Short Editorial Cunha Physical Activity in Hypertension in Workers Arq Bras Cardiol. 2020; 114(5):762-763 al. 9 indicate that some differences between LPA and OPA may justify the difference in the observed results, including: 1) OPA with very low intensity and very long duration to improve physical fitness and cardiovascular health; 2) OPA with weightlifting or static postures, which can increase BP; 3) OPA performed without sufficient recovery time; 4) OPA performed with little control by the worker; and 5) OPA that increases inflammation levels. The wrong type of PA can be harmful to health, both in the context of OPA and LPA. 13 Therefore, too much mechanical force can cause a musculoskeletal injury, a too frequent activity can lead to exhaustion and too much time in the standing position can facilitate the appearance of varicose veins in the lower limbs. In contrast, too little strength can cause bone and muscle loss, infrequent exercises can cause cardiorespiratory deconditioning or cardiometabolic health alteration. 13 Thus, the benefits of physical activity, both at work and during leisure, are only manifested when the several aspects of PA are well adjusted, calibrated. The different dimensions of PA (intensity, duration, frequency of postures and different movements) affect different body systems and functions (aerobic capacity, muscle strength, movements, balance, coordination). All these aspects of PA at work should lead to the meeting of one’s “perfect point”, so that their effect in health promotion can occur. 13 In conclusion, PA is beneficial to health and helps to control BP, mainly through the practice of aerobic exercises, but also with resistance exercises. The cumulative effect of different types of PA, as studied by Ribeiro Jr. & Fernandes, 10 contributes to the protection against AH. The OPA should be evaluated carefully and in details, aiming to find optimal physical activity situations, so they can be used for health benefits, and not as a harmful mechanism for the worker. 1.
