向骨骼肌提供能量的能力的增加有望有助于更好的运动表现，因此，各种各样的训练方法被用于改善这些能量供应系统。这些方法分为两大类：在给定负荷/强度下的连续运动和在给定负荷/强度下间歇运动，并有恢复间隔。有趣的是，最近的研究表明，在给定的训练集内，从高负荷/高强度开始，逐渐降低运动负荷/高强度的训练方法（逐步减负荷训练）可能会提供一系列的适应性。在阻力训练中，负荷开始时很高，然后随着训练的继续而减少，这有望同时增加肌肉力量、耐力和尺寸。在有氧和无氧代谢系统的训练中，强度开始时很高，然后随着运动的继续而降低，期望同时增加最大无氧功率，无氧能力和有氧能力。因为逐步减少负荷训练在每次负荷/强度之间没有恢复间隔，所以每次训练的效果在很短的时间内（几分钟）就能达到。然而，只有很少的证据支持逐步减少负荷训练的效果；因此，需要更大样本的进一步研究。
An increased ability to supply energy to skeletal muscle is expected to contribute to greater athletic performance, and therefore, a variety of training methods are used for improving these energy supply systems. These methods are classified into two broad categories: a bout of continuous exercise at a given load/intensity and intermittent bouts of exercise at a given load/intensity with recovery intervals. Interestingly, recent work suggests that a training method which starts at a high load/intensity and gradually decreases the exercise load/intensity within a given training set (stepwise load reduction training) may provide a range of adaptations. In resistance training, the load starts off high and is then reduced as the set continues which is expected to simultaneously increase muscle strength, endurance, and size. In training focused on aerobic and anaerobic metabolic systems, intensity starts off high and is then reduced as the exercise continues which is expected to simultaneously increase maximal anaerobic power, anaerobic capacity, and aerobic capacity. Because stepwise load reduction training has no recovery intervals between each load/intensity, the training effects are achieved within a short time per session (several minutes). However, only minimal evidence exists to support the effects of stepwise load reduction training; therefore, further studies with larger samples are needed.
