The purpose of this study was to determine the effects of 6 weeks of stretching and moderate-intensity resistance training on older adults’ functional fitness. Twenty-two older adults (69 ± 1 year) participated in a resistance-training program, and 15 (70 ± 4 years) participated in a control group. Training involved 3 sessions per week, each consisting of 1 set of 12–15 repetitions of lower and upper body exercises on resistance machines. Before sessions, participants performed 20 min of stretching exercises. A recently developed test battery (Rikli & Jones, 1999) to assess the physical parameters associated with independent functioning in older adults was performed before and after training. The combined stretching and resistance exercise resulted in significant (p≤ .008) improvements on all the functional tests except the 6-min walk. The results indicate that moderate-intensity resistance training in conjunction with stretching can improve functional fitness in older adults, enabling them to more easily perform activities of daily living.

The purpose of this study was to examine the effect of 2 school years (21 months) of a twice-weekly resistance training program on stature, muscle strength, and self-concept among prepubertal boys. The experimental group (E, n = 27) aged 9.2 ± 0.3 yrs, participated in progressive resistance training, while the control group (C, n = 22) aged 9.4 ± 0.3 yrs, participated in standard physical education classes (as advised by the Ministry of Education). Training sessions included 1–4 sets of 3–6 exercises, with 5–30 repetitions/set. The load ranged between 30% and 70% 1RM. No differences were observed in the gain in body height between groups. Muscle strength increased significantly more in E (e.g., knee extensors: 0.51 ± 0.13 to 0.77 ± 0.16 kg/kg body mass), compared with C (0.34 ± 0.12 to 0.54 ± 0.11 kg/kg body mass). One minor injury was reported throughout the study. Initial scores of self-concept were high in both groups, with no training effect. The results demonstrate that among prepubertal boys, a twice-weekly low-to-moderate-intensity resistance training program over a period of 2 school years (21 months) can result in enhancement in muscle strength with no detrimental effect on growth.

The aim of this study was to examine the hormonal and strength responses to different periodization models of resistance training in male athletes. Eighteen experienced resistance trained males were randomly assigned to either a block (BP; n=10; age: 23.7±2.9 yr; body mass: 78.5±11.3 kg; height: 1.77±0.05 m) or weekly undulating (WUP; n=8; age: 26.0±5.7 y; body mass: 78.9±12.4 kg; height: 1.79±0.05 m) periodized resistance training program. Both programs consisted of four-training sessions per week for 15 weeks, and each was equated for training volume. Analysis of variance was used to compare strength performance and changes in hormone response between groups. Salivary samples were taken before and after the first and the last workout of each mesocycle of the training program and assessed for testosterone (T) and cortisol (C). Maximal strength testing occurred before and after the 15-week training program. A greater increase (p=.040) in bench press strength was observed in BP compared to WUP, while no between group differences were noted for lower body isometric strength (p=.168) and lean body mass (p=.344). Significant elevations in T were seen in both groups following the power training phase, while no differences were noted between BP and WUP during any other training cycle. Results indicated that BP stimulated greater gains in upper body strength compared to WUP. In addition, the power phase of training may provide a greater anabolic hormone response.

This study sought to determine if personalized moderate-intensity continuous exercise training (MICT) combined with high-intensity interval training (HIIT) was more effective at improving comprehensive training responsiveness than MICT alone. Apparently healthy, but physically inactive men and women (n = 54) were randomized to a non-exercise control group or one of two 13-week exercise training groups: (1) a personalized MICT + HIIT aerobic and resistance training program based on the American Council on Exercise guidelines, or (2) a standardized MICT aerobic and resistance training program designed according to current American College of Sports Medicine guidelines. Mean changes in maximal oxygen uptake (VO2max) and Metabolic (MetS) z-score in the personalized MICT + HIIT group were more favorable (p < 0.05) when compared to both the standardized MICT and control groups. Additionally, on the individual level, there were positive improvements in VO2max (Δ > 4.9%) and MetS z-score (Δ ≤ −0.48) in 100% (16/16) of participants in the personalized MICT + HIIT group. In the present study, a personalized exercise prescription combining MICT + HIIT in conjunction with resistance training elicited greater improvements in VO2max, MetS z-score reductions, and diminished inter-individual variation in VO2max and cardiometabolic training responses when compared to standardized MICT.

Context:Physical exercise is regarded as a useful tool in the treatment of multiple sclerosis (MS). Generally, physical rehabilitation have been based on the prescription of aerobic exercises, while fewer programs have been aimed at developing muscular strength.Objective:To establish whether the physical fitness of MS sufferers can be improved by a training program for developing muscular strength.Design:Before and after studySetting:University multipurpose roomParticipants:36 patients, all able to walk, belonging to the Leon Multiple Sclerosis Association.Interventions:The physical exercise programme consisted in resistance training sessions, based mainly on callisthenic, or bodyweight, exercises, during six weeks.

Background: Airways resistance and broncho-spasm due to exercise are very common. Factors such as exercise, temperature, humidity, air pollution, and disease affect this complication. This study was performed due to the increase in physical disability of muscle weakness in patients with MS and the lack of information on the effect of different strength training exercises on air resistance. Objectives: The current study aimed to investigate the effect of resistance training with different intensities on airway resistance indices of women with MS. Methods: Thirty six women with Multiple sclerosis who had a disability criterion ranged from 1 to 4 (based on Krutzke’s disability scale) were sampled using the targeted and purposive sampling methods. They were selected based on the initial health conditions and then were randomly assigned to each of the three groups (each consisting of 12 participants). The first group received resistance training for 12 weeks, three sessions a week with intensity 60% 1RM, and the second group received resistance training for 12 weeks, three sessions a week with intensity 80% 1RM. Those in the control group didn’t have an exercise program. Results: Airway resistance indices were measured both before and after 12 weeks of resistance training, airway resistance indices in both groups was significantly decreased, and these changes were significant in both experimental groups as compared to the control group. Conclusions: According to the findings, in addition to improving balance, fatigue, and muscle endurance, high-intensity resistance training had similar effects to moderate-intensity exercise on pulmonary function indices in women with MS.
