Some heartworm medications require a monthly administration, while others work even longer (up to six months with an injectible product called moxidectin). There are many choices of heartworm preventive medications available, from topical products to chewable oral medications; most come in both dog and cat versions. Monthly heartworm preventive medications do not actually stay in your dogâs bloodstream for 30 days. The active ingredients work to kill any larvae that have been in the system for the past 30 days, clearing the body each month.
This is sub-optimal. The glutes are slow twitch dominant by a few percent, but the hamstrings are composed of a whopping 70% fast twitch fibers. The erector spinae are slow twitch dominant by around 6%. This means you should use low reps for the hamstrings, but medium to high reps for the lower back and the glutes.
The first is the muscle spindles. Located within the muscle fibres they monitor changes in muscle length. The stretch reflex is the bodys involuntary response to an external stimulus that stretches the muscle (5) and causes a reflexive increase in muscular activity. It is the muscle spindles that activate this response. When stretching, it is best to avoid this activating the muscle spindles and the stretch-reflex response, as it will limit motion. Static stretching does not elicit the muscle spindles, allowing muscles to relax and achieve a greater stretch. The other important proprioceptors are the golgi tendon organs (GTO).
