2.5. Intervention
APC, CONTRACTIONS
The study protocol explained the TKD and MCT programs in detail (Intervention dosage.APC, Agility and postural control; CF, Cardiorespiratory fitness; Fr, Frequency; HRmax, Maximum heart rate; LL, Lower limbs; MCT, Multicomponent training group; OMNI-RES, OMNI-Resistance Exercise Scale of perceived exertion; PE, Physical exercise; Rep., Repetitions; RT, Resistance training; TKD, Adapted taekwondo group; TPS, Total time per session; ULs, Upper limbs.The central part of the TKD program comprised non-contact exercises, which were broken up into 10 min of basic postures and specific technical foundations for the upper limbs (strikes and blocks) and 20 min of technical foundations for the lower limbs (displacement, postures, and kicks). These exercises were performed individually and in pairs, with and without the use of taekwondo implements (impact pads and shields). In addition, participants practiced these modality-specific choreographies or poomsae for 10 min. The amount of training was measured in sets and repetitions of the specific technical foundations, with a 2-min rest in between sets. Perceived exertion was measured using the Borg scale, which has a maximum rating value of 10 points (The central part of the MCT program was a 40-min circuit of distributed work that included exercises for cardiorespiratory fitness, agility, and postural balance using elastic bands, poles, 2-kg medicine balls, and chairs. The exercises targeted the biceps, triceps, deltoids, latissimus dorsi, quadriceps, hamstrings, glutes, and gastrocnemius, which correspond to the large muscles of the upper and lower limbs. The first training volume (the first 4 weeks) consisted of three sets of 10 repetitions of each muscle activity, with a 2-min rest in between sets. Slow movements, lasting 2 s for concentric and 4 s for eccentric contractions, were used. The volume was increased to four sets of 10 repetitions of each muscular exercise with a 2-min rest in between sets (between weeks 5 and 8). The OMNI-Resistance Exercise Scale of perceived exertion was used to control the resistance training intensity, which ranged from moderate to vigorous (5–8 points) (Assessments and regular sessions of the intervention.
