Summary

Sarcopenia is a geriatric condition characterized by a progressive decrease in skeletal muscle content and loss of muscle function. Resistance exercise, Taichi exercise and the hybrid exercise program consisting of the two aforementioned methods have been demonstrated could increase the skeletal muscle mass of the elderly with sarcopenia. However, note that the above contents may be performed in a different order in a treatment, equally important but less well understood is the sequence in which it should be performed. Surprisingly, the exercise sequence has not been comprehensively investigated. Therefore, investigators designed a self-ordered exercise program combining resistance exercise, tai chi and a hybrid exercise program to investigate whether the decline in skeletal muscle area could be better overcome and the reversal of sarcopenia in elderly with sarcopenia.

Interventions

Type	Name	Description
BEHAVIORAL	self-determine sequence exercise program	The Taichi exercise utilized the simplified eight styles of Taichi. The resistance training program consisted of three cycles. In the first cycle, investigators used a light load but high repetitions (ranging from 40% to 60% of one repetition maximum and 12-20 repetitions). During the second phase of our training, investigators raised the training load by doing sets of moderate intensity and a medium number of repetitions (ranging from 60% to 80% of one repetition maximum and 5-12 repetitions). In the third cycle, investigators aimed to improve the participants' maximal muscular resistance by using a greater training load and fewer repetitions (ranging from 70% to 85% of one repetition maximum and 5-8 repetitions).

In the third cycle, investigators aimed to improve the participants' maximal muscular resistance by using a greater training load and fewer repetitions (ranging from 70% to 85% of one repetition maximum and 5-8 repetitions). Participants in the RTG completed four sets of each movement, with two to three minutes of rest between each set.
BEHAVIORAL	Taichi exercise and resistance training	The training of the Taichi exercise and resistance training group consisted of two cycles, the first cycle was aimed at learning and consolidating Taichi exercise, and the second cycle was aimed at improving and consolidating. The Taichi exercise and resistance training group was scheduled for 30 min of Taichi exercise per training. The resistance training program consisted of three cycles. In the first cycle, investigators used a light load but high repetitions (ranging from 40% to 60% of one repetition maximum and 12-20 repetitions). During the second phase of our training, investigators raised the training load by doing sets of moderate intensity and a medium number of repetitions (ranging from 60% to 80% of one repetition maximum and 5-12 repetitions). In the third cycle, investigators aimed to improve the participants' maximal muscular resistance by using a greater training load and fewer repetitions (ranging from 70% to 85% of one repetition maximum and 5-8 repetitions).
BEHAVIORAL	Randomly selected exercise program	Participants in the randomly selected exercise program group who chose Yijinjing exercise were required to complete one hour of Yijinjing exercise training, and those who chose Yijinjing exercise hybrid strength training had to complete half an hour of Yijinjing training. The resistance training program consisted of three cycles. In the first cycle, investigators used a light load but high repetitions (ranging from 40% to 60% of one repetition maximum and 12-20 repetitions). During the second phase of our training, investigators raised the training load by doing sets of moderate intensity and a medium number of repetitions (ranging from 60% to 80% of one repetition maximum and 5-12 repetitions). In the third cycle, investigators aimed to improve the participants' maximal muscular resistance by using a greater training load and fewer repetitions (ranging from 70% to 85% of one repetition maximum and 5-8 repetitions).
