Furthermore, we also investigated the possible impact of the rescue equipment of the towed diver on the lifeguard physiological overload and towing speed. Exercise variables were measured in lifeguards aged 25.5 ± 6. years before and immediately after the swimming a distance of 50 m with a person in tow with or without diving equipment. There were no significant effect of different protocols of towing on V̇O₂. The type of towing protocols have a significant effect on HR, VĖ/V̇O₂ ratio, and blood LA levels. The towing time and the average towing speed during simulated rescue operation were significantly different depending on the type of the towing person’s equipment. Towing a diver wearing only a dry suit significantly reduces the towing time, increases towing speed and may be result in better exercise tolerance and less fatigue for rescuer compared to towing a diver in a full classic or wing diving set.</p>
