. The perception of disability by WHODAS 2.0 at the end was 0 (initial 23). A maximal ergometry was obtained with an increase in VO2 peak (15.2 vs 22.7 ml/kg/min) and adequate cardiovascular parameters recovery. In anaerobic power output, the heart rate remained below 80% of the theoretical máximum (70% max), and all cardiovascular parameters improved (cardiac reserve 41 vs 66 bpm). Lactate remained above the anaerobic threshold, with greater production at the end (5.8 vs 7.7 mmo/L), but with less perception of effort (Borg 13 vs 11); no arrhythmias or ischemia were observed on the electrocardiogram. This program has security comparable to that described in other isokinetic modalities, but requiring more activity as both limbs are simultaneous.
We presents a training with acceptable and safe effects in a patient with low-risk ischemic heart disease, as well as favorable adaptations at the level of peripheral muscle strength and adaptations; with control of prescription variables in the isokinetic device, and shorter duration per session.
