A Study of the Intervention Effect of a Hybrid Exercise Program on Elderly With Sarcopenia

White Box Modeling of Self-Determine Sequence Exercise Program Among Sarcopenic Elderly: Uncovers a Novel Strategy Overcoming Decline of Skeletal Muscle Area

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: self-determine sequence exercise program; The trial was divided into three cycles, and participants were allowed to choose any one of the a Taichi exercise program, a hybrid program of Taichi exercise and resistance training programs, and resistance training as their intervention content before the start of each cycle. Participants who chose Taichi exercise performed one hour of Taichi exercise for each session, while participants who chose a hybrid exercise program of Taichi exercise and resistance training completed Taichi exercise in the first half hour and resistance training for the second half hour. Participants who chose resistance training performed one hour of resistance training. One hour per training session, three times a week for 24 weeks	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).
EXPERIMENTAL: resistance training; Resistance strength training for resistance exercise and aimed at promoting the greatest hypertrophy response. Training is divided into three cycles, with progressive training load. Resistance exercise intervention three times a week for 24 weeks, one hour each time.	Behavioral: resistance 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). Participants in the RTG completed four sets of each movement, with two to three minutes of rest between each set.
NO_INTERVENTION: control group; The participants in the control group were introduced by nurses to education about sarcopenia and various methods for preventing it, such as consuming more protein through their diet and participating in greater physical exercise.
EXPERIMENTAL: Taichi exercise and resistance training; The trial was divided into three cycles, each lasting eight weeks. Participants performed a hybrid program of Taichi exercise and resistance training of varying duration and intensity in each cycle. Each session lasted one hour, three times a week for 24 weeks.	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).
EXPERIMENTAL: Randomly selected exercise program; The trial was divided into three cycles, and participants were allowed to choose any one of the a Yijinjing exercise program, a hybrid program of Yijinjing exercise and resistance training programs, and resistance training as their intervention content before the start of each cycle. Participants who chose Yijinjing exercise performed one hour of Yijinjing exercise for each session, while participants who chose a hybrid exercise program of Yijinjing exercise and resistance training completed Yijinjing exercise in the first half hour and resistance training for the second half hour. Participants who chose resistance training performed one hour of resistance training. One hour per training session, three times a week for 24 weeks	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).
