Abstract
Alcohol contributes to higher fall risk in people living with HIV (PLWH), yet fall prevention trials for PWH with alcohol use are lacking. To assess the feasibility of conducting a randomized controlled trial of a 10-week online fall prevention intervention tailored for PLWH with alcohol use. The intervention consisted of weekly virtual group discussions, individual phone check-ins, and home exercises. Of those eligible, 53.5% (23/43) enrolled (12 to the intervention and 11 to control). Mean age was 58 years; 82.6% had a past 6-month fall; 65.2% had alcohol use disorder; and 95.7% completed postintervention assessments. The intervention was highly rated (Client Satisfaction Questionnaire-8 score M = 30.4, SD = 1.6) with a wide range of group and individual phone session attendance. Preliminary analyses suggest the intervention may reduce the odds of falling and alcohol use frequency. Findings support the feasibility of a larger randomized trial.

Chen Y, Feng X, Huang L, Wang K, Mi J. Comparative efficacy of concurrent training types on lower limb strength and muscular hypertrophy: A systematic review and network meta-analysis. J Exerc Sci Fit 2024; 22:86-96. [PMID: 38187085 PMCID: PMC10767279 DOI: 10.1016/j.jesf.2023.12.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Revised: 12/12/2023] [Accepted: 12/13/2023] [Indexed: 01/09/2024] Open
Abstract
Objective This study aims to compare, through quantitative analysis, the effectiveness of different endurance training types on increasing lower limb strength and muscle cross-sectional area (MCSA) in concurrent training. Methods This systematic literature search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) [PROSPERO ID: CRD42023396886]. Web of Science, SportDiscuss, Pubmed, Cochrane, and Scopus were systematically searched from their inception date to October 20, 2023. Results A total of 40 studies (841 participants) were included in this meta-analysis. MCSA analysis showed that, compared to resistance training alone, concurrent high-intensity interval running training and resistance training and concurrent moderate-intensity continuous cycling training and resistance training were more effective (SMD = 0.15, 95% CI = -0.46 to 0.76, and SMD = 0.07, 95% CI = -0.24 to 0.38 respectively), while other modalities of concurrent training not. Lower body maximal strength analysis showed that all modalities of concurrent training were inferior to resistance training alone, but concurrent high-intensity interval training and resistance training showed an advantage in four different concurrent training modalities (SMD = -0.08, 95% CI = -0.25 to 0.08). For explosive strength, only concurrent high-intensity interval training and resistance training was superior to resistance training (SMD = 0.06, 95% CI = -0.21 to 0.33). Conclusion Different endurance training types have an impact on the effectiveness of concurrent training, particularly on lower limb strength. Adopting high-intensity interval running as the endurance training type in concurrent training can effectively minimize the adverse effects on lower limb strength and MCSA.

Rodrigues JFC, Mendes TT, Gomes PF, Silami-Garcia E, Amorim FT, Sevilio MNO, Rossi FE, Wanner SP. Reduced running performance and greater perceived exertion, but similar post-exercise neuromuscular fatigue in tropical natives subjected to a 10 km self-paced run in a hot compared to a temperate environment. PLoS One 2023; 18:e0290081. [PMID: 37590220 PMCID: PMC10434900 DOI: 10.1371/journal.pone.0290081] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Accepted: 08/01/2023] [Indexed: 08/19/2023] Open
Abstract
Environmental heat stress impairs endurance performance by enhancing exercise-induced physiological and perceptual responses. However, the time course of these responses during self-paced running, particularly when comparing hot and temperate conditions, still needs further clarification. Moreover, monitoring fatigue induced by exercise is paramount to prescribing training and recovery adequately, but investigations on the effects of a hot environment on post-exercise neuromuscular fatigue are scarce. This study compared the time course of physiological and perceptual responses during a 10 km self-paced treadmill run (as fast as possible) between temperate (25°C) and hot (35°C) conditions. We also investigated the changes in countermovement jump (CMJ) performance following exercise in these two ambient temperatures. Thirteen recreational long-distance runners (11 men and 2 women), inhabitants of a tropical region, completed the two experimental trials in a randomized order. Compared to 25°C, participants had transiently higher body core temperature (TCORE) and consistently greater perceived exertion while running at 35°C (p < 0.05). These changes were associated with a slower pace, evidenced by an additional 14 ± 5 min (mean ± SD) to complete the 10 km at 35°C than at 25°C (p < 0.05). Before, immediately after, and 1 h after the self-paced run, the participants performed CMJs to evaluate lower limb neuromuscular fatigue. CMJ height was reduced by 7.0% (2.3 ± 2.4 cm) at 1 h after the race (p < 0.05) compared to pre-exercise values; environmental conditions did not influence this reduction. In conclusion, despite the reduced endurance performance, higher perceived exertion, and transiently augmented TCORE caused by environmental heat stress, post-exercise neuromuscular fatigue is similar between temperate and hot conditions. This finding suggests that the higher external load (faster speed) at 25°C compensates for the effects of more significant perceptual responses at 35°C in inducing neuromuscular fatigue.

The effects of low-volume combined training on health-related physical fitness outcomes in active young adults. A controlled clinical trial. SPORTS MEDICINE AND HEALTH SCIENCE 2023; 5:74-80. [PMID: 36994175 PMCID: PMC10040378 DOI: 10.1016/j.smhs.2022.12.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Revised: 12/09/2022] [Accepted: 12/31/2022] [Indexed: 01/04/2023] Open
Abstract
The effects of combined training (CT) on improving general health are well known, however, few studies have investigated the effects of low-volume CT. So, the aim of this study is to investigate the effects of 6 weeks of low-volume CT on body composition, handgrip strength (HGS), cardiorespiratory fitness (CRF) and affective response (AR) to exercise. Eighteen healthy, active young adult man (mean ± SD, [20.06 ± 1.66] years; [22.23 ± 2.76] kg/m2) performed either a low-volume CT (EG, n = 9), or maintained a normal life (CG, n = 9). The CT was composed of three resistance exercises followed by a high intensity-interval training (HIIT) on cycle ergometer performed twice a week. The measures of the body composition, HGS, maximal oxygen consumption ( V ˙ O2max) and AR to exercise were taken at baseline and after training for analysis. Furthermore, an ANOVA test of repeated measures and t-test paired samples were used with a p ≤ 0.05. The results showed that EG improved HGS (pre: [45.67 ± 11.84] kg vs. post: [52.44 ± 11.90] kg, p < 0.01) and V ˙ O2max (pre: [41.36 ± 5.16] ml⋅kg-1⋅min-1 vs. post: [44.07 ± 5.98] ml⋅kg-1⋅min-1, p < 0.01). Although, for all measures the body composition had not significant differences between weeks (p > 0.05), nevertheless the feeling scale was positive in all weeks and without significant differences between them (p > 0.05). Lastly, for active young adults, the low-volume CT improved HGS, CRF and had a positive outcome in AR, with less volume and time spent than traditional exercise recommendations.

Abstract
ABSTRACT Pérez-Castilla, A, García-Pinillos, F, Miras-Moreno, S, Ramirez-Campillo, R, García-Ramos, A, and Ruiz-Alias, SA. Selective effect of different high-intensity running protocols on resistance training performance. J Strength Cond Res XX(X): 000-000, 2022-This study aimed to explore the acute effect of 2 high-intensity running protocols (high-intensity interval training [HIIT] and sprint interval training [SIT]) on resistance training (RT) performance and their combined effect on the lower-body maximal neuromuscular capacities. Eighteen healthy subjects randomly completed 3 experimental protocols: only RT, HIIT + RT, and SIT + RT. Characteristics of the RT protocol include 3 back-squat sets of 10 repetitions or 20% velocity loss against 60% of 1 repetition maximum with 3 minutes of interset rest. Characteristics of the high-intensity running protocols include HIIT (4 intervals of 4 minutes at ∼110% of functional threshold power with 3 minutes of interinterval rest) and SIT (6 all-out sprints of 30 seconds with 4 minutes and 24 seconds of interinterval rest). The force-velocity relationship (maximal values of force [F0], velocity [v0], and power [Pmax]) was evaluated at the beginning and at the end of each experimental protocol. The number of back-squat repetitions (p = 0.006; effect size [ES] = -0.96), fastest velocity (p = 0.003; ES = -0.63), and average velocity (p = 0.001; ES = -0.73) were lower for the SIT + RT protocol compared with the RT protocol, but no significant differences were observed between the RT and HIIT + RT (p ≥T0.057; ES ≤.-0.46, except -0.82 for the number of back-squat repetitions) and HIIT + RT and SIT + RT (p ≥T0.091; ES .0-0.35) protocols. The 3 protocols induced comparable decreases in v0 and Pmax (F(2,34) 2,0.96; p ≥ 0.393), but F0 tended to decrease after the SIT + RT protocol and to increase after the RT and HIIT + RT protocols (F(2,34) = 4.37; p = 0.035). Compared with RT alone, the data suggest that SIT deteriorates RT quality and F0 capacity more than long-interval HIIT.
